Image 1. Nestin-positive radial glia in the developing spinal cord. Nestin (green) labels radial glial processes in the dorsal ventricular zone of the embryonic mouse spinal cord. A subset of dorsal progenitors is shown in red and nuclei in blue.

Image 2. "The Astros through my Kaleidoscope" A mirrored immunostained human hippocampus section from a multiple sclerosis patient reveals the subsequent reactivity of astrocytes, their polarization towards a lesion, and the loss of GLT1 localization. Like bright beams of light from stars in the inky night sky, the vibrant green astrocytes project their intricate processes to communicate, guide, and provide support to damaged structures. Even if they lose a piece of themselves along the way.

Image 3. 'Sentinels of the Synapse' Phase contrast micrograph of primary Bergmann glia cells (BGCs) isolated from chick cerebellum. The characteristic stellate morphology with extensive process arborization reflects the remarkable structural adaptability of these specialized astrocytes, whose glutamate transporter expression (GLAST/EAAT1) is dynamically regulated, protecting neurons from excitotoxicity. These cells seemingly quiet sentinels under the microscope are the cerebellum's frontline defenders of synaptic homeostasis.

Image 11. "Gateways into the Brain" - A three-dimensional rendering of astrocytes and their gap junction connections surrounding a brain blood vessel. The orange structures are the GFAP cytoskeleton of the astrocytes with the gap junctions connecting them in purple. Nuclei of all cells (including vascular endothelial cells along the vessel) are shown in blue. Astrocyte extend endfeet to encase the vessel with larger gap junctions connecting endfeet. Rat brain imaged on a Zeiss 980 Airyscan 2 confocal microscope with 1.4NA 63X objective at the NYIT Imaging Center. Image rendered with Comet ORS Dragonfly software. Astrocytes, their gap junctions, and their perivascular endfeet are critical for controlling distribution of chemicals into and across the brain- dysfunction of these parts can occur in aging and brain injury.

Image 14. This image captures the hippocampus, the brain's memory hub, as a vibrant garden in red and green. The red glow highlights NeuN, marking neuron cell bodies, while green reveals NF-M, tracing their branching connections. Together, these patterns show the delicate network that supports learning and memory. My research explores how reducing calcium activity in neighbouring support cells, called astrocytes, can influence neurons and other brain cells, revealing how subtle cellular signals shape the health and function of memory circuits.
