Researchers Develop Novel Delivery System for Hydrophilic Peptides
A team at MIT has developed a lipid nanoparticle formulation capable of delivering hydrophilic peptides orally with bioavailability exceeding 30%, compared to typical subcutaneous injection efficiency. The platform was demonstrated with BPC-157 analogs in a rodent pharmacokinetic study.
Copper Peptide Concentration Found Critical for Collagen Synthesis Outcomes
New in-vitro research suggests that the concentration window for optimal GHK-Cu activity is narrower than previously thought, with both sub- and supra-therapeutic concentrations producing suboptimal collagen mRNA expression in dermal fibroblast cultures.
Melanocortin System Peptides Show Dual Role in Appetite and Inflammation
Studies using PT-141 analogs have revealed an unexpected anti-inflammatory mechanism mediated through MC4R activation in macrophages, separate from the known central nervous system appetite-suppression pathway, opening new avenues in metabolic and inflammatory disease research.
