RESUMEN

Background: Major depression disorder (MDD) and anxiety are common mental disorders that significantly affect the quality of life of those who suffer from them, altering the person's normal functioning. From the biological perspective, the most classical hypothesis explaining their occurrence relies on neurotransmission and hippocampal excitability alterations. However, around 30% of MDD patients do not respond to medication targeting these processes. Over the last decade, the involvement of inflammatory responses in depression and anxiety pathogenesis has been strongly acknowledged, opening the possibility of tackling these disorders from an immunological point of view. In this context, regulatory T cells (Treg cells), which naturally maintain immune homeostasis by suppressing inflammation could be promising candidates for their therapeutic use in mental disorders. Methods: To test this hypothesis, C57BL/6 adult male mice were submitted to classical stress protocols to induce depressive and anxiety-like behavior; chronic restriction stress (CRS), and chronic unpredictable stress (CUS). Some of the stressed mice received a single adoptive transfer of Treg cells during stress protocols. Mouse behavior was analyzed through the open field (OFT) and forced swim test (FST). Blood and spleen samples were collected for T cell analysis using cell cytometry, while brains were collected to study changes in microglia by immunohistochemistry. Results: Mice submitted to CRS and CUS develop anxiety and depressive-like behavior, and only CRS mice exhibit lower frequencies of circulating Treg cells. Adoptive transfer of Treg cells decreased anxiety-like behavior in the OFT only in CRS model, but not depressive behavior in FST in neither of the two models. In CRS mice, Treg cells administration lowered the number of microglia in the hippocampus, which increased due this stress paradigm, and restored its arborization. However, in CUS mice, Treg cells administration increased microglia number with no significant effect on their arborization. Conclusion: Our results for effector CD4+ T cells in the spleen and microglia number and morphology in the hippocampus add new evidence in favor of the participation of inflammatory responses in the development of depressive and anxiety-like behavior and suggest that the modulation of key immune cells such as Treg cells, could have beneficial effects on these disorders.

RESUMEN

INTRODUCCIÓN. Los estudios de tratamiento indican que el riesgo de transición a un trastorno psicótico puede al menos retrasarse en la población clínica de alto riesgo de psicosis (CHR), además de mejorar variables relacionadas con la calidad de vida de los pacientes, existiendo evidencia a favor de la terapia cognitivo conductual (TCC). MÉTODOS. Se realizó una síntesis narrativa, basada en la búsqueda de artículos originales, que abordasen la efectividad de la TCC en pacientes CHR, publicados en los últimos cinco años, incluidos en esta síntesis. RESULTADOS. Se incluyeron un total de 10 artículos que evalúan la TCC en CHR, siendo un tratamiento efectivo y ampliamente utilizado, lo que se asocia a una disminución en las consecuencias psicosociales que conlleva el retraso en la presentación del cuadro clínico y/o la disminución de síntomas comórbidos. CONCLUSIÓN. Actualmente, la TCC se ha convertido en el tratamiento de primera elección para CHR, existiendo una gran variedad de estrategias psicoterapéuticas específicas dentro de este grupo de intervención.

INTRODUCTION. Treatment studies indicate that the risk of transition to a psychotic disorder can at least be delayed in the clinical population at high risk for psychosis (CHR), in addition to improving variables related to the quality of life of patients, with evidence in favor of cognitive behavioral therapy (CBT). METHODS. A narrative synthesis was carried out, based on the search for original articles, which addressed the effectiveness of CBT in CHR patients, published in the last five years, included in this synthesis. RESULTS. A total of 10 articles that evaluate CBT in CHR were included, being an effective and widely used treatment, which is associated with a decrease in the psychosocial consequences that the delay in the presentation of the clinical picture and/or the decrease in symptoms entails. comorbid. CONCLUSION. Currently, CBT has become the treatment of first choice for CHR, with a wide variety of specific psychotherapeutic strategies within this intervention group.

RESUMEN

Exosomes derived from glial cells such as astrocytes, microglia, and oligodendrocytes can modulate cell communication in the brain and exert protective or neurotoxic effects on neurons, depending on the environmental context upon their release. Their isolation, characterization, and analysis under different conditions in vitro, in animal models and samples derived from patients has allowed to define the participation of other molecular mechanisms behind neuroinflammation and neurodegeneration spreading, and to propose their use as a potential diagnostic tool. Moreover, the discovery of specific molecular cargos, such as cytokines, membrane-bound and soluble proteins (neurotrophic factors, growth factors, misfolded proteins), miRNA and long-non-coding RNA, that are enriched in glial-derived exosomes with neuroprotective or damaging effects, or their inhibitors can now be tested as therapeutic tools. In this review we summarize the state of the art on how exosomes secretion by glia can affect neurons and other glia from the central nervous system in the context of neurodegeneration and neuroinflammation, but also, on how specific stress stimuli and pathological conditions can change the levels of exosome secretion and their properties.

RESUMEN

El síndrome genitourinario de la menopausia se refiere a los signos y síntomas relacionados a la disminución estrogénica dando como resultado una atrofia vaginal, esto ocasiona un gran impacto negativo en las actividades cotidianas de las mujeres, existen varios tratamientos para aliviar y resolver los síntomas, siendo los más frecuentes la incontinencia urinaria por esfuerzo y resequedad vaginal. Dentro de los distintos tratamientos, el láser tiene como objetivo la restauración de la mucosa vaginal, estimulando los fibroblastos para obtener la neo colagenogenesis y vascularización, recuperando su funcionalidad y obteniendo mejoría de los síntomas junto con la calidad de vida de las pacientes

Genitourinary syndrome of menopause refers to a group of signs and symptoms related to the decreased estrogen and as a result, the vaginal atrophy, this has a great negative impact on the daily activities of women, there are several treatments to alleviate and resolve the symptoms, the most frequent being stress urinary incontinence and vaginal dryness. Among the different treatments, the laser aims to restore the aavaginal mucosa, stimulating fibroblasts to obtain neo-collagen oogenesis and revascularization, recovering their functionality and obtaining an improvement in symptoms along with the quality of life of patients
