Researchers tested the ability of the entire H2B protein of L. major, its divergent or conserved regions to provide protection against virulent L. major challenge. The divergent amino-terminal region of H2B is able to confer potent protection against a virulent challenge in BALB/c mice (Chenik et al., 2006).
