A cure for prions?

Whoah. cite>Brainwide silencing of prion protein by AAV-mediated delivery of an engineered compact epigenetic editorScience 28 Jun 2024 Vol 384, Issue 6703

Editor’s summary
Prion diseases are devastating neurodegenerative disorders that are invariably fatal, but removal of the prion protein from neurons can protect against disease progression. Neumann et al. developed a compact epigenetic silencer called CHARM that could efficiently shut off the prion gene throughout the mouse brain when delivered systemically by a viral vector without changing the underlying DNA sequence (see the Perspective by Whittaker and Musunuru). The epigenetic editor can also be programmed to turn itself off after silencing its target, thus limiting potential adverse effects from long-term expression. CHARM represents a therapeutic modality that could be applied to a range of other diseases caused by the toxic buildup of unwanted proteins. —Di Jiang

Holy SHIT. Okay, this needs an "in mice" caveat, but the tactic they took means it's less of a caveat than usual and also HOLY FUCKING SHIT

We will not edit your comments. However, we may delete your comments, or cause them to be hidden behind another link, if we feel they detract from the conversation. Commercial plugs are fine, if they are relevant to the conversation, and if you don't try to pretend to be a consumer. Annoying endorsements will be deleted if you're lucky, if you're not a whole bunch of people smarter and more articulate than you will ridicule you, and we will leave such ridicule in place.
