Genetic Regulation of Fluxes: Iron Homeostasis of Escherichia coli [PDF]

open access: yesarXiv, 2006
Iron is an essential trace-element for most organisms. However, because high concentration of free intracellular iron is cytotoxic, cells have developed complex regulatory networks that keep free intracellular iron concentration at optimal range, allowing the incorporation of the metal into iron-using enzymes and minimizing damage to the cell. We built

A nanoelectrode array for obtaining intracellular recordings from thousands of connected neurons

open access: yesNature Biomedical Engineering, 2019
Current electrophysiological or optical techniques cannot reliably perform simultaneous intracellular recordings from more than a few tens of neurons.

KMT2A degradation is observed in decitabine‐responsive acute lymphoblastic leukemia cells

open access: yesMolecular Oncology, EarlyView.
We demonstrate that decitabine (DEC) not only degrades the DNA methyltransferase DNMT1 but also the leukemic driver lysine methyltransferase KMT2A likely due to structural similarity of the DNA‐binding CXXC domains. DEC influences KMT2A downstream processes and synergizes with menin inhibitor revumenib (REV) to decrease leukemic cell proliferation, and

Towards a systemic understanding of Listeria monocytogenes metabolism during infection

open access: yesFrontiers in Microbiology, 2012
Listeria monocytogenes is a foodborne human pathogen that can cause invasive infection in susceptible animals and humans. For proliferation within hosts, this facultative intracellular pathogen uses a reservoir of specific metabolic pathways, transporter

Effect of intracellular diffusion on current-voltage curves in potassium channels [PDF]

open access: yesDiscrete and Continuous Dynamical System Series B, 19, 1837-1853, 2014, 2012
We study the effect of intracellular ion diffusion on ionic currents permeating through the cell membrane. Ion flux across the cell membrane is mediated by special proteins forming specific channels. The structure of potassium channels have been widely studied in recent years with remarkable results: very precise measurements of the true current across

High energy-charged cell factory for heterologous protein synthesis [PDF]

open access: yes, 2009
Overexpression of gluconeogenic phosphoenolpyruvate carboxykinase (PCK) under glycolytic conditions enables Escherichia coli to maintain a greater intracellular ATP concentration and, consequently, to up-regulate genes for amino acid and nucleotide ...

Polyfunctional CD8+CD226+RUNX2hi effector T cells are diminished in advanced stages of chronic lymphocytic leukemia

open access: yesMolecular Oncology, EarlyView.
CD226+CD8+ T cells express elevated levels of RUNX2, exhibit higher proliferation capacity, cytokines and cytolytic molecules expression, and migratory capacity. In contrast, CD226−CD8+ T cells display an exhausted phenotype associated with the increased expression of co‐inhibitory receptors and impaired effector functions.

ROLE OF BIOLOGICAL PROPERTIES OF CORYNEBACTERIA IN ASSOCIATIVE SYMBIOSIS

open access: yesЖурнал микробиологии, эпидемиологии и иммунобиологии, 2015
Microorganisms of the Corynebacterium genus are examined in the review as a component of a single microecological system of humans in the context of their interaction with the macroorganism, dominant and associative microorganisms under the conditions of

Intracellular Antibody Immunity

open access: yesJournal of Clinical Immunology, 2014
Antibodies allow the immune system to target pathogens despite their tremendous diversity and rapid evolution. Once bound to a pathogen, antibodies induce a broad range of effector mechanisms, including phagocytosis and complement. However, these mechanisms are all initiated in the extracellular space, meaning that pathogens like viruses evade them ...

Two intracellular and cell type-specific bacterial symbionts in the placozoan Trichoplax H2

open access: yes, 2019
Placozoa is an enigmatic phylum of simple, microscopic, marine metazoans(1,2). Although intracellular bacteria have been found in all members of this phylum, almost nothing is known about their identity, location and interactions with their host(3-6). We
