obsolete abnormal CD8-positive alpha beta T cell number true csmith MP:0008077 abnormal CD8-positive, alpha-beta T lymphocyte number 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:0008077. The term label of MP:0008077 has been changed to reflect this.
