Researchers at Rockefeller University have identified a signaling loop between breast cancer cells and sensory neurons that promoted tumor metastasis, and showed that in animal models, treatment with the approved anti-nausea medication aprepitant could disrupt that loop.

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.

Last week, the 2024 meeting of the International AIDS Society (IAS) was wrapping up as the 2024 Olympic Games were about to begin. That timing was probably what prompted the use of multiple sports analogies at Thursday’s plenary session on HIV prevention strategies. Given the decades-long attempts at developing an HIV vaccine, Peter Piot, past IAS president and director emeritus and professor at the London School of Hygiene and Tropical Medicine, said in his introduction: “This is clearly a marathon. But marathons also finish.”

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 word “niche” implies a specialized environment. But to Fiona Doetsch, the stem cell niche is anything but. For brain stem cells, “the whole organism is the niche,” Doetsch told the audience at the third plenary session of the International Society for Stem Cell Research (ISSCR) annual meeting in Hamburg this week.

For brain stem cells, “the whole organism is the niche,” Doetsch told the audience at the third plenary session of the International Society for Stem Cell Research (ISSCR) annual meeting in Hamburg this week. It’s a surprising idea at first, given the brain’s protection from many circulating substances via a series of barriers, including the blood-brain barrier and the blood-cerebrospinal fluid barrier.

The big advantage of cell culture to model diseases is its throughput. “You can play the disease over and over again in the dish,” Clive Svendsen told the audience at the International Society of Stem Cell Research (ISSCR) Annual Meeting held in Hamburg last week. That high throughput, however, is not particularly useful if the cell lines themselves do not accurately model the disease. Cancer cell lines are used in many cell culture experiments far beyond cancer for their ability to grow. But they are “highly abnormal,” Bill Skarnes told the audience at an innovation showcase, as well as quite unstable. “I don’t think the [HEK-293] cell line is the same in your lab as it is in the lab next door,” Skarnes said.
