Molecular Mechanisms Used by Salmonella to Evade the Immune System [PDF]

, 2017
Human and animal pathogens are able to circumvent, at least temporarily, the sophisticated immune defenses of their hosts. Several serovars of the Gram-negative bacterium Salmonella enterica have been used as models for the study of pathogen-host ...

Senescent thyrocytes and thyroid tumor cells induce M2-like macrophage polarization of human monocytes via a PGE2-dependent mechanism

Journal of Experimental & Clinical Cancer Research, 2019
Background Thyroid carcinoma includes several variants characterized by different biological and clinical features: from indolent microcarcinoma to undifferentiated and aggressive anaplastic carcinoma. Inflammation plays a critical role in thyroid tumors.

A new microtubule-stabilizing agent shows potent antiviral effects against African swine fever virus with no cytotoxicity

Emerging Microbes and Infections, 2021
African swine fever virus (ASFV) is the causal agent of a fatal disease of domestic swine for which no effective antiviral drugs are available. Recently, it has been shown that microtubule-targeting agents hamper the infection cycle of different viruses.

Molecular model of a sensor of two-component signaling system

Scientific Reports, 2021
Two-component systems (TCS) are widespread signaling systems present in all domains of life. TCS typically consist of a signal receptor/transducer and a response regulator.

Mechanisms of decoherence in weakly anisotropic molecular magnets

, 2000
Decoherence mechanisms in crystals of weakly anisotropic magnetic molecules, such as V15, are studied. We show that an important decohering factor is the rapid thermal fluctuation of dipolar interactions between magnetic molecules. A model is proposed to

Morphological plasticity of astroglia: Understanding synaptic microenvironment [PDF]

, 2015
Memory formation in the brain is thought to rely on the remodeling of synaptic connections which eventually results in neural network rewiring. This remodeling is likely to involve ultrathin astroglial protrusions which often occur in the immediate ...

On the molecular mechanisms of transposition. [PDF]

Proceedings of the National Academy of Sciences, 1981
We present a model for transposition that allows a choice between cointegrate formation (replicon fusion) and direct transposition. We propose that initiation of the process occurs by invasion of the target DNA by a single-stranded end of the transposable element.

Hypoxia- and MicroRNA-Induced Metabolic Reprogramming of Tumor-Initiating Cells

Cells, 2019
Colorectal cancer (CRC), the second most common cause of cancer mortality in the Western world, is a highly heterogeneous disease that is driven by a rare subpopulation of tumorigenic cells, known as cancer stem cells (CSCs) or tumor-initiating cells ...
