Tissue cultured from patients' lymph nodes revealed a new virus—a retrovirus. This type of virus contains RNA that it converts to DNA once it infects human cells. Named human immunodeficiency virus, or HIV, its viral code integrates into the host genome, a safe haven from most drugs, and causes lifelong infection.
We also describe approaches used by different retroviruses to target host chromatin for integration, which informed the development of a preclinical class of HIV-1 IN inhibitors. Unexpectedly, these compounds block the morphological transformation of the immature virus particle, a step in virus replication that is far removed from the catalytic
One of the most common examples of a retrovirus is the human immunodeficiency virus (HIV). Other examples include the human T-cell lymphotropic virus type 1 (HTLV-1). This virus can cause a type of cancer, which is called adult T-cell leukemia. Oncogenes. This is a type of retrovirus that contains oncogenes and is associated with tumor development.
Virus (HIV) Shokouh Makvandi-Nejad, University of Oxford, UK Category: Pathogens and Disease Human immunodeficiency virus (HIV), a member of the retrovirus family, is the causative agent of acquired immunodeficiency syndrome (AIDS). HIV invades various immune cells (e.g., CD4+ T cells and monocytes)
Human immunodeficiency virus (HIV) is a retrovirus known to attack the CD4+ T lymphocytes. Of the two subtypes, HIV-1 and HIV-2, the former is common and prevalent worldwide, and the latter is confined to West Africa and hence less common. In individuals with chronic HIV infection not on treatment with antiretroviral agents, as the CD4+ count drops they are vulnerable to a multitude of
retrovirus: [noun] any of a family (Retroviridae) of single-stranded RNA viruses that produce reverse transcriptase by means of which DNA is produced using their RNA as a template and incorporated into the genome of infected cells, that are often tumorigenic, and that include the lentiviruses (such as the HIVs) and the causative agent of Rous
A subset of T lymphocytes positive for the CD4 antigen2 (also termed T4 antigen), is depleted in AIDS and PGL patients. A retrovirus found in T-cell cultures from these patients3–5 is strongly
