Abstract

The hemocyte transcriptome was for the first time obtained and analyzed in uninfected Planorbarius corneus snails and snails naturally infected with Bilharziella polonica parthenites (Schistosomatidae). Transcripts encoding all groups of immune factors previously described in other gastropods were found in assemblies. Pathogen recognition molecules were the most diverse group of transcripts encoding immunity factors. Toll-like receptors (TLRs) of 11 types were identified. The TLR set did not differ between infected and uninfected snails. The data expand the knowledge of snail immune responses to trematode invasion and make it possible to consider P. corneus as a new model for studying mollusk immune reactions.
