Neuropathic pain affects patients worldwide. The therapeutic effects of current methods are still poor. This study was performed to investigate the neuro-protective effect of orientin in rats with spinal nerve ligation (SNL). In this study, the paw mechanical withdrawal threshold (PWT) and the paw thermal withdrawal latency (PWL) behavioral assays indicated that orientin alleviated the warm and mechanical allodynia in rats with SNL. The enzyme-linked immunosorbent assay (ELISA) showed that orientin suppressed the levels of pro-inflammatory cytokines interleukin-6 (IL-6), interleukin-1β (IL-1β), and tumor necrosis factor alpha (TNF-α) and increased the levels of anti-inflammatory cytokine interleukin-10 (IL-10)...

Dry Eye Disease (DED) is a very common disorder that can result in severe disability and vision loss. Although the pathogenesis of DED is not fully understood, hyperosmolarity, inflammation, and tear film instability are recognized as hallmarks of DED. Recently, Nucleoside Reverse Transcriptase Inhibitors (NRTIs), a class of medication used to treat HIV, have been shown to inhibit inflammation in a mouse model of retinal atrophy. In this study, we investigated whether Zidovudine (AZT) can inhibit human corneal epithelial cell (HCEC) inflammatory responses under hyperosmotic conditions...

It is widely known that not only the gonadal estradiol (E2) but also hippocampal E2 plays an essential role in memory process. However, the role of hippocampal E2-enhanced memory mechanism during aging is largely unknown. The aim of the present study was to investigate the effect of age on E2 concentration, the expression level of its receptors, and key steroidogenic enzymes in hippocampus. We also investigated the effect of microglia activation on E2 synthesis in hippocampal neurons. The results showed that serum E2 was higher in 19-month-old (aged) rats, which exhibited spatial memory decline in the Morris water maze (MWM) test when compared to the younger rats...

Rheumatoid arthritis (RA) is an autoimmune inflammatory disease, affecting almost 1% of world population. Although the exact cause of RA is not known but the complex interaction between inflammatory mediators like tumour necrosis factor-α (TNF-α), interleukin-1β (IL-1β), cyclooxygenase-2 (COX-2) and nitric oxide (NO) is accountable for cartilage destruction in joints. Gold is used for arthritis treatment since long without knowing its mechanism of action. Hence, the present study was designed to assess antiarthritic activity of nanogold (AuNGs) in collagen-induced arthritic (CIA) rat model by virtue of decreasing inflammatory mediators and oxidative stress...

In the current intensive production system, ruminants are often fed high-grain (HG) diets. However, this feeding pattern often causes rumen metabolic disorders and may further trigger laminitis, the exact mechanism is not clear. This study investigated the effect of HG diet feeding on fermentative and microbial changes in the rumen and on the expression of pro-inflammatory cytokines and matrix metalloproteinases (MMPs) in the lamellar tissue. In all, 12 male goats were fed a hay diet (0% grain; n=6) or an HG diet (56...

Inflammation is an energy-intensive process, and caloric restriction (CR) could provide anti-inflammatory benefits. CR mimetics (CRM), such as the glycolytic inhibitor 2-deoxyglucose (2-DG), mimic the beneficial effects of CR without inducing CR-related physiologic disturbance. This study investigated the potential anti-inflammatory benefits of 2-DG and the underlying mechanisms in mice with lipopolysaccharide (LPS)-induced lethal endotoxemia. The results indicated that pretreatment with 2-DG suppressed LPS-induced elevation of tumor necrosis factor alpha and interleukin 6...

Immunoglobulin A (IgA) nephropathy (IgAN), the most common glomerulonephritis worldwide, is characterized by IgA depositions in the kidney. Deficiency of CD37, a leukocyte-specific tetraspanin, leads to spontaneous development of renal pathology resembling IgAN. However, the underlying molecular mechanism has not been resolved. Here we found that CD37 expression on B cells of patients with IgAN was significantly decreased compared to B cells of healthy donors. Circulating interleukin (IL)-6 levels, but not tumor necrosis factor-α or IL-10, were elevated in Cd37-/- mice compared to wild-type mice after lipopolysaccharide treatment...
