Invertebrate innate immunity transcript family
The immune response of the purple sea urchin appears to be more complex than previously believed in that it uses immune-related gene families homologous to vertebrate Toll-like and NOD/NALP-like receptor families as well as C-type lectins and a rudimentary complement system. In addition, the species also produces this unusual family of mRNAs, also known as 185/333, which is strongly upregulated in response to pathogen challenge.
