Coreceptor AXL Facilitates African Swine Fever Virus Entry via Apoptotic Mimicry.

ABSTRACT: African swine fever (ASF) is an acute and hemorrhagic infectious disease caused by African swine fever virus (ASFV), which is listed as an animal epidemic disease that must be reported by The World Organization for Animal Health and that causes serious economic losses to China and even the whole world. Currently, the entry mechanism of ASFV is not fully understood. Especially in the early stages of virus entry, the host factors required for ASFV entry have not yet been identified and characterized. In this study, we demonstrated that ASFV externalized phosphatidylserine (PS) on the envelope functioned as viral apoptotic mimicry, which interacts with AXL, a tyrosine kinase receptor, to mediate ASFV entry into porcine alveolar macrophages (PAMs). We found that AXL was the most pronounced pho
