Memory CD8+ T Cell Protection From Viral Reinfection Depends on Interleukin-33 Alarmin Signals
2019
Memory CD8+ cytotoxic T lymphocytes (CTLs) can protect against viral reinfection. However, the signals driving rapid memory CTL reactivation have remained ill-defined. Viral infections can trigger the release of the alarmin interleukin-33 (IL-33) from non-hematopoietic cells. IL-33 signals through its unique receptor ST2 to promote primary effector expansion and activation of CTLs. Here, we show that the transcription factor STAT4 regulated the expression of ST2 on CTLs in vitro and in vivo in primary infections with lymphocytic choriomeningitis virus (LCMV). In the primary antiviral response, IL-33 enhanced effector differentiation and antiviral cytokine production in a CTL-intrinsic manne…
Les lieux de mémoire victimaire en Europe : une culture commune et concurrente
2020
Since the 1990s, memorials and museums devoted to the victims of the massacres perpetrated in the twentieth century have multiplied in Europe, then in the world. This social, political and cultural fact is new. It reveals a radical change in historical representation where for centuries, only the victorious hero was celebrated in official history. In this context, specific memory sites, called “victim memory places”, have emerged. The Second World War is the turning point in this history of memory. The memory of the Holocaust is the model. But other memories, often competing, have also developed recently.This study proposes to record this break in the long duration of the history. Where doe…
Staging, neurocognition and social functioning in bipolar disorder.
2018
Introduction: Bipolar disorder (BD) is associated with significant neurocognitive and functional impairment, which may progress across stages. The ‘latent stage' of BD remains understudied. This cross-sectional study assessed staging, neurocognition and social functioning among BD patients and their healthy siblings.Methods: Four groups were included: euthymic type I BD patients in the early (n = 25) and late (n = 23) stages, their healthy siblings (latent stage; n = 23) and healthy controls (n = 21). All 92 subjects underwent a comprehensive neuropsychological battery of processing speed, verbal learning/memory, visual memory, working memory, verbal fluency, executive cognition, and motor …
Semantic processing in children with autism spectrum disorder
2021
El presente estudio analizó el procesamiento semántico de un grupo de niños con trastorno del espectro autista (n= 24), con el objetivo principal de averiguar si presentan diferencias en comparación con un grupo de niños con desarrollo típico (n = 24). Para ello, se realizó un análisis del contenido de los ítems del subtest de información del WPPSY-III, estableciendo una serie de categorías en función del tipo de demanda semántica requerida: asociación significante-significado, relación experiencial y conocimiento general. Los resultados obtenidos apoyan la idea de que los niños con autismo realizarían un procesamiento semántico de la información de la misma manera que los niños sin autismo…
Pamięć i język w kontekście dyskursywnego konstruowania śląskiej tożsamości zbiorowej na przełomie XVIII i XIX wieku
2018
The aim of this paper is to answer why collective memory should be taken into account in the linguistic discursive analysis of the Silesian collective identity construction, presented in the periodical entitled "Schlesische Provinzialblätter". Starting with the historical background of the periodical and making references to cultural and sociological studies related to collective identity, the author attemptes to identify the role played by collective memory in identity-building discourses and presents methodological propositions for a linguistic depiction of this phenomenon.
Dopamine Related Genes Differentially Affect Declarative Long-Term Memory in Healthy Humans
2020
In humans, monetary reward can promote behavioral performance including response times, accuracy, and subsequent recognition memory. Recent studies have shown that the dopaminergic system plays an essential role here, but the link to interindividual differences remains unclear. To further investigate this issue, we focused on previously described polymorphisms of genes affecting dopaminergic neurotransmission: DAT1 40 base pair (bp), DAT1 30 bp, DRD4 48 bp, and cannabinoid receptor type 1 (CNR1). Specifically, 669 healthy humans participated in a delayed recognition memory paradigm on two consecutive days. On the first day, male vs. female faces served as cues predicting an immediate moneta…
Frammenti di biografie plurali
2022
Ritorno a Palermo dopo tredici anni trascorsi in Umbria. Anni importanti in cui ho frequentato l’università laureandomi in filosofia e conseguendo un dottorato di ricerca; indagando sui temi del disagio psichico e della crisi della presenza in De Martino; sotto la guida di Tullio Seppilli, che di De Martino era stato allievo e il cui rigore nella ricerca è stato per me un esempio indimenticabile. Scappata a diciotto anni da una terra che mi aveva schiacciata con la sua violenza. In primo luogo sul versante privato. Una gelida brutalità di cui – quando sono andata via, determinata a non tornare – non percepivo fino in fondo i risvolti sul piano politico e della limitazione degli spazi fisici…
Audiovisual processing of Chinese characters elicits suppression and congruency effects in MEG
2019
Learning to associate written letters/characters with speech sounds is crucial for reading acquisition. Most previous studies have focused on audiovisual integration in alphabetic languages. Less is known about logographic languages such as Chinese characters, which map onto mostly syllable-based morphemes in the spoken language. Here we investigated how long-term exposure to native language affects the underlying neural mechanisms of audiovisual integration in a logographic language using magnetoencephalography (MEG). MEG sensor and source data from 12 adult native Chinese speakers and a control group of 13 adult Finnish speakers were analyzed for audiovisual suppression (bimodal responses…
Beta-band MEG signal power changes in older adults after physical exercise program with and without additional cognitive training
2023
Physical exercise has been considered to be an efficient mean of preserving cognitive function and it influences both the structural and functional characteristics of the brain. It has especially been shown to increase brain plasticity, the capacity to re-structure brain properties in response to interaction, such as cognitive practice. Studies have also examined the potential additive effect of cognitive training on the documented benefit of physical exercise, commonly, however, not at the neural level. We monitored, using magnetoencephalography (MEG), the brain processes associated with executive functions in older individuals who participated in a 12-month randomized controlled trial inc…
Change in body image among depressed adult outpatients after a dance movement therapy group treatment
2018
Abstract This study reports on the body image of depressed psychiatric outpatients, and the impact thereon of a dance movement therapy (DMT) group. Body image is perceived as a tri-partite construct consisting of image-properties, body-self, and body memory. Depressed patients in an outpatient mental health service participated in a DMT group treatment consisting of twelve 90-min long sessions in groups of 4–7 patients. Patients (N = 18) responded to a structured Body Image Assessment (BIA) before and after the treatment. Initially, the depressed patients’ body image was characterized by fragmentation, distortions, and shallowness of body awareness. The DMT group treatment aimed to offer th…
