Pipetage des cellules (saines et infectées) de sang de patient infecté par le VIH-1

Pipetting all the cells (healthy and infected) in a blood sample from a patient infected with HIV-1. They have been marked and prepared for the sorter (homogenisation and filtration). It is in this laboratory, the P3 laboratory at the Institute of Human Genetics (IGH), that a marker has been identified that makes it possible to differentiate between dormant or reservoir cells, infected with HIV, and healthy cells. This discovery will make it possible to isolate and analyse these reservoir cells which, by silently hosting the virus, are responsible for its persistence even in patients receiving antiretroviral treatment, whose viral load is undetectable. It offers new therapeutic strategies for targeting infected cells.
