Study reveals how barrier cells that line the intestines send messages to patrolling T cells

Cells in the gut send secret messages to the immune system. Thanks to new research from La Jolla Institute for Immunology (LJI) scientists, we can finally get a look at what they're saying.

Intranasal COVID-19 vaccine developed from bacterial extracellular vesicle induces robust antibody response in preclinical trials

A team of US-based scientists recently developed a novel vaccine candidate against SARS-CoV-2, the causative pathogen of COVID-19. The vaccine is composed of extracellular vesicles of Salmonella typhimurium incorporated with the spike receptor-binding domain (RBD) of SARS-CoV-2. Upon intranasal administration in hamsters, the vaccine induces strong blood antibody titers and protects against severe COVID-19.

Bioactive packaging can keep strawberries fresh for up to 12 days

Québec produces more strawberries than any other Canadian province. Strawberries are delicate and difficult to keep fresh. In response to this challenge, Monique Lacroix, a professor at at the Institut national de la recherche scientifique, and her team have developed a packaging film that can keep strawberries fresh for up to 12 days.

Salmonella bacteria colonize the gut using intestinal epithelial cells

The immune system's attempt to eliminate Salmonella bacteria from the gastrointestinal (GI) tract instead facilitates colonization of the intestinal tract and fecal shedding, according to National Institutes of Health scientists.

Endocannabinoids in the body can help fight intestinal infections

Endocannabinoids, signaling molecules produced in the body that share features with chemicals found in marijuana, can shut down genes needed for some pathogenic intestinal bacteria to colonize, multiply, and cause disease, new research led by UT Southwestern scientists shows.
