In a recent work reported in Science, Zhang et al. untangle dynamic changes arising across aging in multiple cell populations within thirteen organs using single-cell transcriptomics and identify four distinct dynamic waves in which immune cells are the most affected

Ageing of the cardiovascular system is associated with frailty and various life-threatening diseases. As global populations grow older, age-related conditions increasingly determine healthspan and lifespan. The circulatory system not only supplies nutrients and oxygen to all tissues of the human body and removes by-products but also builds the largest interorgan communication network, thereby serving as

Neutrophils are the most abundant leukocytes in the blood, with numbers further increasing with age. Despite their essential role as a primary line of defense, neutrophils can contribute to tissue damage and age-related diseases 1 and a high neutrophil-to-lymphocyte ratio predicts all causes of mortality in the elderly 2–5. However, the precise mechanisms driving enhanced
