Figure 4 : (a) A photomicrograph of a section in the nasal mucosa of the control group showing mildly
expressed TLR-9 reaction in cytoplasm of apical epithelial surface (black arrow). (b) A photomicrograph of
a section in the nasal polyp of group IIb showing highly expressed TLR-9 reaction in epithelium and lamina
propria (black arrow). (c) A photomicrograph of a section in the nasal polyp of group IIa showing moderately
expressed TLR-9 reaction in epithelium and lamina propria (black arrow). (d) A photomicrograph of a section
in the nasal polyp of group IIIb showing highly expressed TLR-9 reaction in epithelium and lamina propria
(black arrow). (e) Aphotomicrograph of a section in the nasal polyp of group IIIa showing mildly expressed
TLR-9 reaction in epithelium and lamina propria (black arrow). [TLR-9 immunostaining, X 400].
