Findings are a major step toward understanding persistent infections that affect people with cystic fibrosis

Led by scientists at UCLA, an international team of researchers has discovered that bacteria have a “memory” that passes sensory knowledge from one generation of cells to the next, all without a central nervous system or any neurons. (more…)

Research Shows Why One Bacterial Infection is So Deadly in Cystic Fibrosis

COLUMBUS, Ohio – Scientists have found why a certain type of bacteria, harmless in healthy people, is so deadly to patients with cystic fibrosis.

The bacterium, Burkholderia cenocepacia, causes a severe and persistent lung infection in patients with CF and is resistant to nearly all known antibiotics. Cystic fibrosis is a chronic disorder characterized by a buildup of mucus in the lungs and other parts of the body, and various types of lung infection are responsible for about 85 percent of deaths in these patients.

EAST LANSING, Mich. — A receptor found on blood platelets whose importance as a potential pharmaceutical target has long been questioned may in fact be fruitful in drug testing, according to new research from Michigan State University chemists.

A team led by Dana Spence of MSU’s Department of Chemistry has revealed a way to isolate and test the receptor known as P2X1. By creating a new, simple method to study it after blood is drawn, the team has unlocked a potential new drug target for many diseases that impact red blood cells, such as diabetes, hypertension and cystic fibrosis.

Researchers at Yale University have developed a novel nanoparticle with promising applications in gene therapy, a type of medical treatment that addresses the root causes of diseases now typically treated for symptoms.

The advance could lead to new therapies for many forms of cancer, including brain tumors, as well as for cystic fibrosis and Huntington’s Disease. (more…)

The Woods Hole Oceanographic Institution (WHOI) has signed a $1.18 million agreement with the Flatley Discovery Lab in Charlestown, Mass., to investigate and supply marine microbial extracts as possible treatments for cystic fibrosis (CF).

The life-shortening respiratory disease has eluded attempts at a cure, although researchers have been successful in some cases at adding years to a person’s lifespan, primarily through treatment with antibiotics. (more…)
