Is autophagy an elective strategy to protect neurons from dysregulated cholesterol metabolism?

Neural Regeneration Research 2019年第4期14卷 582-587页

The balance of autophagy, apoptosis and necroptosis is crucial to determine the outcome of the cellular response to cholesterol dysregulation. Cholesterol plays a major role in regulating the properties of cell membranes, especially as regards their fluidity, and the regulation of its biosynthesis influences the shape and functions of these membranes. Whilst dietary cholesterol can easily be distributed to most organs, the central nervous system, whose membranes are particularly rich in cholesterol, mainly relies on de novo synthesis. For this reason, defects in the biosynthesis of cholesterol can variably affect the development of central nervous system. Moreover, defective synthesis of cholesterol and its intermediates may reflect both on structural cell anomalies and on the response to inflammatory stimuli. Examples of such disorders include mevalonate kinase deficiency, and Smith-Lemli-Opitz syndrome, due to deficiency in biosynthetic enzymes, and type C Niemann-Pick syndrome, due to altered cholesterol trafficking across cell compartments. Autophagy, as a crucial pathway dedicated to the degradation of cytosolic proteins and organelles, plays an essential role in the maintenance of homeostasis and in the turnover of the cytoplasmic material especially in the presence of imbalances such as those resulting from alteration of cholesterol metabolism. Manipulating the process of autophagy can offer possible strategies for improving neuronal cell viability and function in these genetic disorders.

Genetics of inflammatory bowel disease from multifactorial to monogenic forms

引用

World Journal of Gastroenterology 2015年第43期21卷 12296-12310页

作者： Anna Monica Bianco Martina Girardelli Alberto tommasini Institute for Maternal and Child Health-IRCCS "Burlo Garofolo"

Inflammatory bowel disease(IBD) is a group of chronic multifactorial disorders. According to a recent study,the number of IBD association loci is increased to 201,of which 37 and 27 loci contribute specifically to the development of Crohn's disease and ulcerative colitis respectively. Some IBD associated genes are involved in innate immunity,in the autophagy and in the inflammatory response such as NOD2,ATG16L1 and IL23 R,while other are implicated in immune mediated disease(STAT3) and in susceptibility to mycobacterium infection(IL12B). In case of early onset of IBD(VEO-IBD) within the 6th year of age,the disease may be caused by mutations in genes responsible for severe monogenic disorders such as the primary immunodeficiency diseases. In this review we discuss how these monogenic disorders through different immune mechanisms can similarly be responsible of VEO-IBD phenotype. Moreover we would highlight how the identification of pathogenic genes by Next Generation Sequencing technologies can allow to obtain a rapid diagnosis and to apply specific therapies.

An important criterion for reliable multi-monochromatic x-ray imager diagnostics and its impact on the reconstructed images

引用

High Power Laser Science and Engineering 2015年第3期3卷 59-65页

作者： T.Nagayama R.C.Mancini D.Mayes R.tommasini R.Florido Physics Department University of Nevada Lawrence Livermore National Laboratory Departamento de Física Universidad de Las Palmas de Gran Canaria

Temperature and density asymmetry diagnosis is critical to advance inertial confinement fusion(ICF) science. A multimonochromatic x-ray imager, MMI, records the spectral signature from an ICF implosion core with time resolution, 2D spatial resolution and spectral resolution. While narrow-band images and 2D space-resolved spectra from the MMI data constrain the temperature and the density spatial structure of the core, the accuracy of the images and the spectra highly depends on the quality of the MMI data and the processing tools. Here, we synthetically investigate the criterion for reliable MMI diagnostics and its effects on the accuracy of the reconstructed images. The pinhole array tilt determines the object spatial sampling efficiency and the minimum reconstruction width, w. When the spectral width associated with w is significantly narrower than the spectral linewidth, the line images reconstructed from the MMI data become reliable. The MMI setup has to be optimized for every application to meet this criterion for reliable ICF diagnostics.

