Human Multidrug Resistance ABCB and ABCG Transporters: Participation in a Chemoimmunity Defense System

Reads0
Chats0
TLDR
It is suggested that multidrug transporters are essential parts of an innate defense system, the "chemoimmunity" network, which has a number of features reminiscent of classical immunology.
Abstract
In this review we give an overview of the physiological functions of a group of ATP binding cassette (ABC) transporter proteins, which were discovered, and still referred to, as multidrug resistanc...

Lipids and lipid-based formulations: optimizing the oral delivery of lipophilic drugs

TL;DR: The mechanisms by which lipids and lipidic excipients affect the oral absorption of lipophilic drugs are detailed and a perspective on the possible future applications of lipid-based delivery systems is provided.

Guidelines for the use of flow cytometry and cell sorting in immunological studies (second edition)

Andrea Cossarizza, +462 more
TL;DR: These guidelines are a consensus work of a considerable number of members of the immunology and flow cytometry community providing the theory and key practical aspects offlow cytometry enabling immunologists to avoid the common errors that often undermine immunological data.

Human kidney proximal tubule-on-a-chip for drug transport and nephrotoxicity assessment.

TL;DR: A microfluidic device lined by living human kidney epithelial cells exposed to fluidic flow that mimics key functions of the human kidney proximal tubule is described, suggesting that it might serve as a useful tool for evaluating human-relevant renal toxicity in preclinical safety studies.

A four-organ-chip for interconnected long-term co-culture of human intestine, liver, skin and kidney equivalents

TL;DR: This study is the first approach to establish a system for in vitro microfluidic ADME profiling and repeated dose systemic toxicity testing of drug candidates over 28 days in co-culture, and assures near to physiological fluid-to-tissue ratios.

Distantly related sequences in the alpha- and beta-subunits of ATP synthase, myosin, kinases and other ATP-requiring enzymes and a common nucleotide binding fold.

TL;DR: Related sequences in both alpha and beta and in other enzymes that bind ATP or ADP in catalysis help to identify regions contributing to an adenine nucleotide binding fold in both ATP synthase subunits.

A surface glycoprotein modulating drug permeability in Chinese hamster ovary cell mutants.

TL;DR: Observations on the molecular basis of pleiotropic drug resistance are interpreted in terms of a model wherein certain surface glycoproteins control drug permeation by modulating the properties of hydrophobic membrane regions.

Targeting multidrug resistance in cancer

TL;DR: Various approaches to combating multidrug-resistant cancer are described, including the development of drugs that engage, evade or exploit efflux by ABC transporters.
