The role of gill podocytes in the recognition of non-self in the crayfish, procambarus clarkII.

Crayfish chromatography indicates that the gills are the primary organ for removal of foreign substances from the circulation of the crayfish. The epithelial podocytes lining the gill sinuses appear to play a major role in clearance of fluorescently labeled latex beads. For all gill podocytes examined, 25% exibited binding of fluorescent latex beads. In contrast, hemocytes remaining in the gills after chromotography consistently had less than 5% positive cells binding the latex beads. Circulating hemocytes are not required for the clearance process. Circulating eosinophilic granulocytes, however, are able to bind and phagocytize non-self substances in vitro. Eosinophilic granulocytes also migrate into areas of tissue that have been injured. The circulating prohemocytes appear to be the source of these granulocytes. They differentiate into granulocytes during the inflammatory response. Thus, the circulating hemocytes appear to play a secondary function in destruction of non-self, after initial clearance of non-self from the circulation by the gill tissues.
