CRISPR Screen Identifies Gene That Helps Cells Resist West Nile, Zika Viruses

UT Southwestern researchers today report the first use of CRISPR genome-wide screening to identify a gene that helps cells resist flavivirus infection. That nasty class of pathogens includes West Nile virus, dengue fever, Zika virus, and yellow fever. In a study published in Nature Microbiology, the team led by Dr. John Schoggins, Assistant Professor of Microbiology, used […]

Higher Doses of Rifampin Appear More Effective in Fighting TB Without Increasing Risk of Adverse Events

Higher daily doses of rifampin, a cornerstone of tuberculosis treatment, killed more TB bacteria in sputum cultures, and the higher doses did so without increasing the adverse effects of treatment, according to a randomized controlled trial published online in the American Thoracic Society’s American Journal of Respiratory and Critical Care Medicine. In “Efficacy and Safety of High-Dose Rifampin […]

Penn Study Reveals New Therapeutic Target for Slowing the Spread of Flu Virus

Researchers show altering the molecular interactions between the flu virus and host genes stunts virus replication Influenza A (flu A) hijacks host proteins for viral RNA splicing and blocking these interactions caused replication of the virus to slow, according to new research published in Nature Communications by Kristin W. Lynch, PhD, chair of the department of […]

New Lyme Disease Tests Could Offer Quicker, More Accurate Detection

New tests to detect early Lyme disease – which is increasing beyond the summer months – could replace existing tests that often do not clearly identify the infection before health problems occur. In an analysis published on December 7 in Clinical Infectious Diseases, scientists from Rutgers University, Harvard University, Yale University, the National Institute of Allergy […]

‘Molecular Scissors’ Could Be Key to Cutting Off Diseases Including HIV Infection

One way to fight diseases including HIV infection and autoimmune disorders could involve changing how a naturally occurring enzyme called SAMHD1 works to influence the immune system, new research suggests. The study, led by researchers from The Ohio State University, details how the enzyme influences proteins that stimulate the immune response. SAMHD1 isn’t a molecular […]

Individuals with HIV at Higher Risk for Heart Disease

A review of more than 80 studies reveals that changes in the immune cells of people with human immunodeficiency virus (HIV) infection may increase their risk of cardiovascular disease (CVD). The review is published in the journal Physiology. Combination antiretroviral therapy (cART) consists of a “cocktail” of several drugs that work together to reduce the amount of detectable […]

Immune Cells Play Key Role in Early Breast Cancer Metastasis Even Before a Tumor Develops

Mount Sinai researchers have discovered that normal immune cells called macrophages, which reside in healthy breast tissue surrounding milk ducts, play a major role in helping early breast cancer cells leave the breast for other parts of the body, potentially creating metastasis before a tumor has even developed, according to a study published in Nature Communications. […]

Immune Cells Produce Wound Healing Factor, Could Lead To New IBD Treatment

Specific immune cells have the ability to produce a healing factor that can promote wound repair in the intestine, a finding that could lead to new, potential therapeutic treatments for inflammatory bowel disease (IBD), according to a new research study. The research team, led by Georgia State University and the University of Michigan, wanted to […]

Experimental HIV vaccine regimen is well-tolerated, elicits immune responses

Results from an early-stage clinical trial called APPROACH show that an investigational HIV vaccine regimen was well-tolerated and generated immune responses against HIV in healthy adults. The APPROACH findings, as well as results expected in late 2017 from another early-stage clinical trial called TRAVERSE, will form the basis of the decision whether to move forward […]

Nanoparticles Reprogram Immune Cells to Fight Cancer

Researchers at Fred Hutchinson Cancer Research Center have developed biodegradable nanoparticles that can be used to genetically program immune cells to recognize and destroy cancer cells — while the immune cells are still inside the body. In a proof-of-principle study to be published April 17 in Nature Nanotechnology, the team showed that nanoparticle-programmed immune cells, […]

Cytotoxins Contribute to Virulence of Deadly Epidemic Bacterial Infections

Beginning in the mid-1980s, an epidemic of severe invasive infections caused by Streptococcus pyogenes (S. pyogenes), also known as group A streptococcus (GAS), occurred in the United States, Europe, and elsewhere. The general public became much more aware of these serious and sometimes fatal infections, commonly known as the “flesh-eating disease.” Potent cytotoxins produced by […]

Patients with Severe Chronic Rhinosinusitis Show Improvement with Verapamil Treatment

A small clinical trial at Massachusetts Eye and Ear found that patients with chronic rhinosinusitis (CRS) with nasal polyps improved with Verapamil therapy A clinical trial studying the use of Verapamil (a drug currently in use for cardiovascular disease and cluster headache) in alleviating chronic rhinosinusitis (CRS) with nasal polyps revealed significant improvement in the […]

‘Collateral’ Lethality May Offer New Therapeutic Approach for Cancers of the Pancreas, Stomach and Colon

Cancer cells often delete genes that normally suppress tumor formation. These deletions also may extend to neighboring genes, an event known as “collateral lethality,” which may create new options for development of therapies for several cancers. Scientists at The University of Texas MD Anderson Cancer Center have discovered that during early cancer development when a […]

Novel Metagenomics Pathogen Detection Tool Could Change How Infectious Diseases Are Diagnosed

Scientists at the University of Utah, ARUP Laboratories, and IDbyDNA, Inc., have developed ultra-fast, meta-genomics analysis software called Taxonomer that dramatically improves the accuracy and speed of pathogen detection. In a paper published today in Genome Biology, the collaborators demonstrated the ability of Taxonomer to analyze the sequences of all nucleic acids in a clinical […]
