MAMMALIAN PHENOTYPE - ANNOTATIONS

The Mouse Adult Gross Anatomy Ontology and Mammalian Phenotype Ontology are downloaded weekly from the Mouse Genome Informatics databases at Jackson Laboratories (ftp://ftp.informatics.jax.org/pub/reports/index.html). For more information about these ontologies, see the MGI Publications Page at http://www.informatics.jax.org/mgihome/other/publications.shtml.
Term:decreased CD8-positive, alpha-beta T cell number

Accession:MP:0008079 term browser browse the term
Definition:reduction in the number of the regulatory subset of T lymphocytes that are involved in MHC class I restricted interactions
Comment: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.
Synonyms:exact_synonym: decreased CD8+ T cell number;   decreased CD8-positive T cell number;   reduced CD8+ T cell number;   reduced CD8-positive T cell number
