Glial Cell Biology

Meaning

Glial Cell Biology is the study of non-neuronal cells, including astrocytes, oligodendrocytes, and microglia, that reside within the central and peripheral nervous systems and play essential supporting roles. These cells are no longer considered mere “glue” but are recognized as active participants in neurotransmission, brain development, and neuroinflammation, all of which are deeply intertwined with hormonal regulation. In the context of hormonal health, glial cells mediate the effects of circulating hormones on neuronal circuits, impacting mood, cognition, and stress response. Their dynamic interaction with neurons is fundamental to neuroendocrine function and brain health.
