LECT2 Protects Nile Tilapia (Oreochromis niloticus) Against Streptococcus agalatiae Infection.

ABSTRACT: Leukocyte cell-derived chemotaxin 2 (LECT2) is a multifunctional cytokine that especially plays an important role in innate immune. However, the roles of LECT2 in the immune response of the economically important fish Nile tilapia (Oreochromis niloticus) against bacterial infection remains unclear. In this study, a lect2 gene from Nile tilapia (On-lect2) was identified, and its roles in the fish's immune response against bacterial infection were determined and characterised. On-lect2 contains an open reading frame of 456 bp that encodes a peptide of 151 amino acids, as well as the conservative peptidase M23 domain. On-LECT2 is 62%-84% identical to other fish species and about 50% identical to mammals. The highest transcriptional level of On-lect2 was dete
