Adaptive immune systems are present only in vertebrates. How do all the remaining animals withstand continuous attacks of permanently evolving pathogens? Even in the absence of adaptive immunity, every organism must be able to unambiguously distinguish “self” cells from any imaginable “nonself.” Here, we analyzed the function of highly polymorphic genevCRL1, which is expressed in follicle and blood cells ofCiona intestinalis, pointing to possible recognition roles either during fertilization or in immune reactions. By using segregation analysis, we demonstrate thatvCRL1locus is not involved in the control of self-sterility. Interestingly, genetic knockdown ofvCRL1in all tissues or specifically in hemocytes results in a drastic developmental arrest during metamorphosis exactly when blood system formation inCionanormally occurs. Our data demonstrate thatvCRL1gene might be essential for the establishment of a functional blood system inCiona. Presumably, presence of the vCRL1 receptor on the surface of blood cells renders them as self, whereas any cell lacking it is referred to as nonself and will be consequently destroyed. We propose that individual-specific receptorvCRL1might be utilized to facilitate somatic self/nonself discrimination.
