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%.

Effect of montelukast on platelet activating factor- and tachykinin induced mucus secretion in the rat [PDF]

open access: yes, 2008
Background: Platelet activating factor and tachykinins (substance P, neurokinin A, neurokinin B) are important mediators contributing to increased airway secretion in the context of different types of respiratory diseases including acute and chronic ...

Neurokinin B and the hypothalamic regulation of reproduction [PDF]

open access: yesBrain Research, 2010
Loss-of-function mutations in the genes encoding either neurokinin B (NKB) or its receptor, NK3 (NK3R), result in hypogonadotropic hypogonadism, characterized by an absence of pubertal development and low circulating levels of LH and gonadal steroids. These studies implicate NKB and NK3R as essential elements of the human reproductive axis.

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 ...

Decreased neurokinin B as a risk factor of functional hypothalamic amenorrhea

open access: yesGynecological Endocrinology, 2023
Background Neurokinin B (NKB) belongs to the tachykinin family of proteins who’s regulation is essential for proper function of the reproductive system.

Neurokinin receptors in the gastrointestinal muscle wall: cell distribution and possible roles

open access: yesBiomolecular Concepts, 2013
The neurokinin receptors are G-protein-linked receptors; three distinct molecules, called neurokinin-1, neurokinin-2, and neurokinin-3 receptors, have been identified.

A Neural Circuit Underlying the Generation of Hot Flushes

open access: yesCell Reports, 2018
Summary: Hot flushes are a sudden feeling of warmth commonly associated with the decline of gonadal hormones at menopause. Neurons in the arcuate nucleus of the hypothalamus that express kisspeptin and neurokinin B (Kiss1ARH neurons) are candidates for ...

Substance P, neurokinin A and neurokinin B in the ocular response to injury in the rabbit [PDF]

open access: yesBritish Journal of Pharmacology, 1988
Substance P (SP) and neurokinin A‐ (NKA)/neurokinin B (NKB)‐like immunoreactivity (LI) were measured by radioimmunoassay in extracts of the rabbit uvea. The iris‐ciliary body complex contained 3–4 times more NKA/NKB‐LI than SP‐LI. Tachykinins are thought to mediate many of the responses to ocular injury in the rabbit.

Autocrine regulation of human sperm motility by tachykinins

open access: yesReproductive Biology and Endocrinology, 2010
Background We examined the presence and function of tachykinins and the tachykinin-degrading enzymes neprilysin (NEP) and neprilysin-2 (NEP2) in human spermatozoa.

Role of neurokinin B in ovine puberty

open access: yesDomestic Animal Endocrinology, 2020
Puberty is the process whereby an individual acquires the ability to reproduce, and the attainment of puberty in a timely manner is critical for both humans and livestock. For livestock, the initiation of puberty at the appropriate time aids in increasing lifetime productivity, thus maximizing profitability for producers.
