Immune cells in the brain mediate the link between gut microbiome and amyloid beta deposits

New research from the University of Chicago points to microglia, key immune cells in the brain, as a key mediator in the relationship between the gut microbiome and b-amyloid deposits in male mice in a model of Alzheimer's disease.

Biologists discover how a pathogenic fungus can bypass the immune system of plants

A team of biologists has identified that the pathogenic fungus Verticillium dahliae, responsible for wilt disease in many crops, secretes an 'effector' molecule to target the microbiome of plants to promote infection.

Experts create new software that determines a person’s past infections

Recent research suggested that grouping of pathogen-recognizing proteins on immune T cells might be vital in pinpointing if an individual had an infection in the past.

Scientists test the accuracy of enzymes that copy DNA under weightlessness

Researchers at Queen’s University boarded a modified Falcon 20 aircraft at Ottawa airport on May 22nd, 2019 as part of a scheduled “vomit comet” flight. In this mode of flight, the plane repeatedly climbs in a steep parabola to 8 km, alternating with a freefall descent.

Finding better treatments to eradicate infection caused by H. pylori bacterium

Helicobacter pylori (H. pylori) is one of the most common bacterial infections worldwide, affecting more than 40 % of the population and is one of the causes of digestive symptoms, such as epigastric discomfort, heaviness or bloating of the stomach, or of other more serious diseases, such as the development of gastric and duodenal ulcers, gastric lymphoma or gastric cancer.

Antibodies play a major role in managing gut mycobiota, says study

According to recent research, antibody protection against harmful forms of fungi in the gut might be disrupted in some patients with Crohn’s disease.

Study discovers new species of green microalga in São Paulo

A group led by researchers affiliated with the Phycology Laboratory at the Federal University of São Carlos (UFSCar) in the state of São Paulo, Brazil, have discovered a new species of green microalga in a reservoir located in the northwest of the state.

Research identifies distinct gut bacterial profile highly responsive to IBS dietary therapy

People who respond well to the recommended dietary therapy of restricting intake of fermentable carbs for irritable bowel syndrome, or IBS for short, have an abundance of particular types of bacteria in their gut, reveals research published online in the journal Gut.

Researchers expand understanding of how T cells recognize infections or disease

T cells communicate with other cells in the body in search of infections or diseases. This crosstalk relies on specialized receptors known as T cell receptors that recognize foreign molecular fragments from an infection or cancer that are presented for detection by particular molecules called major histocompatibility complex (MHC) or MHC-like.
