Sažetak
Sponges are filter feeders that are exposed to large amounts of bacteria present in their surrounding aqueous milieu. The characteristic cell wall component of gram-positive bacteria, peptidoglycan (PPG), was used as a model molecule to study the responsiveness of cells from the marine demosponge Suberites domuncula toward gram-positive bacteria. The sponge lysozyme, which hydrolyzes PPG, was isolated from the living sponge ; in addition its gene was cloned (SDLYS) and expressed in Escherichia coli. Antibodies were raised against the recombinant protein to demonstrate that in the Western blot both molecules give the same signal. In situ hybridization with SDLYS as a probe showed that cells in the mesohyl, the gray cells, strongly react with SDLYS. Subsequent immunofluorescence studies with antibodies raised against lysozyme revealed that only bacteria react with anti-lysozyme and only those that are scattered within the mesohyl of the tissue. An adaptor gene (AdaPTin-1) was isolated from the same sponge species that encodes a putative protein involved in endosome formation. Based on its differential expression we conclude that sponge cells react to PPG with a rapid activation of endocytosis, followed by the release of lysozyme
