This comprehensive review explores the multifaceted role of vitamin C (ascorbic acid) in supporting both innate and adaptive immune responses. Vitamin C enhances epithelial barrier integrity, promotes the oxidant scavenging activity of the skin, and accumulates in phagocytic cells like neutrophils, enhancing chemotaxis, phagocytosis, and microbial killing. It also supports
This study investigated the impact of hormone replacement therapy (HRT) on immune function in post-menopausal women. The findings indicated that HRT modulates immune responses, potentially restoring some aspects of immune function altered by menopause. Specifically, HRT was associated with changes in cytokine production and lymphocyte activity, suggesting a shift towards
This study investigates the effects of [norleucine27]growth hormone-releasing hormone (GHRH) (1-29)-NH2 on immune function in elderly adults. Conducted as a single-blind, randomized, placebo-controlled trial, it involved 19 healthy elderly participants (10 women, 9 men) receiving nightly subcutaneous injections of either placebo or GHRH analog for 16 weeks. The results demonstrated
