[Permissivity of mouse-man hybrid cell clones to three enteroviruses: poliovirus II, coxsackie B3 and echovirus 11. Role of human chromosome F. 19 (author's transl)].

The permissivity of human cells to enteroviruses is linked to the presence of specific cell receptors. Owing to the chance elimination of human chromosomes, the man-mouse hybrid cells may be permissive or not depending on the genome responsible for synthesis of the receptors, and whether it has been conserved or not. By comparison of the cytopathogenic effects and virus production after inoculation of the viruses Polio II, Echo 11 and Coxsachie B3 to various hybrid strains, we observed an identity of the spectrum of permissivity to these three viruses. The enzyme study revealed a very high correlation between this permissivity and expression by the clones of the human glucose phosphate isomerase enzyme, of which the structural gene was localised on chromosome F 19. These results suggest the presence on this chromosome of a gene or syntenic genes, governing the synthesis of specific cell receptors to the viruses studied.
