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:abnormal double-negative T cell morphology
go back to main search page
Accession:MP:0002407 term browser browse the term
Definition:any structural anomaly of the subset of T cells found in the thymus that express neither CD4 nor CD8
Comment:These are precursors to mature T cells; normally, they do not circulate, but are found in the thymus and they have not undergone rearrangement of the alpha and beta T cell receptor genes.
Synonyms:exact_synonym: CD4-CD8- T cell abnormalities;   double-negative T cell abnormalities
