obsolete increased CD4-positive, alpha beta T cell number true Generally, when immunologists write CD8 positive T cell, what they mean is CD8-positive, alpha-beta T cell (CL:0000625). Similarly, when immunologists write CD4 positive T cell, what they mean is CD4-positive, alpha-beta T cell (CL:0000624). T cells bearing the alpha-beta T cell receptor are the most common in the body, and are the most commonly studied, so much so, that in many published papers, the authors do not even bother to specify (or assume) they are studying alpha-beta T cells and thus omit saying so. This term was determined to be identical to previously entered term MP:0008074. The term label of MP:0008074 has been changed to reflect this. 2014-05-06T00:00:00Z MP:0008074 increased CD4-positive, alpha-beta T lymphocyte number MPheno.ontology reduced number of T cells that expresses an alpha-beta T cell receptor complex and the CD4 coreceptor but not NK cell markers csmith MP:0013016
