The sequestration of pRBCs to the EC through the sur face adhesion receptors is crucial to CM, since this directly affects BBB structure and function. This process is known to occur mainly through interactions ABT-737 分子量 between the P. falciparum protein PfEMP1 and human proteins present on endothelial cells. PfEMP1 presentation is thus a key event in the sequestration process. Though KAHRP and ETRAMP are crucial in PfEMP1 presentation, the effect of temperature on the trafficking of these proteins by PfHsps is not fully understood. This work links inter actions involving a set of PfHsps that might play a crucial role in the trafficking of ETRAMP and KAHRP to increased PfEMP1 presentation on the pRBCs. In CM, the effect of temperature in the trafficking of PfEMP1 to pRBC surface has been well studied.<br><br> Although anti pyretics have been associated with reduced parasite clearance, the use of antipyretics in CM AEB071 臨床試験 afflicted patients is largely seen as protective. This is attrib uted to decreased cytoadherence at lower body tempera ture, which assists anti malarial drugs in clearing ring stage parasites before they mature and cytoadhere. Fur ther experimental work is necessary to study if this is due to the effect of antipyretics on the trafficking of ETRAMP and KAHRP resulting in decreased PfEMP1 presentation. Activated platelets act as bridges between pRBCs and endothelial cells, allowing the binding of pRBC to the endothelium devoid of cytoadherence receptors. The MSP 1 gpIIIa interaction might play a crucial role in platelet activation, either via complex formation with MSP 6MSP 7 or through contact with pRBCs, thus influencing systemic inflammation in CM.<br><br> Antibody mediated blocking of the activity of gpIIb IIIa in vitro has revealed decreased platelet activation. Other studies also show lowered antibody response to MSP 1MSP 6 MSP 7 in CM patients when compared with non affected patients. AG-014699 構造 Lowered antibody response to GPI anchor has also been reported in CM non survivors when com pared to the CM survivors. Hence, the MSP 1 gpIIIa interaction could indicate a novel mechanism of platelet activation by MSP 1. Platelet activation is also associated with tissue factor expression on the platelet surface. TF expression leads to amplification of the coagula tion cascade resulting in the consumption of coagulation factors.<br><br> Platelet activation via MSP 1 and gpIIIa might thus also play a role in TF expression on the platelet sur face causing amplification of the coagulation cascade, leading to haemostasis dysfunction. Haemostasis dysfunction during CM culminates in increased endothelial hemorrhage resulting in leakage of plasma proteins, proinflammatory cytokines and parasite factors across the BBB. This influx of foreign substances activates the microglial cells, resident macrophages of the brain and spinal cord. Upon activation, they release proinflammatory cytokines which damage astrocytes and glial cells that are crucial for BBB maintenance. In addition to the damage caused by this cytotoxic environ ment, it was hypothesized that the interaction between HSA and the TGF B receptors TGFBR1 and TGFBR2 could result in astrocyte dysfunction, followed by sei zures and neuronal death.
