Cells gone mad

What are tumor cells? These are cells that are "crazy", they behave incorrectly, not in the way the body needs. And the most dangerous "crazy" are tumor stem cells.

A promising candidate for drugs against neurodegenerative diseases

Researchers have synthesized a compound whose oral administration significantly slows down the progression of Parkinson's disease, and possibly other neurodegenerative diseases caused by the formation of toxic protein aggregates in brain tissue.

Antibodies turn hematopoietic cells into nerve stem cells

By a lucky chance, scientists have created antibodies whose interaction with the receptor of the surface of hematopoietic stem cells of the bone marrow transforms their precursor cells of neurons.

A new method of delivering radioisotopes to metastases

An unusual method of cancer treatment: Listeria bacteria selectively infect cancer cells, acting as couriers for the delivery of radioisotopes, the radiation of which destroys tumor metastases.

Gene therapy will cure parkinsonism

To cope with Parkinson's disease, scientists have proposed using nanoparticle-packed genes encoding a "medicinal" protein. And in order to bypass the blood-brain barrier, they proposed to instill DNA nanoparticles into the nose.

The risk of developing senile dementia is reduced

Improving preventive measures and medical care reduces the risk of developing senile dementia, but you should not relax, since the number of such patients will grow along with an increase in life expectancy.

How does "Homunculus" work?

In six cells of the "Homunculus", cells of organs (intestines, liver, lungs, heart, brain, skin) are cultivated, washed by the culture medium. In a closed system, conditions have been created that simulate the "life" of one hundred thousandth of a person.

Caution: Gold nanoparticles!

Even in very low concentrations, gold nanoparticles, including those included in personal hygiene products, disrupt the work of adipose tissue stem cells, potentially impairing the ability of many organs to regenerate and, accordingly, accelerating the aging of the body.

The role of cholesterol in Alzheimer's disease – "acquired Down syndrome"

Cholesterol disrupts the process of chromosome distribution during cell division, which leads to the accumulation in the body of cells with trisomy on the 21st chromosome, which is the cause of Down syndrome, and increases the risk of developing Alzheimer's disease and other pathologies.

Is senile dementia associated with increased plasticity of synapses?

Contrary to the generally accepted opinion, it turned out that with age, the rate of formation of new and disappearance of existing synapses between brain neurons does not decrease, but increases, and the size of synapses changes more than in the brains of young animals.

Biogerontology for dummies

Biogerontology is a very broad field of knowledge that studies the processes of aging and the mechanisms of combating it. It includes many other branches of science, such as regenerative medicine, various intracellular processes and processes occurring at the body level.
