Malaria associated anemia is increasingly recognized as a consequence not only of red cell destruction but of profound, parasite driven disruption of erythropoiesis within the bone marrow niche. Here, we synthesize recent in vitro, ex vivo, clinical and postmortem studies to construct a unified mechanistic framework in which four interlocking pathways converge to produce dyserythropoiesis. First, a cytokine storm dominated by IL-6, TNF-α, IFN-γ and MIF suppresses erythropoietin synthesis, upregulates hepcidin and diverts erythroid progenitors toward myeloid fate via destabilization of GATA-1. Second, hemozoin crystals catalyze Fenton chemistry and lipid peroxidation, generating 4-hydroxynonenal adducts that cripple GATA-1 and trigger mitochondrial apoptosis of erythroblasts. Third, Plasmodium parasites preferentially infect orthochromatic erythroblasts, prolonging a 10-day gametocyte maturation cycle beyond the host's 3-4-day enucleation window and releasing extracellular vesicles that arrest terminal differentiation. Fourth, hemozoin-laden macrophages remodel erythroblastic islands, precipitating local iron restriction and sustained oxidative stress. Together these processes create a "developmental sanctuary" that favors parasite persistence while crippling host erythropoiesis. We also highlight emerging single-cell and spatial-omics technologies, together with 3-D bone-marrow organoids, as platforms for dissecting spatiotemporal parasite-host interactions and for testing niche-targeted therapies aimed at reversing ineffective erythropoiesis.
期刊介绍:
Frontiers in Cellular and Infection Microbiology is a leading specialty journal, publishing rigorously peer-reviewed research across all pathogenic microorganisms and their interaction with their hosts. Chief Editor Yousef Abu Kwaik, University of Louisville is supported by an outstanding Editorial Board of international experts. This multidisciplinary open-access journal is at the forefront of disseminating and communicating scientific knowledge and impactful discoveries to researchers, academics, clinicians and the public worldwide.
Frontiers in Cellular and Infection Microbiology includes research on bacteria, fungi, parasites, viruses, endosymbionts, prions and all microbial pathogens as well as the microbiota and its effect on health and disease in various hosts. The research approaches include molecular microbiology, cellular microbiology, gene regulation, proteomics, signal transduction, pathogenic evolution, genomics, structural biology, and virulence factors as well as model hosts. Areas of research to counteract infectious agents by the host include the host innate and adaptive immune responses as well as metabolic restrictions to various pathogenic microorganisms, vaccine design and development against various pathogenic microorganisms, and the mechanisms of antibiotic resistance and its countermeasures.
