The Complement System in Echinodermata

How great is the Echinodermata adaptative and innate immune system ! We find in it, immune genes like the IGKAPPA GENE with Ig sites( for the adaptative immunity) Complement genes, from C1 to C9 for the innate immune system.... As for complement genes: Cr Receptor gene was found so all the alternate and classical genes, we describe in vertebrates. Furthermore, and for the first time MBL2 MASP1 genes which belongs to the Lectin pathway are shown in an invertebrate SO 3 complement pathways exist in Echinodermata: Alternate one, classical one, lectin one.
