BACKGROUND: Cytokines are fundamental elements in mediating and stimulating the immune response against tuberculosis (TB). Growing evidence indicated that polymorphisms in the interleukin-17 (IL-17) A and F genes are implicated in TB. OBJECTIVES: This meta-analysis was aimed to re-evaluate and update the relationship between IL-17A rs2275913 G/A and IL17F rs763780 T/C polymorphisms and TB risk. METHODS: Using inclusive searches of the PubMed, MEDLINE, EMBASE, Web of Science and Elsevier Science Direct, we identified outcome data from all articles estimating the association between IL-17 A and F polymorphisms and TB risk...

BACKGROUND: Suppressor of cytokine signaling (SOCS) proteins are crucial negative regulators in many signaling pathways and are implicated in the pathogenesis of infectious diseases. The purpose of this study was to uncover possible associations of common polymorphisms within SOCS genes with infectious outcomes after traumatic injury. METHODS: A total of 1087 trauma patients (Chongqing cohort 806 and Yunnan cohort 281) were recruited and followed up for the development of infectious outcomes, such as sepsis and multiple organ dysfunction syndrome (MODS)...

Poor clinical responses to checkpoint blockade with anti-CTLA-4 and anti-PD-1 antibodies in melanoma have recently been associated with acquired IFNγ resistance that protects tumor cells from the antiproliferative and pro-apoptotic cytokine activity. IFNγ-resistant melanoma cells very often lack functional expression of the IFNγ signaling pathway gene JAK2 due to gene deletions or inactivating gene mutations. Analyzing melanoma cell lines (n = 46, applying next-generation targeted sequencing and single nucleotide polymorphism arrays) as well as available genomic data sets from The Cancer Genome Atlas (TCGA) tumor tissue samples (cutaneous melanoma n = 367, lung squamous cell carcinoma n = 501, bladder urothelial carcinoma n = 408, breast invasive carcinoma n = 768, colorectal adenocarcinoma n = 257), we demonstrate that the frequent chromosomal losses of the tumor suppressor CDKN2A in melanoma and other tumor entities enhance the susceptibility to IFNγ resistance by concomitant deletion of the JAK2 gene (odds ratio = 223...

Aims Previous studies have suggested that many inflammatory cytokines, including interleukin (IL)-1α, may be associated with lumbar radicular pain after disc herniation. In the present study, we examined how variability of the IL-1α gene affects pain intensity and the pressure pain threshold (PPT) in patients with symptomatic disc herniation. Methods A total of 121 patients with lumbar radicular pain due to disc herniation were recruited from Oslo University Hospital, Norway, and followed up at 6 weeks and 12 months...

BACKGROUND: Nasopharyngeal carcinoma is a rare form of cancer across the world except in certain areas such as Southern China, Hong Kong and Malaysia. NPC is considered a relatively radiosensitive tumor and patients diagnosed at early stages tend to survive longer compared to those with advanced disease. Given that early symptoms of NPC are non-specific and that the nasopharynx is relatively inaccessible, less invasive screening methods such as biomarker screening might be the key to improve NPC survival and management...

Aims Lumbar radicular pain after disc herniation may be associated release of pro-inflammatory cytokines from nucleus pulposus (NP) tissue. In the present study we examined the role of interferon-γ (IFN-γ) and cluster of differentiation 68 (CD68) in the acute phase of this process. Methods First, in an animal model mimicking the clinical situation after disc herniation, the role of IFN-γ on the dorsal horn single cell activity and gene expression close to the nerve roots was studied. Second, in patients with severe lumbar radicular pain due to disc herniation, we examined how two single nucleotide polymorphisms (SNPs; rs2069705 and rs2069718) important for the IFN-γ expression influenced the pain and disability measured by visual analogue scale (VAS) and Oswestry Disability Index (ODI)...

PURPOSE OF REVIEW: Defining predisposition to allergic drug reactions has largely focussed on HLA associations, but other genetic and nongenetic factors are also likely to be involved. RECENT FINDINGS: Polymorphic genetic variants in cytokine genes, including IL-10, and co-signalling pathways, including CTLA4, have been associated with allergic drug reactions, but the effect size is lower than with HLA alleles and most associations have not been replicated. Although TCR specificity seems to be important for CBZ-induced SJS/TEN in South East Asian patients, a distinct repertoire may not play a role in reactions to other drugs...

The cause of atopic dermatitis (AD) is multifactorial and a number of genes including cytokines have been involved. We genotyped 315 subjects for polymorphisms in TNF-α and TNF-β and IL-10 genes. Patients had significantly higher frequency of GA genotype of TNF-α (-308 G/A) than healthy controls. Patients with AD and controls had similar distribution of A and G alleles. Genotype AA was found in 7.11% of controls while completely absent in cases. The frequencies of genotypes GG and AA of TNF-β (+252 A/G) polymorphism were higher whereas the frequency of genotype GA was significantly lower in patients than the controls...

Invariant NKT (iNKT) cells are tissue-resident innate-like T cells critical to the host immune response. We previously identified a 6.6 Mbp region on chromosome 1 as a major regulator of iNKT cell number and function in C57BL/6 and 129X1/SvJ mice. Here, we fine-mapped this locus by assessing the iNKT cell response to alpha-galactosylceramide (αGalCer) in a series of B6.129 congenic lines. This analysis revealed the presence of at least two genetic elements that regulate iNKT cell cytokine production in response to αGalCer...

There is robust evidence of an association between insomnia, anxiety, and depression in adolescence. The aim of this review is to describe and synthesize potential mechanisms underlying this association and explore implications for the design of adolescent behavioral sleep interventions. Specifically, we examine whether insomnia symptoms are a mechanism for the development of internalizing symptoms in adolescence and whether sleep interventions are an effective treatment for both insomnia and internalizing symptoms in adolescence because they target the shared mechanisms underlying these disorders...

Introduction: Isotretinoin, a vitamin A-derived medication, is one of the effective treatments for severe acne. However, in a fraction of patients, this treatment causes significant adverse effects. Leptin is a pro-inflammatory cytokine that plays a role in apoptosis of adipose cells and sebaceous lipid metabolism. Thus, genetic polymorphisms in the leptin ( LEP ) gene may modulate the response to isotretinoin therapy. Here, we explore the contribution of rs7799039 polymorphism of the LEP gene in the adverse effects of the oral isotretinoin therapy among acne patients...

Emerging evidence points to interactions between inflammatory markers and stress reactivity in predicting mental health risk, but underlying mechanisms are not well understood. Macrophage Migration Inhibitory Factor (MIF) is a pleiotropic cytokine involved in inflammatory signaling and Hypothalamus Pituitary Adrenal (HPA) axis stress-response, and has recently been identified as a candidate biomarker for depression and anxiety risk. We examined polymorphic variations of the MIF gene in association with baseline MIF levels, HPA axis reactivity, and self-reported anxiety responses to a social stressor in 74 adolescents, ages 10-14 years...

Influenza A virus (IAV) infection causes severe pulmonary disease characterized by intense leukocyte infiltration. Phosphoinositide-3 kinases (PI3Ks) are central signaling enzymes, involved in cell growth, survival, and migration. Class IB PI3K or phosphatidyl inositol 3 kinase-gamma (PI3Kγ), mainly expressed by leukocytes, is involved in cell migration during inflammation. Here, we investigated the contribution of PI3Kγ for the inflammatory and antiviral responses to IAV. PI3Kγ knockout (KO) mice were highly susceptible to lethality following infection with influenza A/WSN/33 H1N1...
