Integrin Beta 2 (CD18)

Target
CD18
Molecular classification
Integrin, Transmembrane protein
01

Overview

Integrin beta 2 (CD18) is a transmembrane protein that serves as the common beta chain for all β2 integrins. It plays a crucial role in leukocyte adhesion, migration, and immune response. Deficiency or dysfunction leads to impaired immune responses such as Leukocyte Adhesion Deficiency type I. Targeting specific interactions involving β₂-integrins has therapeutic potential for modulating inflammatory diseases or sepsis without broadly suppressing immunity.
