Diabetic encephalopathy (DE) is one of the most common diabetic complications in diabetes mellitus and is characterized by cognitive impairment and neuroinflammation. It has been reported that hyperglycemia can induce hippocampal and cortical neuronal damage, which can result in severe spatial learning and memory impairment. Pinocembrin (Pino) has been widely used in the therapy of cancer and other diseases due to its anti-inflammatory, anti-allergic, anti-oxidant, anti-carcinogenic, and anti-viral activities...

Over activation of glial cell derived innate immune factors induces neuro-inflammation that results in neurodegenerative disease, like working memory impairment. In this study, we have investigated the role of andrographolide, a major constituent of Andrographis paniculata plant, in reduction of reactive glial cell derived working memory impairment. Real time PCR, Western bloting, flow cytometric and immunofluorescence studies demonstrated that andrographolide inhibited lipopolysaccharide (LPS)-induced overexpression of HMGB1, TLR4, NFκB, COX-2, iNOS, and release of inflammatory mediators in primary mix glial culture, adult mice prefrontal cortex and hippocampus region...

Multiple sclerosis (MS) is a chronic autoimmune demyelinating disease of the central nervous system. Currently, there is no drug available to cure this kind of disease. Diosgenin is a plant-derived steroid saponin. A previous study in our lab revealed that diosgenin can promote oligodendrocyte progenitor cell differentiation and accelerate remyelination. In the present study, we found that diosgenin dose-dependently alleviated the progression of experimental autoimmune encephalomyelitis with reduced central nervous system inflammation and demyelination...

Glycolysis and mitochondrial respiration are essential for oligodendrocyte metabolism in both the developing and adult CNS. Based on recent reports on the effects of the proinflammatory cytokine IFN-γ on metabolism and on oligodendrocytes, we addressed whether IFN-γ may affect oligodendrocyte bioenergetics in ways relevant to CNS disease. Oligodendrocytes of mice treated with IFN-γ showed significant reductions in aerobic glycolysis and mitochondrial respiration. As expected, IFN-γ treatment led to the induction of STAT1 in oligodendrocytes indicating active signaling into these cells...

Microglia are the primary resident immune cells of the brain parenchyma and transform into the amoeboid form in the "activated state" under pathological conditions from the ramified form in the "resting state" under physiologically healthy conditions. In the present study, we found that microglia in the circumventricular organs (CVOs) of adult mice displayed the amoeboid form with fewer branched cellular processes even under normal conditions; however, those in other brain regions showed the ramified form, which is characterized by well-branched and dendritic cellular processes...

BACKGROUND: Cancer-related cognitive impairment (CRCI) is often related to chemotherapy. Increased chronic inflammation is believed to play a key role in the development of CRCI related to chemotherapy but studies assessing this hypothesis specifically in patients receiving chemotherapy are rare. METHODS: We assessed several cognitive domains using the Cambridge Neuropsychological Test Automated Battery (CANTAB) in twenty-two breast cancer patients currently receiving chemotherapy...

Benzodiazepines are psychoactive drugs and some of them also affect immune cells. We here characterized the inflammatory and infiltrating immune cells in the central nervous system (CNS) during the acute phase of experimental autoimmune encephalomyelitis (EAE) in animals treated with Diazepam. Also, we evaluated the expression of Translocator Protein (18kDa) (TSPO), which is a biomarker of neuroinflammatory diseases. The results indicate that Diazepam exerts protective effects on EAE development, decreasing the incidence of the disease and reducing the number of inflammatory cells in CNS, with a concomitant decrease of TSPO levels in brain tissue and CNS inflammatory CD11b(+) cells...

Recent studies have implicated an important role for coagulation factors in neuroinflammatory disorders like multiple sclerosis (MS). Here, we investigate the role of factor X (FX) in neuroinflammation by using rivaroxaban the selective inhibitor of activated FX (FXa) in experimental autoimmune encephalomyelitis (EAE, an animal model of MS). Rivaroxaban-treated rats were less susceptible to EAE compared to the untreated control group. This finding was accompanied by reduced T-cell infiltration and microglia activation...

