lentivirus

lentivirus

 [len´tĭ-vi″rus]
any member of a genus of retroviruses that have long incubation periods and cause chronic, progressive, usually fatal diseases in humans and other animals. Species include the types of human immunodeficiency virus.

len·ti·vi·rus

(len'ti-vī'rŭs),
A genus in the family Retroviridae containing five serogroups that reflect the host with which they are associated. Among the primate lentiviruses are human immunodeficiency viruses types 1 and 2.

lentivirus

/len·ti·vi·rus/ (len´tĭ-vi″rus) any virus of the subfamily Lentivirinae.

Lentivirus

/Len·ti·vi·rus/ (len´tĭ-vi″rus) a genus of retroviruses that cause persistent infection that typically results in chronic, progressive, usually fatal disease; it includes the human immunodeficiency viruses.

lentivirus

(lĕn′tĭ-vī′rəs)
n. pl. lentivi·ruses
Any of a group of retroviruses of the genus Lentivirus that cause diseases with a long latent period and a slow, progressive course. HIV is a lentivirus.

In preclinical studies, lentivirus vectors developed by Cell Genesys, have demonstrated safe, efficient and long-lasting gene transfer into a variety of human cells including both dividing and non-dividing cells such as nerve, liver, muscle and bone marrow stem cells.
We found that GFP expression transduced by lentivirus under control of synapsin developed faster and was more robust.
Despite these limitations, advancements in targeting and the ability of retroviruses such as lentivirus to infect nondividing and dividing cells keep it at the forefront of viral gene therapy delivery systems.
Human immunodeficiency virus type 1 (HIV 1) is assigned to genus Lentivirus, subfamily Orthoretrovirinae, family Retroviridae.

The vector used is based on a debilitated form of a lentivirus, which contains an antisense sequence targeted to the envelope gene.
Indeed, SIV-infected sooty mangabeys may be spared, by their failure to mount significant antiviral immune responses, much of the indirect bystander damage seen in pathogenic primate lentivirus infections that both contributes to accelerated CD4 depletion and compromises host immune regenerative capacity.
On the one hand, it could be argued that since there is no known mechanism by which retroviruses kill host cells and, as some panellists have argued, that the evidence that HIV is a retrovirus belonging to the lentivirus family of RNA viruses is not compelling, it should therefore be concluded that HIV cannot be the primacy cause of Aids.
The lentivirus is especially attractive for gene therapy, according to lead investigator Pierre Charneau, PhD, because when it is used as a vector, it has the ability to transfer DNA into poorly-dividing or nondividing cells, such as nerve cells, blood stem cells, and liver and muscles cells.
This led to the discovery of a defined AIDS-causing lentivirus now called HIV-2.
