Engineered probiotic bacteria boost immune attack against pancreatic cancer

Cancer immunotherapies have transformed treatment for many cancers, but pancreatic cancer remains especially difficult to treat. One major reason is that pancreatic tumors often create a "cold" tumor microenvironment, where the tumor prevents immune cells from mounting a strong attack.

Time zone changes disrupt vital gut bacteria during travel

A dream holiday, an exotic destination, a long-haul flight, and finally some well-deserved rest. The problem is that many travelers arrive at their destination only to spend the first days of their vacation struggling with fatigue, sleep disturbances, low energy levels, and digestive issues.

Yogurt, prebiotics, and probiotics link to lower colorectal cancer odds in U.S. adults

A national NHANES analysis of 9,405 U.S. adults aged 50 and older found that any yogurt, prebiotic, or probiotic consumption was associated with about 50% lower odds of self-reported colorectal cancer. Because the study was cross-sectional, it cannot prove causation but supports further research into microbiota-targeted dietary strategies.

Microbiome science merges with oncology for better cancer treatments

Cancer remains notoriously difficult to treat, partly because tumors co‑opt their surrounding environment, including the resident microbiota, to evade immune surveillance and resist conventional therapies.

Probiotic metabolite found to suppress melanoma tumor growth in mice

Immune checkpoint inhibitors like anti-PD-1 have transformed melanoma treatment, yet more than half of patients fail to respond or eventually develop resistance.

Scientists find link between bacterium in the gut ecosystem and lupus

Scientists at UT Health San Antonio, the academic health center of The University of Texas at San Antonio, found a link between a bacterium in the gut microbiome, or ecosystem, and lupus, which could lead to more effective treatment of the disease, in a study published in Nature Communications.

Computer models could design more effective probiotic supplements

Probiotic supplements found in drugstores nationwide contain an assortment of microbes sold for specific health purposes despite limited understanding of the microbes' connections to their marketed use, new University of Virginia School of Medicine research reveals.

Surface acids found crucial for bacterial shape and growth

Researchers have discovered how acids on the surface of bacteria give these microscopic organisms their characteristic "rod" shape-by keeping an enzyme at bay that would otherwise turn the cylindrical cells into shape-shifting blobs.

Can supplements slow Parkinson’s disease? Review reveals where the evidence stands

Dietary supplements are widely used by people with Parkinson’s disease, but this review finds that none have yet been proven to slow disease progression. Biotics, nicotinamide riboside, and omega-3 fatty acids combined with vitamin E show the most promise, but larger, longer, and better-designed trials are needed.
