Microglial angiotensin type 2 receptors mediate sex-specific expression of inflammatory cytokines independently of circulating estrogen

There are sex differences in microglia, which can maintain sex-related gene expression and functional differences in the absence of circulating sex steroids. The angiotensin type 2 (AT2) receptors mediate anti-inflammatory actions in different tissues, including brain. In mice, we performed RT-PCR analysis of microglia isolated from adult brains and RNA scope in situ hybridization from males, fema

Prostaglandin EP2 Receptors Mediate Mesenchymal Stromal Cell-Neuroprotective Effects on Dopaminergic Neurons

Mesenchymal stromal cells (MSCs) have been shown to have useful properties for cell therapy and have been proposed for treatment of neurodegenerative diseases, including Parkinson’s disease. However, the mechanisms involved in recovering dopaminergic neurons are not clear. The present study aims to evaluate the pathways and molecules involved in the neuroprotective effect of MSCs. We analyzed the

School principals' proposals for preventive actions to improve mental health

BACKGROUND: School principals face a demanding work situation that puts them at risk for stress-related poor mental health. Ideally, preventive actions should be based on knowledge about the underlying notions that motivate action. However, knowledge about prevention areas and suitable initiatives for school principals is scarce or lacking, leaving key stakeholders without the overview necessary f

Nrf2 activation and downstream effects : Focus on parkinson’s disease and brain angiotensin

Reactive oxygen species (ROS) are signalling molecules used to regulate cellular metabolism and homeostasis. However, excessive ROS production causes oxidative stress, one of the main mechanisms associated with the origin and progression of neurodegenerative disorders such as Parkinson’s disease. NRF2 (Nuclear Factor-Erythroid 2 Like 2) is a transcription factor that or-chestrates the cellular res

Dopamine regulates adult neurogenesis in the ventricular-subventricular zone via dopamine D3 angiotensin type 2 receptor interactions

Adult neurogenesis is a dynamic and highly regulated process, and different studies suggest that dopamine modulates ventricular-subventricular zone (V-SVZ) neurogenesis. However, the specific role of dopamine and the mechanisms/factors underlying its effects on physiological and pathological conditions such as Parkinson's disease (PD) are not fully understood. Recent studies have described counter

Kind of Folk VOL 5 - Poland : concert with Groupa

Groupa started the new project 'Kind of Folk VOL 5 - Poland'. A collaboration with polish musicians: Grzech Piotrowski - sax, Marta Matuszna - vocalsThis day there was a concert at the Skansen museum nearby Olsztyn.

Dose-dependent effect of mesenchymal stromal cells co-grafted with dopaminergic neurons in a Parkinson's disease rat model

A major limiting factor for cell therapy in Parkinson's disease is the poor survival and reinnervation capacity of grafted dopaminergic neurons, independently of the cell source. Mesenchymal stromal cells (MSCs) have high capability to regulate the local environment through the release of trophic, antiapoptotic and immunomodulatory factors. In this work, we investigated whether co-grafting of MSCs

Posttraumatic stress disorder and its cross-generational familial relationship with drug use disorder and alcohol use disorder : an extended Swedish adoption study

Objective: Information on how parental risk for posttraumatic stress disorder (PTSD) relates to their children’s risk for drug use disorder (DUD) and alcohol use disorder (AUD) is limited. This study is the first to utilize an extended adoption design which can address questions about the degree of, and sources of, cross-generational and cross-disorder transmission of PTSD and substance use disord

Angiotensin II induces oxidative stress and upregulates neuroprotective signaling from the NRF2 and KLF9 pathway in dopaminergic cells

Nuclear factor-E2-related factor 2 (NRF2) is a transcription factor that activates the antioxidant cellular defense in response to oxidative stress, leading to neuroprotective effects in Parkinson's disease (PD) models. We have previously shown that Angiotensin II (AngII) induces an increase in reactive oxygen species (ROS) via AngII receptor type 1 and NADPH oxidase (NOX), which may activate the

Data on the effect of Angiotensin II and 6-hydroxydopamine on reactive oxygen species production, antioxidant gene expression and viability of different neuronal cell lines

This article describes the effect of the oxidative stress inducers Angiotensin II and 6-hydroxydopamine (6-OHDA) on different cell lines. The levels of expression Angiotensin type 1 and type 2 receptors in different dopaminergic cell lines are shown. The data indicate that treatment with Angiotensin II and 6-OHDA increases the production of reactive oxygen species (ROS) and decreases cell viabilit

Nadph-oxidase, rho-kinase and autophagy mediate the (Pro)renin-induced pro-inflammatory microglial response and enhancement of dopaminergic neuron death

Dysregulation of the tissue renin–angiotensin system (RAS) is involved in tissue oxidative and inflammatory responses. Among RAS components, renin, its precursor (pro)renin and its specific receptor (PRR) have been less investigated, particularly in the brain. We previously showed the presence of PRR in neurons and glial cells in the nigrostriatal system of rodents and primates, including humans.

Angiotensin type 2 receptors : Role in aging and neuroinflammation in the substantia nigra

Overactivity of the angiotensin-type-1 receptor (AT1)/NADPH-oxidase axis enhances aging processes, neuroinflammation and neurodegeneration. The role of AT2 receptors in the above-mentioned AT1-related effects in the aged brain, particularly substantia nigra, was investigated in this study. In the nigra, we observed a progressive decrease in AT2 mRNA expression with aging, and AT2 deletion led to c

Interaction between angiotensin type 1, type 2, and mas receptors to regulate adult neurogenesis in the brain ventricular–subventricular zone

The renin–angiotensin system (RAS), and particularly its angiotensin type-2 receptors (AT2), have been classically involved in processes of cell proliferation and maturation during development. However, the potential role of RAS in adult neurogenesis in the ventricular-subventricular zone (V-SVZ) and its aging-related alterations have not been investigated. In the present study, we analyzed the ro

Botaniska vandringar på Kullen. Om fältbotanikern Bengt Lidforss

The Swedish botanist, Darwinist, socialist, and atheist Bengt Lidforss (1868–1913) passed away one hundred years ago, on September 23, 1913. His research was mainly focused on plant physiology, and the problem of speciation within the genus Rubus (blackberries) in particular came to follow him as a constant mystery. Besides his work as a teacher, researcher, and finally professor of botany at Lund
