Aside from the antiviral role of BMP6 during HCV infection, and BMP6 and Activin A during HBV and Zika virus infection (Eddowes et al, 2019; Jiyarom et al, 2022), BMP8a was shown to be a positive regulator of antiviral immunity upon RNA virus infection in zebrafish by modulating pattern recognition receptor (PRR) signaling leading to type I interferon (IFN) production (Zhong et al, 2021). The gene discussed is BMP6; the disease is Zika virus infectious disease.
