Regulatory T cells (Treg cells) are a specialized subgroup of immune cells that play a central role in the human immune system. These cells can suppress erroneous and therefore harmful immune reactions that can lead to autoimmune diseases, for example. Furthermore, they actively promote the regeneration of tissue after injuries and thus orchestrate the wound healing process.
In a new study published in Cancer Immunology Research, scientists at the Icahn School of Medicine at Mount Sinai have developed a novel method to generate billions of rare immune cells known as conventional type I dendritic cells (cDC1s), potentially paving the way for a new class of off-the-shelf cellular cancer vaccines.
Semen, sperm, spunk, cum, ejaculate, pre-cum, seminal fluid. These are just some of the many words we use to describe what comes out of an erect penis.
Some autistic teens often adopt behaviors to mask their diagnosis in social settings helping them be perceived—or "pass"—as non-autistic. For the first time, researchers are able to observe brain functions that differ in those who "pass as non-autistic," which could lead to a better understanding of the cognitive toll of this kind of masking, and of how these individuals could be more effectively supported.
Scientists have corrected gene mutations in mice causing an ultra-rare disease by editing DNA directly in the brain with a single injection, a feat with profound implications for patients with neurological diseases.
Scientists at UC San Francisco and Gladstone Institutes have identified cancer drugs that promise to reverse the changes that occur in the brain during Alzheimer's, potentially slowing or even reversing its symptoms.
A research group in the Department of Pharmacology of the University of the Basque Country has investigated the adverse reactions that antipsychotics can cause in the mouth. The study was based on data from the European pharmacovigilance database EudraVigilance and revealed that the most common problems are related to salivary flow disorders (such as excessive salivation and dry mouth), oral inflammation and tooth loss. The research is published in the journal Oral Diseases.
Rural oncologists reported the loss of expertise and professional support as key impacts of the departure of "linchpin colleagues," according to a new Dartmouth-led study published in the journal JCO Oncology Practice. The study, which shares insights about the effects of specialist scarcity in rural settings, is helping researchers understand what strategies may work best in addressing gaps in care.
As the latest wave of COVID-19 shows no signs of abating, University of South Australia experts say it's not just booster shots that could offer protection—healthy levels of vitamin D may also play a role.
A new online tool developed by researchers at the University of Louisville promises to speed up the discovery of treatments for brain and nerve tumors, especially rare ones that have had limited research attention.
Why do some people keep making choices that hurt them, even when the outcomes are obvious?
Popular GLP-1 drugs help many people drop tremendous amounts of weight, but the drugs fail to provide a key improvement in heart and lung function essential for long-term good health, University of Virginia experts warn in a new paper.
Rehab hospitals that help people recover from major surgeries and injuries have become a highly lucrative slice of the health care business. But federal data and inspection reports show that some run by the dominant company, Encompass Health Corp., and other for-profit corporations have had rare but serious incidents of patient harm and perform below average on two key safety measures tracked by Medicare.
People view physicians more negatively who disclose the use of artificial intelligence in their practice. This is the conclusion of a new study by psychologists from Würzburg published in JAMA Network Open.
Experts in vaccines and vaccination—including pediatricians—work together throughout the year to update the Recommended Child and Adolescent Immunization Schedule for ages 18 years or younger.
When you look at the world around you, it might feel like your eyes and brain work in perfect sync—taking in a smooth, continuous stream of information. But according to new research led by cognitive neuroscientist Prof. Ayelet N. Landau from the Hebrew University of Jerusalem, that's not quite how the brain works. Instead, attention behaves more like a strobe light: flickering in and out at a steady rhythm.
A new study published by Cleveland Clinic researchers in Diabetes, Obesity and Metabolism investigating the genetic underpinnings of weight loss response has identified a gene, neurobeachin (NBEA), as a predictor of how individuals respond to GLP-1RAs, the class of medications behind popular treatments like liraglutide and semaglutide.
Researchers at the University of Pittsburgh and Carnegie Mellon University collaborated to create a customized app based on artificial intelligence that may help people with multiple sclerosis track their symptoms—and even predict them.
Accurate removal of tumors is the most critical aspect of cancer surgery, yet it remains a significant challenge in clinical practice. In breast cancer, for example, the positive margin rate—where cancer cells remain at the surgical boundary—can reach up to 35%, often requiring reoperation and increasing the risk of recurrence.
