This review summarizes research progress in the pathophysiological pathogenesis of rosacea.

Role of autonomic nerves in immune imbalance in atopic dermatitis / 中华皮肤科杂志

The skin is rich in nerve terminals, among which autonomic nerves closely interact with keratinocytes and immune cells. The autonomic nerves are critical to skin physiological function. Patients with atopic dermatitis exhibit reduced autonomic innervation, accompanied by autonomic nerve dysfunction such as sweating disorder. Restoration of autonomic neurological function can ameliorate atopic dermatitis. This review summarizes the structure and physiological function of skin autonomic nerves, autonomic neurological abnormalities in atopic dermatitis, and possible therapeutic strategies.

Lowered serum cesium levels in schizophrenia: association with immune-inflammatory biomarkers and cognitive impairments

Objectives: A previous study has shown that schizophrenia (SCZ) is accompanied by lowered levels of trace/metal elements, including cesium. However, it is not clear whether changes in cesium, rubidium, and rhenium are associated with activated immune-inflammatory pathways, cognitive impairments, and the symptomatology of SCZ. Methods: This study measured cesium, rubidium, and rhenium, cognitive impairments (using the Brief Assessment of Cognition in Schizophrenia [BACS]), and the levels of cytokines/chemokines interleukin (IL)-1β, tumor necrosis factor (TNF)-α, and eotaxin (CCL11) in 120 patients with SCZ and 54 healthy controls. Severity of illness was assessed using the Brief Psychiatric Rating Scale (BPRS), the Scale for the Assessment of Negative Symptoms (SANS), the Fibromyalgia and Chronic Fatigue Syndrome Rating (FF) Scale, and the Hamilton Depression Rating Scale (HAM-D). Results: Serum cesium was significantly lower in patients with SCZ as compared with controls. Further, serum cesium was significantly and inversely associated with CCL11 and TNF-α, but not IL-1β, in patients with SCZ; significant inverse associations were also noted between serum cesium levels and BPRS, FF, HAM-D, and SANS scores. Finally, cesium was positively correlated with neurocognitive probe results including the Tower of London, Symbol Coding, Controlled Word Association, Category Instances, Digit Sequencing Task, and List Learning tests. Conclusion: The results suggest that lowered serum cesium levels may play a role in the pathophysiology of SCZ, contributing to specific symptom domains including negative, depressive and fatigue symptoms, neurocognitive impairments (spatial working, episodic, and semantic memory and executive functions), and neuroimmune pathways.

Neurobiological mechanism of post-stroke depression / 国际脑血管病杂志

Post-stroke depression (PSD) is one of the common complications of stroke, which can seriously affect the functional rehabilitation of patients with stroke and increase their mortality and disability rate. As for the pathogenesis of PSD, endogenous theory emphasizes that it is closely associated with biological mechanism, while reactive theory believes that it is associated with psychosocial factors. At present, the research on the pathogenesis and treatment of PSD focuses on inflammation, immune response, stress, nerve regeneration, brain network, biological rhythm disorder, sleep disorder, melatonin and so on. This article reviews the research progress on the neurobiological mechanism of PSD and the related treatment for the pathogenesis.

Research progress on neuroimmune in allergy diseases / 解放军医学杂志

Recent studies have revealed that the interactions of nervous and immune system play a role in the advancement of allergy diseases. Allergy diseases are the consequence of an aberrant response from the immune system to foreign substances and harmful stimuli, have high incidence and the related allergic symptoms seriously affect the patient's quality of life. Specific immune mediator receptors [such as type 1 histamine receptors (H1R), protease activating receptor 2 (PAR-2), tropomyosin receptor kinase A (TrkA)] may be expressed on the surface of neurons and nerve fibers of the nervous system, while neuropeptide receptors [such as neurokinin receptor-1 (NK-1R), vasoactive intestinal peptide receptor (VPAC)] and neurotransmitter receptors [such as α7 acetylcholine nicotinoid-like receptor (α7nAChR), Beta 2 adrenergic receptor (β2AR)] may also be expressed on the immune cell membrane in the immune system. Therefore, esthesioneure can be activated by inflammatory mediators secreted by immune cells to conduct sensation and release neuropeptides and neurotransmitters, while the function of immune cells can be regulated by neuropeptides and neurotransmitters from the nervous system. Further understanding the role of neuroimmune in allergic diseases may provide guidance for the treatment of allergic diseases.

