Cell signaling is vital for cells to communicate and coordinate their activities, not just in the human body, but in all organisms. There are thousands of signaling pathways, ranging from protein homeostasis to carcinogenesis and biofilm formation.

Engineered protein silences harmful T cells in autoimmune disease

An engineered protein turns off the kind of immune cells most likely to damage tissue as part of Type-1 diabetes, hepatitis, multiple sclerosis, shows a new study in mice.

Protein cleavage mechanism sheds light on severe childhood ciliopathies

New research by Sumeda Nandadasa, PhD, reveals how a key protein associated with Meckel-Gruber syndrome, nephronophthisis, Joubert syndrome and other ciliopathies is cut in half to perform two separate functions, both of which are fundamental to the healthy development of children.

Study finds high levels of iron in the brains of people diagnosed with Down syndrome and Alzheimer's

Scientists at the USC Leonard Davis School of Gerontology have discovered a key connection between high levels of iron in the brain and increased cell damage in people who have both Down syndrome and Alzheimer's disease.

Targeting PME-1 may offer new strategies for treating neurological disorders and cancer

PME-1 is a protein that modifies other proteins by removing methyl groups, but high levels of PME-1 are observed in some diseases, including Alzheimer's disease (AD) and cancer.

lncRNAs shape the tumor microenvironment and drive cancer development

The tumor microenvironment (TME) is a complex and dynamic network consisting of tumor cells, immune cells, stromal cells, extracellular matrix (ECM), cytokines, and growth factors, all interacting to influence tumorigenesis, progression, and metastasis.

QRICH1 protein discovery opens new avenues for cancer and autoimmune therapies

In a study of the immune systems of mice, scientists at Johns Hopkins Medicine say they have found a new role for a protein, QRICH1, which could become a target for drugs to dial up or down the activation of T cells to fight cancers and autoimmune diseases.

What blueberries do and don’t do for your microbiome and heart

Regular blueberry consumption for 12 weeks enriched Coriobacteriales incertae sedis in the gut microbiota of older overweight adults. However, this microbial shift was not linked to significant improvements in cardiometabolic biomarkers.

Study uncovers how resistance to chemotherapies may occur in some cancers

Investigators at Mass General Brigham have uncovered how resistance to chemotherapies may occur in some cancers. Researchers focused on a pathway that harnesses reactive oxygen species (ROS) to kill cancer cells.

New insights into how glutamate opens brain cell signaling channels

In an effort to understand how brain cells exchange chemical messages, scientists say they have successfully used a highly specialized microscope to capture more precise details of how one of the most common signaling molecules, glutamate, opens a channel and allows a flood of charged particles to enter.

Scientists link emulsifiers in processed foods to allergy and immune disorders

Review identifies common food additives in ultra-processed foods—particularly emulsifiers like carrageenan and polysorbate 80—as key drivers of gut dysbiosis, inflammation, and allergic diseases by disrupting intestinal barriers and activating proinflammatory pathways.
