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. greater number of the regulatory subset of T lymphocytes that are involved in MHC class I restricted interactions increased CD8+ T cell number MPheno.ontology increased alpha-beta T cell number abnormal increased amount
