Phenotypic Mixing between Murine Oncoviruses and Murine Cytomegalovirus

Morphological and ultrastructural changes induced in corneal epithelial cells by HIV-1 and HHV-6in vitro

“…There is speculation that HIV-1 can enter non CD4-t cells via another type of receptor, for instance, galactocerebroside (galC) usually found on neuron, oligodendrocytes or Scwann cells (32). Some investigators have shown that HIV-1 may also enter such cells by phenotypic mixing when other pathogens are present, for example, herpesvirus or other retroviruses (33)(34).…”

Characterization of a Simian Foamy Virus Isolated from a Spontaneous Primate Lymphoma

“…Cells used for cocultivation of pathologic materials – bat lung (Tb), canine thymus (8155), rat fibroblast (Rat‐1), normal and Kirsten‐sarcoma virus‐transformed rat kidney (NRK and K.NRK, respectively) – originated and were maintained as previously described [33, 35]. The murine sarcoma virus‐transformed non‐producer mink (Mi S + L – ) and mouse cells (KA31) as well as the murine (NIH/3T3 and Balb/3T3) cells employed in focus and plaque assays, and the transformed rat cells (XC) and human lung fibroblasts (7605L) used in the XC assays have all also been recently described [33, 34].…”

“…The murine sarcoma virus-transformed non-producer mink (Mi S+L_) and mouse cells (KA31) as well as the murine (NIH/3T3 and Balb/3T3) cells employed in focus and plaque assays, and the transformed rat cells (XC) and human lung fibroblasts (7605L) used in the XC assays have all also been recently described [33,34], Assay of Viral Infectivity XC and focus assays and measurement of reverse transcriptase activity were all per formed following standard procedures [32,37]. For plaque assay of the virus isolated in these studies, 2 X 10s Rat-1 or 8155 cells were seeded per 50-mm Petri dish and main tained in growth medium at 37 °C overnight.…”

Pseudotyped Vesicular Stomatitis Virus-Severe Acute Respiratory Syndrome-Coronavirus-2 Spike for the Study of Variants, Vaccines, and Therapeutics Against Coronavirus Disease 2019

“…Thus, a temperature-sensitive (ts) mutant of VSV was reported, which was deficient in the synthesis of its G protein at nonpermissive temperatures . Several PVs were supplemented with foreign viral glycoproteins (GPs) using VSV strain ts045, including VSV-Avian sarcoma viruses, VSV-Rous sarcoma virus, VSV-Murine leukemia virus, VSV-Murine oncoviruses and -murine cytomegalovirus, and Rousassociated virus 1 is a VSV-Avian retrovirus (Weiss et al, 1977;Lodish and Weiss, 1979;Schnitzer and Gonczol, 1979;Weiss and Bennett, 1980). Furthermore, an infectious defective interfering (DI) particle was characterized as a VSV strain with faulty replication and amplification of its RNA genome but proper viral packaging (Pattnaik and Wertz, 1990).…”
