Fat-Dissolving Bile Acids may help regulate Gut Immunity and Inflammation

Could bile acids—the fat-dissolving juices churned out by the liver and gallbladder—also play a role in immunity and inflammation? The answer appears to be yes, according to two separate Harvard Medical School studies published in Nature.

The findings of the two studies, both conducted in mice, show that bile acids promote the differentiation and activity of several types of T cells involved in regulating inflammation and linked to intestinal inflammatory conditions. They also reveal that gut microbes are critical for converting bile acids into immune-signaling molecules.

The work suggests possible therapeutic pathways for modulating ...

Hydrogels Control Inflammation to Help Healing

An illustration shows how effective a selection of custom-designed peptide hydrogels are in controlling inflammation. The gels developed at Rice University serve as scaffolds for new tissue and show promise for treating wounds and cancer and for delivering drugs. The hydrogels are designed to dissolve in the body as they are replaced by natural, functional tissue. Illustration by Tania Lopez-Silva

Scientists model how synthetic gels can tune body’s inflammatory response. Hydrogels for healing, synthesized from the molecules up by Rice University bioengineers, are a few steps closer to the clinic.

Rice researchers and collaborators at Texas Heart Institute (THI) have established a baseline set of injectable hydrogels that promise to help heal wounds, deliver drugs and treat cancer...

How Inflammation causes Gastric Cancer

A schematic illustration of the role of Noxo1 and NOX1 in the inflammation-associated gastric tumorigenesis. Helicobacter pylori infection causes chronic gastritis, which further induces expression of Noxo1 through TNF-α/NF-κB inflammatory cytokine pathway. Induction of Noxo1 as well as other NOX1 complex, such as NOX1, Noxa1 and Cyba, leads to activation of NOX1 complex and ROS production. Increased ROS level in the inflamed gastric mucosa results in expansion of SOX2-positive stem cell population, which induces gastritis-associated gastric metaplasia and hyperplasia. This Noxo1-involved inflammatory pathway contributes to gastric tumorigenesis in the H. pylori-infected stomach.

Colon Cancer Growth reduced by Exercise

Could short bursts of high-intensity exercise immediately reduce the growth of colorectal cancer cells?

Exercise may play a role in reducing the growth of colon cancer cells according to new research published in The Journal of Physiology. The study found that after a short session of high intensity interval training (HIIT), growth of colon cancer cells was reduced, and this also increased indicators of inflammation.

For a long time, the focus on exercise has been on the positive changes in the body that occur following a longer period of training. However, these findings suggest that the effects following a single session of HIIT, an exercise regime involving short, high energy bursts are also important...
