Sulfated Polysaccharide-Mediated Sponge Cell Aggregation: The Clue to Invertebrate Self/Nonself-Reche first metazoans. The success of multicellularity demanded an ability to recognize self from nonself. It has been argued that this is achieved by a specific recognition of self (Coombe .. 1984a). This article examines a simple invertebrate cell adhesion system, sponge cell reaggregation, for clues

Historecognition and Immunocompetence in Selected Marine Invertebrates,ge of coming into contact with allogeneic and xenogeneic tissues. All invertebrate phyla examined demonstrate some degree of specific nonself reactions. Some sponges, scleractinian corals, gorgonians, echinoderms, and tunicates have demonstrated the existence of an alloimmune system by fulfilling th

In the vertebrate immune system detection of nonself antigens appears to be the primary mechanism by which self and nonself are distinguished. The mechanisms that distinguish self from nonself in invertebrate historecognition syste

Gysèle Van de Vyvervelopment. Farmer-herder conflicts have resulted in attacks and reprisals. While the farmers are striving to safeguard their lands as violence intensifies, the herders are turning to violent tactics to defend their animals while grazing. The paper is qualitative relying on secondary sources of data.
