Susceptibility of neuroblastoma and glioblastoma cell lines to SARS-CoV-2 infection.

ABSTRACT: Modelling cell infection in-a-dish can represent a useful tool to understand the susceptibility of different cell types towards severe acute respiratory coronavirus-2 (SARS-CoV-2) and to decipher its neurotropism. In this perspective, retinoic acid (RA)-differentiated neuroblastoma cell lines, SH-SY5Y and SK-N-BE(2) and glioblastoma cell lines, U-87 MG and U-373 MG, were infected with a SARS-CoV-2 strain, at various multiplicity-of-infection (MOI). We first demonstrated that the common entry genes - needed for invading epithelial cells - were expressed. RA-differentiation induced an upregulation of ace2 and tmprss2 gene expression while inducing downregulation of ctsb and ctsl. Using in situ hybridization and confocal analysis, SARS-CoV-2 gene S RNA was detected intracellularly at MOI 5.0,
