High GABA Level Astrocytes Are a New Alzheimer's Disease Biomarker and Drug Target

Cells comprising an abnormal class of brain cells called reactive astrocytes contain high levels of the inhibitory neurotransmitter gamma-aminobutyric acid and are being eyed by researchers as a potential biomarker and drug target for Alzheimer's disease.   More...

Image: Pictured is mouse optic nerve and retina, responsible for relaying information from the eye to the brain. The tissue has been fluorescently stained to reveal the distribution of astrocytes (yellow), retinal ganglion cell axons (purple), myelin (green) and nuclei (cyan). Retinal ganglion cell axons transfer mitochondria to adjacent astrocytes in the optic nerve head behind the retina. Astrocytes degrade the mitochondria in a process called transmitophagy (Photo courtesy of the University of California, San Diego).

Certain Optic Cells Export Their Damaged Mitochondria for Destruction Elsewhere

A recent paper revealed that certain cells in the eye transfer damaged mitochondria to neighboring cells for destruction and recycling.  More...
