Infection with the influenza virus leads to lung injury through inflammation over-activation that causes collateral damage to cells required for breathing. Such damage can be life-threatening, but scientists have a new preventative treatment. A team from St. Jude Children's Research Hospital, University of Houston, Tufts University School of Medicine and Fox Chase Cancer Center created a drug that can prevent flu-induced lung injury. In a mouse model, the drug achieves a novel balance between shutting down runaway inflammation and allowing the immune system to stop the virus.

Swapping red meat for 'forage fish', such as herring, sardines, and anchovies, could save up to 750,000 lives a year in 2050 and significantly reduce the prevalence of disability as a result of diet-related disease, suggests a data analysis published in the open access journal BMJ Global Health.

Adopting this type of diet would be especially helpful for low and middle income countries, where these fish are cheap and plentiful, and where the toll taken by heart disease, in particular, is high, say the researchers.

A new study by Upstate Medical University researchers shows that recreational cannabis use may offer protection against cognitive decline.

The study, done by Master of Public Health (MPH) student Zhi Chen and Professor Roger Wong, Ph.D., MPH, MSW, analyzed a large data set from the CDC and found that compared to non-users, non-medical cannabis use, such as for recreational purposes, was significantly associated with 96 percent decreased odds of subjective cognitive decline (SCD).

The lab of Yongchao C. Ma, PhD, at Stanley Manne Children's Research Institute at Ann & Robert H. Lurie Children's Hospital of Chicago discovered a fundamental biological mechanism that could lead to new treatments for neurological diseases, such as spinal muscular atrophy (SMA) and autism, as well as different cancers. The study was published in the journal Human Molecular Genetics.

Dr. Ma's team found that chemical modification of RNA (called RNA methylation) regulates mitochondrial function.

The Janus kinase 2 (JAK2) protein mediates signaling from several cytokine receptors in the regulation of hematopoiesis and immune responses. Somatic mutations in human JAK2 lead to constitutive activation and cytokine-independent signaling and underlie several hematological malignancies from myeloproliferative neoplasms (MPN) to acute leukemia and lymphomas. JAK2 contains an active kinase domain and an inactive pseudokinase domain. Interestingly, pathogenic mutations mainly occur in the regulatory pseudokinase domain.

A novel treatment for leukemias and lymphomas that arise from immune system T cells, developed by investigators at the Johns Hopkins Kimmel Cancer Center and its Ludwig Center and Lustgarten Laboratory, was found to be effective at killing these cancers in mice bearing human T-cell tumors.

The therapy, an antibody-drug conjugate (ADC), combines an antibody that targets a protein called TRBC1 expressed on the surface of T-cell cancers with an anti-cancer drug, called SG3249.

Changes in the gut microbiome have been implicated in a range of diseases including type 2 diabetes, obesity, and inflammatory bowel disease. Now, a team of researchers at the Broad Institute of MIT and Harvard along with Massachusetts General Hospital has found that microbes in the gut may affect cardiovascular disease as well. In a study published in Cell, the team has identified specific species of bacteria that consume cholesterol in the gut and may help lower cholesterol and heart disease risk in people.
