Brain Cells That Enhance Memory Focus and Storage Identified

Researchers uncovered how certain brain cells enhance our ability to maintain and focus on short-term memories. Their study highlights a new type of neuron, dubbed PAC neurons, which coordinate the activity of memory-specific neurons without storing any information themselves.

Lecanemab Alzheimer’s Treatment Set for FDA Approval

Doctors are preparing to administer lecanemab, a promising new Alzheimer's disease treatment nearing FDA approval. This therapy, marketed as Leqembi, slows cognitive decline by extracting amyloid proteins from the brain, thus decreasing tau protein accumulation.

Eye Blood Vessel Changes: A New Window into Alzheimer’s Diagnosis

Abnormalities in eye blood vessels could provide early diagnosis of Alzheimer's disease. By comparing blood vessels in retinas from Alzheimer's patients, individuals with mild cognitive impairment, and healthy subjects, the team discovered a disruption in the blood-retinal barrier, which prevents harmful substances from entering the retinal tissue.

Engineered Cells Offer Promise for Treating ALS and Blinding Diseases

Engineered stem cells may lead to personalized treatments for a range of neurological and visual disorders, a new study reports. Transplanting engineered induced pluripotent stem cells into the eyes of rodents with retinal degeneration led to the protection of cells in the eyes that support vision. In ALS models, transplanting cells into the spinal cord protected movement controlling cells. The engineered cells also created astrocytes and did not result in tumor formation.

Changes in the Brain Responsible for Motor Skill Learning

As rat models became proficient at learning new motor skills, they developed synchronous low-frequency oscillatory activity in two brain areas that were recorded that emerged across the cerebellum and motor cortex networks with skill consolidation.

Large-Scale Generation of Muscle-Controlling Nerve Cells From ALS Patients

A person's sex is one of the main drivers of altered gene expression in motor neurons, regardless of whether they were derived from patients diagnosed with ALS. Male ALS stem cells generated significantly more motor neurons than the control group, however, this was not seen in female samples.

Gut Bacteria May Play a Role in Diabetes

People with higher levels of the gut bacteria Coprococcus tend to have higher insulin sensitivity, while those with higher levels of Flavonifractor have lower levels of insulin sensitivity. Researchers say specific gut bacteria could play a significant role in the development of Type 2 diabetes.
