Medical Xpress / Skin renews despite 60% to 70% fibroblast depletion in mice, challenging long-held assumption
Human skin is constantly rebuilding itself. Every few weeks, the outermost layers shed and are replaced by new cells pushed up from the base. For decades, scientists believed this renewal depended heavily on fibroblasts, ...
Medical Xpress / What a 'silenced' chromosome can tell us about autoimmunity
Systemic lupus erythematosus (SLE), the most common form of lupus, is an autoimmune disorder that occurs more frequently in women. Having multiple X chromosomes has been associated with an increased risk of developing lupus; ...
Medical Xpress / Aging reshapes the ovary long before reproductive function ends
Aging affects every organ in the body, yet we still know little about how the ovary changes over time. In a new study published in Nature Aging, Yale researchers created one of the most detailed maps of the aging ovary to ...
Medical Xpress / Early immune clues that determine who develops TB may lead to new ways to intervene earlier and stop the disease
A quarter of the global population is estimated to have been infected with Mycobacterium tuberculosis, yet only 5%–10% of those infected go on to develop active tuberculosis (TB). "The big question has always been what distinguishes ...
Medical Xpress / New technology helps reveal how the heart generates cells with regenerative potential
Two research teams at the Centro Nacional de Investigaciones Cardiovasculares Carlos III (CNIC) have developed a pioneering technique in Spain to characterize the proteome of individual cardiomyocytes—the cells responsible ...
Medical Xpress / Mapping the hidden rules of a key immune sensor
The immune system depends on molecular alarms that detect danger inside cells. One of these alarms is STING, short for "stimulator of interferon genes." STING helps cells respond to infections, damaged DNA and cancer. When ...
Medical Xpress / Hidden protein linked to severe COVID-19 and lung disease risk
A genetic difference carried by nearly one in three people may increase the risk of severe COVID-19 and lung fibrosis by disrupting the function of a previously unknown protein, according to a new study published in Nature ...
Medical Xpress / Simple eye scan in preterm infants may help predict brain development
Very preterm infants face up to a 50% higher risk of developmental challenges affecting movement, learning, language and behavior. Today, many of those challenges are not fully recognized until later in infancy or early childhood. ...
Medical Xpress / Most patients want cancer diagnoses from doctors, not portals, survey finds
The widespread use of electronic patient portals to provide quick access to test results presents health care professionals with an important challenge: How should new cancer diagnoses be communicated?
Medical Xpress / Personalized brain imaging may improve outcomes for treatment-resistant depression
A new randomized clinical trial from investigators at Mass General Brigham's Neuroscience Institute and Department of Psychiatry suggests that using personalized brain imaging to guide transcranial magnetic stimulation (TMS) ...
Medical Xpress / Hidden mechanism driving joint tissue growth in rheumatoid arthritis has been found
Researchers at Hospital for Special Surgery (HSS) have identified a specialized population of immune cells that plays a central role in driving abnormal tissue growth in rheumatoid arthritis (RA), offering new insight into ...
Medical Xpress / Age limits alone won't fix smartphone risks, suggests study
Researchers at Children's Hospital of Philadelphia (CHOP), in collaboration with the University of California, Berkeley, and the University of Pennsylvania Perelman School of Medicine, found that a year after receiving their ...
