dc.description.abstractThe cultured mouse mast cells that are dependent on spleen-derived factor for their proliferation and maintenance and have been shown to be similar to mucosal mast cells in terms of their T-cell dependence and histochemical staining characteristics. Mast cell heterogeneity has been confirmed by functional characterization of mouse bone marrow-derived mast cells (MBMMC) and mouse peritoneal mast cells (MPMCs). MPMCs released around 30% of histamine when stimulated with compound 48/80 whereas MBMMC were almost unresponsive to the same stimulus. Calcium Ionophore A23187 on the other hand, released histamine in dose-dependent manner from MBMMC. The study was undertaken to investigate the effect of antiallergic drug, disodium cromoglycate (DSCG), a synthetic cromone and quercetin, a plant-derived flavonoid on Ca ionophore A23187 induced hi stamine release from MBMMC. MBMMCs were almost unresponsive to DSCG whereas Calonophore induced histamine release was blocked by Quercetin. The results indicate that response of mast cells at one anatomic site to a given stimulus does not necessarily predict the response of mast cells at a different anatomic location to the same stimulus. It shows functional heterogeneity with in a single species. So, it cannot be assumed that antiallergic compounds stabilizing mast cells in one tissue site or organ will be equally efficacious against mast cells in other sites. en_US
