Not sure if you saw it, but there was a section in the paper about histological graft rejection. They found (in one species of gorgonian) autografts were widely accepted while allografts were rejected and caused severe necrosis. So grafts from the same individual survived, but grafts from a different individual of the same species did not. In addition, there was memory, as subsequent allografts were rejected in a much shorter time than the initial one.JoshMatt said:FWIW, cell-mediated immunity in invertebrates generally refers to phagocytosis or encapsulation of microorganisms. There is little evidence that hemocytes (blood cells) function against viral infection (although a possible mechanism was proposed by Zambon et al (Proc Natl Acad Sci U S A. 2005 May 17; 102(20): 7257–7262.)
Can you point me to any info on this? I'd love to read about it.Many researchers consider RNA interference a primary defensive mechanism that protects invertebrates from viral infection.
