Abstract
Glycogen Synthase Kinase-3β (GSK-3β) is a multifunctional serine/threonine kinase involved in the regulation of glucose metabolism, immune signaling, and inflammatory responses. While its roles in neurodegenerative diseases and oncology are well established, emerging evidence suggests a critical function in hematopoiesis and platelet biology. In malaria, platelets exhibit a dual role: they contribute to parasite clearance through the release of Platelet Factor 4 (PF4), yet also promote microvascular sequestration implicated in cerebral malaria (CM). We hypothesize that pharmacological inhibition of GSK-3β provides a multi-dimensional therapeutic benefit by enhancing platelet-mediated parasite killing, modulating macrophage polarization, and directly targeting the parasite’s orthologous kinase, PfGSK-3. Furthermore, we propose that PF4 secretion may serve as a functional indicator of suppressed GSK-3β signaling in platelets. Importantly, we further propose that GSK-3β inhibition biases platelet function toward antimicrobial degranulation rather than adhesion-mediated sequestration, thereby enhancing host defense while mitigating cerebral complications. This host-directed therapeutic strategy offers a promising framework to combat the erythrocytic stage of malaria while reducing its severe neurological outcomes.
