CUMC scientists develop a way to recreate personalized immune mouse

Columbia University Medical Center (CUMC) scientists have developed a way to recreate an individual's immune system in a mouse. The "personalized immune mouse" offers researchers an unprecedented tool for individualized analysis of abnormalities that contribute to type 1 diabetes and other autoimmune diseases, starting at the onset of disease.

Study identifies 190 proteins crucial to the functions of key immune sensors

In a healthy immune system, invading pathogens trigger a cascade of alerts and responses to fight off the infection. Sensors called toll-like receptors, or TLRs, act as one of the first lines of defense. Two of these sensors, known as TLR7 and TLR9, specifically recognize and respond to microbial RNA and DNA, respectively. But what determines how these TLRs get where they need to be and sound the alarm for pathogen infection?

Scientists discover cells that chaperone food antigens in the intestine

With every meal, immune cells in the intestine stand like sentries at a citadel, turning away harmful bacteria but allowing vitamins and nutrients to pass. Now, researchers at Washington University School of Medicine in St. Louis have identified the cells that chaperone food antigens, or proteins, in the intestine so that the immune system doesn't mount an attack.

One in four HIV patients have been sexually abused as a child

One in four HIV patients was found to have been sexually abused as a child, according to a two-year Duke University study of more than 600 HIV patients. Traumatic childhood experiences were also linked to worse health outcomes among these patients, who are aged 20 to 71.

Viewpoints: Sandra fluke on slurs; Shifting the cost of uncompensated care

(D)espite the misinformation being spread, the regulation under discussion has absolutely nothing to do with government funding: It is all about the insurance policies provided by private employers and universities that are financed by individual workers, students and their families -- not taxpayers.

Antibody-based therapies successfully protect monkeys from deadly Ebola and Marburg viruses

Army scientists have demonstrated, for the first time, that antibody-based therapies can successfully protect monkeys from the deadly Ebola and Marburg viruses. In addition, the animals were fully protected even when treatment was administered two days post-infection, an accomplishment unmatched by any experimental therapy for these viruses to date.

Consistent gains in five-year survival for children with acute lymphoblastic leukemia

A study by the Children's Oncology Group (COG) reported that five-year survival for acute lymphoblastic leukemia (ALL, the most common type of pediatric cancer) among children treated through COG clinical trials increased from 83.7 percent during the period 1990-1994 to 90.4 percent in the period 2000-2005.

New study to better understand role of the immune system in stroke

Stroke and other diseases and injuries to the brain are often followed by inflammation, caused by a reaction of the body's immune system. This reaction has been seen as something that must be combated, but perhaps the immune system could in fact help with recovery following a stroke. A major new EU project, led by Lund University in Sweden and the Weizmann Institute in Israel, is going to study this question.

Yoga can improve cognitive functioning and reduce depression in dementia caregivers

For every individual who's a victim of Alzheimer's - some 5.4 million persons in the United States alone - there's a related victim: the caregiver. Spouse, son, daughter, other relative or friend, the loneliness, exhaustion, fear and most of all stress and depression takes a toll.

Modified Citrus Pectin binds and blocks harmful effects of Galectin-3

Galectin-3 sounds like a planet out of "Star Trek," but it can be much more ominous. Recently, distinguished integrative physician Isaac Eliaz, M.D., presented breakthrough research demonstrating that the protein Galectin-3 is an active biomarker for numerous life-threatening diseases. Even more importantly, Dr. Eliaz showed how Modified Citrus Pectin (MCP) binds and blocks Galectin-3 throughout the body.

Scientists at Seattle conference discuss progress, obstacles in fight against HIV/AIDS

"Scientists, stymied for decades by the complexity of the human immunodeficiency virus, are making progress on several fronts in the search for a cure for HIV infections," but "a major stumbling block is the fact that HIV lies low in pools or reservoirs of latent infection that even powerful drugs cannot reach, scientists told the Conference on Retroviruses and Opportunistic Infections, one of the world's largest scientific meetings on HIV/AIDS," in Seattle last week, Reuters reports.
