Supplementary information

CD11a also known as ITGAL and LFA-1 alpha chain or integrin alpha L is a protein that functions as an important component of the immune system. It has a molecular mass of approximately 180 kDa. CD11a is expressed predominantly in leukocytes enabling these immune cells to adhere and interact with other cells. This adhesive property is especially critical in the trafficking of leukocytes to sites of inflammation and infection. CD11a pairs with CD18 to form the leukocyte function-associated antigen-1 (LFA-1) complex which plays a significant role in cell signaling and immune responses.
Biological function summary

This protein enables leukocyte adhesion and transendothelial migration which are essential for the immune surveillance process. CD11a is a part of the integrin family known for regulating cell adhesion and interactions with the extracellular matrix. By forming a heterodimer with CD18 it mediates tight adhesion between immune cells and endothelial cells. This interaction aids in the immune response by enhancing the activation and movement of T cells and other leukocytes through the vascular endothelium into tissues.

Pathways

The protein participates in the immune cell trafficking pathway and the integrin signaling pathway. In these pathways CD11a contributes to the modulation of immune responses and cell movement. The interaction of CD11a with intercellular adhesion molecule 1 (ICAM-1) and other proteins within these pathways emphasizes its role in the firm adhesion of leukocytes during inflammation and infection ultimately facilitating leukocyte extravasation and tissue infiltration.

CD11a is highly relevant to autoimmune diseases such as psoriasis and multiple sclerosis. For instance in psoriasis the overactive immune response involves overexpression of integrins including CD11a leading to inflammation. The protein Efalizumab a monoclonal antibody against CD11a has been used in the treatment of psoriasis to reduce leukocyte adhesion and activation. Such relationships highlight CD11a's critical role in both normal immune function and pathological conditions.

Target data

Integrin ITGAL/ITGB2 is a receptor for ICAM1, ICAM2, ICAM3 and ICAM4 (PubMed : 10846180, PubMed : 12526797, PubMed : 1676048, PubMed : 3086451). Integrin ITGAL/ITGB2 is a receptor for F11R (PubMed : 11812992, PubMed : 15528364). Integrin ITGAL/ITGB2 is a receptor for the secreted form of ubiquitin-like protein ISG15; the interaction is mediated by ITGAL (PubMed : 29100055). Involved in a variety of immune phenomena including leukocyte-endothelial cell interaction, cytotoxic T-cell mediated killing, and antibody dependent killing by granulocytes and monocytes. Contributes to natural killer cell cytotoxicity (PubMed : 15356110). Involved in leukocyte adhesion and transmigration of leukocytes including T-cells and neutrophils (PubMed : 11812992). Acts as a platform at the immunological synapse to translate TCR engagement and density of the ITGAL ligand ICAM1 into graded adhesion (PubMed : 38195629). Required for generation of common lymphoid progenitor cells in bone marrow, indicating a role in lymphopoiesis (By similarity). Integrin ITGAL/ITGB2 in association with ICAM3, contributes to apoptotic neutrophil phagocytosis by macrophages (PubMed : 23775590). Integrins ITGAL : ITGB2 functions as a receptor of the neuron-specific adhesion molecule ICAM5 ensuring neuron cell-leukocyte adhesion (PubMed : 10741396). Integrin ITGAL/ITGB2 that functions as a signaling receptor of ICAM2, ensuring leukocyte cell-cell adhesion on resting cells (PubMed : 1676048).
