Antibiotic Resistance Antibiotic resistance is an alarming and growing challenge. Bacteria show great heterogeneity in growth and mutation rates. Such variability allows some cells to persist during transient antibiotic exposure. During this persistent phase, mutations accumulate, which can result in selection for full-blown antibiotic resistance.

Plant pathogens belonging to the genus Erwinia cause diseases in several economically important plants. Plants respond to bacterial infection with a powerful chemical arsenal and signaling molecules to rid themselves of the microbes. Although our understanding of how Erwinia initiate infections in plants has become clear, a comprehensive understanding ...

Mycobacterial efflux pumps and chemotherapeutic implications
International Journal of Antimicrobial Agents, 2003The demonstration of the existence of active efflux pumps in mycobacteria raises the question of whether or not these can increase in number and activity rendering wild-type mycobacteria increasingly resistant to a given antibiotic. This could be a mechanism by which mutated resistant strains become better fit to the selective environment ...

New-generation efflux pump inhibitors
Expert Review of Clinical Pharmacology, 2008The development of novel efflux pump inhibitors is an emerging and challenging research field. Besides the use of such excipients in cancer therapy, efflux pump inhibitors are gaining increasing interest with regards to drug delivery. In particular, inhibition of efflux pumps located in the intestine and the blood-brain barrier offers promising ...

Inhibition of the multidrug resistance efflux pump
Biochimica et Biophysica Acta (BBA) - Reviews on Biomembranes, 1993An ATP-dependent efflux pump is found in the plasma membrane of certain multidrug resistant (MDR) cancer cells. Drug resistance is due to decreased intracellular drug levels that have been reduced to subcytotoxic concentrations. Inhibition of the MDR efflux pump with a reversal agent may 'trap' the cytotoxic drug inside the cell; thus, cellular drug ...

Current Microbiology, 2009
In gram negative bacteria, fluoroquinolone resistance is acquired by target mutations in topoisomerase genes or by reducing the permeation of drugs due to the increase in expression of endogenous multidrug efflux pumps that expel structurally unrelated antimicrobial agents.

Efflux pump activity in Enchytraeidae
2019Enchytraeids are ecologically relevant soil organisms, which play an important role in organic matter decomposition and soil bioturbation. They live in close contact with the pore water fraction of soil which makes them vulnerable to xenobiotics exposure.

Multidrug-resistant bacteria are a major public health threat. MDR efflux pump overexpression and enzymatic changes are major antibiotic resistance mechanisms. Many drug and biofilm resistance strategies involve efflux pumps. Natural substrate and inhibitor identification is a new study. Efflux pump inhibition allows medication buildup inside bacterial

Cholestasis and the Role of Basolateral Efflux Pumps
Zeitschrift für Gastroenterologie, 2011ATP-dependent transport of biliary constituents, such as bile acids, reduced glutathione, and bilirubin glucuronosides across the hepatocyte canalicular membrane into bile represents the decisive driving force for the formation of biliary fluid. Functional characterization, cloning, and localization of hepatocellular transporter proteins has provided a

Efflux pump inhibitors in bacteria
Expert Opinion on Therapeutic Patents, 2007The efficacy of antibiotherapy of infectious diseases is strongly compromised by the advent and spread of antibiotic resistance. Active efflux of cytotoxic drugs mediated by multi-drug transporters is the basis of multi-drug resistance in prokaryotic cells.
