Central nervous system cells (CNS cells) (CNS cells)

Central nervous system (CNS) cells consist of neurons and various types of glial cells, such as astrocytes, oligodendrocytes, and microglia, which together form the functional architecture of the brain and spinal cord [1, 2]. These cells are responsible for the transmission and processing of electrical and chemical signals that govern all bodily functions, from basic reflexes to complex cognition [2]. In the context of drug discovery, 'central nervous system cells' is considered a broad tissue or cellular category rather than a specific molecular target like a receptor or enzyme [3]. Pharmacological interventions typically aim at specific proteins expressed by these cells, such as ion channels, G protein-coupled receptors, or transporters, to modulate neural activity or provide neuroprotection [3]. Pathological changes in CNS cells, including neuronal loss or glial activation, are hallmarks of neurodegenerative diseases like Alzheimer's and Parkinson's disease [2]. Developing drugs that affect CNS cells requires overcoming the blood-brain barrier and minimizing off-target effects that could lead to significant cognitive or motor impairment [3, 4, 5].

Drugs do not target central nervous system cells as a single entity; instead, they interact with specific molecular targets such as G protein-coupled receptors, ion channels, enzymes, and transporters expressed by these cells to modulate neural signaling, metabolism, or survival.
