Extracellular Vesicles and Cerebral Malaria

Cerebral malaria (CM) remains a major problem of public health at the world level (Idro et al. 2010; WHO 2009), in spite of numerous efforts from various disciplines to improve our knowledge of disease mechanisms (Hunt and Grau 2003; Schofield and Grau 2005; van der Heyde et al. 2006). Our approach to a better understanding of CM pathogenesis has involved the dissection of immunopathological pathways which, in addition to direct changes caused by malaria parasite-infected erythrocytes (IE), lead to neurovascular lesions. We posited that immunopathology is important in CM because a role for cells and soluble mediators of the immune system has been widely recognised as contributing to the complications of viral, bacterial, fungal and many parasitic infections. As detailed earlier, it would be extraordinary if malaria did not conform to this general pattern. As a matter of fact, there now is strong evidence to support immune mechanisms in malarial pathogenesis (Grau and Hunt 2014).Extracellular vesicles (EV) and their subtypes have been described and reviewed by a number of investigators (Hosseini-Beheshti and Grau 2018, 2019; Raposo and Stahl 2019; Witwer et al. 2017; Zijlstra and Di Vizio 2018) and in others chapters of the present book.
