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 Glargine
Clinical and translational studies support its use as a basal comparator because of prolonged absorption and stable glycemic control. It is heavily used in basal-bolus regimen research and insulin-delivery optimization studies.
