Overall, the outcomes of the study revealed not only how the body can establish its own force field against infection but also how bacteria can use their own weaponry to evade and destroy the protective layer. In the context of human health, the authors suggest this may lay the ground for future research for drug and vaccine delivery. By working with the shield, absorption can be improved and the effect enhanced. In addition, there may be the potential to develop better acting probiotic species; one such bacterium, _Lactobacillus _already possesses the ability to interact with the epithelium to benefit rather than cause harm. Whether the route is natural or medical, increasing the harmonization with our human shields can only mean a better future for us all.
