Cholesterol efflux

Arteriosclerosis thrombosis and vascular biology, 2012
Monocytosis and neutrophilia are well-established risk factors for atherosclerosis and seem to play a causative role in lesion development. Studies in mice with defects in cholesterol efflux pathways have identified novel roles for the ATP-binding cassette transporter A1, ATP-binding cassette transporter G1, and apolipoprotein E in suppressing ...

Bimetallic Nanoreactor Activates cGAS‐STING Pathway via mtDNA Release for Cancer Metalloimmunotherapy

Advanced Functional Materials, EarlyView.
A bimetallic Mn–Ca nanoreactor (MCC) is developed as a non‐nucleotide STING nanoagonist for cancer metalloimmunotherapy. MCC induces Ca2+ overload and hydroxyl radical generation, resulting in mitochondrial damage and mtDNA release. The released mtDNA cooperates with Mn2+ to robustly activate cGAS–STING signaling.

Bacterial Drug Efflux Proteins.

Nippon Saikingaku Zasshi, 1995
近年,数多くの薬剤排出系が様々な菌種に見いだされ,有力な化学療法剤耐性機構として認識されつつある。特に,臨床上問題視されているMRSAや緑膿菌などの多剤耐性菌に薬剤排出蛋白が多く存在することは注目すべきである。遺伝子解析により多くの排出蛋白のアミノ酸配列が明らかにされた。薬剤排出蛋白はいずれも細胞質膜に存在するが,薬剤排出のエネルギー源として,H+の電気化学的勾配を用いるものと,ATPを用いるものと2種類ある。また,構造上関連性のない多種の薬剤を認識し排出する多剤排出蛋白の存在が排出による薬剤耐性のひとつの特徴であるが,特異性の高い排出蛋白との間で一次配列の相同性が高く,多剤排出蛋白がどのように基質を認識しているのか興味が持たれる ...

Raman Microscopy at the Organic–Inorganic Interfaces in Human Calcified Aortic Valves Shows the Co‐Existence of Whitlockite Crystals and Carbonated Hydroxyapatite‐Mineralized Collagen Fibrils

Advanced Functional Materials, EarlyView.
This study advances our understanding of aortic valve stenosis by capturing spatially resolved chemical and structural changes at the nanoscale. The findings highlight the potential of combined Raman and electron microscopy for understanding calcification mechanisms across diverse tissue types.

Effects of Monovalent and Divalent Cations on Ca2+ Fluxes Across Chromaffin Secretory Membrane Vesicles [PDF]

, 1983
: Bovine chromaffin secretory vesicle ghosts loaded with Na+ were found to take up Ca2+ when incubated in K+ media or in sucrose media containing micromolar concentrations of free Ca2+. Li+- or choline+loaded ghosts did not take up Ca2+.

Solar Heating Enhanced Selective Recovery of Metal Ions Through Flowing Electrodes Enabled by Hybrid Carbon Nanostructures

Advanced Functional Materials, EarlyView.
A new electrochemical system based on a microporous hybrid of carbon nanoplatelets and nanotubes to selectively capture Ni2+ from wastewater is constructed. The system temperature rises rapidly when irradiated with sunlight, which enhances the Ni2+ removal rate by 250% and the selectivity by 53%, and the energy consumption is also reduced by 51 ...

Multidrug Efflux Systems in Helicobacter cinaedi

Antibiotics, 2012
Helicobacter cinaedi causes infections, such as bacteremia, diarrhea and cellulitis in mainly immunocompromised patients. This pathogen is often problematic to analyze, and insufficient information is available, because it grows slowly and poorly in ...
