Research Overview
PACAP-27
PACAP-27 has been repeatedly shown to support beta-cell survival through cAMP/PKA and related pathways. In experimental models it mitigates cytokine damage, preserves insulin content, and helps maintain islet viability.
Insulin Lispro
Clinical studies show faster onset and shorter duration than regular insulin, improving post-meal glucose control. It is a standard comparator in diabetes pharmacology and closed-loop insulin-delivery research.
