Electrical currents may make body’s cancer-killing cells even better killers
NEWS RELEASE 25-JUL-2024 Peer-Reviewed PublicationTRINITY COLLEGE DUBLIN Scientists have discovered that electrical currents may make Natural Killer (NK) cells – our very own cancer-killing immune cells – even better killers, which could have significant implications for treating some cancers. The scientists found that Tumour Treating Fields (TTF) in the laboratory (which mimic exposure of brain...
Clinical trial: Fecal matter transplant helps half of patients with GI cancers overcome immunotherapy resistance
JULY 25, 2024 by Cell Press Credit: CC0 Public DomainFindings from a small, proof-of-concept clinical trial have suggested that fecal microbiota transplants (FMTs) can boost the effectiveness of immunotherapy in a range of gastrointestinal cancers. In the study, published July 25 in the journal Cell Host & Microbe, six of 13 patients who had previously...
