- Chemical Identity
- 28-amino-acid neuropeptide from secretin superfamily
- Identical. Same 28-amino-acid sequence
- No structural difference. Same molecule
- Amino Acid Sequence
- HSDAVFTDNYTRLRKQMAVKKYLNSILN
- Identical sequence. Abbreviation doesn't change structure
- The name is cosmetic. The peptide is the same
- Receptor Targets
- VPAC1, VPAC2
- Both names refer to the same receptor-binding molecule
- Tissue Distribution
- CNS, PNS, gut, immune cells, vasculature
- Identical distribution. Found in same tissues
- Location independent of naming convention
- Primary Functions
- Vasodilation, immune modulation, circadian regulation
- Same functions. Neuroprotection, anti-inflammatory, GI motility
- Functional profile unchanged by nomenclature
- Research Applications
- Neuroinflammation, autoimmune models, circadian studies
- Identical applications. Same experimental uses
- Literature uses 'VIP' almost exclusively
