In clean muscle contractility assays, many NK1 receptor (NK1r) antagonists inhibit responses towards the neurotransmitter, substance P (SP), and its own analogue, septide, with markedly different potency, resulting in the proposal that there surely is a septide-preferring receptor linked to the NK1r. with which it competes. Therefore it may not really be essential to posit… Continue reading In clean muscle contractility assays, many NK1 receptor (NK1r) antagonists inhibit
