Cell recognition

Definition

noun

(1) Mutual recognition between cells, usually by specific complementary interaction between their respective surface molecules or membrane glycoproteins

(2) The process in which a cell recognizes or identifies its environment


Supplement

Cell recognition is one of the ways by which cells communicate with one another. It is possible through specific cellular adhesion molecules on the surface of the cell.

Examples are:

  • Integrin (LFA-1) of T cell binding to ICAM of endothelial cell
  • Selectin (L) of lymphocyte binding to addressin (CD34) of endothelial cell


Also called:

  • cellular recognition
  • cell-cell recognition
  • cell-to-cell recognition
