Identify the host factors interacting with ZIKV NS4B

To identify the host factors involved in NS4B-induced PD-L1 upregulation, we conducted mass spectrometric analysis to identify potential binding partners of NS4B.为鉴定参与NS4B诱导的程序性死亡配体1（PD-L1）上调过程的宿主因子，我们采用质谱分析（mass spectrometric analysis）技术以鉴定NS4B的潜在结合伴侣。
