Reply to Shin and Bayry on "An age-related decline of CD62L and vaccine response: A role of microRNA 92a?"

Abstract

Aging of the human body affects the immune system by a decline in the ability to raise a response to challenges such as microbial infections or vaccinations. In the very elderly, the decline in such functions appears to relate to a reduced expression of certain co-stimulatory molecules expressed by T lymphocytes. More recently, attention has been drawn to the adhesion molecule CD62L, where differences in expression and function of this molecule between younger and older individuals are suspected to be a part of immunosenescence in the elderly. © 2014 Landes Bioscience.
