The present work was undertaken to study the biochemical pathways involved in terms of role of calcium influx and status of energy metabolism in the activation of mast cells obtained from Mastomys natalensis infected with Brugia malayi when challenged in vitro with a potentially allergenic antigen (60 kDa) of Brugia malayi. It was observed that histamine release from sensitized lung and peritoneal mast cells was associated with intracellular influx of radioactive Ca-2+, thus establishing the role of calcium in histamine release. The process of activation of mast cells by 60 kDA antigen was an energy requiring process as it utilized the energy phosphates in the form of ATP and the cells followed the aerobic respiratory pathway for the generation of energy molecules.
