The role of autophagy in beta-amyloid secretion

Autophagy, a key cellular mechanism of self-purification, mediates the formation of beta–amyloid plaques – one of the signs of Alzheimer's disease - and may be a potential target of drugs for the treatment of this disease.

Taking anabolic steroids will be remembered for years

In the muscles of people who have taken anabolics for a short time, a cellular memory mechanism is formed, and even short-term exposure to anabolic steroids can affect the process of building muscle mass for years.

The variety of symptoms of Parkinson's disease has been explained

The researchers were able to describe and obtain two different types of aggregates of the alpha-synuclein protein – the causes of Parkinson's disease. One of them is much more toxic and has a more pronounced ability to damage neurons.

Alzheimer's disease, cholesterol and sirtuins

Disorders associated with cholesterol-carrying protein ApoE4 and Alzheimer's disease, such as the formation of phosphorylated tau protein and beta-amyloid, can be prevented by increasing the level of one of the "anti-aging" proteins – sirtuins - SirT1.

Alzheimer's disease: another piece of the puzzle

Alzheimer's disease has to be imagined as one big puzzle. Every year, scientists unravel all new parts of it, this time – the role of interaction of prion proteins with beta-amyloid.

Antiretroviral milk

American scientists have discovered a protein in breast milk that "does not let" the human immunodeficiency virus into the body of infants. Tenascin-C may become one of the drugs for the prevention of AIDS.

Why do people get smarter from physical education?

Physical education leads to an increase in the concentration of irisin protein in the brain, which has a neuroprotective effect, increased expression of brain neurotrophic factor (BDNF) and activation of genes responsible for cognitive functions.

Fat and stupid

With obesity, the level of protein in the body decreases, which helps to process fat in the liver, and in the brain serves as an activator for the synthesis of other proteins necessary for the formation of memory.