Heterozygous nucleotide-binding oligomerization domain-2 mutations affect monocyte maturation in Crohn's disease

引用

World Journal of Gastroenterology 2007年第46期13卷 6191-6196页

作者： Marilena Granzotto Elisa Fabbro Massimo Maschio Stefano Martelossi Sara Quaglia Alberto tommasini Gianni Presani Alessandro Ventura Institute for Child Health Burlo Garofolo Trieste 34137Italy Department of Sciences of Reproduction and Development University of TriesteTriesteItaly Supported by the Italian Ministry of HealthNo.150/03

AIM： To investigate the function of monocytes in Crohn＇s disease （CD） patients and to correlate this with disease- associated nucleotide-binding oligomerization domain-2 （NOD2） gene variants. METHODS： Monocytes from 47 consecutively referred CD patients and 9 healthy blood donors were cultured with interleukin （IL）-4 and granulocyte-macrophage colony-stimulating factor （GM-CSF）, and stimulated with lipopolysaccharide （LPS） or muramyldipeptide （MDP）, the putative ligand of NOD2. RESULTS： We found that monocytes from CD patients differentiated in vitro to mature dendritic cells （DCs）, as determined by immunophenotype and morphology. IVOD2 genotype was assessed in all subjects, and we observed high CD86 expression on immature and LPS-stimulated DCs in IVOD2 mutated CD patients, as compared with wtlVOD2 CD patients and controls. By contrast, CD86 expression levels of DCs induced to maturity with MDP derived from IVOD2-mutated subjects were comparable to those of normal subjects. The amount of IL-12p70 in patient-cell cultures was larger than in controls aEer LPS treatment, but not aEer treatment with MDR CONCLUSION： Our results suggest that DCs obtained from patients with mutations in the IVOD2 gene display an activated phenotype characterized by high CD86 expression, but have a diminished response to MDP when compared to the terminal differentiation phase. We speculate that the altered differentiation of monocytes might lead to an imbalance between inflammation and the killing ability of monocytes, and may be relevant to the pathogenesis of CD.

Using music to reduce anxiety among older adults in the emergency department:a randomized pilot study

引用

Journal of Integrative Medicine 2017年第6期15卷 450-455页

作者： laura Belland laura Rivera-Reyes Ula Hwang center for family medicine newyork-presbyterian/columbia university medical centerNew YorkNY 10032USA department of emergency medicine icahn school of medicine at mount sinaiNew YorkNY 10029USA geriatric research education and clinical centerjames j.peters vamcNew YorkNY 10029USA

BACKGROUND： An emergency department （ED） visit may be distressing and anxiety-provoking for older adults （age 〉 65 years）. No studies have specifically evaluated the effect of music listening on anxiety in older adults in the ED. OBJECTIVE： The objective of this pilot study was to evaluate the effect of music listening on anxiety levels in older ED patients. DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS： This was a randomized pilot study in the geriatric ED of an urban academic tertiary medical center. This was a sample of English-speaking adults （age 〉 65 years） who were not deaf （n = 35）. Subjects consented to participate and were randomized to receive up to 60 min of music listening with routine care, while the control group received routine care with no music. Subjects in the music treatment group received headphones and an electronic tablet with pre-downloaded music, and were allowed to choose from 5 selections. MAIN OUTCOME MEASURES： The primary outcome was change in anxiety levels, measured by the state- trait anxiety inventory （STAI）, at enrollment and 1 h later. RESULTS： A total of 35 participants were enrolled： 74% were female, 40% were white, and 40% were black; of these, 32 subjects completed the study protocol. When comparing control （n = 18） against intervention subjects （n = 17）, there were no significant differences in enrollment STAI scores （43.00 ± 15.00 vs. 40.30± 12.80, P = 0.57）. STAI scores 1 hour after enrollment （after the music intervention） were significantly reduced in the intervention subjects compared to the control subjects （with reduction of 10.00± 12.29 vs. 1.88 ± 7.97, P = 0.03）. CONCLUSION： These pilot results suggest that music listening may be an effective tool for reducing anxiety among older adults in the ED.

Galectin-3 (Gal-3) in oligodendrocyte (OLG) differentiation: OLGs are the cells in charge of myelination in the central nervous system (CNS), allowing rapid conduction of the neural action potential and giving trophic support to axons. OLGs undergo a series of changes throughout their life cycle: first, upon neural stem cell comm让ment to the OLG lineage, cells referred to as OLG precursor cells (OPC) present a bipolar morphology, have proliferative and migratory capacity and express molecular markers like platelet-derived growth factor receptor alpha and neural/glial antigen 2.
