Research Overview
Histatin-5
Histatin-5 is a major salivary defense peptide that can kill Candida species and influence oral microbial communities. It is also investigated for wound-healing and xerostomia-associated oral infection models.
Linaclotide
Linaclotide has extensive clinical evidence for chronic idiopathic constipation and IBS-C, with consistent effects on stool frequency and abdominal symptom relief. Its mechanism is local GC-C activation in the gut with minimal systemic exposure.
