Different steroids co-regulate long-term expansion versus terminal differentiation in primary human erythroid progenitors.

abstract：:In human immunodeficiency virus (HIV)-1 infection, decrease of telomere length is mainly found in CD8(+) T cells and not in CD4(+) T cells. Telomerase, a ribonucleoprotein enzyme that can synthesize telomeric sequence onto chromosomal ends, can compensate for telomere loss. Here, we investigated if telomerase activity...
