A Step Toward Diabetes Immunotherapy

Harvard Medical School researchers at Boston Children’s Hospital have reversed type 1 diabetes in mice by infusing blood stem cells pretreated to produce more of a protein called PD-L1, which is deficient in mice and people with type 1 diabetes. The stem cells curbed the autoimmune reaction in cells from […]

Targeting cancer without destroying healthy T-cells

The team of researchers, working with biopharmaceutical company Autolus Ltd, have discovered a method of targeting the cancer without destroying healthy T-cells, essential to the immune system. Lymphomas arise when immune cells, called lymphocytes, that protect us against germs, become cancerous. There are two types of lymphocytes: B-cells and T-cells. […]

Study reveals how drug could derail synapse loss in Alzheimer's disease

A recent multi-centre study, led by King’s College London and the University of Manchester, has established that synapse loss in Alzheimer’s disease is driven by a specific signalling pathway. This pathway is called the Wnt-planar cell polarity (PCP) signalling pathway and it may be pivotal to the progressive neurodegeneration seen […]

Discovery suggests better way to treat certain prostate cancers, lymphomas

Certain prostate cancers and lymphomas have a major genetic weakness that doctors can exploit to help save patients’ lives, researchers at the University of Virginia School of Medicine have discovered. The weakness makes the subset of cancers particularly vulnerable to chemotherapy and radiation therapy, suggesting that those approaches should be […]

Fighting cancer with cancer: 3-D cultured cells could drive precision therapy

Honeycomb-like arrays of tiny, lab-grown cancers could one day help doctors zero in on individualized treatments for ovarian cancer, an unpredictable disease that kills more than 14,000 women each year in the United States alone. A team of researchers has devised a process that can grow hundreds of cultured cell […]

Gene shown to induce undifferentiated cells during tadpole tail regeneration

A group of researchers at the University of Tokyo found that a particular gene, interleukin-11, functions as a key factor in inducing and maintaining undifferentiated cells when tadpoles regenerate their tail. Some animal species have the remarkable ability to reconstruct lost appendages. The African clawed frog (Xenopus laevis) is one such […]

Recipe to make human blood-brain barrier

The blood-brain barrier is the brain’s gatekeeper. A nearly impenetrable shield of cells, it keeps toxins and other agents that may be in circulating blood from gaining access to and harming the brain. A critical anatomical structure, the barrier is the brain’s first and most comprehensive line of defense. But […]

How Chronic Inflammation Tips the Balance of Immune Cells to Promote Liver Cancer

Study explains success of some types of cancer immunotherapy, provides new targets for the development of additional immunotherapies. Chronic inflammation is known to drive many cancers, especially liver cancer. Researchers have long thought that’s because inflammation directly affects cancer cells, stimulating their division and protecting them from cell death. But […]
