New research has now described precisely how this works. The scientists show that cold can prevent the pathological aggregation of proteins typical for two aging-associated neurodegenerative diseases.

They believe neurodegeneration of one of these populations leads to motor impairments, while damage to the other population, located in a structure called the striosome, may account for the mood disorders that are often see in the early stages of the disease.

This housekeeping is significant in Huntington's because a buildup of waste in a specific kind of neuron leads to such cells' untimely deaths. The researchers also showed that enhancing the autophagy pathway in such neurons that were created from skin cells of Huntington's patients protects those cells from dying.

The new study expands our understanding of the underlying mechanisms of the disease, and reinforces the potential of therapies that target glia cells.

Now, scientists have found that the cells have the mechanisms to clear those aggregates -- they just fail to activate them.

They also found significant differences between healthy cells and those from Huntington's disease patients.

However, research so far has mainly focused on movement impairment, a symptom associated with the more advanced stages of the disease. A new study now shows that the emotional brain - the limbic system - is affected earlier in the course of the disease, and should therefore be given more attention in the development of new treatments. Tue, 07 Sep 2021 16:06:28 EDT //www.koonmotors.com/releases/2021/09/210907160628.htm //www.koonmotors.com/releases/2021/08/210819102709.htm Proteins are the 'tools' of our cells – they are essential to all vital tasks. However, they are only able to do their jobs if they fold correctly and adopt their respective, very specific 3D structure. To ensure that nothing goes wrong with the folding process, it is strictly monitored in the cell. The consequences of a flawed quality control can be seen, for example, in the deposition of misfolded proteins in neurodegenerative diseases such as Alzheimer's. Researchers have now developed a mouse line that makes the state of protein balance visible in the mammalian brain for the first time. In this way, the processes of protein quality control can now be studied in healthy and diseased neurons in more detail.

The 'Geomic' approach can be applied to other diseases, authors say.

This large, international project opens a potentially new avenue for diagnosing and treating some individuals with FTD or ALS.

With the anticipated arrival of preventive gene therapies that will most likely be administered to young children known to be carriers of the HD mutation, it is crucial to have a means to evaluate motor abilities in children that is sensitive to the child's stage of development.

Understanding the ''why'' matters as new clinical trials testing therapies for people who haven't yet developed symptoms of Huntington disease requires participants to be tested for the HD gene to be included in the trials.

Now, scientists have discovered that sensory signals in the brain's cerebral cortex, which plays a key role in controlling movement and other functions, have a different pattern of connections between nerve cells and different effects on behavior than motor signals. The motor area of the cortex sends signals to stimulate muscles.

Scientists have discovered why Huntington's is so toxic to cancer cells and harnessed it for a novel approach to treat cancer, a new study reports.

The resulting mass of neurons serves as a new tool to study the degenerative and eventually fatal neurological condition, according to the researchers.