Increased plasma pro-inflammatory and decreased anti-inflammatory cytokines have been implicated in physiological and behavioural aspects of mood- and pain-related disorders, including migraine. In this case-control study, we assessed mood scores, cardiorespiratory fitness (VO2Peak), and plasma concentrations of TNF-α, IL-1β, IL-6, IL-8, IL-10, and IL-12p70 interictally in women with episodic migraine with/without aura (ICHD-II), taking no preventive medicine, and in healthy women recruited from São Paulo Hospital and local community, respectively...

Activated microglial cells produce the pro-inflammatory mediators such as nitric oxide (NO) and cytokines. The excessive release of these mediators can lead to neurodegenerative diseases, such as Alzheimer's disease (AD) and Parkinson's disease (PD). Inhibition of the release of these pro-inflammatory molecules may prevent or halt the progression of these diseases. Plumbagin (PL), a naphthoquinone compound in the roots of the traditional medicinal plant Plumbago zeylanica L., showed anti-inflammatory effects on macrophages...

Inflammatory-like changes in the white matter (WM) are commonly observed in conditions of axonal degeneration by different etiologies. This study is a systematic comparison of the principal features of the inflammatory-like changes in the WM in different pathological conditions characterized by axonal damage/degeneration, focusing in particular on Multiple Sclerosis (MS) normal-appearing white matter (NAWM) compared to non immune-mediated disorders. The study was performed on sections of NAWM from 15 MS cases, 11 cases of non immune-mediated disorders with wallerian axonal degeneration (stroke, trauma, amyotrophic lateral sclerosis), 3 cases of viral encephalitis, 6 control cases...

OBJECTIVE: Pediatric Acute Neuropsychiatric Syndrome (PANS) and pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS) are conditions marked by sudden onset of obsessive-compulsive disorder (OCD), tics, or avoidant/restrictive food intake in combination with multiple psychiatric symptoms. A diagnosis of PANS or PANDAS may be supported by the Cunningham Panel, a commercially available set of immunologic assays currently in clinical use. However, the relationship between Cunningham Panel results and patient symptoms remains unclear...

Myasthenia gravis (MG) is caused by autoantibodies, the majority of which target the muscle acetylcholine receptor (AChR). Plasmapheresis and IgG-immunoadsorption are useful therapy options, but are highly non-specific. Antigen-specific immunoadsorption would remove only the pathogenic autoantibodies, reducing the possibility of side effects while maximizing the benefit. We have extensively characterized such adsorbents, but in vivo studies are missing. We used rats with experimental autoimmune MG to perform antigen-specific immunoadsorptions over three weeks, regularly monitoring symptoms and autoantibody titers...

We aimed to investigate the glial cells activation as a potential mechanism involved in the sleep deprivation (SD) induced cognitive impairment through changes in inflammatory cytokines. We analyzed the spatial memory, inflammatory cytokine levels, and gliosis during SD. SD induced spatial memory impairment, imbalance of inflammatory (increased pro- and decreased anti-) cytokines in both hippocampus and plasma in association with glial cells activation in the hippocampus of sleep-deprived rats were observed...

We aimed to evaluate the usefulness of sepsis biomarkers to predict stroke-associated infections. Soluble triggering receptor expressed on myeloid cells-1 (sTREM-1), mid-regional pro-adrenomedullin (MR-proADM), presepsin (sCD14), and soluble urokinase-type plasminogen activator receptor (suPAR), were explored in 125 blood samples collected at different time-points. At baseline, MR-proADM was an independent predictor of infection [>0.94pg/mL, OR=3.63 (1.16-11.33), p=0.026], as well as suPAR at 24h [>2185...

We describe an extremely severe case of therapy refractory NMDA receptor encephalitis (NMDAe) in a 26-year-old woman. After rituximab, bilateral oophorectomy, repeated cycles of high dose methylprednisolone and plasma exchange, she received repeated cyclophosphamide, tocilizumab (interleukin-6 inhibitor) and finally bortezomib (plasma cell depleting drug) leading to remission after 204days in intensive care. Two years after disease onset her cognitive functions are still affected, but slowly improving and the cerebral atrophy has been partly reversed...
