Absence of crucial protein may lead to rapid, severe bone loss

The absence of a protein critical to the control of inflammation may lead to rapid and severe bone loss, according to a new University at Buffalo study.

Second man cured of HIV

A London is now free of HIV/AIDS after a stem cell transplant therapy. This is the second such case after the first case of cured HIV in Berlin.

Study elucidates mechanism behind development of steroid diabetes

Steroids are used for treating various diseases such as allergic disorders, but they occasionally cause adverse effects, such as steroid diabetes and other metabolic disturbances. Since steroids act throughout the body, how these adverse effects are caused and by which organ are not well understood.

Scientists use CRISPR to reveal the secret life of antimicrobial peptides

When it comes to the immune system, we usually think about lymphocytes like B and T cells or macrophages going on constant seek-and-destroy missions against invading pathogens like bacteria and viruses.

Neuron-derived estrogen key to making memories

Estrogen in the brain is important to keep neurons communicating and memories being made, scientists report.

New forms of older anti-cancer agent appear to enhance immune response to fight melanoma

Researchers at the Bloomberg~Kimmel Institute for Cancer Immunotherapy at Johns Hopkins and the Johns Hopkins University School of Medicine report two new forms of an older anti-cancer agent they developed appear to enhance the immune system's ability to fight melanoma in mice.

Rubicon level linked to inhibition of autophagic process

Autophagy is an important biological recycling mechanism that is used to maintain homeostasis within all types of animal tissue. Many studies have attempted to understand the relationship between the reduction of autophagy and progression of aging in animals; however, none have provided a clear explanation, until now.

Researchers study animal venoms to identify new medicines for treating diseases

Animal venoms are the subject of study at research center based at the Butantan Institute in São Paulo. But in this case, the idea is not to find antidotes, but rather to use the properties of the venoms themselves to identify molecular targets of diseases and, armed with that knowledge, develop new compounds that can be used as medicines.

Study investigates the role of estrogen in controlling glucose homeostasis

The results of a recent Texas A&M University-led study provide insights into the mechanism by which estrogen can decrease insulin resistance and the production of glucose, reducing incidences of Type 2 diabetes mellitus.

Researchers use mouse models to explain the developmental process behind COPD

The airways and lungs are affected by a range of diseases, but while some have been well characterized and treated, others such as chronic obstructive pulmonary disorder (COPD) are still somewhat of an enigma.

New study extends our knowledge of the link between miRNAs and cancer

The abnormal expression of different classes of molecules is known to be linked to various types of cells becoming cancerous.

Researchers use gene-editing tool CRISPR/Cas9 to limit impact of parasitic diseases

For the first time, researchers at the George Washington University, together with colleagues at institutes in Thailand, Australia, the U.K. and the Netherlands, and more, have successfully used the gene-editing tool CRISPR/Cas9 to limit the impact of parasitic worms responsible for schistosomiasis and for liver fluke infection, which can cause a diverse spectrum of human disease including bile duct cancer.

Identifying genetic factors that lead to squamous cell carcinoma

Skin cancer is on the rise in the United States. Squamous cell carcinoma, the second most common form of cancer in the U.S., has the highest mortality rate of all non-melanoma skin cancers. In roughly two to five percent of patients, the disease will metastasize and spread throughout the body, making it difficult to treat.

Researchers identify hundreds of new genes linked to blindness in lab mice

Hundreds of new genes linked to blindness and other vision disorders have been identified in a screen of mouse strains. Many of these genes are likely important in human vision and the results could help identify new causes of hereditary blindness in patients.

Researchers elucidate central mechanisms of salt-induced hypertension through sympathetic activation

Hypertension is a major risk factor for cardiovascular disease worldwide, and approximately 40% (1 billion) of adults aged 25 and above have been diagnosed with hypertension. A positive correlation between salt intake and blood pressure has long been postulated.

Researchers identify pathway to resolve allergic asthma

A group of Brazilian researchers succeeded in preventing allergic asthma from progressing in experimental models by increasing the amount of a protein. This increase, in turn, blocked the CD4+ T lymphocytes responsible for producing a cytokine that triggers a cascade of events resulting in the onset and progression of the disease.

Genetic defect linked to ALS causes sugar-starved cells to overproduce lipids

A genetic defect tied to a variety of neurodegenerative diseases and mental illnesses changes how cells starved of sugar metabolize fatty compounds known as lipids, a new study led by researchers from the Johns Hopkins Bloomberg School of Public Health shows.
