Expression and Immune Characterization of Major Histocompatibility Complex in Paralichthys olivaceus after Antigen Stimulation.

ABSTRACT: The Major histocompatibility complex (Mhc) is an important molecule for antigen presenting and binds to T cell receptors, activating T lymphocytes and triggering specific immune responses. To investigate the role of MhcII in adaptive immunity, in this study, mhcIIα and mhcIIβ of flounder (Paralichthys olivaceus) were cloned, polyclonal antibodies (Abs) against their extracellular regions were produced, respectively, and their distribution on cells and tissues and expression patterns, which varied by antigen stimulation or pathogen infection, were investigated. The results showed that the open reading frame (ORF) of mhcIIα is 708 bp, including 235 amino acids (aa); and the ORF of mhcIIβ is 741 bp, encoding 246aa. The mhcIIα and mhcIIβ were si
