In BPH, several salivary elicitors and effectors, such as NlMLP (N. lugens-secreted mucin-like protein) [62], NlEG1 (N. lugens salivary endo-β-1,4-glucanase) [63] and NlSEF1 (N. lugens salivary EF-hand calcium-binding protein) [47], have been reported. Here, MUC2 is linked to benign prostatic hyperplasia.
