Abstract:
Integrin LFA-1 plays an important role in leukocyte trafficking to inflammatory sites as well as the interaction of T cells with antigen-presenting cells. Inhibition of the LFA-1:ICAM-1 interactions is a promising therapeutic approach for alleviating inflammation and autoimmune diseases. This chapter describes cell-free assays to study the LFA-1:ICAM-1 interactions. These assays may be used for screening novel LFA-1 antagonists.

Activation of Integrins
In "outside-in signaling," external factors in the extracellular space bind to exposed ligand binding sites on integrins. This causes the inactive protein to undergo a conformational change to become active. Integrins are often clustered on the cell membrane. Repetitive and regularly spaced ligand binding events provide an effective stimulus.
Integrins
Some ECM proteins assemble into a basement membrane to which the remaining components adhere. Proteoglycans typically form the bulk of the ECM while fibrous proteins, like collagen,...
