Figure 5. HERV-K_CON Tropism.

(A) Human, squirrel monkey, feline, hamster, or murine cells were infected with VSV-G pseudotyped HERV-K_CON particles. Two days postinfection, GFP⁺ foci were quantified microscopically, and titers are expressed as number of infectious units (i.u.) per milliliter of virus-containing supernatant applied.

(B) Human, squirrel monkey, feline, or murine cells were infected with HERV-K_CON Env pseudotyped HIV-1 particles as in (A). Two days postinfection, GFP-positive foci were quantified.

All data are representative of at least three experiments.
