In our previous studies, it has been found that recombinant phage displaying peptide KPVQHALLTPLGLDR (KR, one of the four peptides) could enhance the immune responses of T helper (Th) 1 and Th17 cells and elicit antibody against Gp70 in BALB/c mice, leading to the inhibition of subsequent infection of the mice (Chen et al., 2017). Here, EMB is linked to infection.
