While antiretroviral therapy (ART) has slowed the progression of HIV among patients, gene therapy through stem cell research gave resistance to HIV. One method of genetic modification is through the manipulation of hematopoietic stem cells, which replaces HIV genes with engineered particles that attach to chromosomes. Peptides are formed that ...
The physicians found a bone marrow donor with a CCR5-Δ32 mutation in both genomic copies of a gene encoding a cell-surface chemokine receptor called CCR5. Because "most of HIV strains" use the CCR5 receptor to enter a host cell, the mutation confers resistance to HIV infection. [3] [4] The patient himself was heterozygous for CCR5-Δ32.

As of April 2013, two primary approaches are being pursued in the search for a HIV cure: The first is gene therapy that aims to develop a HIV-resistant immune system for patients, and the second is being led by Danish scientists, who are conducting clinical trials to strip the HIV from human DNA and have it destroyed permanently by the immune ...
Since antiretroviral therapy requires a lifelong treatment regimen, research to find more permanent cures for HIV infection is currently underway. [1] It is possible to synthesize zinc finger nucleotides with zinc finger components that selectively (almost selectively) bind to specific portions of DNA.
Timothy Ray Brown (March 11, 1966 [1] – September 29, 2020) was an American considered to be the first person cured of HIV/AIDS. [2] [3] Brown was called "The Berlin Patient" at the 2008 Conference on Retroviruses and Opportunistic Infections, where his cure was first announced, in order to preserve his anonymity. He chose to come forward in ...
Scientists use the lentivirus' mechanisms of infection to achieve a desired outcome to gene therapy. Lentiviral vectors in gene therapy have been pioneered by Luigi Naldini. [3] [4] Structure of a virion of HIV, a type of lentivirus. A membrane with protruding glycoproteins surrounds a capsid containing enzymes and the viral RNA genome.
He is involved in ongoing work with David DiGiusto and others to develop disease-resistant immune systems by transplanting gene-modified HIV-1-resistant stem and progenitor cells. [27] With John Zaia and others, Rossi has worked on Lentiviral vectors for delivering RNA-based gene therapy.
