Structure-activity relationship study of tachykinin peptides for the development of novel neurokinin-3 receptor selective agonists. [PDF]

open access: yes, 2013
Neurokinin B (NKB) is a potential regulator of pulsatile gonadotropin-releasing hormone (GnRH) secretion via activation of the neurokinin-3 receptor (NK3R).

Tachykinin neuropeptides in cerebellar granule neurons: an immunocytochemical study

open access: yesEuropean Journal of Histochemistry, 2009
We previously demonstrated that exogenously administered neurokinin A and neurokinin B, but not substance P, increased the sensitivity of cultured cerebellar granule neurons (CGNs) to glutamate.

Substance P selectively decreases paired pulse depression in the rat hippocampal slice

open access: yesBMC Neuroscience, 2005
Background Although being widespread in the hippocampus, the role tachykinins play in synaptic transmission is unclear. The effect of substance P on field potentials evoked by stimulation of the Schaffer collateral-commissural fibres and recorded from ...

Neuropeptide modulation of lymphatic smooth muscle tone in the canine forelimb

open access: yesMediators of Inflammation, 1992
Neurokinin A and B are putative inflammatory mediators. We assessed their ability to alter prenodal lymphatic resistance. Intralymphatic neurokinin A (3.0 × 10−6, 3.0 × 10−5 and 3.0 × 10−4 mol l−1) significantly constricted lymphatics at the two highest ...

Possible causes and treatment strategies for the estrus and ovulation disorders in dairy cows

open access: yesThe Journal of Reproduction and Development, 2022
The reproductive performance of dairy cows has declined, along with an increase in their milk yield. First-service conception rates in lactating dairy cows are often lower than 50%.

Radiochemical Synthesis and Evaluation of Novel Radioconjugates of Neurokinin 1 Receptor Antagonist Aprepitant Dedicated for NK1R-Positive Tumors

open access: yesMolecules, 2020
Aprepitant, a lipophilic and small molecular representative of neurokinin 1 receptor antagonists, is known for its anti-proliferative activity on numerous cancer cell lines that are sensitive to Substance P mitogen action.

Role of KNDy Neurons Expressing Kisspeptin, Neurokinin B, and Dynorphin A as a GnRH Pulse Generator Controlling Mammalian Reproduction

open access: yesFrontiers in Endocrinology, 2021
Increasing evidence accumulated during the past two decades has demonstrated that the then-novel kisspeptin, which was discovered in 2001, the known neuropeptides neurokinin B and dynorphin A, which were discovered in 1983 and 1979, respectively, and ...

The effect of the tachykinin NK2 receptor antagonist MEN11420 (nepadutant) on neurokinin A-induced bronchoconstriction in asthmatics

open access: yesTherapeutic Advances in Respiratory Disease, 2009
Objective: We previously reported that the nonpeptide tachykinin NK 2 receptor antagonist SR48968 (saredutant) significantly inhibits neurokinin A-induced bronchoconstriction in patients with asthma. MEN11420 (nepadutant) is a bicyclic peptide tachykinin

Multidrug Resistance Protein Transporter and Ins(1,4,5)P3-Sensitive Ca2+-Signaling Involved in Adenosine Triphosphate Export via Gq Protein–Coupled NK2-Receptor Stimulation With Neurokinin A

open access: yesJournal of Pharmacological Sciences, 2010
The purpose of this study is to identify the membrane transport machinery and cell signaling involved in the neurokinin A–inducible release of adenosine triphosphate (ATP) as an autocrine/paracrine signal from cultured guinea-pig taenia coli (T.

NEUROGENIC MODULATION BY NEUROKININ-1 RECEPTOR ANTAGONIST, CP-96,345 TO INHIBIT RHEUMATOID ARTHRITIS DEVELOPMENT IN ADJUVANT INDUCED ARTHRITIS RAT MODEL

open access: yesFolia Medica Indonesiana, 2017
Rheumatoid arthritis (RA) is a chronic form of persistent inflammation. Meanwhile, Substance P is the most associated neuropeptide in neurogenic inflammation and hyperalgesia commonly found in chronic pain.
