Evidence of Fab fragment gene in an invertebrate: The sea star Asterias rubens

Evidence of Irf4 Gene, Irf2, Irf8 Genes in an Invertebrate: The Sea Star Asterias rubens

IRF4 gene, IRF2 and IRF8 genes have been studied in sea star which is the only invertebrate, to possess these factors, playing a rôle in the immune adaptative immunity of A. rubens.

Evidence of low affinity immunoglobulin epsilon Fc receptor gene in an invertebrate: The sea star Asterias rubens

Kappa genes and complement genes were found in the sea star in the past. Recently, we discovered a “sea star IgKappa gene”. We present now a low affinity Ig epsilon Fc receptor gene when compared to mouse genome, in immunized and non-immunized sea stars to HRP.

The TNFR In Asterias rubens Sea Star: Genomic Studies

The sea star Asterias rubens includes TNFR, in its genome, when compared to mouse one: mouse isoform 2 of TNF AIP3-interacting protein 1, mouse TNF receptor-associated factor 2, mouse TNF receptor-associated factor 3, mouse TNF receptor-associated factor 4, mouse TNF receptor-associated factor 6. Many of these factors are bound to NF Kappa -B genes which have recently been isolated in the Aster...

Cell-Mediated and Humoral Immune Responses in the Sea-Star Asterias Rubens (Echinoderm): Notion of Invertebrate Primitive Antibody

Induced cell proliferation in putative haematopoietic tissues of the sea star, Asterias rubens (L.).

The coelomic fluid of the echinoderm Asterias rubens possesses large populations of circulating coelomocytes. This study aimed to expand the knowledge about the haematopoietic sources of these cells. Injection of the immune-stimulating molecules lipopolysaccharide (LPS) and concanavalin A (ConA) resulted in an increase in coelomocytes. To investigate if these molecules induce cell proliferation...
