Research ArticleOpen accessEvery word in the titleComplement Genes in the Asterids Comparisons with the Echinids (Echinoderma)Michel LeclercThe axial organ of the sea star Asterias rubens (Asterid) is a primitive immune organ. The B-like cells, when stimulated by various antigens, produce antibody substances correlating with ig kappa genes. On the other hand, component complement genes were found. For each component, one or several contigs were analysed. It is said that Asterias forbesi, another sea-star, in earlier results, … …American Journal of Immunology, Vol. 9, Issue 1 · 26 Feb 2013 · 7,472 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleA True &#34Candidate Ig Kappa Gene&#34 in the Sea-Star: Asterias rubens (Echinoderma)Michel Leclerc, Patricia Otten, Magne OsterasThe axial organ of the sea-star Asterias rubens is a primitive immune organ. The B-like cells, when stimulated by various antigens, produce antibody substances correlated with Ig Kappa gene. A candidate Ig kappa gene (IgK chain V-IV region S107B precursor) more convincing in term of genome was shown. …American Journal of Immunology, Vol. 9, Issue 3 · 20 Aug 2013 · 7,222 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleEvidence of Interleukin Genes in the Sea-Star: Asterias rubens (Echinoderma)Michel Leclerc, Patricia OttenThe axial organ of the sea star Asterias rubens is a primitive immune organ the sea star T lymphocytes, when stimulated by various lectins, produce lymphokin-like substances with mitogenic properties as shown in earlier studies; they are correlated with Interleukin genes. …American Journal of Immunology, Vol. 9, Issue 2 · 22 Jun 2013 · 7,280 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsCell-Mediated Immune Responses in the Sea-Star Asterias rubens (Echinoderm)Michel LeclercCell-mediated immune responses occur in sea star system. In Asterias rubens it is said that B sea star lymphocytes and T sea star lymphocytes exist in the axial organ which can be considered as an ancestral lymphoid organ. In the same manner the origin of lymphocytes can be found in Invertebrates such as Echinodermal. …American Journal of Immunology, Vol. 8, Issue 4 · 29 Nov 2012 · 7,250 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsHumoral Immune Responses to Various Antigens in the Asterids: A. gibbosa and A. rubensMichel LeclercImmunizations with various antigens of the sea stars Asterina gibbosa and Asterias rubens produce specific humoral immune reactions which initiate the antibody factor. This antibody factor is correlated with kappa genes and could be composed of 4 kappa chains. It is the first time that such phenomenom was described in an invertebrate. …American Journal of Immunology, Vol. 8, Issue 4 · 15 Feb 2013 · 7,306 accessesView PDF Cite
