Abstract

A novel secretory cell type in the initial segment of the Malpighian tubules of the locusts Schistocerca gregaria and Locusta migratoria is described ultrastructurally and studied by means of immunocytochemical techniques. The cells show abundant rough endoplasmic reticulum with interspersed Golgi zones. The richness of the cell secretory machinery and the presence of apical dense pleomorphic granules suggest a role in secretion of proteinaceous material to the tubule lumen. The surprising finding of ACTH (1-24)-, ~-MSH-, and 7B2-1ike immunoreactivity for this cell is discussed.
