“…Point (3) for the cytokine hypothesis is questionable with some studies showing a clear increase in TNF in CM, which is even higher in fatal cases in African children (Grau et al, 1989; Kwiatkowski et al, 1990; Sahu et al, 2013), but more recent studies have shown no correlation between TNF concentration and CM (Esamai et al, 2003; Armah et al, 2007; Thuma et al, 2011). Other cytokines have been implicated too (Hunt and Grau, 2003; Boeuf et al, 2012; Ioannidis et al, 2014), but the results of these studies are hard to interpret as it depends on which control group it is compared to; NCM, severe malarial anemia, other encephalitis, other febrile illnesses or even healthy individuals.…”

“…Soluble ICAM-1 does seem to correlate with CM (Adukpo et al, 2013), but depending on the comparator control group (UM or other SM) it seems more strongly associated with SM (Cserti-Gazdewich et al, 2010; Erdman et al, 2011). Circulating endothelial microparticles are also associated with SM only in adults (Sahu et al, 2013) but do correlate with CM in children (Combes et al, 2004). …”

Despite decades of research on cerebral malaria (CM) there is still a paucity of knowledge about what actual causes CM and why certain people develop it. Although sequestration of P. falciparum infected red blood cells has been linked to pathology, it is still not clear if this is directly or solely responsible for this clinical syndrome. Recent data have suggested that a combination of parasite variant types, mainly defined by the variant surface antigen, P. falciparum erythrocyte membrane protein 1 (PfEMP1), its receptors, coagulation and host endothelial cell activation (or inflammation) are equally important. This makes CM a multi-factorial disease and a challenge to unravel its causes to decrease its detrimental impact.

“…MPs derived from iRBCs are more potent in activating macrophages than iRBCs, an effect mediated by TLR4 and MyD88-signalling (Couper et al 2010). These circulating MPs are highly associated with CM in both humans and mice (Combes et al 2005;Pankoui Mfonkeu et al 2010;Sahu et al 2013). MPs produced by other cell types including ECs, leukocytes and platelets, are also implicated in malaria pathology but will be discussed later (see Section 'Inflammation').…”

One sentence summary: The intricate balance between anti-malarial immunity and parasite virulence factors including immune evasion mechanisms determine the outcome of malaria infections, as imbalances resulting in exaggerated parasite growth, excessive inflammation or the combination of both result in severe pathology. Editor: Christian van Ooij ABSTRACTCoevolution of humans and malaria parasites has generated an intricate balance between the immune system of the host and virulence factors of the parasite, equilibrating maximal parasite transmission with limited host damage. Focusing on the blood stage of the disease, we discuss how the balance between anti-parasite immunity versus immunomodulatory and evasion mechanisms of the parasite may result in parasite clearance or chronic infection without major symptoms, whereas imbalances characterized by excessive parasite growth, exaggerated immune reactions or a combination of both cause severe pathology and death, which is detrimental for both parasite and host. A thorough understanding of the immunological balance of malaria and its relation to other physiological balances in the body is of crucial importance for developing effective interventions to reduce malaria-related morbidity and to diminish fatal outcomes due to severe complications. Therefore, we discuss in this review the detailed mechanisms of anti-malarial immunity, parasite virulence factors including immune evasion mechanisms and pathogenesis. Furthermore, we propose a comprehensive classification of malaria complications according to the different types of imbalances.
