In another study, three to twenty copies of NPNA repeat sequences from CSP were presented in the tobacco mosaic virus (TMV) platform, and this vaccine candidate induced a 10-fold higher antibody titer than that elicited by a nearly full-length CSP in mice [26], implying that a vaccine based on an optimized epitope focusing on the repeat region of CSP may be a good strategy to develop a malaria vaccine. The gene discussed is DNAJC5; the disease is malaria.
