Research Abstract

It has been reported that malaria parasite infection suppresses host immune system by interfering with the maturation of dendritic cells (DCs) playing a pivotal role in immune responses. However the molecular mechanisms are not well understood. The present study shows that malaria parasite-infected erythrocytes can interact with host bone-marrow cells and cause aberrant differentiation of DCs by suppressing the transcriptional expression of transcription factors IRF4 and IRF8, by using a mouse model of malaria parasite infection.
