Astrocytes and Fibroblasts: Hidden in Plain Sight

Astrocytes and fibroblasts are rarely considered in health or disease despite the fact that they are the most numerous cells in the brain and body, respectively. Astrocytes coordinate the workings of the neurons and dictate nervous system responses. They do so chemically rather than electrically. Fibroblasts monitor the status of processes in the body and either act as maintenance cells or mount an inflammatory response in the face of injury or infection. They both function elegantly to protect, maintain and defend balance and health.
