Fetal Immunity Defends the Brain Before Birth

New research reveals that fetuses can mount immune responses against infections long before birth, challenging the assumption that they rely solely on maternal immunity. A study on Zika virus infections found that immune cells like microglia protect the developing brain, while others, like monocytes, can cause damaging inflammation.

SUMO Proteins Trigger Brain Stem Cell Reactivation for Repair

SUMO proteins play a key role in activating dormant neural stem cells, vital for brain repair and regeneration. This finding, centered on a process called SUMOylation, reveals how neural stem cells can be "woken up" to aid in brain recovery, offering potential treatments for neurodegenerative diseases.

Unique Omega-3 Fatty Acid Lipid Could Revolutionize Our Understanding of Brain Development and Aging

Researchers identified a special transporter protein, Mfsd2a, that plays a critical role in regulating the brain cells responsible for protecting nerves with myelin sheaths. Loss of myelin sheaths can occur during the normal aging process and in neurological diseases such as multiple sclerosis and Alzheimer's disease. Findings indicate LPC omega-3 lipids can direct oligodendrocyte development, a process that is critical for brain myelination.

Possible link between autism and antidepressants use during pregnancy: Mouse Study

A new study in mice reveals a possible link between the use of SSRI antidepressants during pregnancy and an increased risk of autism-like symptoms in offspring. Offspring exposed to fluoxetine (Prozac) in utero were more likely to exhibit impaired neurotransmission caused by an overactive serotonin receptor in the prefrontal cortex, an area of the brain implicated in modulating social behaviors. However, treating the mice with a compound that blocks the receptor alleviated the behavioral problems and improved working memory.
