Identification and functional characterization of CD209 homologous genes in zebrafish.

Innate immune responses play a crucial role in maintaining homeostasis, their initiation closely related to pattern recognition receptors or damage-associated molecules on the surface of innate immune cells. CD209, a pattern recognition receptor on the surface of macrophages or dendritic cells, plays an important role in immune functions. However, the impact of CD209 on innate immune cells such as macrophages or neutrophils remains unclear.
