name:
An immunologically cryptic epitope of Plasmodium falciparum circumsporozoite protein facilitates liver cell recognition and induces protective antibodies that block liver cell invasion.
description:
In further experiments designed to investigate whether polymorphisms can attribute to a change in recognition of the peptide, two variant peptides were synthesized where Lys12 of the peptide was substituted by an asparagine and threonine. Both of the variants showed a 40% decrease inrecognition in comparison with the native sequence, suggesting that these changes in the field isolates are mostlikely associated with immune evasion. Also, deletions of as few as 3 amino acids from either end led to a 50% decrease in the recognition of the epitope by the antibodies.
