1. We identified a unique pathogenic mechanism
on how Helicobacter pylori can survive by hiding
inside the autophagosomes in cells.
2. We discovered a novel antibacterial signalling pathway of VD3 through the activation of PDIA3/STAT3 - MCOLN3 - Ca2+ axis, to reactivate the lysosomal acidification and degradation function of autolysosomes, which is the key signal pathway for the antibacterial action of VD3 both in cells and in animals and perhaps further in humans.
