Different bacteria use same cell surface molecule to invade tissue and promote infection: Blocking bacteria-molecule interaction might prevent many deadly illnesses

A new study identifies a single molecule as a key entry point used by two types of dangerous bacteria to break through cellular barriers and cause disease. The findings, published March 19 in the journal mBio, suggest that blocking the interaction between the molecule, known as CD40, and bacteria may represent a universal strategy for […]

Cell therapy could replace need for kidney transplants

Wake Forest Institute for Regenerative Medicine (WFIRM) scientists are working on a promising approach for treatment of chronic kidney disease — regeneration of damaged tissues using therapeutic cells. By harnessing the unique properties of human amniotic fluid-derived stem cells, WFIRM scientists have demonstrated that the cells could potentially help recover organ function in a pre-clinical […]

Avocado seed extract shows promise as anti-inflammatory compound

An extract from the seeds of avocados exhibited anti-inflammatory properties in a laboratory study, according to Penn State researchers, and it represents a potential source for novel anti-inflammatory compounds that could be developed as a functional food ingredient or pharmaceuticals. The researchers developed the extract over the last decade as a food colorant and it […]

For infection-fighting cells, a guideline for expanding the troops: Researchers look into the mathematical relationship that describes how T cells expand in response to infection

T cells are like the special ops forces of the immune system, detecting and killing infected cells. When a new threat is detected, the cells ramp up from just a few sentry cells to a full platoon. But how does the immune system make just the right amount of T cells, when the starting populations […]

The secret to bats’ immunity

An international research team led by Duke-NUS Medical School, Singapore, has identified molecular and genetic mechanisms that allow bats to stay healthy while hosting viruses that kill other animals, according to a new study published in the journal Nature Microbiology. Bats live very long and host numerous viruses, such as Ebola virus, Nipah virus, and […]

Antidepressant could stop deadly sepsis, study suggests: Previous FDA approval could fast-track new treatment

An antidepressant drug used to treat obsessive-compulsive disorder could save people from deadly sepsis, new research from the University of Virginia School of Medicine suggests. Sepsis is a significant cause of death around the world. The federal Centers for Disease Control and Infection calls it “the body’s extreme response to an infection.” Essentially, the body’s […]

Study offers promise for preventing necrotizing enterocolitis in preemies: Preventing inflammatory white blood cell infiltration in the intestine decreases development of necrotizing enterocolitis in animal model

Researchers at Stanley Manne Children’s Research Institute at Ann & Robert H. Lurie Children’s Hospital of Chicago, and colleagues, discovered a promising direction toward understanding the development of necrotizing enterocolitis (NEC), a devastating intestinal disease commonly affecting premature infants, in order to treat it. Studying the early cellular events leading to NEC in a mouse […]
