WebNov 20, 2009 · ADP in turn triggers the second, P2Y12-dependent wave of Rap1-mediated signaling events, leading to the sustained activation of integrins and further release of TxA2. Higher concentrations of GPVI agonists lead to the concomitant activation of CalDAG-GEFI and PKC, facilitating platelet aggregation independent of feedback by endogenous TxA2. WebMar 1, 2014 · The primary wave of aggregation reflects response to the addition of exogenous agonist. When normal platelets are activated, they secrete an endogenous pool of agonists. The secondary wave represents aggregation in response to this … The Next Wave of T-cell Engagement for the Management of Diffuse Large B-cell …

WebThe PFA is a screening test for platelet dysfunction. The cartridge membrane is coated with collagen, and with one of two platelet agonists (epinephrine or ADP). The platelets adhere to the collagen and aggregate in response to the collagen and epinephrine (or ADP).
