“…SLURP1 is expressed abundantly in the cornea and moderately in oral mucosa, skin and other epithelia, where it is secreted into tear, saliva, sweat, and urine (Adermann et al, 1999; Norman et al, 2004). It is also expressed in bronchial epithelial cells, a variety of immune cells, primary sensory neurons, and the retina (Fujii et al, 2014; Horiguchi et al, 2009; Mastrangeli et al, 2003; Matsumoto et al, 2012; Moriwaki et al, 2007, 2009). SLURP1 is a ligand of α7-nAchR and a late marker of epidermal differentiation (Chimienti et al, 2003; Favre et al, 2007; Horiguchi et al, 2009).…”
