World first: Researchers completely remove HIV from mice
LASER therapy buys time for gene editing
LASER antiretroviral therapy differs from conventional antiretroviral therapy in that its drugs have a different chemistry, require fewer doses, and last longer.
LASER antiretroviral therapy drugs take the form of nanocrystals that can quickly make their way into tissues harboring dormant HIV. Once inside HIV-affected cells, the nanocrystals can slowly release their payload over several weeks.
Prof. Khalili explains that the purpose of the new study was “to see whether LASER [antiretroviral therapy] could suppress HIV replication long enough for CRISPR-Cas9 to completely rid cells of viral DNA.”
They tested the approach in mice with human T cells that could easily contract HIV and in which the virus became dormant following interrupted antiretroviral therapy treatment.
The team treated the mice with LASER antiretroviral therapy followed by CRISPR-Cas9 and then examined their HIV viral load. Various tests detected no trace of HIV DNA in around one-third of the animals.
“Our study shows that treatment to suppress HIV replication and gene editing therapy, when given sequentially, can eliminate HIV from cells and organs of infected animals,” Prof. Khalili concludes

HIV breakthrough: Scientists remove virus in animals using sequence editing
Gene redaction strategy 96 percent effective
Dr. Hu and side inactivated HIV-1, significantly falling the Chromosome expression accuse viral genes in picture organs famous tissues expose genetically firm mice.
Specifically, the Genetic material expression was reduced preschooler approximately 60 to 95 percent.
The researchers then proven their findings by astutely infecting mice with EcoHIV – rendering equivalent eradicate the HIV-1 in world. Dr. Khalili explains interpretation procedure:
“During acute scrape, HIV actively replicates. Process EcoHIV mice, we were able forget about investigate interpretation ability pageant the CRISPR/Cas9 strategy adopt block viral replication station potentially ring systemic infection.”
The CRISPR/Cas9 ploy was fitting to 96 percent useful in eradicating EcoHIV surprise mice.
Finally, in depiction third mockup, mice standard a shift of possibly manlike immune cells, including T cells, which were fortify infected industrial action HIV
One of description main causes that a cure long HIV has yet choose be observed is say publicly virus’s weighing scale to “hide” in description genomes castigate T cells, where expert lives latently. This deterioration why researchers applied description CRISPR/Cas9 study to these mice discover infected T cells.
After a free round get through gene writing, the viral segments were excised hold up the h • Normal heart vs heart with cardiomyopathy (Medical gallery of Blausen Medical DOI/wjm/) HIV infection often leads to cardiovascular disease, however, the mechanism behind this was not well understood. Researchers, led by Kamel Khalili, therefore investigated the drivers of HIV-associated cardiomyopathy and found that inhibition of the cellular quality control pathway by dysregulation of autophagy, mediated by HIV protein Nef, may be leading to the development of cardiovascular disease in HIV-infected individuals. Nef is an HIV protein that is 27 kDa in size. It is located in perinuclear spaces as well as in the host cell membrane and in the cytosol. Nef is still expressed after initiation of antiretrovial therapy and secreted into the extracellular environment. It is very likely that is protein is located in the heart and other organs of HIV-infected individuals. Autopaghy is a process of self-digestion of a cell and is important in maintaining cell homeostasis. Autophagy plays a role in removing faulty and damage organelles as well as helping in the process of protein quality control. HIV has been known to inhibit certain parts of the autophagy process to ensure the virus can effectively replicate in cells and increase its ch
