By Pooja Toshniwal PahariaFeb 21 2023Reviewed by Danielle Ellis, B.Sc. In a recent study published in Cell, researchers reported the circulation of a novel Middle East respiratory syndrome -like coronavirus among Malayan pangolins, Manis javanica HKU4-associated CoV .
About the study In the present study, researchers explored pangolins as reservoirs or susceptible host species for zoonotic bat CoV transmission. To investigate MjHKU4r-CoV prevalence among pangolins, MjHKU4-CoV-1 nucleocapsid protein-based luciferase immunoprecipitation system assays were performed. Further, viral particles were examined by transmission electron microscopy, and immunofluorescence analysis was performed using human colorectal adenocarcinoma cells for NP staining.

Download a free copy A novel MERS-like coronavirus MjHKU4r-CoV, phylogenetically associated with bat HKU4- CoV was identified among Malayan pangolins. The isolated MjHKU4r-CoV-1 virus Caco-2 cells used hDPP4 and cellular proteases for cell entry, and the binding was enhanced by a furin cleavage site absent in known bat HKU4r-CoVs.
