At the same time, the globally sustained hypoxic pulmonary vasoconstriction allows for a limit on the shunt effect and maintains gas exchanges. Such mechanisms may account for the alterations of capillary-alveolar function coexisting with normal

blood gases that was observed in our lungs treated with 30 μM of CsA. A possible limit encountered in our study might be the short ischemic time (135 ± 21 minutes) to which our lungs have been exposed. Indeed, a longer ischemia may provoke a more severe IRI and perhaps give the opportunity for the CsA to emphasize its positive effects. Nevertheless, the duration of ischemia in our model was similar to several other studies performed with CsA [15, 25, 30]. A possible bias may also be related to the induction of anesthesia with Isoflurane learn more in live animals. Indeed, several works show that halogen gases inhibit the MPTP [10, 23, 31, 34], which could interfere with the CsA action in the prevention

of IRI. This preventive action was expected for Sevoflurane [10, 31], while Isoflurane showed contrasting results [23, 34]. In our protocol, Isoflurane was only used for the induction of general anesthesia before euthanasia and lung procurement surgery. As observed in the exhaled gas analysis we assumed that there was almost no gas left in the alveoli at reperfusion time. Moreover, Isoflurane has been used in every group, thus limiting the effects of possible drug interference in the results analysis. IRI prevention is a major challenge in lung transplantation. In our pig EVLP model, CsA showed a dose-dependent

improvement in PaO2/FiO2 ratio that may be related to a parallel enhancement of hypoxic pulmonary vasoconstriction. Low Selleckchem Talazoparib doses of CsA showed a non-significant trend toward an improvement in capillary-alveolar membrane Neratinib clinical trial injury. Lungs treated with high doses of CsA (30 μM) presented an aggravation in lung permeability and cytokines concentrations, suggesting a deleterious imbalance between the possible beneficial properties of CsA on IRI cells and their hemodynamic effects in microvascularization. Further studies should focus more on lungs subjected to longer ischemia and treated with low or moderate doses of CsA. We evaluated for the first time the effects of CsA on IRI in ex vivo reperfused pig lungs. Our data suggests a possible deleterious imbalance between the beneficial cell properties of CsA and its hemodynamic effects on microvascularization. For future experiments, it would be interesting to focus more on smaller doses of CsA which might limit hemodynamic drawbacks on lung microcirculation, while keeping their beneficial cellular effect on IRI. Unlike our experiment, in which the length of cold ischemia was limited, other experiments should test CsA in various cold ischemic time situations (i.e., broad spectrum of IRI severity) for highlighting the efficacy of CsA.

To assay T-cell responses in vitro, purified CD4+ and CD8+ T cell

To assay T-cell responses in vitro, purified CD4+ and CD8+ T cells (2 × 105/well) were cultured

for 2 days with increasing doses of hgp100 peptide (for spleen cells of pmel-1 transgenic mice), concanavalin A (Sigma-Aldrich, St Louis, MO), or ELISA plates pre-coated with various doses of anti-CD3 and DC-HIL-Fc or control immunoglobulin. After pulsing with [3H]thymidine (1 μCi/well) in the last 20 hr of the culture period, cells were collected and counted for [3H] radioactivity. Culture supernatant was also harvested and stored at − 85° until required for assaying IL-2, interferon-γ and tumour necrosis factor-α using mouse ELISA kits (BD Pharmingen). The CD4+ T cells (1 × 106) were labelled with 1 μm carboxyfluorescein diacetate succinimidyl find more ester (CFSE; Molecular Probes, Eugene, OR) in Dulbecco’s PBS at 37° for 15 min. After another 30 min of incubation in culture medium, labelled T Vemurafenib ic50 cells were cultured in ELISA wells pre-coated with anti-CD3 antibody (1 μg/ml). At different time-points thereafter, cells were examined for asynchronous cell division by flow cytometry.[16] Bone-marrow-derived DC (BMDC) were harvested

from day 6 cultures of BM cells isolated from BALB/c mice with 10 ng/ml granulocyte–macrophage colony-stimulating factor[17] and used as stimulators. CD4+ T cells purified from KO or WT C57BL/6 mice served as responders.[12] A constant number of BM-DC (5 × 104 cells) was mixed with varying numbers of CD4+ T cells in 96-well plates and cultured for 3 days. T-cell activation was measured by IL-2 production and [3H]thymidine incorporation. To examine the impact of SD-4 deletion

