Expression of interleukin 5 by the CD4+CD45R0+ subset of human T cells


Sewell, WA and Valentine, JE and Cooley, MA, Expression of interleukin 5 by the CD4+CD45R0+ subset of human T cells, Growth Factors, 6, (4) pp. 295 - 302. ISSN 0897-7194 (1992) [Refereed Article]


The expression of IL5 by CD4+CD45RA+, CD4+CD45R0+ and CD3+CD8+ subsets of human peripheral blood mononuclear cells was assessed. Interleukin 5 expression was detected by RNA extraction, reverse transcription and polymerase chain reaction. Populations of highly purified cells were obtained by a protocol of sequential plastic adherence, magnetic bead separation and flow cytometric cell sorting. IL5 was clearly expressed in the CD4+CD45R0+ subset from 3 to 48 hr after activation. The CD4+CD45RA+ and CD3+CD8+ subsets expressed very much less IL5. By contrast, IL2 expression was readily detected in all sorted populations. Thus, in activated CD4+ cells, IL5 was predominantly expressed in the CD4+CD45R0+ subset, a pattern of expression corresponding to that reported for a number of other cytokines, and differing from that of IL2.
