Herein, the abundance of a selection of 148 transcripts involved in immunosenescence and stress response was compared in total RNA of PBMC of healthy young to middle-age probands (35.0 /- 6.5 year old) and healthy old probands (82.5 /- 6.8 year old). This study provides a list of 16 differentially abundant transcripts species in the healthy old probands. Thus, these changes of abundance can be considered as easily accessible biomarkers of ageing. Some of these differential abundances like [[CD28]], [[CD69]], [[LCK]] (decreased abundance in old subjects), [[CD86]], Cathepsin D, H and S (increased abundance in old subjects) might explain biochemical and cytochemical changes observed at the protein level in the immune system and thus might correspond to regulatory processes affecting the ageing process. Indeed these changes reflect the low-grade pro-inflammatory status observed in old persons and suggest a hypo-responsiveness of T-cells together with an increase in antigen presentation potential. In addition, among the differentially abundant transcripts were transcripts involved in the oxidative stress response [[HMOX1]] and [[HSPA6]] mRNAs were found as more abundant in PBMC from elderly subjects.<br /> |mesh-terms=* Adult<br /> * Aged<br /> * Aged, 80 and over<br /> * Aging<br /> * Antigen Presentation<br /> * Biomarkers<br /> * Gene Expression Profiling<br /> * Humans<br /> * Leukocytes, Mononuclear<br /> * Oligonucleotide Array Sequence Analysis<br /> * Oxidative Stress<br /> * RNA, Messenger<br /> <br /> |full-text-url=https://sci-hub.do/10.1016/j.exger.2009.12.001<br /> }}</div>
