The olfactory epithelium (OE) undergoes changes during aging and this may affect inflammatory responses and immune cell infiltration. Here the authors look at the effect of aging on OE and how this involves cross talk between T cells and horizontal basal cells involving Il17a expression in OE which is increased in aging and inhibition of IL-17a function reduces respiratory metaplasia.