on the reactivity of CD8+ T cells to APC co-stimulation, BMDC (2 × 104 cells/well) prepared from BM cells of WT mice were pulsed with hgp100 peptide (1 μg/ml) and co-cultuerd with varying numbers of pmel-1 CD8+ T cells (0 × 105 to 2 × 105 cells/well) for 72 hr. To examine the effect of SD-4 deletion on APC capacity of DC, BMDC prepared from KO or WT mice were seeded on 96-well plates (1 × 103 to 40 × 103 cells/well), and pulsed for 3 hr with OVA323–339 peptide (2 μg/ml).[18] Cultured DC were added to CD4+ T cells (1 × 105/well) purified from the spleens of OT-II transgenic mice. FER One day after co-culture, IL-2 in the culture supernatant was measured by ELISA. Recipient BALB/c mice were treated with antibiotic water (sulfomethoxazole-trimethoprim; Hi-Tech Pharmacal Co., Inc. Amityville, NY) from 3 days before γ-irradiation daily through until day 28. On day 0, recipients were subjected to total body γ-irradiation (6 Gy) and, within 24 hr, were injected via the tail vein with 1 × 107 T-cell-depleted BM cells (from WT mice) and 5 × 105 splenic T cells purified from three KO or WT mice. T-cell depletion was performed using biotinylated anti-Thy1.

We previously reported that a single nucleotide polymorphism (SNP

We previously reported that a single nucleotide polymorphism (SNP), rs2268338, within the gene encoding ACCβ was associated with susceptibility to diabetic nephropathy in Japanese patients with type 2 diabetes. Although subsequent functional analyses suggested that increased expression of ACCβ in the kidney contributed to susceptibility to the disease, its pathological significance has not been fully elucidated yet. Methods: To know the role of ACCβ in the pathogenesis of diabetic

nephropathy, we examined the effect of ACCβ overexpression on podocyte injury using podocyte-specific ACCβ transgenic (TG) mice and ACCβ-overexpressing cultured murine podocytes. Results: TG mice showed normal renal manifestation under non-diabetic condition. However, 12 weeks after induction of diabetes Dorsomorphin nmr by streptozotocin injection, the increase of urinary albumin excretion was exacerbated in TG mice, RG7420 accompanied by a decrease in the expression of synaptopodin in podocytes,

compared to wild-type mice. In cultured murine podocytes infected with adenovirus vectors encoding ACCβ, the expression of synaptopodin and podocin decreased under high glucose condition, but not under normal glucose condition. Furthermore, overexpression of ACCβ under high glucose condition resulted in reorganization of stress fibers, increased production of cytokines such as MCP-1, IL-6, TNF-α and VEGF, and induction of apoptosis in the murine podocytes. AMP-activated protein kinase (AMPK) is the main kinase regulator of ACCβ, which inactivates ACCβ through the phosphorylation

of serine residues on ACCβ. The AMPK activation by 5-aminoimidazole-4-carboxamide-1-beta-4-ribofuranoside (AICAR) ameliorated ACCβ-induced decrease in the expression of synaptopodin and podocin, reorganization of stress fibers, increased production of cytokines, and induction of apoptosis under high glucose condition in the murine podocytes. Conclusion: From these observations, it is suggested that excess of ACCβ contributes to exacerbation of podocyte injury in diabetic nephropathy, and the regulation of AMPK/ACCβ pathway may be a new therapeutic strategy to prevent podocyte injury in patients with diabetic nephropathy.

2B), suggesting that also this cytokine gene is directly or indirectly targeted by NAB2. To validate our findings that exogenous NAB2E51K diminishes TRAIL induction, we transfected CAL-1 cells with siRNA against NAB2. We achieved a mere 30%

reduction in NAB2 expression with siRNA, possibly due to the high basal expression levels of NAB2 (Supporting Information Fig. 3B). Nonetheless, we observed a slight reduction of CpG-mediated TRAIL induction, while the induction of CD40 LBH589 concentration remained unaffected (Supporting Information Fig. 3A and C). We next determined whether the reduced TRAIL expression in CAL-l-1-NAB2E51K cells affected their capacity to induce cell death. Compared with CAL-l-1-NAB2 or CAL-l-1-EV, CpG-activated CAL-l-1-NAB2E51K cells were indeed less potent in inducing apoptosis of TRAIL-sensitive Jurkat cells as assessed by AnnexinV expression of the target cells (Fig. 3F; p = 0.020 and p = 0.009). Similar results were found when Caspase-3 activation was measured in Jurkat cells (Supporting Information Fig. 4). Together, these results demonstrate that NAB2 is directly involved in TRAIL induction upon TLR9/7-mediated Seliciclib clinical trial pDC activation, and that blocking

