Eledoisin-related peptides are primarily utilized in research settings to study the role of tachykinin receptors in various physiological processes. These peptides are often employed in neuroscience to investigate their effects on neurotransmission and pain signaling pathways. They are also used in pharmacological studies to explore potential therapeutic applications, particularly in conditions involving inflammation or smooth muscle contraction. Additionally, eledoisin-related peptides serve as valuable tools in understanding the mechanisms of peptide-receptor interactions, aiding in the development of targeted drugs for neurological and inflammatory disorders.
