Effects of congenital asplenia on inflammatory response in zebrafish larvae. (A) The expression of inflammatory response–related genes after pathogenic A. hydrophila infection in zebrafish larvae. (B) The expression of inflammatory response–related genes after LPS exposure. (C, D) The expression of Il1β, Il6, and Tnfα proteins after A. hydrophila challenge and LPS by ELISA. (E) A high aggregation of apoptotic cells was observed in the trunk of congenitally asplenic zebrafish by TUNEL assay. The white arrowhead indicates TUNEL-positive cells. Different letters (a, b, c, etc.) indicate significant differences (p < .05).