its activity diminishes pDC cytotoxicity. We next assessed which molecules mediate NAB2-dependent TRAIL induction in pDCs. Therefore, we blocked PI3K, p38MAPK, or NF-κB signaling in CpG-activated CAL-1 cells with inhibitors chosen based on their activity without compromising the cell viability (Supporting Information Fig. 5A and B). Interestingly, PI3K signaling was essential for NAB2

induction upon CpG stimulation of pDCs as determined by pretreating CAL-1 cells with the inhibitor PI-103 (Fig. 4A; p < 0.0001). PI-103-treated CAL-1 cells also failed to express TRAIL (Fig. 4C and E), supporting our hypothesis that NAB2 induces TRAIL expression in pDCs. Importantly, the induction of NAB2 and TRAIL mRNA was also significantly blocked by PI-103 in primary pDCs upon CpG stimulation (Fig. 4B and D; p < 0.01 and p < 0.05). Of note, the PI3K-mediated NAB2 induction was independent of mTOR as treatment with Rapamycin did not significantly block the increase of NAB2 mRNA upon CpG stimulation (Supporting Cyclin-dependent kinase 3 Information Fig. 5C). Blocking p38MAPK with SB203580, or blocking NF-κB with BAY11-7082 had no effect on NAB2 induction (Fig. 4A; p = 0.38 and p = 0.09). However, p38MAPK inhibition significantly blocked TRAIL expression (Fig. 4C and E; p < 0.01), suggesting that (i) p38MAPK acts independently of PI3K/NAB2 signaling to induce TRAIL, or that (ii) p38MAPK feeds into the same signaling pathway, but downstream of NAB2 activity. In conclusion, we show that PI3K signaling is required for CpG-mediated NAB2 expression and its downstream target TRAIL. We observed that NAB2E51K only partially blocked TRAIL induction. Interestingly, CAL-1-NAB2E51K cells displayed two peaks of TRAIL expression rather than a uniform decrease (Fig. 3C).

These results suggested that the NKG2C genotype might modulate the proliferation and/or survival of circulating NKG2C+ cells, ultimately influencing the magnitude and/or persistence of the NKG2C+ expansion. Functional consequences of gene copy number variation have been reported for some immunoreceptors [58, 59]. This view would indirectly reinforce the hypothesis of an active involvement of the activating KLR in this process. On the other hand, the basis for the association of the NKG2C genotype with the

absolute numbers of NKG2A+, CD161+, and total NK cells, that appeared reduced in NKG2C+/− as compared to NKG2C+/+ children, is uncertain. In summary, the opportunity of studying this rather exceptional cohort, despite its limitations Selleckchem PR 171 (e.g., cross-sectional study, small size, and restricted sample Proteases inhibitor volumes), provides novel insights on the influence of HCMV on the homeostasis of the NK-cell compartment in children, particularly in congenital infection. Further studies are warranted to confirm these observations in a larger cohort, to assess whether

they stand in HCMV-positive adults and, eventually, to identify the mechanisms underlying the influence of the NKG2C genotype on the dynamics of the NK-cell response to HCMV infection. Children participating in this study were enrolled at the Pediatric Infectious Diseases Unit at Hospital de Sant Joan de Déu (Barcelona, Spain). Congenital HCMV infection was defined by the detection of

HCMV DNA (either from urine, blood, and/or neonatal dried blood samples), except for a single case defined by detection of CMV-specific IgM antibodies within the first 3 weeks of life. A control group of healthy children without known congenital HCMV infection and referred to the laboratory for presurgical routine blood analysis were recruited. ADP ribosylation factor The study population included four pairs of dizygotic twins: Two with congenital infection, one with a single infected sibling, and a fourth pair noninfected. The study was approved by the Research and Ethics Committee at Hospital de Sant Joan de Déu and informed consent was obtained from parents prior to inclusion. Children with congenital HCMV infection were divided by conventional clinical criteria in symptomatic and asymptomatic. In our series, clinical manifestations at birth associated to symptomatic congenital HCMV infection included: intracranial calcifications (53.3%), sensori-neural hearing loss (53.3%), microcephaly (46.7%), splenomegaly (40%), thrombocytopenia (40%), hepatomegaly (33.3%), petechiae (33.3%), purpura (26.7%), jaundice (20%), intrauterine growth restriction (20%), and chorioretinitis (13.3%) (Supporting Information Table 1).

