DGAT1 and Zika virus infectious disease: In our study, shRNA-mediated downregulation, but not pharmacological inhibition of DGAT1, strongly reduced ZIKV infection in Huh7 cells, and DGAT1 inhibitor treatment did not prevent ZIKV infection in neural cell lines (Hmc3, 1321N1, and SH-SY5Y) or cerebral organoids, indicating a mechanism independent of DGAT1 activity.