Research progress on the relationship between ADSCs and immunomodulatory factors / 天津医药

Mesenchymal stem cells (MSCs) are defined as undifferentiated cells that are capable of self renewal and functionally capable of differentiating into adipocytes, osteoblasts, chondrocytes, hepatocyte-like cells, myogenic-like cells, neuron-like cells, and islet-like cells. MSCs possess immunomodulatory properties according to secrete indoleamine-2, 3-dioxygenase (IDO) and prostaglandin E2 (PGE2) to play the role of immunomodulatory. Moreover, pre-stimulation of interferon-γ (IFN-γ) can promote the immunomodulatory function of MSCs. High abundance of MSCs found in adipose tissue makes it a very attractive source of adult stem cells. This article reviews the recent progress in the interaction between adipose derived mesenchymal stem cells (ADSCs) and three immunomodulatory factors.

Efeito do estresse pré-natal na regulação da inflamação alérgica pulmonar no modelo murino de asma experimental

Devido ao seu rápido crescimento, o feto é particularmente vulnerável a insultos e modificações no millieu hormonal. Este fato sugere que situações adversas experimentadas pela mãe grávida podem alterar o desenvolvimento e a saúde da prole, explicado principalmente pela permeabilidade da barreira placentária a diversos hormônios e substâncias. O objetivo deste trabalho foi estudar o efeito do estresse pré-natal na regulação da inflamação alérgica pulmonar, empregando o modelo murino de asma experimental. Para este propósito foram utilizadas camundongas virgens da linhagem Swiss, com 50 dias de idade. Foi empregado o modelo de choque nas patas para promover o estresse pré-natal e o modelo do "metrô de Nova Efeito do estresse pré-natal na regulação da inflamação alérgica pulmonar no modelo murino de asma experimental 65 Iorque" para o estresse pós-natal. As fêmeas foram distribuídas em 4 grupos experimentais: CC: fêmeas não estressadas; CE: fêmeas estressadas pós-natalmente aos 60 dias de idade (PND60), EC: fêmeas nascidas de mães estressadas entre o dia 15 (GD15) e 18 de gestação (GD18); EE: fêmeas nascidas de mães estressadas entre o GD15 e GD18 e estressadas pós-natalmente aos PND60. A indução da inflamação alérgica pulmonar foi realizada através da sensibilização dos animais com solução de ovalbumina (OVA) 0,1 mg.Kg-1 sc para avaliação do leucograma, lavado broncoalveolar (BAL), celularidade hematopoiética medular e neuroquímica. Os experimentos foram realizados 24h após a última sessão de nebulização. O número de células do BAL foi significantemente maior nos animais do grupo EE, em relação àqueles dos grupos CC (P0.05) para os linfócitos, neutrófilos, eosinófilos e monócitos; porém, observou-se diferenças significativas (P<0.05) entre o número de bastonetes dos grupos, sendo maior nos animais do grupo CC em relação àqueles do grupo EC. O número de células hematopoiéticas da medula óssea foi significantemente (P<0.05) menor nos animais do grupo EE, em relação àqueles do grupo CC. No córtex pré-frontal, há diferenças significantes na relação Ácido Homovanílico/ Dopamina (HVA/DA) (P<0.05), sendo maior nos animais do grupo EC, em relação àqueles do grupo CE. Em conclusão, o estresse pré-natal levou a modulação de células do sistema imune (SI) dos neonatos, evidenciado após a exposição a estresse agudo pós-natal, amplificando a resposta alérgica pulmonar. Sugere-se que a maior susceptibilidade dos animais do grupo EE seja consequência de alterações induzidas pelo estresse pré-natal no eixo hipotálamo-pituitária-adrenal (HPA).

