DEP exposure suppresses function of phagocytic immune cells

A team of researchers, led by Dr. Stephan Schwander, of the University of Medicine and Dentistry of New Jersey - School of Public Health (UMDNJ-SPH), has determined a possible link between exposure to a common component of urban air pollution and a change in the function of important immune cells that protect against the bacteria that cause tuberculosis.

Disruption of key cellular functions produces physiologic and behavioral responses

Two Massachusetts General Hospital (MGH)-based research teams, along with a group from the University of California at San Diego, have discovered that animals have a previously unknown system for detecting and responding to pathogens and toxins. In three papers published in the journals Cell and Cell Host & Microbe, the investigators describe finding evidence that disruptions to the core functions of animal cells trigger immune and detoxification responses, along with behavioral changes.

Flu shots offered to populations at risk at the beginning of season

All Care Inala Medical Centre doctor Michael Ho said flu shots were becoming more popular each year. “Flu seasons tends to begin in late March early April to June,” he said. “More and more people are opting to get vaccinations because they are promoted well within the community.” He added, “It is particularly important for elderly people to be immunized because their immune system is already not at its best…This is also the case for people who have chronic medical conditions like diabetes, severe asthma, or heart disease. With their current condition, if they catch the flu they can end up with a worse outcome.”

Researchers discover a lead on the origin of chronic lymphatic leukaemia

Up until now the causes of the development of chronic lymphatic leukaemia, the most common form of cancer of the blood in Europe, have been unknown. At present a cure is not possible. A research group at the MedUni Vienna led by Christoph Steininger of the University Department of Internal Medicine I has now however discovered a lead on the origin of this disease. Says Steiniger: "This could influence the therapy approach taken in treating chronic lymphatic leukaemia."

CLYD gene serves as crucial negative regulator in pulmonary fibrosis

An international team of researchers led by Georgia State University scientists have found a key component in the pathological process of pulmonary fibrosis, a fatal disease for which there is currently no cure.

New method for direct identification of antigens

The immune system is a vital part of our defenses against pathogens, but it can also attack host tissues, resulting in autoimmune disease. The antigens that induce destructive immune reactions can now be identified directly - without any prior knowledge of their possible structure.

Study shows how biofilms form on implanted devices

Bacteria such as Staphylococcus aureus, the 'superbug' behind MRSA, can be a major problem for patients who have a medical implant, such as a replacement heart valve or pacemaker.

Soon a vaccine that targets 90% of all cancers

Results from the safety trial - on patients with blood cancer - found all had greater immunity to the disease after receiving the vaccine. Three of the seven patients who have completed the treatment are now free of the condition.

Researchers identify mechanism of TRPM2 regulation

Professor Makoto TOMINAGA from National Institute for Physiological Sciences (Okazaki Institute for Integrative Bioscience), National Institutes of Natural Sciences, and his research team member Ms. Makiko KASHIO have identified the mechanism through which TRPM2 is activated by body temperature with hydrogen peroxide (a kind of reactive oxygen species) produced by immune reactions.

First study to demonstrate link between social status and genetic regulation in primates

The ranking of a monkey within her social environment and the stress accompanying that status dramatically alters the expression of nearly 1,000 genes, a new scientific study reports. The research is the first to demonstrate a link between social status and genetic regulation in primates on a genome-wide scale, revealing a strong, plastic link between social environment and biology.

Five significant genetic associations for hypothyroidism found

Using its unique online research platform, 23andMe, a leading personal genetics company, has found five significant genetic associations for hypothyroidism in the largest known genome-wide association study of hypothyroidism conducted to date. The details of the study are now available online in the journal PLoS ONE.

Researchers question wisdom of blocking DP1 in patients prone to cardiovascular disease

Niacin, or vitamin B3, is the one approved drug that elevates "good" cholesterol (high density lipoprotein, HDL) while depressing "bad" cholesterol (low density lipoprotein , LDL), and has thereby attracted much attention from patients and physicians. Niacin keeps fat from breaking down, and so obstructs the availability of LDL building blocks.
