A new possible mechanism of human immunodeficiency virus type 1 infection of neural cells.

To study the mechanism by which HIV-1 infects neurons we have used human neuroblastoma cell lines (NB). NB (SK-N-SH and SK-N-MC) were found to be susceptible to productive infection by X4 or R5 HIV-1, as detected by viral load and Ag-p24. To identify the putative receptor, we tested the cell surface expression of previously described receptors such as CD4… (More)
