Cracking the code of neurodegeneration: New model identifies potential therapeutic target      (via sciencedaily.com)     Original source 

Scientists have developed an innovative neural cell culture model, shedding light on the intricate mechanisms underlying neurodegeneration. Their research pinpointed a misbehaving protein as a promising therapeutic target in the treatment of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD).

Uncovering anxiety: Scientists identify causative pathway and potential cures      (via sciencedaily.com)     Original source 

Quick-acting targeted therapies with minimal side effects are an urgent need for the treatment of anxiety-related disorders. While delta opioid receptor (DOP) agonists have shown 'anxiolytic' or anxiety-reducing effects, their mechanism of action is not well-understood. A new study highlights the role of specific neuronal circuits in the brain involved in the development of anxiety, and distinct mechanisms of action of the therapeutic DOP agonist -- KNT-127.

Air pollution linked to more signs of Alzheimer's in brain      (via sciencedaily.com)     Original source 

People with higher exposure to traffic-related air pollution were more likely to have high amounts of amyloid plaques in their brains associated with Alzheimer's disease after death, according to a new study. Researchers looked at fine particulate matter, PM2.5, which consists of pollutant particles of less than 2.5 microns in diameter suspended in air.

Possible trigger for autoimmune diseases discovered : B cells teach T cells which targets must not be attacked      (via sciencedaily.com)     Original source 

Immune cells must learn not to attack the body itself. A team of researchers has discovered a previously unknown mechanism behind this: other immune cells, the B cells, contribute to the 'training' of the T cells in the thymus gland. If this process fails, autoimmune diseases can develop. The study confirms this for Neuromyelitis optica, a disease similar to Multiple Sclerosis. Other autoimmune diseases may be linked to the failure of this new mechanism as well.

Stress during pregnancy can lead to early maturation of first-born daughters      (via sciencedaily.com)     Original source 

Researchers have found a correlation between early signs of adrenal puberty in first-born daughters and their mothers' having experienced high levels of prenatal stress. They did not find the same result in boys or daughters who were not first-born.

Exposure to Agent Orange damages brain tissue in ways similar to Alzheimer's disease      (via sciencedaily.com)     Original source 

Agent Orange, an herbicide used during the Vietnam War, is a known toxin with wide-ranging health effects. Even though Agent Orange has not been used for decades, there is increasing interest in its effects on the brain health of aging veterans. A new study reveals the mechanisms by which Agent Orange affects the brain and how those processes can lead to neurodegenerative diseases. The research shows that exposures to Agent Orange herbicidal chemicals damage frontal lobe brain tissue of laboratory rats with molecular and biochemical abnormalities that are similar to those found in early-stage Alzheimer's disease.

Neuronal insights: Flash and freeze-fracture      (via sciencedaily.com)     Original source 

Fear and addiction exert significant influence within society. Managing them is often challenging, as they are driven by intricate neuronal circuits in our brains. Understanding the underlying molecular mechanisms is crucial to intervene when these processes malfunction. The novel 'Flash and Freeze-fracture' technique provides a unique glimpse into the respective brain region.

Immune genes are altered in Alzheimer's patients' blood      (via sciencedaily.com)     Original source 

A new study has found the immune system in the blood of Alzheimer's patients is epigenetically altered. That means the patients' behavior or environment has caused changes that affect the way their genes work. Many of these altered immune genes are the same ones that increase an individual's risk for Alzheimer's. Scientists now theorize the cause could be a previous viral infection, environmental pollutants or other lifestyle factors and behaviors.
