Tau protein in Alzheimer's disease looks different at every dementia stage

Research into Alzheimer's disease has long focused on understanding the role of two key proteins, beta amyloid and the tau protein. Found in tangles in patients' brain tissue, a pathological form of the tau protein contributes to propagating the disease in the brain.

Somatic mutation acts as natural gene therapy in patients with GATA2 deficiency

Researchers affiliated with the Center for Cell-Based Therapy (CTC) in Ribeirão Preto, Brazil, have identified for the first time a non-hereditary mutation in blood cells from a patient with GATA2 deficiency, a rare autosomal disease caused by inherited mutations in the gene that encodes GATA-binding protein 2 (GATA2).

Study finds that cannabidiol induces the expression of heme oxygenase 1 in skin cells

At present, cannabidiol has found considerable use not just in the world of cosmetics but also in nutrition and pharmaceutics due to its therapeutic potential.

Scientists identify key source of sensory perception

The brain encodes information collected by our senses. However, to perceive our environment and to constructively interact with it, these sensory signals need to be interpreted in the context of our previous experiences and current aims.

Ultra-processed foods increase risk of muscle pain

A research team from the Universitat Rovira i Virgili (Tarragona - Spain) has observed that following a diet rich in fats and sugars from ultra-processed foods (such as sweet rolls and pastries) for a six-week period increases the number of inflammatory molecules in the organism, which increases the excitability of the muscle nerves.

Astrocytes regulate inhibitory synapses by binding to neurons

In the orchestra of the brain, the firing of each neuron is controlled by two notes--excitatory and inhibitory-- that come from two distinct forms of a cellular structure called synapses.

Study demonstrates utility of novel method in fluorescent labeling

Thirty years ago, the cloning of the green fluorescent protein GFP, together with genetic engineering tools, revolutionized the field by enabling researchers to fuse a fluorescent 'beacon' to any protein of interest so that it can be directly observed in living cells using fluorescence microscopy.
