Durable reprogramming of human T cells may now be possible thanks to a new technique based on the CRISPRoff and CRISPRon methodology. Researchers from the Arc Institute, Gladstone Institutes, and the University of California San Francisco have stably silenced or activated genes in this type of immune cell without cutting or altering its DNA, making T cells more resistant, active, and effective against tumors.

A technology that combines transcriptomic data and AI enables a novel approach to drug discovery based on the state of cells, how they behave and which genes they express. The Drugreflector model, developed by scientists at Cellarity Inc., learns from gene expression profiles and predicts which compounds could induce beneficial changes in that cellular state to develop a treatment.

Expedition Medicines, which Flagship Pioneering Inc. has incubated for the past three years, came out of stealth mode with a $50 million commitment from Flagship to support Expedition’s platform technology to discover small molecules that covalently bind to their target.

Ventus Therapeutics Inc. has entered into a multi-year collaboration with Genentech Inc., a member of the Roche Group, to discover and optimize novel small-molecule candidates for challenging targets in major disease areas using Ventus’ Resolve drug discovery platform.

Durable reprogramming of human T cells may now be possible thanks to a new technique based on the CRISPRoff and CRISPRon methodology. Researchers from the Arc Institute, Gladstone Institutes, and the University of California San Francisco (UCSF) have stably silenced or activated genes in this type of immune cell without cutting or altering its DNA, making T cells more resistant, active, and effective against tumors.

Judo Bio Inc. has announced preclinical data demonstrating that its megalin-STRIKER oligonucleotide therapeutics achieved robust and sustained, kidney cell-selective gene silencing in rodents and nonhuman primates (NHPs).

In vaccine development, one might think that targeting multiple epitopes increases the likelihood of improving outcomes. However, when several immunogens are administered together, the immune system does not always generate antibodies against all of them. Two parallel studies have overcome this challenge by using multiple simultaneous immunogens against HIV, effectively triggering various types of broadly neutralizing antibody (bnAb) precursors in two different preclinical animal models.

A preclinical study presented at the 32nd Annual Congress of the European Society of Gene and Cell Therapy (ESGCT), held in Seville Oct. 7-10, showed a new epigenetic editing technology that enables durable gene silencing using ELXRs, short for Epigenetic Long-Term X-Repressors. With this approach, scientists at Scribe Therapeutics Inc. successfully inhibited the expression of the PCSK9 gene, a key regulator of cholesterol metabolism, in human cells, mice and nonhuman primates.

Nabla Bio Inc. has established a new multiyear research collaboration with Takeda Pharmaceutical Co. Ltd. to advance AI-driven design of protein therapeutics.

While recent advances in gene therapy have offered unprecedented options for patients with hemophilia, new data presented at the 32nd Annual Congress of the European Society of Gene and Cell Therapy (ESGCT), held in Seville Oct. 7-10, revealed persistent concerns regarding the durability of these treatments and their potential liver toxicity.
