Kim Y - S, Wielgosz M, Hargrove P, Kepes S, Gray J, Persons D, Nienhuis A. Transduction of Human Primitive Repopulating Hematopoietic Cells
with Lentiviral Vectors Pseudotyped with Various Envelope Proteins.
In 2003, VIRxSYS began the first clinical trial
with a lentiviral vector.
CD4 + T - cells from patients with HIV - 1 were transduced
with a lentiviral vector containing an antisense sequence against the HIV - 1 envelope.
Not exact matches
Single - cell mouse embryos were infected in vitro
with recombinant
lentiviral vectors to generate transgenic mice carrying the green fluorescent protein (GFP) gene driven by a ubiquitously expressing promoter.
Many times
lentiviral vectors are engineered
with non-native envelopes, a process called pseudotyping.
But what's more, the transplanted cells keep producing a foreign protein slipped inside
with the help of a
lentiviral vector, the kind usually used for gene therapy.
A
lentiviral vector with the same modifier, Fuw - dCas9 - Tet1CD, is available from Rudolf Jaenisch's lab in plasmid form or as ready - to - use lentivirus.
The library consists of a pool of
lentiviral vectors with roughly 73 million semi-random, 30 bp DNA barcodes that are integrated into target cells» genomes upon infection.
Generation of an HIV -1-resistant immune system
with CD34 (+) hematopoietic stem cells transduced
with a triple - combination anti-HIV
lentiviral vector.
Since
lentiviral vectors can deliver a large amount of DNA (~ 8 kb)
with a relatively low immune response, it should come as no surprise that researchers are interested in developing these
vectors for gene therapy.
HEK293T cells were transfected
with the following retroviral or
lentiviral constructs,
with their packaging
vectors indicated in the parentheses, using FuGENE 6 reagent (Promega): pMX - puro - STAT5A * (provided by T. Kitamura, University of Tokyo; pCMV - Gag - Pol and pCMV - VSV - G); pLenti - EF - FH - TAZ - S89A (psPAX2 and pVSV - G); PLKO - NS and shTAZ

Genes associated
with melanoma are overexpressed or silenced
with shRNA constructs in
lentiviral vectors and the lab increasingly uses cDNA and sh (short hairpin) RNA libraries for our experiments.
Entry
vector constructs were recombined into adenoviral (pAd, Invitrogen) or
lentiviral (pCSC - Zeo
with Gateway recombination sites cloned into the multiple cloning site) destination
vectors according to manufacturer's instructions.
Lentivirus was produced by cotransfecting replication incompetent
lentiviral vector with psPAX2 (Addgene, 12260) and pLP / VSV - G (Invitrogen).
