These Researchers Just Discovered a New Cell in the Brain

This new cell found in the brain plays an important role in its functioning. His discovery promises new treatments.

A team of neuroscientists discovered new cell is essential for the functioning brain. A paper recently published in the journal Nature details the role of memory facilitation and motor control. This new set of brain cells also prevents epileptic seizures.

To clarify, this group consists of researchers fromUniversity of Lausanne And Wyss Center for Bio and Neuroengineering.

First, neurons and glial cells

THAT neurons – organized into a giant network in the brain – have remarkable ability to quickly develop and communicate information. The functioning of the brain organ is mainly based on this ability.

THAT glial cells then play a supporting role. In fact, they allow you to perform certain functions. These last structural, energetic, immune and stabilizing. In addition, this cellular assembly covers synapses – points of contact between neurons for diffusion neurotransmitters.

For a long time it was believed that the functioning of the brain depended solely on neurons. and glial cells. Recent Research Shows What They’re Hiding hybrid cell. The latter is actually a mixture of two already known types of brain cells.

New cell of the astrocyte family in the brain

THAT astrocytes are glial cells covering synapses. The authors of the study explored opportunities involving their participation in synaptic transmission. This led to the discovery of a new cell type. Please note that these cells contain similar characteristics to astrocytes.

This similarity is not trivial. The new cell type is actually a subpopulation of astrocytes. Neuroscientists gave it a nameglutamatergic astrocyte. This is due to the ability of this family of cells to produce glutamate which is a neurotransmitter.

On the other hand, the team behind this discovery has demonstrated significant impact glutamate diffusion about synaptic transmission. Glutamatergic astrocytes regulate neuronal activity. Their regulatory function also extends to the level of communication and excitation of neuronal cells.

A decisive discovery in the treatment of Parkinson’s disease and epilepsy

Without this mechanism, memory functioning would be impaired. Note that this observation is true for both humans and mice. By influencing glutamatergic astrocytes, the study authors observed disturbances memory consolidation. There was also an increase in neurological pathologies.

These observations are critical in research to combat diseases such as Parkinson’s disease orepilepsy. A research article mentions that a new cell found in the brain modulates brain circuits associated with the engine control unit.

Thus, glutamatergic astrocytes may become a therapeutic option for the treatment of Parkinson’s disease and epilepsy. According to the World Health Organization, more than 8.5 million people lived with Parkinson’s disease in 2019. The WHO also notes that over the past 2 decades, the prevalence of the disease has doubled.
