The dawn of treatment for neurodegenerative diseases

The human nervous system contains hundreds of different types of neurons. These complex cells are extremely important and have a fatal “weakness”: they generally do not regenerate, that is, once they die, they are lost forever. Two types of common neurodegenerative diseases are special: permanent blindness caused by the death of optic ganglion cells, and Parkinson’s disease caused by the death of dopamine neurons. As the global ageing intensifies, there will be more and more patients. How to safely regenerate specific types of neurons in the body to treat different neurodegenerative diseases is the direction that many scientists around the world have been working on. A few days ago, a new scientific research in our country gave people new hope.

The study used the latest gene editing technology to successfully regenerate optic neurons in adult mice for the first time and restore the vision of mice with permanent visual impairment. This means that the neurons of mice can also be regenerated, and this research will provide a new way to treat many neurodegenerative diseases in the future.

Recently, scientists discovered the largest marine bacterium to date in seawater samples, named “ChoanoVirus”. It can obtain energy from the sun’s rays, has 87,000 bases, has a huge genome, and found 3 types of proteins in its proteins. Rhododendron-This is a light-processing receptor that exists in certain cell membranes in organisms such as the human body.

This latest study shows for the first time that bacteria clearly have the functions of predatory single-celled organisms. Researchers speculate that when organic matter is lacking, whipworm-like organisms will obtain energy through rhodopsin mechanism, or help them accelerate their metabolism.
