The document summarizes research characterizing the toll-interacting protein (TOLLIP) gene in the black abalone (Haliotis cracherodii). The researcher obtained partial TOLLIP sequence information for black abalone and identified other toll-like receptor genes. Quantitative PCR analysis found no significant difference in TOLLIP expression levels between control and bacterium-exposed black abalone digestive gland and gill tissues. Future work will further explore the toll-like receptor pathway and compare laboratory results to field data.
