Evidence has been provided of enhanced epithelial transforming growth factor-beta (TGF-beta) immunoreactivity in allergic rhinitis, including correlation with intra-epithelial mast cell numbers, and the co-localisation of TGF-beta receptors to mast cells, suggesting that the epithelial expression of TGF-beta may represent an important biological process involved in either the recruitment or retention of mast cells within the epithelium in naturally occurring allergic rhinitis.
