Summary: The study found that 2-SC can reduce oxidative stress and inflammation in rheumatoid arthritis by inhibiting the NF-kappa B pathway. However, one of the 2-SC also has the ability to suppress the NF-kappa B pathway, further reducing the expression of inflammatory factors. These results suggest that 2-SC may be potential drugs for new therapeutic strategies for rheumatoid arthritis.

Summary: This study found that eugenol can inhibit the proliferation, migration, invasion, angiogenesis, and inflammatory response of fibroblast-like synovial cells from rheumatoid arthritis (RA), and promote apoptosis. The molecular mechanisms of eugenol may be associated with vascular endothelial growth factor (VEGF) and NF-kappaB (NF-kB) signaling pathway.

Summary: This study found that 6-shogaol inhibits proliferation, migration, and invasion, and induces apoptosis in rheumatoid arthritis fibroblast-like synoviocytes (FLSs). It also reduces the production of inflammatory cytokines and matrix metalloproteinases (MMPs). Molecular mechanism analysis revealed that 6-shogaol inhibits the PI3K/AKT/NF-kappa B pathway by activating PPAR-gamma. Treatment with 6-shogaol ameliorated joint destruction in a mouse model of collagen-induced arthritis (CIA). Therefore, 6-shogaol may be a potential natural drug for future rheumatoid arthritis treatments.

Summary: In this study, the effects of insulin receptor peptide-1 on oxidative stress and liver injury were investigated. The results showed that treatment with insulin receptor peptide-1 reduced the extent of oxidative stress, alleviated inflammation and necrosis of liver tissue, improved DNA damage by downregulating the activity of reverse transcriptase, and improved the expression of malondialdehyde, hydrogen peroxide, and superoxide dismutase. Additionally, it was found that insulin receptor peptide-1 improved mitochondrial function by activating the expression of phosphatase and protein kinase. These findings suggest that insulin receptor peptide-1 can protect the liver from injury by inhibiting oxidative stress and improving mitochondrial function.

Summary: This study investigates the effects of PRIMA-1(MET) on apoptosis induction and inhibition of pro-inflammatory cytokines in fibroblast-like synoviocytes (FLSs) in rheumatoid arthritis (RA). The results show that PRIMA-1(MET) induces apoptosis in RA-FLSs, upregulates Noxa expression, and downregulates IL-6, IL-1β, p53, and phospho-IKBa expression. Furthermore, PRIMA-1(MET) treatment suppresses pro-inflammatory cytokine production and inhibits NF-kappa B activity. Therefore, PRIMA-1(MET) could be considered as a new therapeutic strategy for rheumatoid arthritis.

Summary: The study found that 60% of ASD patients showed a significant increase in nighttime melatonin excretion, but the increase was significantly lower compared to controls; 40% of patients did not show a significant increase in nighttime melatonin. ASD patients exhibited higher levels of saliva TNF but not IL-6. Sleep function was correlated with melatonin excretion and TNF levels.

Summary: The study found that captive Rhinella icterica toads exhibit typical diurnal variations of plasma glucocorticoids (CORT) and melatonin (MEL) of nocturnal species. Additionally, there is an interaction between CORT and MEL during immune challenge, with LPS-induced systemic inflammation leading to increased plasma CORT and decreased ocular and plasma MEL.

Summary: Matrix metalloproteinases (MMPs) are enzymes associated with inflammatory diseases and obesity. Adipose tissue serves as an endocrine organ that can produce inflammatory mediators, contributing to tissue inflammation. This study investigates the inflammatory effects of a snake venom metalloproteinase (SVMP) on preadipocytes, highlighting the importance of preadipocytes as targets for metalloproteinases.

Summary: Chronic inflammatory diseases are influenced by causal stimuli and the activation of the immune-pineal axis (IPA) may play a role in determining disease susceptibility. The murine model of collagen-induced arthritis provides insights into the different responses of resistant and susceptible animals. Imbalances in the levels of melatonin and corticosterone, as well as cytokine production, may contribute to the development of rheumatoid arthritis.

Summary: The pineal gland plays a key role in surveillance and defense responses. Melatonin secreted by the pineal gland regulates the rolling and adhesion of leukocytes. Pathogens and pro-inflammatory cytokines inhibit nocturnal melatonin synthesis, leading to leukocyte migration to injured areas. ATP acts as a cotransmitter and enhances melatonin synthesis. The pineal gland responds differently to different doses of ATP and shows structure-dependent effects in the brain.
