Peptides are short chains of 2 to 50 amino acids linked by covalent peptide bonds. Structurally smaller than proteins, they serve as highly specific biological signaling molecules. functioning as hormones, growth factors, neurotransmitters, and immune modulators in biological systems.

Biological systems produce endogenous peptides. Research peptides mimic or modulate these natural signals to investigate specific cellular responses in experimental contexts.

How Peptides Work at the Cellular Level

Receptor Binding
Peptides bind to specific receptors on cell surfaces, activating targeted downstream signaling cascades
Tissue Repair
Influence cell migration patterns, modulate angiogenic signaling, and support regenerative processes in muscle, tendon, and connective tissue models
Immune Modulation
Modulate immune cell signaling, investigate inflammatory response pathways, and examine adaptive immune mechanisms
Hormone Regulation
Modulate endocrine pathway responses, including growth hormone signaling, metabolic rate mechanisms, and appetite-related pathways
Metabolic Function
Influence mitochondrial energy production, fat oxidation, and cellular metabolic efficiency
Collagen Synthesis
Activate fibroblast signaling and stimulate collagen and elastin production in tissue models

Why Peptides Over Traditional Therapeutics

High Specificity Target specific cell receptors with high precision, reducing unintended interactions
Natural Metabolism Broken down into amino acids the body already uses. No toxic metabolites
Clinical Momentum 80+ FDA-approved peptide drugs, 150+ in clinical trials, 600+ in preclinical development (PMC)
