Vitamin D deficiency can leave people less able to fight HIV-1 infection

Vitamin D plays an important part in the human immune response and deficiency can leave individuals less able to fight infections like HIV-1. Now an international team of researchers has found that high-dose vitamin D supplementation can reverse the deficiency and also improve immune response.

Study highlights discovery of genetic variants linked to mucinous ovarian carcinomas

New research by an international team including Keck Medicine of USC scientists is bringing the origins of ovarian cancer into sharper focus.

Modifying small white blood cells may help treat immune disorders

Modifying the small white blood cells that protect against disease might help treat immune disorders, according to a study published in Cellular and Molecular Gastroenterology and Hepatology, the basic science journal of the American Gastroenterological Association.

Researchers uncover new mechanism that innate immune system uses to curb viral infections

An innovative mechanism that the innate immune system uses to control viral infections has been uncovered by researchers at the University Medical Centers in Mainz and Freiburg. Central to this is the discovery that two different but related elements of the immune system can act together in concert to fight, for example, rotavirus infections.

Scientists report that mouse with weak bones appears to have strong metabolism

One mouse with weak bones appears to have a strong metabolism, even on a high-fat diet, scientists report. While weaker bones are clearly not a good thing, scientists suspect that, somewhere in the conversation between the genetically engineered mouse's skeleton and the rest of its body, there may be an answer that helps obese individuals avoid some of the worst ravages of this health epidemic.

Helmholtz Zentrum München scientists identify how Epstein-Barr virus conceals in human cells

Scientists at Helmholtz Zentrum München have now discovered how Epstein-Barr virus (EBV) conceals itself in human cells. A main culprit for its bad visibility by the immune system is the viral protein LMP2A. As published in the scientific journal PLOS Pathogens, the protein helps EBV-infected cells hide from T cells. This camouflage through the LMP2A protein may play a major role in the causation of cancer by EBV.

New evidence suggests that biodiversity limits disease outbreaks among humans, wildlife

With infectious diseases increasing worldwide, the need to understand how and why disease outbreaks occur is becoming increasingly important. Looking for answers, a team of University of South Florida biologists and colleagues found broad evidence that supports the controversial 'dilution effect hypothesis,' which suggests that biodiversity limits outbreaks of disease among humans and wildlife.

Scientists develop new technique to analyze bacterial populations

Scientists from the Icahn School of Medicine at Mount Sinai have developed a new technique to more precisely analyze bacterial populations, to reveal epigenetic mechanisms that can drive virulence. The new methods hold the promise of a potent new tool to offset the growing challenge of antibiotic resistance by bacterial pathogens.

Researchers find lymphatic vessels in the central nervous system

In a study published in The Journal of Experimental Medicine, researchers working at the Wihuri Research Institute and the University of Helsinki report a surprising finding that challenges current anatomy and histology textbook knowledge: Lymphatic vessels are found in the central nervous system where they were not known to exist.

Scientists find way to accelerate wound healing in diabetic mice

One of the body's own tools for preventing wound infections may actually interfere with wound healing, according to new research from Boston Children's Hospital. In a study published online in Nature Medicine, scientists from the hospital's Program in Cellular and Molecular Medicine found they could speed up wound healing in diabetic mice by keeping immune cells called neutrophils from producing bacteria-trapping neutrophil extracellular traps (NETs).

Better way to predict survival in patients with HPV-positive oropharyngeal cancer

According to Sturgis, the incidence of HPV-positive oropharyngeal carcinoma has increased dramatically in recent years. Although patients with HPV-positive disease have a better prognosis than those with HPV-negative disease, researchers are still seeking a better understanding of what group of patients is more likely to respond to treatment.

Study explores role of ALK1 protein in breast cancer metastasis

Pietras said that although prognosis for breast cancer is relatively good when detected in its early stages, metastatic disease is the cause of 90 percent of all cancer-related deaths. Therefore, learning more about the metastatic process and finding new cures to inhibit disease spread is at the center of clinical attention.

Researchers examine proteins on surface of naive CD4+ T cells

The team headed by Dr. Kathrin Suttner, who, together with Prof. Dr. Carsten Schmidt-Weber, heads the airway immunology research group at the Helmholtz Zentrum München and Technische Universität München, concentrated its work on the so-called naive CD4+ T cells.

Researchers identify gene variant that makes breast cancer cells more aggressive

A particular human gene variant makes breast cancer cells more aggressive. Not only are these more resistant to chemotherapy but also leave the primary tumour and establish themselves in other parts of the body in the form of metastases. An international group of researchers led by Lukas Kenner of MedUni Vienna has now identified a gene, AF1q, as being substantially responsible for this and recognized it as a possible starting point for more accurate diagnosis and potential targeted therapeutic approaches.

Rising levels of carbon dioxide affect plants' absorption of nitrogen

The rapidly rising levels of carbon dioxide in the atmosphere affect plants' absorption of nitrogen, which is the nutrient that restricts crop growth in most terrestrial ecosystems. Researchers at the University of Gothenburg have now revealed that the concentration of nitrogen in plants' tissue is lower in air with high levels of carbon dioxide, regardless of whether or not the plants' growth is stimulated.

LMU clinicians reveal mechanism involved in determining lifetime of antibody-producing cells

Clinicians at Ludwig-Maximilians-Universitaet in Munich have elucidated a mechanism involved in determining the lifespan of antibody-producing cells, and identified a promising new biomarker for monitoring autoimmune diseases like multiple sclerosis and lupus erythematosus.

UIC study shows that brain cell density remains constant in normal aging

New, ultra-high-field magnetic resonance images (MRI) of the brain by researchers at the University of Illinois at Chicago provide the most detailed images to date to show that while the brain shrinks with age, brain cell density remains constant.

Triciribine drug may reverse progression of pulmonary fibrosis and pulmonary hypertension

Researchers at the University of Georgia have discovered that the drug triciribine may reverse or halt the progression of pulmonary fibrosis and pulmonary hypertension, two respiratory diseases that are almost invariably fatal.

Scientists identify gene mutation linked to anaplastic oligodendroglioma

Scientists have identified a gene mutation linked to the development of an aggressive form of brain cancer. Researchers found that errors in a gene known as TCF12 - which plays a key role in the formation of the embryonic brain are associated with more aggressive forms of a disease called anaplastic oligodendroglioma.
