Cytotoxic activity of invertebrate hemocytes with preliminary findings on the tunicate Ciona intstinalis

摘要: Abstract In invertebrates, cytotoxicity can be an efficient natural defence system. Lysins secreted in the body fluids or act at membrane level of effector cells. Hemocytes appear to responsible for cytotoxic response foreign, broad, specific stimuli. The mechanisms by which lysins are released and function not yet very well characterized. findings about cell mediated contact dependent suggest that multiple must considered. allo‐ xenogeneic reactions specificity have been shown, tunicates, humoral observed. Cytotoxic hemocytes, reactions, involved graft rejections. Some properties tunicate hemocyte examined Ciona intestinalis using erythrocyte targets. reaction is fast, calcium‐dependent, behaves sigmoidally according temperature, reaches a maximum 37° C, depends on contact.
