CCR5 and infection: In order to consolidate the profile observed with replication-competent HIV-1 in terms of restricted expression and proviral reactivation by cell stimulation with allogeneic PHA blasts culture supernatants, these experiments were also conducted after infection of CTR, M1 and M12 MDM with VSV-G pseudotyped virus expressing enhanced Green Fluorescent Protein (eGFP) that bypasses the CD4 and CCR5 requirement for viral entry and establishes a highly efficient single round infection of these cells.
