Proteins are complex molecules that are made up of amino acids. They can be found in every cell in the body, and carry out vital processes that keep human beings alive. Mutations in proteins can lead to a multitude of diseases, the most common being cancer.

Ribosomes in cells play a crucial role in protein folding

Scientists at UCL have discovered a novel role played by ribosomes during the folding of new proteins in cells, described in their paper in Nature.

Discovery of Tr1 cells as a barrier to cancer immunotherapy offers new hope for treatment

Immunobiologists Robert Schreiber, PhD, (left) and Hussein Sultan, PhD, of Washington University School of Medicine in St. Louis, found that a subset of immune cells that normally puts the brakes on the immune system to prevent it from attacking the body's healthy cells inadvertently also dampens cancer immunotherapy.

New research uncovers mechanisms behind heart damage from CTLA-4 blockade

Cytotoxic T-lymphocyte antigen 4 (CTLA-4) is a protein receptor on T immune cells that prevents the cells from killing other cells, such as cancer cells.

NUS study finds 5-HTP enhances sleep quality and gut health in older adults

National University of Singapore (NUS) nutritionists have found that 5-Hydroxytryptophan (5-HTP) supplementation can improve sleep quality in Singaporean older adults, particularly in individuals with poor sleep patterns, and manage their gut microbiome composition.

From discovery to approval: Vorasidenib approved by FDA for treatment of IDH-mutant gliomas

A new drug for treatment of a type of brain cancer, called IDH-mutant low-grade glioma, was approved Aug. 6 by the U.S. Food and Drug Administration (FDA).

METRNL protein identified as key player in cancer progression

A protein called Meteorin-like (METRNL) in the tumor microenvironment saps energy from T cells, thereby severely limiting their ability to fight cancer, according to new research directed by investigators at the Johns Hopkins University School of Medicine and the Johns Hopkins Kimmel Cancer Center and its Bloomberg~Kimmel Institute for Cancer Immunotherapy. Finding ways to block the effects of METRNL signaling on tumor-infiltrating T cells may allow these immune cells to regain the energy necessary to eliminate tumors.

Researchers uncover immune system barrier to cancer treatment

By recruiting the immune system to combat tumor cells, immunotherapy has improved survival rates, offering hope to millions of cancer patients. However, only about one in five people responds favorably to these treatments.

Study uncovers roles of certain brain cells in Alzheimer's plaque formation

A study in Nature Neuroscience found that both neurons and oligodendrocytes contribute to amyloid-β plaque burden in Alzheimer's disease, highlighting new therapeutic targets.

Study uncovers how TREM2 R47H mutation affects Alzheimer's plaques

Researchers led by the University of California, Irvine have discovered how the TREM2 R47H genetic mutation causes certain brain areas to develop abnormal protein clumps, called beta-amyloid plaques, associated with late-onset Alzheimer's disease.

Omega-3 fatty acids show potential in protecting brain health in older adults

Researchers assess the role of ω-3 polyunsaturated fatty acids (PUFAs) in reducing white matter lesion accumulation and neuronal integrity degeneration.

Cambridge experts question efficacy and practicality of new amyloid immunotherapy drugs

Cambridge researchers have cast doubt on whether new amyloid immunotherapy drugs will have the desired effect of significantly reducing the impact of Alzheimer's disease.

New target identified for melanoma resistant to current therapies

Some proteins, such as programmed cell death protein 1 (PD1), can stop the immune system from attacking cancer cells and, therefore, support the growth of cancer.

Mini intestines uncover mechanisms behind COVID-19-related diarrhea and potential treatments

Working with human stem cells that form a kind of "mini intestine-in-a-dish," Johns Hopkins Medicine scientists say they have found several molecular mechanisms for COVID-19-related diarrhea, suggesting potential ways to control it.
