Activation of human platelets by misfolded proteins.

OBJECTIVE Protein misfolding diseases result from the deposition of insoluble protein aggregates that often contain fibrils called amyloid. Amyloids are found in Alzheimer disease, atherosclerosis, diabetes mellitus, and systemic amyloidosis, which are diseases where platelet activation might be implicated. METHODS AND RESULTS We induced amyloid properties in 6 unrelated proteins and found th...

Activation of platelets by eosinophil granule proteins

Two of the four principal cationic proteins of the eosinophil granule, major basic protein (MBP) and eosinophil peroxidase (EPO), were shown to be platelet agonists. Both MBP and EPO evoked a dose-dependent nonlytic secretion of platelet 5-hydroxytryptamine in unstirred platelet suspensions even in the presence of 10 microM indomethacin. MBP also evoked secretion of platelet alpha granule and l...

Activation of human platelets by cocaine.

BACKGROUND Cocaine ingestion has been associated with thrombosis of coronary as well as peripheral arteries, but the mechanism by which cocaine promotes thrombus formation is unknown. Accordingly, we determined whether cocaine activates human platelets by flow cytometric analysis of whole blood to which cocaine was added. METHODS AND RESULTS Activated platelets were detected by "two-color" fl...

Activation of human platelets by mastoparan.

Mastoparan is an amphiphilic tetradecapeptide isolated from wasp venom which has been reported to exhibit diverse pharmacological effects in several cell types. These include the activation of phospholipase A, in vitro [l], anticalmodulin activity [2], inhibition of phospholipase C [3], and the ability to promote exocytosis [2!4]Current interest in this agent has arisen -from recent studies dem...

Induction of apoptosis in human tumor cell lines by platelets

Introduction: It has been reported that platelets can eradicate tumor cells in vitro, although the mechanism of this effect has not been determined. The effect of platelets on the induction of apoptosis in tumor cells is largely unknown. Materials and methods: To investigate this effect, two human hematologic cell lines, K562 and Daudi, were independently faced with unstimulated and thromb...
