A significant amount of genetic risk for asthma is likely mediated through altered gene expression within the airway epithelium. That is the conclusion of a National Jewish Health-led study to identify genetic variants that cause asthma by altering the function of airway cells. The team’s paper published March 28, 2022,Continuar Leyendo
University of Notre Dame researchers have discovered another way tumor cells transfer genetic material to other cells in their microenvironment, causing cancer to spread. Notre Dame, In, March 28, 2022.- In their latest study, published in Cell Reports, Crislyn D’Souza-Schorey, the Morris Pollard Professor in the Department of Biological Sciences,Continuar Leyendo
Vagus nerve stimulation (VNS), sometimes referred to as a «pacemaker for the brain,» involves a stimulator device that is implanted under the skin in the chest, with a wire that is wound around the vagus nerve in the neck. It helps prevent seizures by sending regular, mild electrical pulses toContinuar Leyendo
A University of Iowa neuroscience research team has identified a fundamental biochemical mechanism underlying memory storage and has linked this mechanism to cognitive deficits in mouse models of Alzheimer’s Disease and Related Dementias. Iowa City, March 24, 2022.- While working to understand how memories are formed and stored in theContinuar Leyendo
A novel system to control protein aggregation in a model of Parkinson’s disease may answer longstanding questions about how the disease begins and spreads, according to a new study published March 9 in the open-access journal PLOS Biology by Abid Oueslati of Laval University, Quebec, Canada, and colleagues. Initial resultsContinuar Leyendo
Alzheimer’s disease is the most common and best known of the tauopathies, a set of neurodegenerative brain diseases caused by toxic tangles of the protein tau. A study by researchers at Washington University School of Medicine in St. Louis has shown that targeting astrocytes — an inflammatory cell in theContinuar Leyendo
Children previously infected with COVID-19 develop natural circulating antibodies that last for at least seven months, according to a new study led by researchers at UTHealth Houston. The study was published today in Pediatrics. Houston, March 20, 2022.- Researchers examined data from 218 children across the state of Texas betweenContinuar Leyendo
While many people in wealthier countries have been vaccinated against Covid-19, there is still a need for vaccination in much of the world. A new vaccine developed at MIT and Beth Israel Deaconess Medical Center may aid in those efforts, offering an inexpensive, easy-to-store, and effective alternative to RNA vaccines.Continuar Leyendo
Briefly blocking a key molecule when administering the only approved vaccine for tuberculosis vastly improves long-term protection against the devastating disease in mice, researchers from Texas Biomedical Research Institute report this week in the Journal of Immunology. The finding, if it continues to hold true in nonhuman primates and clinicalContinuar Leyendo
By uncovering the subtle difference between two varieties of a protein, researchers from the Perelman School of Medicine at the University of Pennsylvania may have discovered how to eliminate the risk of weight gain from a certain type of diabetes medication. Through this, it’s possible that more patients with diabetesContinuar Leyendo
