A Novel Strategy to Produce 6-cys Proteins Based on Pfs230D1 Domain Fusions

Description:

The Plasmodium parasite has a complex lifecycle during human infection and in the mosquito vector. Most advanced malaria vaccine candidates can confer only partial, short-term protection in malaria-endemic areas. A means of breaking the transmission of malaria to subsequent individuals could prevent a significant amount of human disease.

The primary embodiments of this technology are novel compositions of matter that produce enhanced transmission-blocking responses over current transmission blocking vaccines:

  • The inventors designed fusion protein sequences incorporating Pfs230 domain1 (Pfs230D1) at the N-terminus with additional Plasmodium 6-cys domains downstream.
  • The artificial immunogens retained structured transmission blocking epitopes.

This technology is available for licensing for commercial development in accordance with 35 U.S.C. § 209 and 37 CFR Part 404, as well as for further development and evaluation under a research collaboration.
