Dietary fatty acids alter the adhesion properties of lymphocytes to extracellular matrix proteins

Abstract

Dietary fats have been shown by many investigators to affect immune responses in vitro and in vivo. However, the exact mechanism(s) by which fats or their metabolic derivatives affect immune function is still unknown. In this report we have investigated whether short-term in vitro exposure to fatty acids alters the adhesion of lymphocytes to extracellular matrix proteins. We found remarkably heterogeneous effects with these agents on lymphocyte adhesion; increases and decreases in adhesion were observed depending upon the fatty acid, cell type and extracellular matrix protein used. Alterations in the adhesion potential of lymphocytes could serve as a mechanism for the reported effects of fatty acids on immune function since lymphocytes are dependent upon rapid and reversible adherence events for most of their effector activities.

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function.
