ATP

NLRP3 Inflammasome Inducer - Adenosine 5'-triphosphate disodium salt

Adenosine triphosphate (ATP), a potassium efflux agent, can trigger the activation of NLRP3 inflammasome in response to PAMPs, such as LPS and peptidoglycan.

It stimulates the caspase-1-dependent cleavage and secretion of IL-1β from LPS-stimulated cells.

Description

Adenosine triphosphate (ATP), a potassium efflux agent, can trigger the activation of NALP3 inflammasome in response to PAMPs, such as LPS and peptidoglycan.

It stimulates the caspase-1-dependent cleavage and secretion of IL-1β from LPS-stimulated cells [1].

ATP triggers the opening of the non- selective cation channel of the purinergic P2X7 receptor, followed by the gradual opening of a larger pore.

The larger pore is attributed to pannexin-1, which is recruited upon P2X7 receptor activation [2].

Activation of the P2X7 receptor results in potassium efflux which is necessary for activation of the post- translational maturation of IL-1β [3].
