Trends in Parasitology: The Biology and Pathogenesis of Vivax Malaria

Jun 26, 2026

Upload by Jiven

Plasmodium vivax drives substantial global malaria morbidity and has benefited from recent advances in invasion biology, hypnozoite mechanisms, and experimental modeling. Progress includes identifying pathways for merozoite invasion of nascent reticulocytes and improving understanding of hypnozoite biology through humanized mouse models and hepatocyte culture systems. The spleen is highlighted as a major reservoir via an endosplenic asexual life cycle, linked to recurrent chronic infection, systemic inflammation, anemia, and organ dysfunction. Despite gains, mechanisms and comorbid roles remain incomplete, affecting prevention and elimination strategies.

FAQs

What major biological advances are highlighted for P. vivax invasion and vaccine development?

The review highlights discovery of pathways that facilitate invasion of P. vivax merozoites into nascent reticulocytes, which is relevant to vaccine development.

How do hypnozoites and experimental models contribute to understanding P. vivax biology?

Humanized mouse models and hepatocyte culture systems are described as improving understanding of hypnozoite biology, while relapse from latent hypnozoites remains a defining feature.

Why is the spleen emphasized in P. vivax malaria and anemia?

The spleen is presented as a major reservoir for asexual vivax parasites via an endosplenic life cycle, contributing to recurrent chronic infections, systemic inflammation, and anemia; splenic accumulation of uninfected red cells is identified as the predominant cause of anemia.
