Abstract

Mast cells play an important role in a variety of inflammatory diseases, particularly asthma and atopy. Peroxisome proliferator-activated receptor gamma (PPARγ) is a member of the large nuclear hormone receptor transcription factor superfamily, and has been recently implicated in the anti-inflammatory response. To investigate a possible role for PPARγ in human mast cells, we studied the effects of a PPARγ ligand, rosiglitazone (RG), on stem cell factor (SCF)-induced migration and fibronectin-induced adhesion in human mast cell-1(HMC-1) cells. It was found that HMC-1 cells expressed PPARγ mRNA. RG inhibited SCF-induced HMC-1 cell migration and fibronectin-induced HMC-1 cell adhesion, the selective PPARγ antagonist GW9662 prevented the inhibitory effect of RG on HMC-1 cells. In conclusion, RG inhibits the migration and adhesion of HMC-1 cells by a PPARγ-dependent mechanism.

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.

Biophysics of Adhesion

Alterations in cell adhesion can disrupt important cellular processes and lead to a variety of diseases, including cancer and arthritis. It is also essential for infectious organisms, such as bacteria or viruses, to cause diseases. Understanding the biophysics of cell adhesion can help understand these diseases.
