Scientists in the United States have made a significant breakthrough in understanding the regulation of inflammation in rheumatoid arthritis (RA) through the cholinergic pathway. This pathway is mediated by the neurotransmitter acetylcholine (ACh), which can bind to the alpha7 cholinergic receptor (alpha7R) expressed by nonneuronal cells. Research findings suggest that

Research conducted in the United States has uncovered new data on the potential therapeutic effects of pomegranate polyphenols on androgen-independent prostate cancer. The study, published in the Journal of Nutritional Biochemistry, demonstrated that pomegranate polyphenols can down-regulate the expression of androgen-synthesizing genes in human prostate cancer cells that overexpress the

A recent study from the United States sheds light on the complex functions of the CD8 coreceptor on T cells. Researchers at the University of Chicago found that the CD8 coreceptor has two distinct functions: stabilizing the binding of the T-cell receptor (TCR) to the peptide-MHC complex and localizing p56(

Recent research has shed light on the mechanisms involved in silibinin-induced apoptosis of RT4 cells, having intact p53. The study found that silibinin increased p53 protein level and activated caspase cascade, leading to apoptosis. The researchers also discovered a regulatory loop between p53 and caspase 2, where silibinin-caused p53 activation
