*reads article*

yep CCR5 mutation transplant. Amazing stuff.

On this #WorldAIDSday @cgaebler.bsky.social, Olaf Penack & teams at #CharitéBerlin report the #SecondBerlinPatient cured of #HIV after heterozygous CCR5Δ32 HSCT. The study opens exciting perspectives for immune-based #HIVCure strategies for longterm ART-free viral control and ultimately cure.

brilliant news! 7th person cured of HIV via bone marrow transplant- previously we thought you needed to lose both copies of the CCR5 gene (HIV uses CCR5 to enter cells) and donors with that mutation v rare. This cure achieved with the less rare case of 1 functional copy of CCR5! 🧪
A 7th person with HIV is probably cured after stem cell transplant for leukemia, scientists say
A man in Germany has no detectable HIV in his body after he was treated in 2015. Only six other cases have achieved the milestone since the AIDS epidemic began.

Researchers in #ScienceTranslationalMedicine leverage adeno-associated vectors to deliver the CCR5-blocking HIV drug #leronlimab and show that a single dose elicits leronlimab expression and can partially suppress SHIV in infected macaques for as long as one year. https://scim.ag/493ivwQ

Our paper on the second Berlin patient came out in Nature today and I’m really happy we can share this story on World AIDS Day. I want to thank everyone on the team and all co-authors for their work over the years.

"All four of these patients had undergone stem cell transplants for their blood cancer treatment. Their donors also had the same HIV-resistant mutation that deletes a protein called CCR5, which HIV normally uses to enter the cell."
5th person to be cured of HIV

“Today, researchers announced the Dusseldorf patient still has no detectable virus in his body, even after stopping his HIV medication four years ago.”

CCR5 delta 32
Je lis avec grande attention cet article de Fred qui collecte et compile les cas de rémissions du VIH. Vraiment je découvre, car je ne savais même pas qu’on avait des cas officiels de rémission, et surtout je n’avais pas prêté attention à ce curieux mot de CCR5 delta 32 ou CCR5-Δ32. Je comprends donc que l’ensemble des cas de rémission est lié à une mutation d’un gène d’une protéine de la surface des leucocytes qu’on appelle CCR5. Le VIH via la protéine d’enveloppe virale _gp120_ se fixe d’abord au CD4, présent notamment à la surface des lymphocytes T CD4+, mais aussi de macrophages et de cellules dendritiques. Cette première liaison modifie la conformation de gp120 et permet ensuite sa fixation à un corécepteur de _chimiokine_ : CCR5 pour les virus dits R5-tropes, CXCR4 pour les virus dits X4-tropes, mais certains variants peuvent utiliser l’un ou l’autre. Le schéma ci-dessus illustre cela. On voit le VIH qui avec CD4 et CCR5 arrive à pénétrer dans une cellule. Mais dans le cas de personnes avec cette fameuse mutation CCR5 delta 32, il devient impossible (ou sans doute beaucoup plus difficile) de s’introduire dans la cellule, et donc de _littéralement infecter_ la personne. C’est qui explique que ces _mutants_() soient immunisées contre le VIH, et que dans le cas de don de moëlle ou de cellules souches de ces gens là, on ait pu assister à des rémissions apparentes. Mais donc tout cela modulo le type de virus et la capacité à _choper_ cette mutation… Et ce n’est pas anodin non plus, car cette mutation n’est pas complètement sans effet, elle modifie la capacité à faire face à quelques agents infectieux. Mais j’imagine qu’être immunisé au VIH ou une rémission de sa séropositivité vaut un ou deux rhumes carabinés. Il y a des recherches sur l’origine de cette mutation, car elle est beaucoup plus représentée dans le nord de l’Europe. Et on se demande si ça n’aurait pas par exemple un lien avec des épidémies (de variole) et un avantage de sélection naturelle pour les porteurs du CCR5-Δ32. Mais rien n’est prouvé du tout à ce niveau. L’idée des traitements est bien de reproduire *fonctionnellement* ce que la mutation CCR5-Δ32 produit, et donc de rendre nos CCR5 un chouïa boîteux, afin que les cellules deviennent résistantes au type de VIH qui utilise CCR5. Mais pour le moment, ce ne sont que des pistes de recherche… Je plussoie2

Dies verdeutlicht, dass neben der CCR5-Δ32-Mutation auch weitere Faktoren, wie eine effektive Reduktion des HIV-Reservoirs, zu einer anhaltenden HIV-Remission beitragen können.

Charité Berlin researchers report HIV remission lasting over 6 years in a man who received a stem cell transplant from a donor with only one copy of the CCR5Δ32 mutation.

This suggests full CCR5 resistance is not essential for long-term HIV cure.

A new HIV cure case has just been reported. A patient in Oslo has achieved long-term HIV remission after a stem cell transplant from a sibling donor with a rare genetic mutation (CCR5Δ32/Δ32).
This is now one of only a handful of documented cases worldwide.

I've been teaching my students about the delta-32 CCR5 mutation since...2017? It's a really fascinating story about how some people are naturally immune to HIV because of how specifically it binds to & enters cells. It's great to see the "next steps" in developing this into a treatment possibility!
