Uncomplicated Plasmodium vivax malaria: mapping the proteome from circulating platelets.

ABSTRACT:

Background

Thrombocytopenia is frequent in Plasmodium vivax malaria but the role of platelets in pathogenesis is unknown. Our study explores the platelet (PLT) proteome from uncomplicated P. vivax patients, to fingerprint molecular pathways related to platelet function. Plasma levels of Platelet factor 4 (PF4/CXCL4) and Von Willebrand factor (VWf), as well as in vitro PLTs-P. vivax infected erythrocytes (Pv-IEs) interactions were also evaluated to explore the PLT response and effect on parasite development.

Methods

A cohort of 48 patients and 25 healthy controls were enrolled. PLTs were purified from 5 patients and 5 healthy controls for Liquid Chromatography-Mass spectrometry (LC-MS/MS) analysis. Plasma levels of PF4/CXCL4 and VWf were measured in all participants. Addition
