Research Overview
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.
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.
