Recombinant viruses were produced in 293T cells using a transient two-plasmid system consisting of a retroviral
vector and a helper plasmid (10;14).
Correctional staff and inmates should be educated about the consequences of unprotected sex and the signs and symptoms of acute retroviral
Pascal Gagneux of the University of California, San Diego and his colleagues then proposed that this genomic feature was a reflection of an HIV-like retroviral
epidemic among ancestral chimps nearly 3 million years ago that left only a few to pass on rare resistance genes.
We began work on this project to do the molecular cloning by manipulating the CD4 gene and putting it into retroviral
vectors and then making the virus," Dr.
particles pseudotyped with SARS-CoV S were made by cotransfection of an S-expressing plasmid, pCAGGS-S, with plasmids encoding MLV or HIV gag-pol and GFP vector genome in 293T cells.
Reasons for this retroviral
activation in some instances of schizophrenia remain unknown, Yolken says.
A second class of endogenous avian retroviral
genome (EAV), discovered in 1985 (10), is present in all breeds of chicken and cannot be eliminated.
Foster City, CA) and Whitehead Institute for Biomedical Research (Cambridge, MA) have patented retroviral
vectors which include an insertion site for genes of interest and are capable of expressing high levels of the protein derived from the genes of interest in a wide variety of transfected cell types.
Throughout the 1970s and 1980s, notes Erik Larsson of the Uppsala University in Sweden, investigators continued to gather evidence that the placenta is a hot spot for retroviral
In a specific embodiment, the vector particles are retronectinimmobilized or ultracentrifugation-concentrated retroviral
vector particles pseudotyped with the feline endogenous retrovirus (RD114) envelope protein .
His group, however, has now shown that the HERV-K protein, called c-orf, can indeed bind retroviral
genes and ferry them out of the nucleus.