In particular, tissue-selective recruitment of immune cells to cu

In particular, tissue-selective recruitment of immune cells to cutaneous tissues, a complex multistep cascade mediated by a large variety of cytokines, chemokines, and adhesion molecules, is thought to have a pivotal role [28, 29]. Among adhesion molecules, induction of ICAM-1, a ligand for LFA-1- and Mac-1 molecules, on the surface of epidermal keratinocytes contributes to infiltration and retention of T-cell populations in the skin, and has been proposed as an important regulator

in skin immune reactions [30]. In this regard, we found that the reduced expression of ICAM-1 in PS-5-treated keratinocytes resulted in impaired adhesiveness of T cells learn more to IFN-γ-activated keratinocytes in an in vitro cell-contact model. T-cell recruitment in inflamed skin tissue is also due to the release of a set of proinflammatory chemokines, including CXCL10 and CCL2, by cytokine-activated Stem Cells inhibitor keratinocytes [4, 31]. In line with this knowledge, in this study, we demonstrated that the migratory ability of T lymphocytes toward sups from keratinocytes pretreated with PS-5 and activated by IFN-γ is drastically reduced compared with that observed in supernatants from control cells. Finally, we confirmed the antiinflammatory

action of PS-5 on IFN-γ signaling by an ex vivo approach based on the use of Non-specific serine/threonine protein kinase IFN-γ-activated explants of human skin treated with PS-5 mimetic and compared to those treated with

control peptide. We found that, other than inhibiting STAT1 phosphorylation in the epidermis of organ cultures of normal human skin, PS-5 peptide impaired the epidermal expression of the inflammatory ICAM-1 and HLA-DR membrane molecules, as well as that of the CXCL10 chemokine, corroborating the effectiveness of this SOCS1 mimetic peptide in reducing the inflammatory responses elicited by IFN-γ-activated human keratinocytes. Increasing evidence suggests that JAK proteins might be a viable target for immunosuppressive drugs against psoriasis and other immune-mediated skin diseases, and the design of potent and selective JAK2 chemical inhibitors could be crucial for the development of optimized therapeutics with minimal adverse physiological effects [32, 33]. On the other hand, limited information concerning the use of peptido-mimetics in inflammatory skin diseases, including psoriasis, is available, likely due to the short-term in vivo stability of these molecules. In this regard, a unique demonstration of the effectiveness of the topical application of antiangiogenic peptides based on pigment epithelium-derived factor in improving psoriasis exists [34].

RORγt-deficient mice completely lack LTi cells and, as a conseque

RORγt-deficient mice completely lack LTi cells and, as a consequence, Rorγt−/− mice fail to develop lymph nodes, Peyer’s patches and ILFs [[5]]. In Rorγt−/− mice, numbers of IL-22-producing ILCs, which express NKp46, are severely reduced as well as

is their capacity to produce IL-22, whereas NK-cell numbers are unaffected [[30, 35, 41]]. The fact that RORγt is required for the development of both IL-17- and IL-22-producing Th17 cells [[45]] and ILCs reinforces the idea that RORγt+ ILCs are the innate equivalent of Th17 cells. AhR is a ligand-dependent transcription factor that belongs to the family of bHLH PER-ARNT-SIM transcription factors. www.selleckchem.com/products/PD-0325901.html AhR acts as a sensor of a variety of chemicals, including environmental toxins such as 2, 3, 7, 8-tetrachlorodibenzo-p-dioxin (TCDD),

