Multivariate analysis and extraction of parameters in resistive RAMs using the Quantum Point Contact model
A multivariate analysis of the parameters that characterize the reset process in RRAMs has been performed. The different correlations obtained can help to shed light on the current components that contribute in the Low Resistance State (LRS) of the technology considered. In addition, a screening method for the Quantum Point Contact (QPC) current component is presented. For this purpose the second derivative of the current has been obtained using a novel numerical method which allows determining the QPC model parameters. Once the procedure is completed, a whole RS series of thousands of curves is studied by means of a genetic algorithm. The extracted QPC parameter distributions are characterized in depth to get information about the filamentary pathways associated with LRS in the low voltage conduction regime.Spanish Ministry of Economy and Competitiveness TEC2014-52152-C3-2-R , MTM2013-47929-P (also supported by the FEDER program)IMB-CNM Spanish Ministry of Economy and Competitiveness TEC2014-52152-C3-1-R and TEC2014-54906-JIN (supported by the FEDER program)ENIAC Joint Undertaking-PANACHE project.Spanish ICTS Network MICRONANOFAB
MicroRNA-181a regulates IFN-γ expression in effector CD8+ T cell differentiation
CD8+ T cells are key players in immunity against intracellular infections and tumors. The main cytokine associated with these protective responses is interferon-γ (IFN-γ), whose production is known to be regulated at the transcriptional level during CD8+ T cell differentiation. Here we found that microRNAs constitute a posttranscriptional brake to IFN-γ expression by CD8+ T cells since the genetic interference with the Dicer processing machinery resulted in the overproduction of IFN-γ by both thymic and peripheral CD8+ T cells. Using a gene reporter mouse for IFN-γ locus activity, we compared the microRNA repertoires associated with the presence or absence of IFN-γ expression. This allowed us to identify a set of candidates, including miR-181a and miR-451, which were functionally tested in overexpression experiments using synthetic mimics in peripheral CD8+ T cell cultures. We found that miR-181a limits IFN-γ production by suppressing the expression of the transcription factor Id2, which in turn promotes the Ifng expression program. Importantly, upon MuHV-4 challenge, miR-181a-deficient mice showed a more vigorous IFN-γ+ CD8+ T cell response and were able to control viral infection significantly more efficiently than control mice. These data collectively establish a novel role for miR-181a in regulating IFN-γ-mediated effector CD8+ T cell responses in vitro and in vivo.info:eu-repo/semantics/publishedVersio
Endocannabinoid levels in peripheral blood mononuclear cells of multiple sclerosis patients treated with dimethyl fumarate.
The endocannabinoid system (ECS), a signalling network with immunomodulatory properties, is
a potential therapeutic target in multiple sclerosis (MS). Dimethyl fumarate (DMF) is an approved
drug for MS whose mechanism of action has not been fully elucidated; the possibility exists that its
therapeutic effects could imply the ECS. With the aim of studying if DMF can modulate the ECS, the
endocannabinoids 2-arachidonoylglycerol (2-AG), anandamide (AEA), oleoylethanolamide (OEA)
and palmitoylethanolamide (PEA) were determined by liquid chromatography-mass spectrometry
in peripheral blood mononuclear cells from 21 healthy donors (HD) and 32 MS patients at baseline
and after 12 and 24 months of DMF treatment. MS patients presented lower levels of 2-AG and PEA
compared to HD. 2-AG increased at 24 months, reaching HD levels. AEA and PEA remained stable at
12 and 24 months. OEA increased at 12 months and returned to initial levels at 24 months. Patients
who achieved no evidence of disease activity (NEDA3) presented the same modulation over time as
EDA3 patients. PEA was modulated differentially between females and males. Our results show that
the ECS is dysregulated in MS patients. The increase in 2-AG and OEA during DMF treatment suggests
a possible role of DMF in ECS modulation.post-print1392 K
Neuroprotective effects of insulin-like growth factor II in a mouse model of Parkinson's disease
Progressive degeneration of the nigrostriatal dopaminergic pathway is a core, currently irreversible pathological hallmark of Parkinson’s disease (PD) that leads to a variety of motor and non-motor symptoms. Here, we aimed to study the potential neuroprotective effects of insulin-like growth factor II (IGF-II) in a PD mouse model based on the chronic administration of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine and probenecid (MPTP/p), which induces loss of dopaminergic neurons in the Substantia Nigra pars compacta (SNc). Male C57BL6/J mice (N=36) received a 5-week treatment with MPTP/p (or vehicle) and were co-treated with chronic IGF-II (or saline) from either the beginning of the procedure (plus an additional week, days 1-44) or once the MPTP/p insult was already triggered (days 21-44). Baseline and post-treatment measurements for motor performance in the Rotarod and self-grooming in an Open Field were taken. Likewise, dopaminergic (TH, DAT) and neuroinflammatory-related (GFAP) markers in the SNc and the dorsal striatum were studied by immunohistochemistry. Our results revealed that both early and delayed IGF-II co-treatment were successful in preventing motor and behavioral impairment in the MPTP/p model. Moreover, chronic IGF-II protected against MPTP/p-induced loss of dopaminergic neurons in the SNc and promoted a significant recovery of dopaminergic activity in the terminals located in the dorsal striatum, further reducing reactive astrocytosis in these brain regions. Thus, we demonstrated the neuroprotective role of IGF-II in a mouse model of PD, highlighting its potential as a promising therapeutical target for treating this disease.

