Propofol can induce acute neuronal apoptosis, neuronal loss or long-term cognitive impairment when exposed in neonatal rodents, but the mechanisms by which propofol induces developmental neurotoxicity are unclear. Recent studies have demonstrated that propofol can increase the TNF-α level in the developing brain, but there is a lack of direct evidence to show whether TNF-α is partially or fully involved in propofol-induced neurotoxicity. The present study shows that propofol exposure in neonatal rats induces an increase of TNF-α in the cerebral spinal fluid, hippocampus and prefrontal cortex (PFC)...

BACKGROUND: Hidradenitis Suppurativa (HS), also known as acne inversa, is a painful, chronic, debilitating, inflammatory skin disease and has shown response to anti-TNF-α therapy. Efficacy and safety of the anti-TNF-α agent, adalimumab, was assessed in a post hoc analysis of women from the first 16 weeks of a phase 2 study of men and women with HS. METHODS: Patients with moderate-to-severe HS in at least 2 body areas, unresponsive or intolerant to oral antibiotics for treatment of their HS, and with no previous anti-TNF-a or systemic non-biologic treatment, were randomized 1:1:1 to 40 mg adalimumab-weekly or every-other-week, or placebo...

IL-22-producing helper T cells (Th22 cells) have been reported to be involved in lgA nephropathy. However, the mechanisms underlying the differentiation and immune regulation of Th22 cells in lgA nephropathy remain unknown. To elucidate the mechanisms by which Th22 cells differentiate and are recruited into the kidney in lgA nephropathy, the distribution of Th22 cells in both the kidney and blood was determined. Additionally, the impacts of proinflammatory cytokines and antigen presentation in the kidney on Th22 cell differentiation were explored...

The inflammatory response is essential for normal cutaneous wound healing. Macrophages, as critical inflammatory cells, coordinate inflammation and angiogenesis phases during wound healing. It has been reported that the transcription factor interferon regulatory factor 8 (IRF8), a member of the IRF family, plays a critical role in the development and function of macrophages and is associated with inflammation. However, the role of IRF8 in cutaneous wound healing and its underlying mechanism remain elusive. Through immunohistochemical (IHC) staining, we showed that IRF8 is involved in the wound repair process in mice and patients...

Alphaviruses among the viruses that cause arthritis, consisting in a public health problem worldwide by causing localized outbreaks, as well as large epidemics in humans. Interestingly, while the Old World alphaviruses are arthritogenic, the New World alphaviruses cause encephalitis. One exception is Mayaro virus (MAYV), which circulates exclusively in South America but causes arthralgia and is phylogenetically related to the Old World alphaviruses. Although MAYV-induced arthritis in humans is well documented, the molecular and cellular factors that contribute to its pathogenesis are completely unknown...

Cystic fibrosis (CF) is a genetic disease due to mutations in the cystic fibrosis transmembrane regulator (CFTR), F508del-CFTR being the most frequent. Lipid raft-like microdomains (LRM) are regions of the plasma membrane that present a high cholesterol content and are insoluble to non-ionic detergents. LRM are essential functional and structural platforms that play an important role in the inflammatory response. CFTR is a known modulator of inflammation in LRM. Here we provide mass spectrometry data on the global impact of CFTR mutation and TNF-a stimulation on the LRM proteome...

The HIV may trigger a process of neuronal loss and axonal degeneration throughout the brain, which is carried on by the immune system releasing of proinflammatory cytokines, so that chronic inflammation associated with dysregulated innate immune response, glial cell dysfunction, and adverse antiretroviral therapy (ART) effect play an important role causing milder HIV-associated neurocognitive disorders or asymptomatic neurocognitive impairment. All patients have been tested for neurocognitive functioning through a comprehensive, five-domain neuropsychological battery performed in the study...

FK-506 (Tacrolimus) is a very commonly used immunomodulatory agent that plays important roles in modulating the calcium-dependent phosphoserine-phosphothreonine protein phosphatase calcineurin and thus inhibits calcineurin-mediated secondary neuronal damage. The biological function of FK-506 in the spinal cord has not been fully elucidated. To clarify the anti-inflammatory action of FK-506 in spinal cord injury (SCI), we performed an acute spinal cord contusion injury model in adult rats and hypoxia-treated primary spinal cord microglia cultures...

Correlations between biochemical and immunological markers of programmed cell death (apoptosis), and the functional state of the thyroid gland (hyperthyroidism, euthyroidism, hypothyroidism) have been investigated in autoimmune thyroiditis (AT) (also known as chronic autoimmune thyroiditis). Annexin V, TRAIL and TNF-a, as well as DNA-hydrolyzing antibodies were used as the main markers. Increased levels of TRAIL were found in the serum of AT patients (hyperthyroidism>hypothyroidism>euthyroidism) compared with healthy individuals...

Dimebon (Dimebolin) is an antihistamine drug which has been used in Russia since 1983. Recently Dimebolin has attracted renewed interest after being shown to have positive effects on persons suffering from Alzheimer's disease. Animal studies have shown that dimebon acts through multiple mechanisms, both blocking the action of neurotoxic beta-amyloid peptides and inhibiting L-type calcium channels, modulating the action of AMPA and NMDA glutamate receptors. Our experiments with cell culture L929 and mice have shown that dimebon may exert its neuroprotective effect by blocking cytotoxic signals induced by proinflammatory cytokines such as TNF-a which are believed to play a central role in Alzheimer's disease...

This paper describes the effects of immune genes genetic variants and mRNA expression on depression's risk, severity, and response to antidepressant treatment, through a systematic review on all papers published between 2000 and 2016. Our results, based largely on case-control studies, suggest that common genetic variants and gene expression pathways are involved in both immune activation and depression. The most replicated and relevant genetic variants include polymorphisms in the genes for interleukin (IL)-1b, IL-6, IL-10, monocyte chemoattractant protein-1 (MCP-1), tumor necrosis factor-alpha (TNF-a), C-reactive protein (CRP) and phospholipase A2 (PLA2)...

A comprehensive cross-platform and cross-assay evaluation using nine technology platforms and four cytokine immunoassays (IL-6, TNFα, IL-17a, IL-2) was performed by comparing assay precision, sensitivity, parallelism and data correlation between platforms. The precision was acceptable for most evaluated assays. In addition to comparing the analytical assay sensitivity using a spiked recombinant analyte in buffer, forty serum samples from both normal controls and multiple sclerosis patients were used to measure the frequency of endogenous analyte detection (FEAD) as a parameter of each assay's ability to detect the endogenous analyte...
