Inflammation is crucial in the defense against infections but must be tightly controlled to limit detrimental hyperactivation. Our diet influences inflammatory processes and omega-3 polyunsaturated fatty acids (n-3 PUFAs) have known anti-inflammatory effects. The balance of pro- and anti-inflammatory processes is coordinated by macrophages and macroautophagy/autophagy has recently emerged as a cellular process that dampens inflammation. Here we report that the n-3 PUFA docosahexaenoic acid (DHA) transiently induces cytosolic speckles of the autophagic receptor SQSTM1/p62 (sequestosome 1) (described as SQSTM1/p62-bodies) in macrophages...

There is a body of evidence linking inflammation, altered lipid metabolism, and insulin resistance. Our previous research found that insulin sensitivity decreased after a four-week diet high in dairy compared to a control diet and to one high in red meat. Our aim was to determine whether a relationship exists between changes in insulin sensitivity and inflammatory biomarkers, or with lipid species. Fasting Tumor Necrosis Factor alpha (TNF-α), Tumor Necrosis Factor Receptor II (sTNF-RII), C-reactive protein (CRP), and lipids were measured at the end of each diet...

Caffeic acid phenethyl ester (CAPE), extracted from propolis, was evaluated the ameliorative effects on insulin resistance and identified the mechanisms, using noninsulin-dependent diabetes mellitus (NIDDM) model mice and insulin resistance (IR) model cells. After 5-week of CAPE supplementation, insulin sensitivity, hyperlipidemia, and peroxisome proliferator-activated receptor-α (PPAR-α) levels were improved in mice. Pro-inflammatory cytokines in serum and the expressions of tumour necrosis factor- alpha (TNF-α) mRNA in tissues were markedly down-regulated from CAPE-treated mice...

CD200 has been reported to be neuroprotective in neurodegenerative diseases. However, the potential protective effects of CD200 in germinal matrix hemorrhage (GMH) have not been investigated. We examined the anti-inflammatory mechanisms of CD200 after GMH. A total of 167 seven-day-old rat pups were used. The time-dependent effect of GMH on the levels of CD200 and CD200 Receptor 1 (CD200R1) was evaluated by western blot. CD200R1 was localized by immunohistochemistry. The short-term (24 h) and long-term (28 days) outcomes were evaluated after CD200 fusion protein (CD200Fc) treatment by neurobehavioral assessment...

The history of psoriasis treatment has been marked by several milestones. Corticosteroids, cyclosporine, tumor necrosis factor alpha (TNF-α) inhibitors and, more recently, interleukin (IL)-17A inhibitors have revolutionized the treatment of psoriasis, each in its own way and time. The IL-23/IL-17 axis is currently considered to be crucial in the pathogenesis of psoriasis and selective IL-23p19 inhibition may bring several advantages with respect to IL-12/23p40 inhibition, or distal blockade of IL-17A or its receptor...

Microcystin-leucine arginine (MC-LR) causes testicular inflammation and hinders spermatogenesis. However, the molecular mechanisms underlying the immune responses to MC-LR in the testis have not been elucidated in detail. In this study, we show that MC-LR induced immune responses in Sertoli cells (SC), germ cells (GC), and Leydig cells (LC) via activating phosphatidylinositol 3-kinase (PI3K)/AKT/nuclear factor kappa B (NF-κB), resulting in the production of pro-inflammatory cytokines and chemokines including tumor necrosis factor alpha (TNF-α), interleukin-6 (IL-6), monocyte chemoattractant protein-1 (MCP-1), and chemokine (C-X-C motif) ligand 10 (CXCL10)...

In this study, we observed that mice lacking the interleukin 1 receptor (IL1r(-/-)), or deficient in interleukin 1-beta (IL1-β), developed multiple epidermal cysts after chronic ultraviolet B (UVB) exposure. Cysts that developed in IL1r(-/-) mice were characterized by the presence of the hair follicle marker Sox 9, keratins (K10 and K14) and normal melanocyte distribution and retinoid X receptor α (RXR α) expression. The increased incidence of cysts in IL1r(-/-) mice was associated with less skin inflammation as characterized by decreased recruitment of macrophages, and their skin also maintained epidermal barrier function compared to wild-type mice...

INTRODUCTION: Acute ischemic injury leads to severe neuronal loss. One of the key mechanisms responsible for this effect is inflammation, which is characterized by the activation of myeloid cells, including resident microglia and infiltrating monocytes/macrophages. P2X4 receptors (P2X4Rs) present on these immune cells modulate the inflammatory response. For example, excessive release of adenosine triphosphate during acute ischemic stroke triggers stimulation of P2X4Rs, leading to myeloid cell activation and proliferation and further exacerbating post-ischemic inflammation...

Previous studies indicated that cyanidin-3-O-β-glucoside (C3G) as a classical anthocyanin exerted an anti-fibrotic effect in the liver, but its bioavailability was quite low. This study was undertaken to explore the restraining effect of C3G and its metabolite protocatechuic acid (PCA) on the activation of hepatic stellate cells (HSCs). Our data demonstrated that the treatment of a carbon tetrachloride-treated mice model with C3G inhibited liver fibrosis and HSC activation. In vitro, both C3G and PCA preserved the lipid droplets and retinol in primary HSCs, and additionally inhibited the mRNA expression of α-smooth muscle actin and collagen I, but elevated the level of matrix metalloproteinase-2 and liver X receptors...

Secretory tumor necrosis factor-alpha (sTNF-α) is known to mediate activation- induced cell death (AICD). However, the role of tmTNF-α in AICD is still obscure. Here, we demonstrated that tmTNF-α expression significantly increased accompanied with enhanced apoptosis during AICD in Jurkat and primary human T cells. Knockdown or enhancement of tmTNF-α expression in activated T cells suppressed or promoted AICD, respectively. Treatment of activated T cells with exogenous tmTNF-α significantly augmented AICD, indicating that tmTNF-α as an effector molecule mediates AICD...
