ATPergic signalling during seizures and epilepsy.

Area of Science:

• Neuroscience
• Pharmacology
• Cell Biology

Background:

• Despite advances in anti-epileptic drugs (AEDs), 30% of epilepsy patients have poor seizure control.
• Neuroinflammation and glial cell interplay at the tripartite synapse are increasingly recognized as drivers of epileptogenesis.
• ATP-gated purinergic receptors (P2Rs) on neurons and glia are crucial in brain function and pathology.

Purpose of the Study:

• To review the role of ATP-mediated signaling in seizures.
• To summarize the functional impact of targeting P2Rs on seizure control and associated pathology.
• To highlight P2Rs as potential therapeutic targets for epilepsy.

Main Methods:

• Literature review of studies on ATP signaling and P2R function in seizures.
• Focus on P2X7, P2X4, and P2Y12 receptor subtypes.
• Analysis of research in animal models of acute seizures and epilepsy.

Main Results:

• Pharmacological targeting of P2Rs can modulate seizure generation and neuroinflammation.
• P2X7, P2X4, and P2Y12 receptors are implicated in seizure-related pathological processes.
• Previous research primarily focused on expressional changes of P2Rs in epilepsy.

Conclusions:

• Targeting P2Rs presents a promising strategy for novel anti-epileptic therapies.
• Modulating P2Rs may address seizure control and reduce seizure-induced brain damage.
• Further research into P2R function is warranted for drug development.
