Researchers in Japan were able to transfer genes from jellyfish into common fruit flies and discovered that the transferred gene suppressed an age-related intestinal issue in the flies. The findings suggest that studying genes specific to animals with high regenerative capability like jellyfish may uncover new mechanisms for rejuvenating stem cell function and extending the healthy lifespan of unrelated organisms.

Infection or cure? Scientists from Tel Aviv University and the University of Glasgow genetically modified the Toxoplasma gondii to bring a protein inside neurons. The novelty of using a protozoan that can travel from the gut to parasitize the CNS contrasts with the possibility of causing a disease. The scientists are already working on how to avoid it.

A strategy inspired by deficient HIV replication could be used as a treatment to reduce viral load in patients living with HIV and help control the pandemic of the retrovirus. Scientists from the University of California San Francisco want to use HIV against itself by using a parasitic version of the pathogen.

After decades of being woefully under-diagnosed and all but ignored by the biotech and pharma industry, recent advances in understanding its complex etiology could be opening the way to new treatments for endometriosis. Impetus is coming from (modest) increases in funding for basic research, such as the Biden administration’s $200 million for women’s health research and NIH grants under an ‘Advancing cures and therapies and ending endometriosis diagnostic delays’ call announced in March of this year.

Cellular immunotherapy is the Lamine Yamal of cancer therapy. It is easy to forget how young the field is – and that as stunning as it is to watch in action already, it is still reaching its full potential. One aspect of doing so is working in a broader range of tumor types. The field made a giant step toward that goal with last week’s approval of Tecelra (afamitresgene autoleucel, Adaptimmune Therapeutics plc), the first CAR T cell to be approved for treatment of a solid tumor.

To be successful, CAR T-cells need a balance between being effective and overkill. Researchers from the University of Pennsylvania and Vittoria Biotherapeutics Inc. have eliminated the CD5 signaling pathway of their CAR Ts to prevent the immunosuppressive brake effect. In return, this improved their proliferation and antitumor activity in T cell lymphomas.

The 2024 meeting of the International AIDS Society (IAS), which is being held in Munich this week, began with the announcement of another curative bone marrow transplant. The new case brings the total number of patients cured of HIV via a bone marrow transplant up to 7 since “Berlin patient” Timothy Ray Brown became the first such person in 2007.

The industry is looking, with renewed hope, to the “promise” of messenger RNA (mRNA) therapeutics for a wide range of diseases beyond COVID-19, and not only in vaccine form but also for gene and cell therapies.
