Figure 2. Naturally acquired antibodies to NTS-DBL1α.

Figure 2

A) IgG levels in 134 human plasma samples against the recombinant NTS-DBL1αIt4var60 as detected by ELISA. Non immune indicates 20 non immune Swedish donors. Uncomplicated and severe indicate patients from Cameroon. B) Correlation between patient age and presence of antibodies in the plasma towards the recombinant NTS-DBL1αIt4var60 as measured by ELISA. C) Correlation between ability of the plasma sample to disrupt FCR3S1.2 iRBC rosettes and presence of antibodies towards to NTS-DBL1αIt4var60 as measured by ELISA. D) Correlation between ability of the sample to disrupt FCR3S1.2 iRBC rosettes and patient age. E) Correlation between ability of the plasma sample to recognize FCR3S1.2 iRBC surface as detected by FACS and presence of antibodies towards to NTS-DBL1αIt4var60 as measured by ELISA. F) Correlation between ability of the plasma sample to recognize FCR3S1.2 iRBC surface as detected by FACS and patient age.
