P2RY13 (Purinergic Receptor P2Y13) is a G protein-coupled receptor that belongs to the P2Y receptor family, which responds to extracellular nucleotides. Located on chromosome 3q25.2, P2RY13 is primarily expressed in immune cells, including microglia in the brain, where it plays a crucial role in modulating inflammatory responses. The receptor responds to extracellular ATP and ADP, triggering signaling cascades that influence microglial phagocytosis, cytokine release, and neuroinflammation. In the nervous system, P2RY13 mediates neuron-glia communication and contributes to neuroinflammatory processes underlying various neurodegenerative diseases, making it a potential therapeutic target.
P2RY13 (Purinergic Receptor P2Y13) is a G protein-coupled receptor that responds to extracellular nucleotides, particularly ATP and ADP. P2RY13 is expressed primarily in immune cells, including microglia in the brain, where it plays a role in modulating inflammatory responses. Activation of P2RY13 can influence microglial phagocytosis, cytokine release, and neuroinflammation. In the nervous system, P2RY13 is involved in neuron-glia communication and may contribute to the neuroinflammatory processes that underlie various neurodegenerative diseases.
P2RY13 is highly expressed in immune tissues and in the brain, particularly in microglia. It is also expressed in astrocytes and neurons at lower levels.