and phytochemicals such as indol-3-carbinol, produced by cruciferous vegetables including cauliflower, cabbage, and broccoli LBH589 manufacturer [[48]]. Endogenous ligands have been identified as well, for instance the tryptophan photoproduct 6-formylindolo-(3,2-b)-carbazole (FICZ). In the cytoplasm, AhR is a component of a complex that includes chaperones like hsp90 and from which AhR is dissociated upon its activation by ligand binding. AhR associates with the AhR nuclear transporter (Arnt) prior to translocation to the nucleus to bind to promoters of a variety of genes (reviewed in [[48]]). Only recently was a role for AhR in immunity identified. In mice, AhR controls the differentiation of Th17 cells [[49]], and negatively affects the development of Treg cells [[50]]. Inhibition of Th17-cell differentiation by T cell-specific deletion of Progesterone AhR resulted in the amelioration of collagen-induced arthritis, indicating that over-stimulation of AhR can result in pathology [[51]]. Interestingly, AhR controls the production of IL-22 by T cells, as ablation of AhR in mice completely eliminated the capacity of Th17 cells to produce IL-22 [[49, 52]]. Furthermore, AhR is involved in IL-22 production by Th22 cells in humans [[52]]. More recently, another activity

of AhR emerged when it was found that AhR controls the maintenance of gut epithelium-residing CD8αα+ TCRαβ and TCRγδ cells (collectively denoted as intraepithelial lymphocytes (IELs)). Genetic ablation of AhR resulted in specific loss of IELs [[53]]. Interestingly, dietary components, in particular indol-3-carbinol, serve as ligands for AhR. Furthermore, these dietary products have been shown to be important for IEL maintenance, since mice fed with a vegetable-free diet showed reduced numbers of these cells [[53]]. Recent work has established that AhR is not only important for the maintenance of IELs, but also for both LTi cells and the ILC22 subset that reside in the gut. Several groups reported that AhR-deficient mice had clearly reduced numbers of Rorγt+ ILCs, including LTi cells and ILC22 cells, in the gut [[54-56]].

“A 74-year-old man gradually developed muscular weakness in the upper extremities, followed by dyspnea and dysarthria over a 6-month period. He was admitted to our facility and diagnosed as having amyotrophic lateral sclerosis (ALS) based on clinical and neurophysiological findings. Two months later, transtracheal positive pressure ventilation (TPPV) was started. During his clinical course, orthostatic hypotension occurred a few times. He also had two episodes of transient cardiac arrest, and he died 15 months after disease onset. At autopsy, the brain, weighing 850 g, showed diffuse selleck screening library cortical atrophy, preferentially involving the frontal

lobes. Microscopic findings included severe loss of neurons in the motor cortex, the motor nuclei of the brainstem and the anterior horns of the spinal cord, and mild loss of axons and myelin in the corticospinal tract. Trans-activation response DNA protein 43 (TDP-43) immunoreactive cytoplasmic inclusions, the pathognomonic findings for ALS, were noted in the nucleus facialis, nucleus ambiguus, and in the anterior horn of the spinal cord. In addition, Lewy bodies and Lewy neurites were found in the brainstem and in the for nucleus

intermediolateralis of the thoracic cord. The concomitant alpha-synuclein pathology may have been partly related to possible autonomic dysfunction underlying the two episodes of cardiac arrest. “
“We present a first case of concurrent tumors consisting of schwannoma and meningioma arising at the same spinal level in a patient without neurofibromatosis. A 49-year-old man without clinical evidence of neurofibromatosis presented with a 5-month history of right neck pain. MRI demonstrated an extradural tumor involving the right-sided C2 nerve root with a small intradural component. T1- and T2-weighted and contrast-enhanced MRI could not differentiate the intradural tumor as different from the extradural tumor. Total removal of the tumors was performed. No contiguity of the extradural tumor with the intradural tumor was seen. The intradural tumor attached strongly to the dura mater around the C2 nerve root exits. Intraoperative pathological diagnosis confirmed the extradural tumor as schwannoma and the intradural tumor as meningioma.

For the triple regimens, analyses of the challenge virus loads we

For the triple regimens, analyses of the challenge virus loads were carried not only in splenocytes, where respective 2.7- and 5.5-fold decreases were detected for the DCM and DMC regimens (Fig. 4D), but also in the pooled superficial cervical and

MLNs and thymus. In all of these nonsplenic sites, a considerable clearance of the EcoHIV/NDK virus was detected (Fig. 4E). At 42 days postvaccination, in vivo killing of AMQ peptide-pulsed selleck chemicals llc and re-infused splenocytes showed close to 100% killing efficiency by T cells elicited by both triple regimens (Fig. 4F). Finally, to assess the longevity of the triple vaccine-induced responses, the third subgroup of animals receiving either the DCM or DMC regimens was rested for 115 days prior to the late surrogate virus challenge. Collected pooled PBMCs maintained polyfunctionality upon the AMQ peptide restimulation and the IFN-γ+-cell frequencies remained at respective 5.6 and 2.2% of total CD8+ cells for the DCM and DMC regimens (Fig. 5A). After challenge and measured in spleen, these frequencies rose to means of 9.6 and 6.7%, respectively (Fig. 5B). In the same animals, the DCM- and DMC-induced memory T cells decreased the EcoHIV/NDK DNA copy numbers 3.5-

