ThapaFIGURE 2 Histogram representation of Phycoerrythtrin (PE)-labeled annexin-V binding to PMPsKathmandu University/Birat Medical School Teaching Hospital,Conclusions: Our findings suggested that PrP(10626) induced 30fold rise in intracellular rise in calcium. It was attributable to influx from extracellular fluid. Calcium mobilization was associate with 80 fold stimulation in action of thiol protease that laid to partial cleavage of cytoskeleton-associated protein talin and in depth shedding of platelet-derived microparticles. The two proteolysis of talin and microparticle release have been precluded by calpeptin i.e., a specific inhibitor of calpain. As microparticles are endowed with phoshpatidylserine (PS)-enriched surface and so are procoagulant in nature, exposure to prion favors thrombogenic state.Biratnagar, Nepal; Damak Hospital Investigation Center, Damak, Nepal;Nirnayak Reference Lab Damak, Damak, NepalBackground: The amino acid sequence 10626 of prion proteins i.e., PrP(10626) is highly amyloidogenic. It leads to prion-mediated pathologies. As PrP(10626) is identified for being expressed in blood following leakage from brain tissue in prion illnesses, we aimed to investigate the modalities of its pathological effects in human platelets. Aims: We aimed to investigate: 1. Calpain activity two. Facilitation of talin degradation three. Shedding of Platelet-derived microparticles (PMPs). Methods: one. Isolation of human blood platelets in resting state by differential centrifugation two.
