まとめ

迷走神経は通常,腫瘍死滅因子 (TNF) の放出を阻害することによって炎症を制御します. 研究者らは,アルファ7ニコチンアセチルコリン受容体が,この"ホルモンによる抗炎症経路"に不可欠であることを発見した.

科学分野:

免疫学免疫学とは
神経科学は神経科学である.
薬理学薬理学とは

背景:

過剰な炎症とTNF合成は,セプシスやリウマチ性関節炎のような重症疾患に寄与する.
神経系は,迷走神経を介して,炎症反応を抑制することができます.
この"コリン性抗炎症経路"を媒介する特定の受容体は特定されなかった.

研究の目的:

マクロファージのTNF放出の迷走神経媒介阻害に起因する主要な受容体を特定する.
コリン性抗炎症経路の分子メカニズムを解明する.

主な方法:

TNF合成の調節におけるアルファ7ニコチンアセチルコリン受容体の役割を調査した.
野生型のマウスとアルファ7欠乏マウスを利用した.
ヴァガス神経に電気刺激を施した.

主要な成果:

ヴァガス神経刺激は,野生型のマウスのTNF合成を成功裏に抑制しました.
この抑制は,アルファ7ニコチンアセチルコリン受容体を持たないマウスでは存在しない.
アルファ7サブユニットは,マクロファージのTNF放出に対するアセチルコリンの作用に不可欠です.

結論:

ニコチンアセチルコリン受容体α7サブユニットは,コレニン効果抗炎症経路の重要な受容体です.
この発見は,炎症性疾患を理解し,治療するための重要な意味を持つ.

The Mechanics of (Poro-)Elastic Contractile Actomyosin Networks As a Model System of the Cell Cytoskeleton

In this work, an in vitro reconstitution approach is employed to study the poroelasticity of actomyosin gels under controlled conditions. The dynamics of the actomyosin gel and the embedded solvent are quantified, through which the network poroelasticity is demonstrated. We also discuss the experimental challenges, common pitfalls, and relevance to cell cytoskeleton...

Macro-Rheology Characterization of Gill Raker Mucus in the Silver Carp, Hypophthalmichthys molitrix

This protocol presents a method to perform rheology characterization of mucus that resides on gill rakers (GRs) of the silver carp. Viscoelastic characteristics of GR-mucus, obtained by measuring viscosity, storage and loss moduli, are evaluated for the apparent yield stress to understand the filter feeding mechanism in...
