The Sp185/333 system of genes, messages and proteins are expressed in the coelomocytes of the purple sea urchin, Strongylocentrotus purpuratus, and is an extraordinary example of diversification of a putative innate immune response system in an invertebrate. Reviewed here, is the current understanding of this complex system as illustrated by sequence(More)
A survey for immune genes in the genome for the purple sea urchin has shown that the immune system is complex and sophisticated. By inference, immune responses of all echinoderms maybe similar. The immune system is mediated by several types of coelomocytes that are also useful as sensors of environmental stresses. There are a number of large gene families(More)
This study characterizes the highly variable He185/333 genes, transcripts and proteins in coelomocytes of the sea urchin, Heliocidaris erythrogramma. Originally discovered in the purple sea urchin, Strongylocentrotus purpuratus, the products of this gene family participate in the anti-pathogen defenses of the host animals. Full-length He185/333 genes and(More)
