Neural intracerebral allo- and xenografts in pulmonate gastropods demonstrated a variation in the tolerance of neural xenogeneic grafts that was dependent on the phylogenetic distance between the donor and the host. Like allografts, neural congeneric xenografts (Hp/Haa and H1/Haa) of cerebral ganglia (CG) were tolerated and restored growth in juvenile mesocerebrum-deprived (Haa) snails. However, CG neural xenografts between different genera of stylommatophorans (Achatina fulica/Haa) or between genera of different orders (Lymnaea stagnalis: Basommatophora/Haa: Stylommatophora) revealed an interspecific histoincompatibility. These results, compared with those described by other authors, suggest that gastropods possess mechanisms for the recognition of non-self that depend on the organ considered and the phylogenetic distance separating host and donor. Research should now attempt to identify the factors responsible for graft destruction.
