recognition

[rek″og-nish´un]

1. the act of recognizing (seeing something as familiar).

2. the state of being seen as familiar.

3. the interaction of immunologically competent cells with antigen that begins with the binding of the antigen to specific antigen receptors on B and T lymphocytes and results in an immune response directed against the antigen. Called also antigen recognition.
