At the International AIDS Conference in Munich, researchers highlighted significant advancements in HIV treatment and potential cures, with a focus on the role of stem cell transplants. A seventh patient has been declared HIV-free after receiving a stem cell transplant, marking a shift in the understanding of CCR5 mutations; this patient had only one copy of the mutation, suggesting broader donor eligibility for future treatments. Previous successful cases primarily involved donors with two copies of the CCR5 delta 32 mutation, which inhibits HIV from entering immune cells. This latest breakthrough indicates that even a single copy of the mutation may be sufficient for long-term remission, potentially expanding treatment options for patients. Experts emphasized the importance of continuing efforts to cure the 39 million individuals currently living with HIV, despite the ongoing challenge of preventing new infections. The stories of those cured serve as powerful symbols of hope in the fight against HIV.
