Researchers at EPFL have created artificial molecules that can help the immune system to recognize and attack cancer tumors. Immunotherapies are breakthrough treatments that stimulate the patient’s immune cells to attack the tumor through the recognition of tumor antigens. They can be very effective, but currently can only cure a minority of patients with solid tumors. Researchers and physicians are now looking into ways of increasing the precision and strength of the immune attack on the tumor.

One approach is the “dendritic cell vaccine...

Highlights • Non-classical MHC class I molecules promote homeostatic immunity to the microbiota • Commensal-specific T cells express immunoregulatory and tissue repair signatures • Commensal-specific T cells accelerate wound closure

Insights may inform wound management techniques. Beneficial bacteria on the skin of lab mice work with the animals’ immune systems to defend against disease-causing microbes and accelerate wound healing, according to new research from scientists at the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health. Researchers say untangling similar mechanisms in humans may improve approaches to managing skin wounds and treating other damaged tissues.

Like humans and other mammals, mice are inhabited by the microbiome...

Named after the Greek goddess who spun the thread of life, Klotho proteins play an important role in the regulation of longevity and metabolism. In a recent Yale-led study, researchers revealed the 3D structure of one of these proteins, beta-Klotho, illuminating its intricate mechanism and therapeutic potential. The study findings, published in Nature, could have implications for therapies developed to treat a wide range of medical conditions, including diabetes, obesity, and certain cancers, the researchers said.

The Klotho family of 2 receptor proteins are located on the surface of cells of specific tissues...

Periostin (shown in pink) is being used in the clinic as a marker for allergic diseases such as asthma as well as atopic dermatitis. Left image: Periostin is overexpressed in atopic dermatitis. Right image: Blocking LIGHT also blocks periostin expression.

Finding provides a novel therapeutic target for the treatment of severe eczema, a chronic inflammatory skin condition that is driven by an allergic reaction. In their latest study, researchers at La Jolla Institute reveal an important player that promotes skin inflammation in atopic dermatitis and the characteristic thickening of the skin...
