Constitutive expression and alternative splicing of the exons encoding SCRs in Sp152, the sea urchin homologue of complement factor B. Implications on the evolution of the Bf/C2 gene family
The purple sea urchin, Strongylocentrotus purpuratus, possesses a non-adaptive immune system including elements homologous to C3 and factor B (Bf) of the vertebrate complement system. SpBf is composed of motifs t...

Diversity of the penaeidin antimicrobial peptides in two shrimp species
Penaeidins, a unique family of antimicrobial peptides (AMPs) with both proline and cysteine-rich domains, were initially identified in the hemolymph of the Pacific white shrimp, Litopenaeus vannamei. Described h...

Expression of SpC3, the sea urchin complement component, in response to lipopolysaccharide
The homologue of the vertebrate complement component C3 that is expressed in the coelomocytes of the purple sea urchin, Strongylocentrotus purpuratus, designated SpC3, was investigated for changes in response to...

SpC3, the complement homologue from the purple sea urchin, Strongylocentrotus purpuratus, is expressed in two subpopulations of the phagocytic coelomocytes
The lower deuterostomes, including the echinoderms, possess an innate immune system that includes a subsystem with similarities to the vertebrate complement system. A homologue of the central component of thi...
