White Blood Cells
A study published in the Nature journal Aging and Mechanisms of Disease has shown that supplementation with nicotinamide riboside (NR) substantially improves the immune systems of older mice due to its effects on stem cell fate. However, the benefits do not persist after NR is removed. The destiny of blood cells As the researchers explain,...
The human thymus
Publishing in Nature Communications' Cell Death Discovery, a team of Chinese researchers has discovered a reason for thymic involution, the age-related decline of the thymus. Adaptive Immune SystemThe adaptive immune system is a complex mechanism protects us from threats, including viruses and cancer. T cells and B cells are the backbone of this system.Read More...
Clock
Epigenetic clocks have become a mainstay of longevity research over the past few years, with new clocks regularly being established for different species and tissues as well as promising research that uses and builds on these clocks. An international research team has recently created a different kind of clock, an inflammatory aging clock that predicts...
Elderly Person Coughing
Researchers have used a big data approach to disentangle cellular and physiological changes that are specific to COVID-19 from those caused by aging [1]. Identifying these improves our understanding of the disease and may help explain why COVID-19 has a more severe effect on older people. A tangled skein The enormous impact of COVID-19 around...
Respiratory tract infection
A new study published in The Lancet shows the results of Phase 2a and Phase 3 clinical trials for the effectiveness of mTOR inhibition on bolstering the aging immune system against respiratory illnesses. Immunosenescence increases disease risk As we grow older, our immune systems become increasingly dysfunctional and less able to defend us from the...
The immune system as a whole can be broadly separated into two main branches: the innate immune response and the adaptive immune response. The innate immune response is performed by a system that is always present across the body, while the adaptive immune response appears only in response to an infection and is always specific...
