NMR methods provide information about conformational dynamics of GPCRs over a wide range frequencies in aqueous media at near-physiological temperature, with minimal modification the wild-type GPCR covalent structures. Here we review our solution studies functionrelated GPCRs, including β2 adrenergic receptor, μ opioid and adenosine A2A receptor.

We have previously demonstrated that stimulation of the angiotensin (Ang) II type 2 receptor in vascular smooth muscle cells caused bradykinin production by activating kininogenase in transgenic mice. The aim of this study was to determine whether overexpression of AT2 receptors in cardiomyocytes attenuates Ang II-induced cardiomyocyte hypertrophy or interstitial fibrosis through a kinin/nitric...

The 6-lymphocyte-restricted adhesion protein CD22 mediates sialic acid-dependent cell-cell interactions. Engagement of CD22 on B lymphocytes with a CD22 monoclonal antibody (MoAb) H622.7 that blocks the binding of CD22 to its ligand(s) directly stimulated 6-cell proliferation. In addition, the HB22.7 MoAb costimulated 6-cell proliferation with either anti-lgM, interleukin-2 (IL-2). IL-4, or CD4...

BackgroundChronic rhinosinusitis (CRS) can be divided into endotypes by functional or pathophysiologic findings.ObjectiveThe aim of this study was to analyze the expression cytokines, prostaglandin (PG) synthases, and their receptors related pathogenesis CRS, especially those contributing nasal polyp (NP) formation.MethodsNPs uncinate tissue (UT) samples were collected from 90 patients who unde...

Interleukin (IL)-22 is a member of the IL-10 family. Its main targets are epithelial cells, not immune cells. We examined IL-22 signal transduction in oral squamous cell carcinoma (OSCC) cells. Immunohistochemical staining revealed that IL-22R was expressed more highly in OSCC compared to normal regions. An IL-22R signal was also observed in metas...

Human squamous cell carcinoma cell lines often possess increased levels of epidermal growth factor (EGF) receptor. The growth of these EGF receptor-hyperproducing cells is usually inhibited by EGF. To investigate the mechanism of EGF-mediated inhibition of cell growth, variants displaying alternate responses to EGF were isolated from two squamous cell carcinoma lines, NA and Ca9-22; these cell ...

in this paper, a general introduction is given, presenting the overactive bladder syndrome (oab) and its impact on the quality of life and economical burden in patients affected. moreover, the anatomy, physiology and histology of the lower urinary tract are discussed, followed by a brief overview on the possible role of prostaglandin (pg) and phosphodiesterase type 5 (pde5) in the urinary bladd...
