New month, new paper! Very happy to have this review published in Life

I put together an overview of what we know about how microbes affect the physiology of cell-cell junctions in the gut (we know a bit), the blood-brain barrier (we know a little bit) and the epidermis (we know very little at all...). Hopefully it'll be useful/interesting, but the main conclusion is that there is still so much more to learn!
