From: Protein-bound sialic acid in saliva contributes directly to salivary anti-influenza virus activity
Age-related differences in salivary anti-IAV activity. Comparison of (A) the saliva secretion rate (mL/min), (B) salivary anti-IAV activity against the PR8 IAV strain, (C) BSA concentration in saliva, and (D) correlation between salivary anti-IAV activity against the PR8 IAV strain and the concentration of BSA in young people (30 boys and 30 girls aged 5–19 years), middle adults (60 men and 60 women aged 20–59 years), and elderly people (30 men and 30 women aged 60–79 years). Data are presented as mean ± SD of each group. Average plateau values were compared using one-way analysis of variance and the Kruskal–Wallis test. *p < 0.05; ***p < 0.001.
