The overall research goal of the Bunnik laboratory is to understand the development and maintenance of protective antibody responses in malaria-experienced individuals and to use this knowledge towards the design of a novel, effective malaria vaccine. To identify targets of protective anti-malaria humoral immunity, we screen and clone antibodies from protected individuals living in malaria-endemic regions, followed by further characterization of antibodies reactive against the malaria parasite.

In addition, we study the development of B cells responses to Plasmodium falciparum infection. Using high-parameter flow cytometry and single-cell sequencing, we aim to better understand how B cells respond to different antigens and which B cell responses underlie long-lived immunological memory. Using B cell receptor (BCR) sequencing to track clonally related cells, we investigate the development and differentiation pathways of B cells in Plasmodium-exposed individuals. 

An additional focus of the lab is the regulation of gene expression in the malaria parasite, Plasmodium falciparum, by epigenetic, transcriptional, and post-transcriptional mechanisms

  • Research & Grants

    Research in the Bunnik Lab is aimed at understanding the nature and the development of protective immune responses to malaria, with the overall goal to design an effective malaria vaccine. In endemic regions, malaria exposure results in an immune response that protects against clinical disease. However, this protective immunity takes years to develop, leaving children highly susceptible to severe disease and death. A better understanding of this immunological protection will facilitate malaria vaccine development. Our approach to increasing our knowledge about protective immune responses is to learn from nature, i.e. to study immune responses elicited as a result of natural infection.
