Cholecystokinin (CCK) interneurons represent a major population of cortical and hippocampal GABAergic inhibitory neurons characterized by their expression of the cholecystokinin peptide. These cells play crucial roles in regulating neuronal circuits involved in anxiety, memory, food intake, and pain perception. CCK interneurons are particularly vulnerable in neurodegenerative diseases, making them important therapeutic targets.
Cholecystokinin interneurons are a subclass of basket cells that provide powerful perisomatic inhibition to pyramidal neurons. They are distinguished by their expression of CCK, a peptide hormone/neurotransmitter that acts on CCK receptors (CCK1R and CCK2R) throughout the brain["@karson2009"]. These cells are essential for regulating anxiety circuits, memory consolidation, and various cognitive functions["@freund1996"].

Molecular Markers
CCK interneurons can be identified by the following molecular markers:
CCK (cholecystokinin) - primary peptide marker
VIP (vasoactive intestinal peptide) - often co-expressed
CB1R (cannabinoid receptor type 1) - high expression
The study of Cholecystokinin Interneurons has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.
