Partial MHC class II constructs as novel immunomodulatory therapy for stroke
Publication date: Available online 31 October 2016 Source:Neurochemistry International Author(s): Gil Benedek, Arthur A. Vandenbark, Nabil J. Alkayed, Halina Offner The worldwide prevalence of stroke continues to rise despite recent successes in treating acute ischemic stroke. With limited patient eligibility and associated risk of tPA and mechanical thrombectomy, new preventive and therapeutic modalities are needed to stave the rising wave of stroke. Inflammation plays a key role in brain damage after cerebral ischemia, and novel therapies that target pro-inflammatory cells have demonstrated promise for treatment for str...

Regulatory T lymphocytes as a therapy for ischemic stroke
AbstractUnrestrained excessive inflammatory responses exacerbate ischemic brain injury and impede post-stroke brain recovery. CD4+CD25+Foxp3+ regulatory T (Treg) cells play important immunosuppressive roles to curtail inflammatory responses and regain immune homeostasis after stroke. Accumulating evidence confirms that Treg cells are neuroprotective at the acute stage after stroke and promote brain repair at the chronic phases. The beneficial effects of Treg cells are mediated by diverse mechanisms involving cell –cell interactions and soluble factor release. Multiple types of cells, including both immune cells and non-i...

Effects of Neurotrophic Factors in Glial Cells in the Central Nervous System: Expression and Properties in Neurodegeneration and Injury
Conclusion and Future Aspects This review summarizes available NTF expression data, compiles existing evidence on the effects of glial NTF signaling in healthy conditions and in disease models (Figure 1), and highlights the importance of this topic for future studies. The relationship between NTFs and glia is crucial for both the developing and adult brain. While some of these factors, such as NT-3 and CNTF, have highly potent effects on gliogenesis, others like BDNF and GDNF, are important for glia-mediated synapse formation. Neurotrophic factors play significant roles during neurodegenerative disorders. In many cases, ...

Phagocytosis in the Brain: Homeostasis and Disease
Conclusions and Perspectives In this review we have summarized the critical role phagocytosis plays in both CNS homeostasis and disease. While much progress has been made in recent years, many unanswered questions remain. How phagocytosis in the CNS is influenced by numerous factors, such as microenvironment or phagocytic target, have yet to be fully resolved. Additionally, the utilization of novel technologies, including in vivo imaging techniques (217), iPSC-derived microglia (213) and high-throughput screens (66), will likely contribute to further identification of phagocytic pathways and consequences of phagocytosis w...

Subclinical Atherosclerosis in Primary Sj ögren's Syndrome: Does Inflammation Matter?
Conclusions The markers of endothelial activation and damage and of chronic inflammation investigated until now failed to result predictors of subclinical atherosclerosis or to be associated with increased risk of CV events in SS patients. This may suggest that other mechanisms are implicated with increased prevalence of subclinical atherosclerosis in SS or that these biomarkers exert a different mechanism in the pathogenesis of endothelial damage and in the induction of atherosclerosis. Surely, the relationship between the disease itself and inflammatory and immune dysfunction factors is quite complex and still to be cla...

Billions With Nutrition Deficiency!?
Almost no one gets enough selenium. Officially, at least a billion — with a B — people have a selenium deficiency.1 But I suspect the numbers are much higher than that. You can’t get enough selenium from food alone anymore. That’s true even if you eat a healthy, varied diet. And you can thank Big Agra for that. With their harsh pesticides, synthetic fertilizers, and single-crop strategy, these massive farms have stripped the nutrients out of the soil. No nutrients in the soil mean no nutrients in the food. All of this makes it difficult — if not impossible — to get even some of the daily selenium you need to ...

One special question to start with: Can HIF/NFkB be a target in inflammation?
Abstract Hypoxia and Inflammation are strictly interconnected with important consequences at clinical and therapeutic level. While cell and tissue damage due to acute hypoxia mostly leads to cell necrosis, in chronic hypoxia, cells that are located closer to vessels are able to survive adapting their phenotype through the expression of a number of genes, including proinflammatory receptors for alarmins. These receptors are activated by alarmins released by necrotic cells and generate signals for master transcription factors such as NFkB, AP1, etc. which control hundreds of genes for innate immunity and damage repa...

Immunotherapy strategies for spinal cord injury.
Abstract Regeneration in the central nervous system (CNS) of adult mammalian after traumatic injury is limited, which often causes permanent functional motor and sensory loss. After spinal cord injury (SCI), the lack of regeneration is mainly attributed to the presence of a hostile microenvironment, glial scarring, and cavitation. Besides, inflammation has also been proved to play a crucial role in secondary degeneration following SCI. The more prominent treatment strategies in experimental models focus mainly on drugs and cell therapies, however, only a few strategies applied in clinical studies and therapies sti...

Connecting Metainflammation and Neuroinflammation Through the PTN-MK-RPTP β/ζ Axis: Relevance in Therapeutic Development
Conclusion The expression of the components of the PTN-MK-RPTPβ/ζ axis in immune cells and in inflammatory diseases suggests important roles for this axis in inflammation. Pleiotrophin has been recently identified as a limiting factor of metainflammation, a chronic pathological state that contributes to neuroinflammation and neurodegeneration. Pleiotrophin also seems to potentiate acute neuroinflammation independently of the inflammatory stimulus while MK seems to play different -even opposite- roles in acute neuroinflammation depending on the stimulus. Which are the functions of MK and PTN in chronic neuroi...

Sex Difference of Radiation Response in Occupational and Accidental Exposure
Conclusion and Outlook This review summarizes the data from major human studies on the health risks of radiation exposure and shows that sex can potentially influence the prolonged response to radiation exposure (Figure 1 and Tables 1, 2). These data suggest that long-term radiosensitivity in females is higher than that in males who receive a comparable dose of radiation. Our analysis of the literature agrees with the conclusions of the recent report on the Biological effects of ionizing radiation (BEIR VII) published in 2006 by the National Academy of Sciences (NAS), United States (National Research Council, 2006). The B...

Regulatory T Cells: Pathophysiological Roles and Clinical Applications.
Abstract Inflammation and immune responses after tissue injury play pivotal roles in the resolution of inflammation, tissue recovery, fibrosis, and remodeling. Regulatory T cells (Tregs) are responsible for immune tolerance and are usually activated in secondary lymphatic tissues. Activated Tregs subsequently regulate effector T cell and dendritic cell activation. For clinical applications such as the suppression of both autoimmune diseases and the rejection of transplanted organs, methods to generate stabilized antigen-specific Tregs are required. For this purpose, transcriptional and epigenetic regulation of Fox...
