The accelerating pace of U.S. FDA approvals for cell and gene therapies is “great for the field and great news for the patients,” but questions remain over commercialization, with “costs remaining stubbornly high.” That was the glass half-full summary of Tim Hunt, president of the industry group, the Alliance for Regenerative Medicine, reprising progress in 2024, and looking forward to the prospects for further growth and the potential impact of the incoming Trump administration in 2025.
Gene editing strategies, from epigenetic engineering to cell reprogramming and genetic vaccines, are accelerating the development of new therapies that awaken the immune system to treat cancer, as presented last month in Rome at the 31st Annual Congress of the European Society of Gene and Cell Therapy (ESGCT). Some of these advances are taking advantage of the conditions of the tumor microenvironment, where cancer cells coexist with immune cells, microorganisms and blood vessels.
Researchers in the U.K. have succeeded in reverse engineering the defective cryptic splicing that drives amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) to enable precisely targeted delivery of transgenes and therapeutic protein expression in diseased neurons. The technique is compatible with conventional adeno-associated viral vectors that are approved for gene therapy, and can readily be adapted for different transgenes. ALS, FTD and other neurogenerative diseases are underpinned by loss of function of the RNA-binding protein TDP-43 (transactive response DNA-binding protein 43), that normally functions as a key regulator of splicing, protecting the transcriptome from toxic cryptic exons.

New single-step genome editing techniques that enable the insertion, inversion or deletion of long DNA sequences at specified genome positions have been demonstrated in bacteria.

New single-step genome editing techniques that enable the insertion, inversion or deletion of long DNA sequences at specified genome positions have been demonstrated in bacteria. The advance opens the door to the development of programmable methods for rearranging DNA, using recombinase enzymes guided by RNA. The two different approaches to using insertion sequences (IS) – some of the simplest and most compact mobile genetic elements – are described in two papers published in Nature and Nature Communications.
