Analyzing the Effect of Aging on CD8+ T-Cell Phenotype Using Flow Cytometry.
Shin MS, Kang I
Abstract:
One of the most noticeable changes in T-cell immunity with aging is the expansion of memory CD8+ T cells, with a decline in naïve phenotype T cells that reflects both diminished thymopoiesis and the effects of chronic antigenic stimulation with age. Flow cytometry is a useful tool in evaluating immune cells including the phenotype characteristics of different T-cell subsets. Here, we show flow cytometric methods measuring the different subsets of human CD8+ T cells that change with aging.
