lymphocyte function-associated antigen , LFA (Abkürzung)

Lymphocyte function-associated antigen (LFA) can refer to:

It is a mouse monoclonal antibody directed against the alpha chain of the protein lymphocyte function-associated antigen 1 which is involved in immune reactions.

It increases MHC II and adhesion molecules LFA-1 and LFA-3 (lymphocyte function-associated antigen).

CD58, or lymphocyte function-associated antigen 3 (LFA-3), is a cell adhesion molecule expressed on Antigen Presenting Cells (APC), particularly macrophages.

Efalizumab binds to the CD11a subunit of lymphocyte function-associated antigen 1 and acts as an immunosuppressant by inhibiting lymphocyte activation and cell migration out of blood vessels into tissues.

Integrin, alpha L (antigen CD11A (p180), lymphocyte function-associated antigen 1; alpha polypeptide), also known as ITGAL, is a human gene which functions in the immune system.

Lymphocyte function-associated antigen 1, also known as LFA-1 is found on all T-cells and also on B-cells, macrophages and neutrophils and is involved in recruitment to the site of infection.
