Accession:MP:0004941 term browser browse the term
Definition:any structural anomaly of the specialized subpopulation of T cells that act to suppress activation of the immune system and thus maintain immune system homeostasis and prevent pathological self-reactivity; these may include T cells that express the CD8 transmembrane glycoprotein (CD8-positive T cells), those that express CD4 and CD25 (CD4-positive, CD25-positive regulatory T cells or Tregs) and other T cell types that have suppressor function
Synonyms:exact_synonym: abnormal regulatory T lymphocyte morphology;   abnormal regulatory T-lymphocyte;   abnormal suppressor T cell morphology;   abnormal suppressor T cell morphology/development;   abnormal suppressor T lymphocyte morphology;   suppressor T cell abnormalities
 narrow_synonym: abnormal Treg cell morphology