Debido a su rápido crecimiento el feto es particularmente vulnerable a los cambios en el ambiente hormonal. Esto sugiere que situaciones adversas de la madre durante la gestación pueden alterar el desarrollo y la salud de la descendencia, principalmente debido a la permeabilidad de la barrera placentaria a diversas hormonas y sustancias. El objetivo del presente trabajo fue estudiar el efecto del estrés prenatal sobre la regulación de la inflamación alérgica pulmonar, empleando el modelo murino de asma experimental. Para este propósito fueron utilizadas ratonas vírgenes de linaje suizo de 50 d de edad. Fue empleado el modelo de descargas eléctricas en las patas (Footshock) para inducir el estrés prenatal y el modelo de estrés denominado "metro de Nueva York" para el estrés posnatal. Las hembras fueron divididas en 4 grupos experimentales: CC: hembras no estresadas; CE: hembras estresadas posnatalmente a los 60 d de edad (PND60); EC: hembras nacidas de madres estresadas entre el día 15 (GD15) y 18 de gestación (GD18); EE: hembras nacidas de madres estresadas entre el GD15 y GD18 y estresadas posnatalmente al PND60. La inducción de la inflamación alérgica pulmonar fue realizada a través de la sensibilización de los animales con solución de ovoalbúmina (OVA) 0,1 mg.Kg-1 sc. para posteriormente evaluar leucograma, lavado broncoalveolar (BAL), celularidad hematopoyética medular y neuroquímica. Los experimentos fueron realizados 24 horas después de la última sesión de nebulización. El número de células del BAL fue significativamente mayor en los animales del grupo EE, en comparación con los del grupo CC (P0.05) para los linfocitos, neutrófilos, eosinófilos y monocitos; sin embargo, se observaron diferencias significativas (P<0.05) entre los grupos en el número de bastonetes, siendo mayor en los animales del grupo CC en relación al grupo EC. El número de células hematopoyéticas de la médula ósea fue significativamente menor (P<0.05) en los animales del Grupo EE, en comparación con los del grupo de CC. En la corteza prefrontal, hubo diferencias significativas en la relación Ácido Homovanílico/ Dopamina (HVA/DA) (P<0.05), siendo mayor en los animales del grupo EC, en comparación con los del grupo CE. En conclusión, el estrés prenatal produjo modulación de las células del sistema inmune (SI) de los neonatos, evidenciado después de la exposición a un estrés agudo posnatal, por la amplificación de la respuesta alérgica pulmonar. Se sugiere que la mayor susceptibilidad de los animales del grupo EE sea resultado de los cambios inducidos por el estrés prenatal en el eje hipotálamo-pituitaria-adrenal (HPA).

Due to the rapid growth of the fetus it is particularly vulnerable to insults and changes in hormonal milieu. Therefore, is suggested that adverse situations experienced by the pregnant mother can alter the development and health of offspring, mainly due to the permeability of the placental barrier to various hormones and substances. The aim of the present investigation was to study the effects of prenatal stress in the regulation of pulmonary allergic inflammation, employing the murine model of experimental asthma. For this purpose, were used virgin female mice, Swiss lineage, of 50 days old. The models used were foot shock to induce prenatally stress, and "New York subway" stress to induce postnatally stress. Females were divided into 4 groups: CC group: not stressed females; CE group: postnatally stressed females (PND60); EC: females born from stressed mothers (GD15 to GD18); EE Group: females born from stressed mothers (GD15 to GD18) (footshock) and postnatally stressed (PND60). The induction of allergic pulmonary inflammation was done through sensitization of animals with 0,1 mg.Kg-1 sc of ovalbumin (OVA) solution, to further evaluate leukogram, bronchoalveolar lavage (BAL) hematopoietic marrow cellularity and neurochemistry. The experiments were performed 24 hours after the last session of nebulization. The number of BAL cells was significantly higher in EE group animals compared with the CC group (P0.05) for lymphocytes, neutrophils, eosinophils and monocytes; however, there were significant differences (P<0.05) observed in the number of rods cells between groups, being higher in animals the CC group compared to EC group. The number of hematopoietic cells of the bone marrow was significantly lower (P<0.05) in animals of Group EE, compared with CC group. In the prefrontal cortex, there were significant differences in homovanillic acid /dopamine (HVA/DA) (P<0.05) rate, being higher in the EC group, compared to EC group. In conclusion, prenatal stress modulated the immune system (SI) cells of neonates, evidenced after exposure to a post-natal acute stress by amplification of pulmonary allergic response. It is suggested that the increased susceptibility of animals EE group is a result of changes induced by prenatal stress on hypothalamus pituitary-adrenal (HPA) axis.

