Molecular cloning, pathologically-correlated expression and functional characterization of the colony- stimulating factor 1 receptor （CSF-1R） gene from a teleost, Plecoglossus altivelis

Colony-stimulating factor 1 receptor （CSF-1R） is an important regulator of monocytes/macrophages （MO/MФ）. Although several CSF-1R genes have been identified in teleosts, the precise role of CSF- 1R in ayu （Plecoglossus altivelis） remains unclear. In this study, we characterized the CSF-1R homologue...

Description
Summary:Colony-stimulating factor 1 receptor （CSF-1R） is an important regulator of monocytes/macrophages （MO/MФ）. Although several CSF-1R genes have been identified in teleosts, the precise role of CSF- 1R in ayu （Plecoglossus altivelis） remains unclear. In this study, we characterized the CSF-1R homologue from P. altivelis, and named it PaCSF-1R. Multiple sequence alignment and phylogenetic tree analysis showed that PaCSF-1R was most closely related to that of Japanese ricefish （Oryzias latipes）. Tissue distribution and expression analysis showed that the PaCSF-1R transcript was mainly expressed in the head kidney-derived MO/MФ, spleen, and head kidney, and its expression was significantly altered in various tissues upon Vibrio anguillarum infection. After PaCSF-1R neutralization for 48 h, the phagocytic activity of MO/MФ was significantly decreased, suggesting that PaCSF-1R plays a role in regulating the phagocytic function of ayu MO/M（P.
