We have successfully developed dendritic cell vaccines loaded with LM peptides and deciphered that two peptides from this pathogen’s virulence factors, listeriolysin O (LLO) and glyceraldehyde-3-phosphate-dehydrogenase (GAPDH), LLO91–99 and GAPDH1–22, conferred significant listeriosis protection in two mice models sensitive and resistant to listeriosis [8,9,10]. Here, GAPDH is linked to listeriosis.
