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 Aspart
Research consistently shows faster onset and earlier peak action than regular human insulin. It is commonly studied for meal-time glycemic control and pump-based insulin delivery.
