• regulatory T cell morphology trait   VT:0004941   (19)
Definition: Any measurable or observable characteristic related to the shape, structure, color, or pattern 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. [CL:0000815, MP:0004941];
• regulatory T cell quantity     (7)
• CD4-positive, CD25-positive, alpha-beta regulatory T cell morphology trait     (12)




MP:0004941 (abnormal regulatory T cell morphology) is numbered similarly to VT:0004941 but is over in the MP ontology (semantics may or may not be similar).

• Counts are "number of measure mappings" and aren't necessarily the count of distinct measures.
• Terms ending in "_" are terminal (leaf) nodes in the ontology structure.