and 5.2-fold, respectively. Using ANOVA analysis, the means of the challenge virus loads among individual treatments were significantly different, but in pairwise comparisons, this significance was lost after the Bonferroni adjustment (Fig. 5C). Thus, a sequential combination of three different vaccine modalities into a single regimen induced robust, durable, and polyfunctional CD8+ INK 128 purchase T-cell responses. It remains that the real benefit of triple regimens may only become apparent in more challenging situations such as protection of humans against HIV-1. Finally, we assessed the AMQ-specific,

IFN-γ-producing CD8+ T cells for expression of proliferation-promoting IL-2, L-selectin CD62L, memory marker Rebamipide IL-7 receptor α-chain CD127 and CD27, which is required for generation and maintenance of T-cell immunity and is lost from terminally differentiated effector cells. Central memory (TCM), but not effector memory (TEM), T cells possess ability to express high levels of CD62L, have a high proliferative potential, and are primarily found in lymphoid tissue. Thus in spleen for both DCM and DMC regimens, the AMQ-specific postchallenge responses increased from the peak to the memory phase for IL-2 production and CD62L and CD127 expression (Fig. 6A). Memory PBMCs prior to the challenges differed from immune splenocytes the most in lower levels of IL-2 and higher expression of CD62L and CD27 (Fig. 6B). In addition to memory markers, vaccine-elicited CD8+ T cells were also analyzed for expression of the α4β7 adhesion molecule linked to migration of lymphoytes to the GALT. Vaccine-induced T-cell population expressing low level of α4β7 was found among immune splenocytes (Fig. 6C), but not PBMCs (Fig. 5D).

918) In the group

918). In the group CP-673451 datasheet with high expressors, the cytokine answer decreases after glutamine supplementation on average by 17% (Table 2). The IL-2 release in

whole blood samples after stimulation with PMA and ionomycin in relation to the IL-2 genotypes with and without glutamine supplementation is shown in Table 3. The T/T genotype was detected in 47% of the probands, the G/T genotype in 46% and the G/G genotype in 7% of the cases (Table 6). Glutamine supplementation increased IL-2 release in the first tertile of low cytokine expressors. The increase in IL-2 release could not be attributed to a clear distribution of genotypes in this expressor group. A similar situation is also found in the statistics of the medium expressors in the second tertile. The addition of glutamine increased the cytokine release compared to the IL-2 release without glutamine supplementation but it appears that also in this tertile the genotype does not increase the sensitivity of the cytokine release to glutamine. When analysing of the third tertile with high expressors, the glutamine supplementation decreases the release of cytokines, and the genotype does not affect the release of IL-2 either with or without glutamine supplementation. In summary, one can say that there is no significant interaction of the genotype

to the IL-2 release. In addition to this, there is no significant relationship JQ1 order between the interaction of IL-2 genotypes and the IL-2 release under the influence of glutamine in our collective (n = 91). A stimulating effect of glutamine on the IL-2 release in the first and second tertile of low and medium expressors was HSP90 independent of the genotype identified. The TNF-α release in dependence of glutamine supplementation is shown in Table 4. Depending on the level of low, medium and high cytokine release, the TNF-α release was also divided into tertiles with low, medium and high cytokine expressors. The analysis of the tertiles shows that the TNF-α release is increased by a glutamine supplementation in the first

tertile (low expressors) by 23% and decreases in the second and third tertile (medium and high expressors) by 9% and 11% (Table 4). The variations of the TNF-α release are very large in all tertiles, so no clear correlation between the amount of glutamine concentration and the levels of a TNF-α cytokine release can be determined. The glutamine supplementation effects on the entire subject panel (n = 87), a reduction in TNF-α release of 6%. No effect of glutamine on the TNF-α release can be shown. The TNF-α release in whole blood after stimulation with PMA and ionomycin in relation to the TNF-α genotypes with and without glutamine supplementation is shown in Table 5. In 66% of the cases in our collective, the G/G genotype was found. The G/A genotype was detected in 28% and the A/A genotype in 6% of the cases (Table 6).
