Recent Insights into CD4+ Th Cell Differentiation in Malaria [BRIEF REVIEWS]

CD4+ Th cell differentiation is crucial for protecting against blood-stage Plasmodium parasites, the causative agents of malaria. It has been known for decades that more than one type of Th cell develops during this infection, with early models proposing a biphasic Th1/Th2 model of differentiation. Over the past decade, a large body of research, in particular, reports over the past 2–3 y, have revealed substantial complexity in the Th differentiation program during Plasmodium infection. In this article, we review how several studies employing mouse models of malaria, and recent human studies, have redefined the process of Th differentiation, with a particular focus on Th1 and T follicular helper (Tfh) cells. We review the molecular mechanisms that have been reported to modulate Th1/Tfh differentiation, and propose a model of Th1/Tfh differentiation that accommodates observations from all recent murine and human studies.