The Interplay of Mitochondrial Oxidative Stress and Endoplasmic Reticulum Stress in Cardiovascular Fibrosis in Obese Rats
We have evaluated the role of mitochondrial oxidative stress and its association with endoplasmic reticulum (ER) stress activation in the progression of obesity-related cardiovascular fibrosis. MitoQ (200 µM) was orally administered for 7 weeks to male Wistar rats that were fed a high-fat diet (HFD, 35% fat) or a control diet (CT, 3.5% fat). Obese animals presented cardiovascular fibrosis accompanied by increased levels of extracellular matrix proteins and profibrotic mediators. These alterations were associated with ER stress activation characterized by enhanced levels (in heart and aorta vs. CT group, respectively) of immunoglobulin binding protein (BiP; 2.1-and 2.6-fold, respectively), protein disulfide-isomerase A6 (PDIA6; 1.9-fold) and CCAAT-enhancer-binding homologous protein (CHOP; 1.5- and 1.8-fold, respectively). MitoQ treatment was able to prevent (p < 0.05) these modifications at cardiac and aortic levels. MitoQ (5 nM) and the ER stress inhibitor, 4-phenyl butyric acid (4 µM), were able to block the prooxidant and profibrotic effects of angiotensin II (Ang II, 10−6 M) in cardiac and vascular cells. Therefore, the data show a crosstalk between mitochondrial oxidative stress and ER stress activation, which mediates the development of cardiovascular fibrosis in the context of obesity and in which Ang II can play a relevant role
Association of HLA-B*41:02 with Henoch-Schönlein Purpura (IgA Vasculitis) in Spanish individuals irrespective of the HLA-DRB1 status
INTRODUCTION:
To determine whether the human leukocyte antigen (HLA) B alleles are implicated in the susceptibility to Henoch-Schönlein purpura (HSP) in the largest series of Caucasian HSP patients ever assessed for genetic studies.
METHODS:
The study population was composed of 349 Spanish patients diagnosed with HSP fulfilling the American College of Rheumatology and the Michel et al. classification criteria, and 335 sex and ethnically matched controls. HLA-B phenotypes were determined by sequencing-based typing (SBT) and analyzed by chi-square or Fisher exact test.
RESULTS:
A statistically significant increase of HLA-B*41:02 allele in HSP patients when compared with controls was found (8.3% versus 1.5% respectively; p = 0.0001; OR (odds ratio) =5.76 [2.15-19.3]). These results remained statistically significant after adjusting for Bonferroni correction (p = 0.0028). An internal validation also confirmed the susceptibility effect on HSP associated with HLA-B*41:02 (OR = 5.70 [1.98-16.44]). Since a former study described an association between HLA-DRB1*01:03 and HSP susceptibility, we also evaluated the implication of HLA-B*41:02 independently of HLA-DRB1*01:03. Interestingly, the association remained statistically significant (p = 0.0004, OR = 4.97 [1.8-16.9]). No HLA-B association with specific HSP clinical features was found.
CONCLUSIONS:
Our study indicates that HLA-B*41:02 is associated with the susceptibility to HSP in Spanish patients irrespective of HLA-DRB1 status
