Mice and rabbits immunized with recombinant forms of malaria vaccine candidate antigens rhoptry-associated proteins 1 and 2 (RAP-1, RAP-2 and rRAP-1, rRAP-2) produce antibodies at titres equivalent to monoclonal antibody ascites fluid raised against the native proteins.

We previously demonstrated that a panel of antigen-specific T helper cell clones derived from B. bigemina RAP-1-immunized cattle expressed relatively high levels of interferon-gamma (IFN-gamma) protein and transcript and low levels of interleukin-4 (IL-4), indicative of a type 1 immune response.

In the current study we present evidence that subcutaneous immunization with native B. bigemina RAP-1 protein in RIBI adjuvant induces a predominant type 1 immune response in vivo, characterized by relatively high levels of IFN-gamma and IL-2 and low levels of IL-4 and IL-10 mRNA in the draining prescapular lymph node.

|
Ex vivo restimulation of draining lymph node lymphocytes with specific antigen resulted in proliferation and enhanced expression of IL-2 and IFN-gamma, whereas IL-4 and IL-10 transcript levels remained relatively low.

Naturally occurring antibody responses to Plasmodium falciparum rhoptry-associated proteins 1 and 2 (RAP-1 and RAP-2) were measured with recombinant and parasite-derived forms of the antigens.

Eighty-six and 82% of individuals over 30 years of age had antibodies that recognized parasite-derived RAP-1 and RAP-2, respectively.

The recognition of RAP-1 and RAP-2 correlated with age and with the recognition of recombinant forms of the ring-infected erythrocyte surface antigen, merozoite surface protein 1, and merozoite surface antigen 2 (MSA2) antigens.

Th1-like clones responding to these epitopes proliferated differentially to different strains of B. bigemina, raising the possibilities that the T-cell epitopes may vary antigenically and that CT-1 may be differentially expressed with respect to the other RAP-1 CT domains in the different strains.

Consistent with this were the distinct subcellular localizations of RAP1 and 2 in disrupted RAP1 parasites, where RAP2 does not traffic to the rhoptries but is instead located in a compartment that appears related to the lumen of the endoplasmic reticulum.

To define the location of CD4(+)-T-cell epitopes for vaccine development using a recombinant protein or minigene construct, a series of truncated recombinant RAP-1 proteins and peptides were tested for stimulation of T-cell lines derived from B. bovis-immune cattle.

Plasmodium falciparum rhoptry-associated proteins 1 (RAP1) and 2 (RAP2) are antigens presenting themselves as candidates for a subunit malaria vaccine.

HABPs inhibited in vitro merozoite invasion by between 54% and 94% at 200 microM, suggesting that these RAP2 peptides are involved in the in vitro P. falciparum invasion process.

Human leukocyte antigen class II alleles influence levels of antibodies to the Plasmodium falciparum asexual-stage apical membrane antigen 1 but not to merozoite surface antigen 2 and merozoite surface protein 1.
|

|
This association for AMA1, combined with the previously reported association between HLA class II alleles and levels of antibodies to rhoptry-associated protein 1 (RAP1) and RAP2, indicates that HLA influences the levels of antibodies to three of the five vaccine candidate antigens that we have evaluated.

Five high activity binding peptides (HABPs) were identified; 26201, 26202, 26203 and 26204 spanned residues 461C-K540 within RAP1 Cys region, whilst 26188 (201T-Y220) was located in p67 amino terminal.

Considering the promising results obtained in previous trials by immunizing monkeys with the rhoptry-associated proteins 1 and 2 (RAP-1 and RAP-2), here we assessed the genetic variability of the Plasmodium vivax rap-1 and rap-2 genes isolated from Colombian parasite populations.

|
RAP-1 and RAP-2 HABPs inhibited binding of RAP-3 HABPs to different extents, thus suggesting the recognition of similar binding sites on RBC membrane, as well as ability of RAP-3 HABPs to inhibit P. falciparum infection in vitro.
|
79 |
20833215
|
Altogether, these functional analyses of RAP-3 HABPs strongly suggest a potential role for this protein in RBC invasion, and highlight its HABPs as potential targets to develop a fully protective minimal subunit-based malarial vaccine.
