Key result

Novel P2Y1 antibody EL2Ab inhibits platelet aggregation and delays experimental thrombosis but prolongs bleeding.

Why the study?

Does EL2Ab inhibit platelet function and protect against thrombogenesis in preclinical models?

Population

Platelets and FeCl3-induced thrombosis model

Implication

EL2Ab shows preclinical antithrombotic activity; leaves open P2Y1R as a human therapeutic target pending clinical studies.

Structured PICO

Does EL2Ab inhibit platelet function and protect against thrombogenesis in preclinical models?

P
Population
Platelets and FeCl3-induced thrombosis model
I
Intervention
EL2Ab (novel antibody targeting the second extracellular loop of the P2Y1 receptor)
O
Outcome
Inhibition of ADP-induced platelet aggregation and time for occlusion in a FeCl3-induced thrombosis modelsurrogate

A novel function-blocking antibody against the P2Y1 receptor inhibits platelet aggregation and thrombus formation, validating P2Y1R as a potential target for antiplatelet therapy.

Cite This Study

Karim et al. (2015) studied Thrombosis. EL2Ab (antibody targeting P2Y1R) was evaluated on ADP-induced platelet aggregation and thrombus formation. A novel antibody targeting the P2Y1 receptor (EL2Ab) dose-dependently inhibited ADP-induced platelet aggregation and prolonged occlusion time in a thrombosis model, alongside prolonged bleeding time.
