The incidence of β-defensin-1, 2, 3 in human healthy and chronically inflamed nasal and tonsillar mucosa

It was assumed that the incidence of HBD-1, 2, 3 was lower in tonsils than in nasal mucosa; however, inflamed samples of tonsils and nasal mucosa showed no difference in the production of HBD-1, 2, 3. The presence of all three subfamilies of HBD was significantly lower in nasal polyps with S. aureus positive than in the negative control.
