Research has shown that experimental activation of SIRT1 through NAD+ supplementation or caloric restriction can extend lifespan in model organisms by 15-30%, while SIRT1 knockout animals show accelerated aging phenotypes and reduced stress resistance
These metabolic abnormalities not only interfere with the proliferation, differentiation, and maturation of spermatogonia but also further affect sperm quality and quantity through epigenetic modifications, oxidative stress, and apoptosis [37, 101, 160, 238]
Its naturally produced by the liver and plays a crucial role in the body, from supporting immune function to detoxifying cells
NF-B activated microglia, innate immune cells in the central nervous system, can accelerate the tau seeding and propagation of tau pathology, and inactivation of this transcription factor can lead to a slow down of this propagation demonstrated in the mice model (Wang et al., 2022)