La teoría de la neuroinmunomodulación en enfermedades neurodegenerativas: nuevas evidencias científicas / Neuroinmmunomodulation in neurodegenerative diseases: new scientific evidence

Microglial cells play a major role in the innate immunity of the central nervous system. Alterations in the normal cross-talks between microglia and brain neuronal cells may lead to serious disturbances and neurodegenerative diseases. We have postulated that neuroinflammatory processes are a critical factor triggering the pathological cascade leading to neuronal degeneration. In our neuroimmunomodulation theory, external or internal damage signals activate microglial cells, producing cytotoxic factors that induce neuronal degeneration. These factors activate protein-kinases, that lead to tau hyperphosphorylation, and its consequent oligomerization. The tau aggregates released into the extracellular medium favor a positive feedback mechanism that determines neurodegeneration. Nowadays, natural components with a string anti-inflammatory activity and that cross the blood brain barrier appears as candidates for prevention and treatment of degenerative brain disorders such as Alzheimers'disease.

Las células microgliales juegan un papel importante en la inmunidad innata del sistema nervioso central. Las alteraciones en la normal diafonía celular, entre microglias y células neuronales cerebrales, pueden conducir a graves disturbios y enfermedades neurodegenerativas. En este contexto, hemos postulado que los procesos neuroinflamatorios son un factor crítico a desencadenar la cascada patológica que conduce a la degeneración neuronal. En nuestra teoría Neuroinmunomoduladora, señales de daños externos o internos activan las células microgliales, favoreciendo la producción de factores citotóxicos que inducen la degeneración neuronal. Estos factores activan la proteína-quinasas, que conducen a la hiperfosforilación de la proteína tau, y su consecuente oligomerización. Estos agregados de tau liberados al medio extracelular, al activar a la célula microglial, provocarían un mecanismo de retroalimentación positiva favoreciendo la neurodegeneración. Hoy en día, compuestos de origen natural con una fuerte actividad anti-inflamatoria, capaces de cruzar la barrera hematoencefálica del cerebro, aparecen como candidatos para la prevención y el tratamiento de trastornos neurodegenerativos tales como la enfermedad de Alzheimer.

Isolation of rat bone marrow-derived mesenchymal stem cells and explore its role in immunomodulation / 天津医药

Objective To explore the immunomodulation property of bone marrow-derived mesenchymal stem cells (BMSCs) from Sprague-Dawley (SD) rats after they are isolated, cultured and identified by surface marker and differentiation potential examination. Methods BMSCs were isolated from femur and tibia of SD rats and passaged by trypsinization. The surface markers of the 3rd passage BMSCs were detected by flow cytometry and the capacity of their adipocyte and cartilage differentiation were examined. In order to explore the immunomodulation property of BMSCs, allogeneic spleen T cells of Wi?star rats were co-cultured with BMSCs through either cell-to-cell contact or transwell, then its effect on the T cell subsets and related mechanism was also examined. Results BMSCs were mainly spindle-shaped in culture. Surface marker detec?tion showed that BMSCs expressed high levels of CD29, CD44 and CD90 but no CD34 nor CD45 at the third generation. Un?der specific condition, BMSCs could differentiate into adipocytes and chondrocytes. The CD8+effector T cells (Teffs) decreas?es effectively and the CD4+CD25+regulatory T cells (Tregs) increased remarkably when BMSCs were co-cultured with allo?geneic spleen T cells for 48 hours. The expressions of IL-10 and TGF-β1 of BMSCs significantly increased after co-culture with T cells, and this effect was more obvious in cell-to-cell contact group. Conclusion The immunomodulation property of BMSCs were presumably function through cell-to-cell contacts and cytokine secretion.

Xenotransplante de células mesenquimais de tecido adiposo humano em modelo de lesão de raízes ventrais da medula espinal de rato / Xenotransplantation of mesenchymal stem cells from human adipose tissue in a rat model of ventral root lesions of the spinal cord

