obsolete abnormal CD4-positive, alpha beta T cell number true aberrant number of T cells that expresses an alpha-beta T cell receptor complex and the CD4 coreceptor but not NK cell markers MPheno.ontology 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 determed to be identical to previously entered term MP:0008073. The term label of MP:0008073 has been changed to reflect this.
