A specialized type of immune cell that may help explain why malaria kills some people and not others has been identified by Australian researchers.
Their study of 33 malaria-infected adults in Indonesia found high levels of highly suppressive regulatory T-cells in the blood of those with severe malaria but not in those who weren't as sick, the Associated Press reported.
The findings were published in the journal PLoS Pathogens. The next step is to determine whether these immune cells actually cause more severe malaria or are caused by having a severe case of the disease.
"Our results indicate that severe malaria is accompanied by the induction of highly suppressive T-reg cells that can promote parasite growth," said lead researcher Magdalena Plebanski, of Monash University, the AP reported. Vaccine studies should carefully examine whether recipients develop this type of immune reaction, Plebanski suggested.
