Our analysis showed that the capacity of innate responses to restrict initial parasite growth saturates with parasite dose and that experimentally enhanced innate immunity can affect parasite density indirectly via resource depletion.

Drawing on data from mice, they present a new statistical approach to analyzing how parasitemia changes over time and to quantifying and comparing the roles played by the immune system and the availability of red blood cells in regulating parasite numbers.

Signalling through the IL-2 receptor [gamma]c peptide (CD132) is essential for the expression of immunity to Plasmodium chabaudi adami blood-stage malaria (pages 512–516)

A genetic dissection approach was employed to determine whether the IL-2 receptor complex (IL-2R) comprised of α, β and γ chains is required for the suppression of Plasmodium chabaudi adami parasitemia.

Recombinant Plasmodium falciparum merozoite surface protein 3 (PfMSP3F) and a 24-kDa fragment from its N terminus (MSP3N) that includes the essential conserved domain, which elicits the maximum antibody (Ab)-dependent cellular inhibition (ADCI), were expressed as soluble proteins in Escherichia coli. Both proteins were found to be stable in both soluble and lyophilized forms.
