Role of heat shock protein 90 as an antiviral target for swine enteric coronaviruses.

ABSTRACT: A variety of swine enteric coronaviruses (SECoVs) have emerged and are prevalent in pig populations, including porcine epidemic diarrhea virus (PEDV), transmissible gastroenteritis virus (TGEV), porcine deltacoronavirus (PDCoV), and swine acute diarrhea syndrome (SADS)-CoV, a newly identified bat-origin CoV with zoonotic potential. Unfortunately, available traditional, inactivated and attenuated SECoV vaccines are of limited efficacy against the variants currently circulating in most pig populations. In this study, we evaluated the role of host factor heat shock protein 90 (Hsp90) as an antiviral target against SECoVs, exemplified by SADS-CoV. Pharmacological inhibition of Hsp90 diminished SADS-CoV replication significantly in porcine and human cell lines, and also decreased replication of
