Microglia Might Lessen Seizure Severity in Epilepsy
Article title: Microglia depletion exacerbates acute seizures and hippocampal neuronal degeneration in mouse models of epilepsy Authors: Mei Liu, Lijuan Jiang, Min Wen, Yue Ke, Xiangzhen Tong, Weiyuan Huang, Rongqing Chen From the authors: “Our study indicates that microglia are innately ready…
The Novel Role of Microglia as Modulators of Neurons in the Brain Is Discovered by Mount Sinai Researchers
Findings offer potential target for treating behavioral abnormalities associated with neurodegenerative conditions like Alzheimer’s Disease
Brain’s Immune Cells Promising Cellular Target for Therapeutics
Inspired by the need for new and better therapies for neurodegenerative diseases, Rutgers University researchers are exploring the link between uncontrolled inflammation within the brain and the brain’s immune cells, known as microglia, which are emerging as a promising cellular target because of the prominent role they play in brain inflammation. In APL Bioengineering, the group highlights the design considerations and benefits of creating therapeutic nanoparticles for carrying pharmacological factors directly to the sites of the microglia.
Strokes in babies are surprisingly common. Here’s how the body rushes to the rescue.
New research is shedding light on the development of the brain’s immune defenses – and how those defenses respond to strokes that strike one in 4,000 babies in the first month of life.
Microglia Might Lessen Seizure Severity in Epilepsy
New research in mice highlights the potential protective effect of microglia—a type of non-neuronal cell in the brain—against overactivation of the central nervous system during acute epileptic seizures. The study is published in the American Journal of Physiology-Cell Physiology.
Researchers Identify a Protein That Is Critical for Wound Healing after a Central Nervous System Injury
after a Central Nervous System Injury
(New York – March 2, 2020) Plexin-B2, an axon guidance protein in the central nervous system (CNS), plays an important role in wound healing and neural repair following spinal cord injury (SCI), according to research conducted at the Icahn School of Medicine at Mount Sinai and published today in Nature Neuroscience.
Flickering Light Mobilizes Brain Chemistry That May Fight Alzheimer’s
The promise of flickering light to treat Alzheimer’s takes another step forward in this new study, which reveals stark biochemical mechanisms: The 40 Hertz stimulation triggers a marked release of signaling chemicals.
Genetic Variation in Individual Brain Cell Types May Predict Disease Risk
Researchers identified non-coding regions of the human genome that control the development and function of four brain cell types and mapped genetic risk variants for psychiatric diseases. They found that risk variants for Alzheimer’s disease were enriched in microglia-specific regulatory elements.
Scientists discover link between unique brain cells and OCD and anxiety
Scientists discovered a new lineage of specialized brain cells, called Hoxb8-lineage microglia, and established a link between the lineage and OCD and anxiety in mice. Their experiments proved that Hoxb8-lineage microglia prevent mice from displaying OCD behaviors and sex hormones drove symptom severity and anxiety.
Link between brain immune cells and Alzheimer’s disease development identified
Irvine, Calif., Aug. 21, 2019 — Scientists from the University of California, Irvine School of Biological Sciences have discovered how to forestall Alzheimer’s disease in a laboratory setting, a finding that could one day help in devising targeted drugs that prevent it. The researchers found that by removing brain immune cells known as microglia from rodent models of Alzheimer’s disease, beta-amyloid plaques – the hallmark pathology of AD – never formed.
Alzheimer’s missing link ID’d, answering what tips brain’s decline
Brain’s immune cells form nexus between two damaging Alzheimer’s proteins Years before symptoms of Alzheimer’s disease appear, two kinds of damaging proteins silently collect in the brain: amyloid beta and tau. Clumps of amyloid accumulate first, but tau is particularly…
