Construction of a Vero cell line expression human KREMEN1 for the development of CVA6 vaccines.

ABSTRACT: Coxsackievirus A6 (CVA6) has emerged as a major pathogen causing hand, foot and mouth disease (HFMD) outbreaks worldwide. The CVA6 epidemic poses a new challenge in HFMD control since there is currently no vaccine available against CVA6 infections. The Vero cell line has been widely used in vaccine production, particularly in the preparation of viral vaccines, including poliovirus vaccines and EV71 vaccines. Unfortunately, most CVA6 strains failed to propagate effectively on Vero cells. The expression level of virus-specific receptors on the cell membrane significantly influences viral infection. Here, a Vero cell line with stable over-expressing of KREMEN1 (KRM1), a crucial receptor for CVA6, was constructed using the lentivirus system. The cloned cell line, called Vero-KRM1_#11, could ef
