Interleukin-6 (IL-6) is a pro/anti-inflammatory cytokine, the quantitative detection of which has been extensively considered for diagnosis of inflammatory associated diseases. However, there has not yet been a reliable, low-cost, and user-friendly platform developed for point-of-care (POC) detection of IL-6, which will eliminate the conventional costly, time-consuming, and complex assays. In this work, we developed a lateral flow assay for colorimetric detection of IL-6, using anti-IL-6 antibodies conjugated to gold nanoparticles (AuNPs) as the detection probes. Silver amplification technique was incorporated with the newly developed assay in order to enhance the obtained colorimetric signals, allowing sensitive detection of IL-6 in human serum in the desired physiological ranges (i.e., 5-1000 pg/mL). A limit of detection of 5 pg/mL could be achieved for IL-6 detection in serum with the amplification step which was not achievable in the standard assay. The corresponding specificity and reproducibility tests were all preformed to confirm the reliability of this assay for quantitative measurement of IL-6 in a POC manner.

Neurotensin via Type I Receptor Modulates the Endotoxemia Induced Oxido-Inflammatory Stress on the Sympathetic Adrenomedullary System of Mice Regulating NF-κβ/Nor-Epinephrine Pathway.

The present study investigated the role of the neurotensin/NTS in the modulation of the lipopolysaccharide/LPS induced dysfunction of the sympatho-adrenal-medullary system/SAM using both the NTS receptor 1/NTSR agonist PD149163/PD and antagonist SR48692 /SR. Forty eight mice were maintained in eight groups; Group I/control, Groups II, III, IV, and VII received LPS for 5 days further Group III/IV/VII received PD low dose/PD, PD high dose /PD and SR for 28 days respectively. Group V/VI received similar only PD and PD dose respectively whereas Group VIII was exposed to only SR for 28 days.

The inflammatory response of lung tissue and abnormal proliferation of pulmonary artery smooth muscle cells are involved in the pathogenesis of high-altitude pulmonary hypertension (HAPH). Halofuginone (HF), an active ingredient derivative of Chang Shan (Dichroa febrifuga Lour. [Hydrangeaceae]), has antiproliferative, antihypertrophic, antifibrotic, and other effects, but its protective effects on HAPH remains unclear.

Rapid and sensitive protein detection methods are of benefit to clinical diagnosis, pathological mechanism research, and infection prevention. However, routine protein detection technologies, such as enzyme-linked immunosorbent assay and Western blot, suffer from low sensitivity, poor quantification and labourious operation. Herein, we developed a fully automated protein analysis system to conduct fast protein quantification at the single molecular level.

Interleukin-11 (IL-11) is a member of the IL-6 family of cytokines and possesses both pro- and anti-inflammatory properties. IL-11 activates its target cells via binding to a membrane-bound IL-11R and subsequent formation of a homodimer of the signal-transducing receptor gp130. Thus, the expression pattern of the IL-11R determines which cells can be activated by IL-11.
