New Cancer Defense Target Discovered at Mayo Clinic

Buzzline

Researchers at Mayo Clinic have unveiled a novel function of TRAILshort, a protein that inhibits T-cell activity, thereby diminishing immune responses to cancer and infections. The findings, published in the Journal of Clinical Investigation, reveal heightened levels of TRAILshort in various cancers including melanoma, lung, breast, pancreatic, and ovarian as well as Hodgkin lymphoma. In preclinical studies, the inhibition of TRAILshort led to the restoration of T-cell activity and enhanced responses to CAR-T therapy. The team suggests that this protein could eventually serve as a target for therapies related to cancer and immune disorders, although additional research is required to assess its safety and efficacy in patients.

00:00Scientists have discovered a hidden immune, off-switch.

00:03The finding comes from Mayo Clinic researchers.

00:06They identified a protein called trail short.

00:09It can suppress T cells, which normally attack cancer cells.

00:13Researchers found elevated trail short across several types of cancer.

00:18That includes melanoma, lung, breast, pancreatic, and ovarian cancers.

00:25The protein activates another molecule called SHP1.

00:30SHP1 acts like a brake, switching down T cell activity.

00:34The discovery could also affect CAR T therapy.

00:37In preclinical models, blocking trail short restored immune activity.

00:41It helped CAR T cells fight tumors more effectively.

00:44Researchers say trail short could become a new target for cancer immunotherapy.

00:49The protein has also been linked to infections and autoimmune diseases.

00:53But this research is still in the preclinical stage.

00:56More studies are needed before potential treatments can be tested in patients.

01:01Disclosure.
