+title: Determinants of human versus mosquito cell entry by the Chikungunya virus envelope proteins
+date: 2025-08-26
+author: Jesse Bloom

+
+In a new study led by Xiaohui Ju and [recently posted on bioRxiv](https://doi.org/10.1101/2025.08.25.672233), we measure how mutations the Chikungunya virus envelope proteins affect entry in human vs mosquito cells.
+The results help elucidate how this virus can infect cells from such diverse species, and enable us to create loss-of-tropism mutants that can only efficiently infect cells from one species.
