14+ hour, 11+ min ago   (832+ words) Some proteins that vanished millions of years ago may still have something to teach scientists about fighting modern infections. University of Oregon biologists have reconstructed antimicrobial molecules dating back as far as 160 million years, and laboratory tests showed that some…...

4+ day, 16+ hour ago   (356+ words) An unusual immune signature in lung cancer has led researchers toward a potential therapy involving tumor microbes and MAIT cells. Bacteria living inside lung tumors may be doing more than simply occupying the tumor environment. In preclinical research from the…...

5+ day, 22+ hour ago   (745+ words) A bacterial molecule called gladiolin can disarm invasive Candida albicans and strengthen the effects of a major antifungal drug. The findings were published in Current Biology, and emerged from the Monash Warwick Alliance Programme in Antimicrobial Resistance (AMR), a long-term…...

1+ week, 1+ day ago   (464+ words) A microbial metabolite called 3,4 dihydroxybenzoic acid, derived from dietary fiber, improved antitumor immunity in mice. A compound made by gut bacteria during the breakdown of dietary fiber may offer a way to strengthen cancer immunotherapy. In mouse studies, University of…...

1+ week, 2+ day ago   (678+ words) Newly identified CHL1 fibroblasts may help lung cancers escape immune attack by recruiting regulatory T cells around tumors. A previously unknown population of fibroblasts appears to help lung tumors hide from the immune system by drawing suppressive T cells to the…...
