OBJECTIVE Recent guidelines reveal that allergic rhinitis impairs quality of life. Neuropeptides play a central role in allergy-related nasal inflammation. The objective of this study was to analyze the release of neuropeptides (substance P, neurokinin A, and vasoactive intestinal peptide) in nasal lavage and their modification by intranasal fluticasone propionate as an established therapy in p...
Kisspeptin, which is the product of the kiss1 gene and its receptor kiss1r, have emerged as the essential gatekeepers of reproduction. The present study used gonadally intact female rats to evaluate fasting-induced suppression of the KiSS-1 system of anteroventral periventricular nucleus (AVPV) and arcuate nucleus (ARC) under normal physiological conditions. Starting on the day of estrous, one...
BACKGROUND Tachykinins substance P, neurokinin A and neurokinin B seem to account for asthma pathophysiology by mediating neurogenic inflammation and several aspects of lung mechanics. These neuropeptides act mainly by their receptors NK1, NK2 and NK3, respectively which may be targets for new asthma therapy. METHODS This review systematically examines randomized controlled trials evaluating ...
C-reactive protein (CRP), an innate immune mediator, is elevated in the circulation before symptoms in patients with preeclampsia, a severe hypertensive pregnancy disorder with high mortality and morbidity. However, the specific sources underlying increased CRP and the role of elevated CRP in preeclampsia are undefined. Here, we report that circulating CRP levels are significantly increased in ...
Immunoreactivities of mammalian tachykinins have been widely demonstrated in the peripheral and central nervous systems (Ogawa et al. 1985; Leeman et al. 1991; Otsuka and Yoshioka, 1993). Dalsgaard et al. (1985) reported the co-existence of substance P(SP) and neurokinin A (NKA)-like immunoreactivities in neurons of rat dorsal root ganglia (DRG) and the dorsal horn of the spinal cord. Recently,...

Inflammation, trauma, or nerve injury may cause enduring hyperalgesia, an enhanced sensitivity to painful stimuli. Neurons in lamina I of the spinal dorsal horn that express the neurokinin 1 receptor for substance P mediate this abnormal pain sensitivity by an unknown cellular mechanism. We report that in these, but not in other nociceptive lamina I cells, neurokinin 1 receptor-activated signal...
We report a novel peptide probe for the detection of neurokinin-1 receptor using disaggregation-caused signal enhancement. The probe was obtained via the aggregation of a modified substance P in a terpyridine-Fe (II) complex with Gd (III)-DOTA into well-defined nanostructures, which effectively weaken ligand fluorescence and slow the exchange rate of inner-sphere water molecules. This probe dis...
