Motherly Love? Immune System Changes May Play a Role

Changes in the immune system during pregnancy, specifically the decrease of immune cells known as microglia, may contribute to the onset of maternal behavior. Depletion of microglia in female rats, who typically dislike being around offspring, led to accelerated care for newborn rats placed in their cages.

Microglia’s Role in Controlling Anxiety and OCD

A new study reveals how microglia can regulate anxiety and obsessive-compulsive spectrum disorder (OCSD) behaviors. Traditionally overlooked in favor of neurons, specific microglia populations were found to both stimulate and suppress these behaviors, thus acting as both a "brake" and "accelerator".

Unique Microglia Subset Crucial for Cognitive Functioning

A new study discovered not all microglia are the same, challenging existing beliefs. A unique subset of these cells, the ARG1+microglia, important for proper cognitive functions, were identified in mice, with evidence suggesting a similar subset exists in humans.

Human Brain Organoids Reveal How Microglia Develop and Function

Researchers have developed human brain organoids that contain microglia, the immune cells of the brain. These organoids allow researchers to study how microglia develop and function in a more realistic setting than previous models. The researchers found that microglia are influenced by the environment in which they develop, and that they play a role in both development and disease. Their findings could lead to new treatments for neurological disorders.

How Our Brains Turn Into Smarter Disease Fighters

CRISPR gene editing created the G795A amino acid which was introduced to microglia derived from human stem cells. Researchers were able to transplant the donor microglia immune cells into humanized rodent models while administering an FDA-approved cancer drug called pexidartinib. The inclusion of the amino acid cause the donated microglia to thrive and resist the drug, while the host microglia died. The findings open the door for new methods of using microglia to treat a range of neurodegenerative disorders.
