Processes underlying the damaging effects of brain injury can preserve memory function

A study examining the effect of the immune receptor known as Toll-like Receptor 4, or TLR4, on how memory functions in both the normal and injured brain has found vastly different cellular pathways contribute to the receptor's effects on excitability in the uninjured and injured brain.

Researchers identify new therapeutic target to switch-off cancer stem cells

Tumors are not a uniform mass of cells. Colon cancers bear differentiated-like cells, similar to the functional cells of the intestinal wall, and pluripotent cells--the so-called tumour stem cells.

New study explores brain regions that drive the instinct to form lasting bonds

When it comes to forming a lasting bond, our longing for a partner may be as important as - if not more important than - how we react when we're with them, suggests a surprising new brain imaging study published in the Proceedings of the National Academy of Sciences.

Scientists discover the 'brain's steering wheel' that controls mice’s movements

Walking is one of the most important motor skills for animals and humans. And for almost all people, being able to walk is deeply essential. In spite of this, researchers are still working to map out which signals and electrical impulses from the brain control our walking.

Innovative approach turns 'cold' tumors 'hot' to improve cancer immunotherapy

Scientists from the Tumor Immunotherapy and Microenvironment research group led by Dr Bassam Janji at the Luxembourg Institute of Health Department of Oncology, and the Swedish pharma company Sprint Bioscience published the results of an innovative approach that turns “cold” tumors “hot”. “Cold”, immune-desert tumors are classically immunotherapy-resistant.
