Secretory activity in blowfly salivary glands is activated by the hormone serotonin. We have investigated the distribution and activity of two cation pumps that are possibly involved with transepithelial ion transport, i.e. Na(+)/K(+)-ATPase and vacuolar-type H(+)-ATPase (V-ATPase). By immunofluorescence labelling of secretory cells, Na(+)/K(+)-ATPase was localized on the basolateral plasma membrane and V-ATPase on the highly folded apical membrane. Activities of both ATPases were probed in… CONTINUE READING
