Implication

Laboratory study reveals synthetic circumsporozoite protein peptides stimulate T lymphocytes in exposed and nonimmune donors, indicating viable targets for malaria vaccine development.

Key Points

Identify T-cell recognition sites within nonrepetitive regions of the Plasmodium falciparum circumsporozoite protein for potential inclusion in a malaria vaccine.
Synthesized peptides corresponding to three predicted T-cell recognition sites within the Plasmodium falciparum circumsporozoite protein.
Assayed proliferation of peripheral blood lymphocytes from donors in a malaria-endemic area and nonimmune donors (N=22).
Generated peptide-specific human T-cell clones to test recognition against native protein purified from sporozoites.
Peripheral blood lymphocytes from 15 of 22 donors (68.2%), including 4 of 6 nonimmune individuals (66.7%), proliferated in response to one or more peptides.
Derived T-cell clones specific for one peptide demonstrated successful recognition of native circumsporozoite protein purified from sporozoites.
