The intricate relationship that exists between humans and the gut microbiome has become a hot research topic, and scientists are constantly uncovering new reasons why a healthy diet can lead to a healthier life. Dietary fibers are a particularly important aspect of this connection. When we ingest these compounds, which are mainly found in plant-based …
Image Caption: T cells are a type of white blood cell that play a central role in the immune response. Photo credit: NIAID. When you need a bit of motivation, it often has to come from within. New research suggests cancer-fighting immune cells have found a way to do just that. Scientists at the University …
A new mechanism that slows down and may even prevent the natural aging of immune cells – one of the nine ‘hallmarks of aging’* – has been identified by an international team led by UCL scientists. Published in Nature Cell Biology, researchers say the discovery in-vitro (cells) and validated in mice was ‘unexpected’ and believe …
Chimeric antigen receptor (CAR) T cell therapy is a type of immunotherapy that uses genetically modified versions of a person’s own immune cells to fight cancer. Current models of CAR T cells have several limitations, including a tendency to stop working after a period of time. A team of scientists at MSK’s Sloan Kettering Institute …
Scientists have identified a series of molecular candidates for those parts of dog allergens that cause immune reactions in people—the first step in developing a vaccine against most causes of dog allergies. There have been many research efforts describing the nature and progression of dog allergies, but there have been very few applied studies that …
A new study that upends the idea that T cells can perfectly distinguish between healthy and infected cells may lead to improved approaches to treating cancer and autoimmune diseases. When it comes to distinguishing a healthy cell from an infected one that needs to be destroyed, the immune system’s killer T cells sometimes make mistakes. …
In a letter to health care providers that is current as of 11/3/2020, the U.S. Food and Drug Administration (FDA) is alerting clinical laboratory staff and health care providers that false-positive results can occur with antigen tests, including when users do not follow the instructions for use of antigen tests for the rapid detection of …
The US FDA has granted an emergency use authorization to Becton Dickson and CO for a rapid COVID-19 antigen test that can be administered at the point of care to produce results within 15 minutes; and in early trading shares for the company have increased $5.40 which is about 2.3%. Antigen testing works by scanning …
Mechanism by which good microbiota bacteria help maintain a healthy intestine have been identified by researchers from Baylor College of Medicine, as published in the journal Immunity. Findings of this study have shown that microbiota balance intestinal immune responses and protect against inflammation through interactions with epithelial and immune cells, findings that suggest manipulating good …
Nanobodies are therapeutic proteins which are derived from heavy chain domains of IgG of camelids, free of many of the complications and side effects of conventional antibodies. Conventional antibodies are proteins comprised of 2 heavy chains and 2 light chains, each chain contributing to antigen binding sites, target binding has noncovalently associated variable domains: …
