From: Up-regulation of Toll-like receptors 2, 3 and 4 in allergic rhinitis
Quantitative immunoreactivity of TLR2, TLR3 and TLR4 in nasal mucosa. Quantitative analysis of TLR2 (A), TLR3 (B) and TLR4 (C) immunostaining in nasal epithelium in biopsies from healthy volunteers (controls), from patients with intermittent allergic rhinitis before nasal allergen challenge and from the same patients after allergen challenge. TLR immunoreactivity is expressed in relation to the area of mucosal tissue. Lines connecting patients before and after allergen challenge represent paired data. Increase in the immunostaining for TLR2 (*p < 0.05), TLR3 (*p = 0.05) and TLR4 (*p < 0.05) after allergen challenge.
