Title:A Neuron cannot shine without astrocytes
Author(s):Lee, Ki Yun
Abstract:How does the single neuron look so outstanding here? Like “Stars can’t shine without darkness” by D.H. Sidebottom, the neuron would not look impressive without its surroundings. In this case, astrocytes are the surroundings, and they are more like supporting roles rather than obstacles. We know exercise can improve cognitive health, but the mechanism is still elusive. My research is to delve into links between them. One of the links to understand neurons is to observe how astrocytes behave. Astrocyte is a type of non-neuronal cell and a key component in neuronal environments to provide energy and regulate factors that can enhance neuronal functionality. Would exercise induces more proliferation and maturation of astrocytes? If so, would more energy and factors be released into neurons, and ultimately would cognitive health be enhanced? The neuron can shine because of astrocytes. Immunofluorescent image from mouse hippocampus. A single neuron is expressed in yellow and astrocytes are expressed in both red and green. However, red specifically indicates fibrillary proteins in astrocytes meaning soma and processes of astrocytes. Whereas green indicates cytoplasmic proteins meaning nuclei. Blue indicates nuclei of all cells regardless of neuronal or non-neuronal cells.
