Anti-plasmodium composition and methods of use
Compositions that inhibit the binding of Plasmodium falciparum to erythrocytes are provided. More particularly, antibodies specific for Plasmodium falciparum binding proteins and blocking peptides that prevent the binding of Plasmodium falciparum are included in the present invention. The methods provided utilize the antibody and peptide compositions provided herein and include methods for the diagnosis, prevention, and treatment of Plasmodium falciparum diseases such as malaria as well as methods for the detection of Plasmodium falciparum in biological samples and culture media.
1. An isolated antibody, wherein the antibody specifically binds a region of a RII/F2 region of an EBA-175 protein from a Plasmodium species, wherein the region consists of a 10 amino acid sequence and wherein the amino acid sequence is shown in SEQ ID NO: 1.
2. The isolated antibody of claim 1 , wherein the P. species is Plasmodium falciparum.
3. The isolated antibody of claim 1 , wherein the antibody inhibits binding of an EBA-175 protein to a red blood cell.
4. The isolated antibody of claim 1 , wherein the antibody inhibits Plasmodium falciparum invasion into a red blood cell.
5. The isolated antibody of claim 4 , wherein the antibody inhibits Plasmodium falciparum invasion of a red blood cell in vitro.
6. The isolated antibody of claim 4 , wherein the antibody inhibits Plasmodium falciparum invasion of a red blood cell in vivo.
7. The isolated antibody of claim 1 , wherein the antibody is monoclonal.
8. A hybridoma producing the monoclonal antibody of claim 7 .
