Special Issue of International Journal of Molecular Sciences “Opioid Receptors and Endorphinergic Systems 2.0”

Abstract

Opioid peptides exhibit a wide-ranging tissue distribution and control multiple tissue functions not only through reflex mechanisms involving the central nervous system or the modulation of neurotransmitter release, but also by acting directly at the cellular level by targeting selected receptor subtypes (μ, δ, and κ are among the most frequently expressed) [...]
