AbstractIn this study, we examined the expression patterns and the functions of the tongue sole Cynoglossus semilaevis CD94, CsCD94. CsCD94 is composed of 209 amino acid residues and shares 43.0-50.2% overall identities with known teleost CD94 sequence. CsCD94 has a C-type lectin-like domain. Expression of CsCD94 occurred in multiple tissues and was upregulated during bacterial infection. Recombinant CsCD94 (rCsCD94) exhibited apparent binding and agglutinating activities against both Gram-positive and Gram-negative bacteria in a Ca2+-dependent manner. Treatment of bacteria with rCsCD94 enhanced phagocytosis of the bacteria by peripheral blood leukocytes. Furthermore, incubation of rCsCD94 with bacteria reduced the survival of the bacteria in vitro. Taken together, these results indicate that rCsCD94 is a key factor in the bactericidal and phagocytic effects of tongue sole, and reveal for the first time an essential role of fish CD94 in antibacterial immunity, thereby adding insight into the function of CD94.