A avulsão de raízes motoras, na interface do sistema nervoso central e periférico, já bem descrito na literatura, promove uma significativa perda sináptica com degeneração de cerca de 80% dos motoneurônios afetados. Não existem estratégias eficazes que propiciem uma reversão ou amenização deste quadro, mas alguns estudos já mostram que o passo fundamental é preservar os motoneurônios afetados. Pesquisas em diferentes áreas com células-tronco (CT) adultas estão sendo realizadas nos últimos anos e apresentam resultados promissores para a medicina regenerativa. Investigações recentes têm apontado para diferentes fontes de CT em tecidos adultos tais como de medula óssea, de sangue de cordão umbilical, tecido muscular, tecido nervoso, líquido amniótico entre outras. De modo geral, estas células apresentam como características principais a capacidade de proliferação e a diferenciação para outros tipos celulares. Entretanto, os principais problemas para o uso clínico das CT adultas são: i) pequena quantidade de células multipotentes, ii) o controle da diferenciação, iii) insuficiência no número de células viáveis e iiii) difícil obtenção. Como alternativa às dificuldades anteriormente citadas, o tecido adiposo tem sido foco de intensos estudos, pois este tecido possui rica fonte de células pluripotentes, além de apresentarem características positivas como fácil acesso ao tecido adiposo subcutâneo, obtenção em quantidade abundante e processo de isolamento celular relativamente simples. Apesar deste tecido apresentar organização complexa, é na fração celular do estroma vascular que se encontra uma rica população de células pluripotentes. Dados de literatura demonstram que as células mesenquimais derivadas de tecido adiposo (AT-MSC - Células mesenquimais de tecido adiposo), mediante incubação com meios de cultura variados, diferenciam-se em adipócitos, osteócitos, mioblastos, hepatócitos, células vasculares entre outras.

It is well described in the literature that avulsion motor at the interface of the central and peripheral nervous system, promotes a significant loss of synaptic degeneration and 80% of motor neurons death. There is no effective strategies that favor a reversal or mitigation of this framework, but some studies have shown that the key step is to preserve motor neurons affected. Researches in different areas with stem cell (CT) adults are being undertaken in recent years and show promising results for regenerative medicine. Recent investigations have pointed to different sources of CT in adult tissues such as bone marrow, umbilical cord blood, brain, muscle tissue, amniotic fluid, among others. Generally, these cells have as main characteristics capacity for proliferation and differentiation to other cell types. However, the main problems for the clinical use of adult SC are: i) small amount of multipotent cells, ii) differentiation control, iii) low number of viable cells and iiii) difficulty to obtain. As an alternative to the difficulties mentioned above, adipose tissue has been the focus of intense study, because this tissue has a rich source of stem cells, in addition to having positive characteristics such as easy access to subcutaneous adipose tissue, obtained in abundant quantities and isolation process relatively simple. Despite the complex tissue organization, the stromal vascular fraction is rich of pluripotent population cells. Literature data show that stromal cells derived from adipose tissue (AT-MSC-adipose tissue mesenchymal stem cells) can differentiate by incubation with various culture media into adipocytes, osteocytes, myoblasts, hepatocytes, vascular cells, among others. The AT-MSC differentiation into neuronal cells is still subject of discussion and criticism in literature, since no established protocol has induced differentiation into function neuronal cells.

Research progress in neuro-immune interactions in Caenorhabditis elegans / 解放军医学杂志

The innate immune response may be activated quickly once the organism is invaded by exotic pathogens. An excessive immune response may result in inflammation and tissue damage, whereas an insufficient immune response may result in infection. Nervous system may regulate the intensity of innate immune responses by releasing neurotransmitters, neuropeptides and hormones. Compared with the complicated neuro-immune system in mammals, it is much simpler in Caenorhabditis elegans. Besides, C. elegans is accessible to genetic, molecular biology and behavioral analyses, so it has been used in studies on neuro-immune interactions. It has been revealed recently in the studies with C. elegans that the neuronal pathways regulating innate immune responses primarily include a transforming growth factor-β (TGF-β) pathway, an insulin/insulin-like growth factor receptor (IGF) pathway and dopaminergic neurotransmission. Since these pathways are evolutionally conservative, so it might be able to provide some new ideas for the research on neuro-immune interactions at molecular levels. The recent progress in this field has been reviewed in present paper.

Mechanism of experimental autoimmune encephalomyelitis in Lewis rats: recent insights from macrophages / 대한해부학회지

Experimental autoimmune encephalomyelitis (EAE) in Lewis rats is an acute monophasic paralytic central nervous system disease, in which most rats spontaneously recover from paralysis. EAE in Lewis rats is induced by encephalitogenic antigens, including myelin basic protein. EAE is mediated by CD4+ Th1 cells, which secrete pro-inflammatory mediators, and spontaneous recovery is mediated by regulatory T cells. Recently, it was established that classically activated macrophages (M1 phenotype) play an important role in the initiation of EAE, while alternatively activated macrophages (M2 phenotype) contribute to spontaneous recovery from rat EAE. This review will summarize the neuroimmunological aspects of active monophasic EAE, which manifests as neuroinflammation followed by neuroimmunomodulation and/or neuroprotection, with a focus on the role of alternatively activated macrophages.
