Hemophagocytic Lymphohistiocytosis (HLH) is a life-threatening disorder of immune dysregulation characterized by fever, hepatosplenomegaly, cytopenias, CNS disease, increased inflammatory markers and hemophagocytosis. Currently, allogeneic hematopoietic stem cell transplantation is the only curative approach for patients with HLH with reported survival ranging from 50-70% with myeloablative conditioning (MAC) regimens. However, donor availability and transplant related mortality associated with conventional MAC are major barriers to success...

This study examined the impact of corticotropin-releasing hormone type 1 receptor (CRHR1) blockade using Antalarmin (ANT) on the expression of markers of neuroplasticity and inflammation, as well as neuroprotection and behavioral recovery following global cerebral ischemia. Male Wistar rats (N=50) were treated with ANT (2μg/2μl; icv) or a vehicle solution prior to a sham or four vessel (4VO) occlusion. Seven days post ischemia, anxiety was assessed in the Elevated Plus Maze and Open Field tests, and fear and spatial learning in a Y-Maze Passive Avoidance Task and the Barnes Maze...

Vitiligo, the most common depigmenting disorder, is caused by immune destruction of melanocytes by cytotoxic CD8(+) T cells. One weakness in vitiligo management is the lack of an assessment method for active depigmentation. Beginning with reports about increased S100B levels in different inflammatory and tissue damage processes, Speeckaert et al. explored correlations between the S100B dynamics and vitiligo activity, identifying high circulating S100B levels in patients with active depigmentation which were strongly correlated with the extent of affected skin surface...

Inflammation is an important mediator of most forms of acute kidney injury (AKI). Although neutrophils are prominent components of the inflammatory cascade, the precise role of neutrophils in AKI and the mechanisms by which they contribute to AKI remain controversial. In this issue, Deng et al. identify an important cross talk between renal epithelial cells and neutrophils involving the production and action of leukotriene B4 in mediating cisplatin AKI. We discuss the possible explanations for the discrepant findings that have been reported for neutrophils in cisplatin AKI...

BACKGROUND: Host factors determining the clinical presentation of tick-borne encephalitis (TBE) are not fully elucidated. The peripheral inflammatory response to TBE virus is hypothesized to facilitate its entry into central nervous system by disrupting the blood-brain barrier with the involvement of a signaling route including Toll-like receptor 3 (TLR3) and pro-inflammatory cytokines macrophage migration inhibitory factor (MIF), tumor necrosis factor-α (TNFα), and interleukin-1 beta (IL-1β)...

Context • Balneotherapy is one of the most commonly used nonpharmacological interventions for osteoarthritis (OA), but its mechanism of action in relieving pain and stiffness and in improving physical function is not well understood. Studies have found that therapy provokes a series of neuroendocrinal reactions with anti-inflammatory and analgesic effects. Sphingosine-1-phosphate (S1P), a bioactive lipid, has been implicated as an important mediator in the maintenance of physiological processes (eg, vascular barrier integrity) and in pathophysiologic processes such as inflammatory conditions...

BACKGROUND: As lipids are known to regulate macrophage functions it is reasonable to suppose that a sebocyte - macrophage axis mediated by sebum lipids may exist. OBJECTIVE: To investigate if sebocytes could contribute to the differentiation, polarization and function of macrophages with their secreted lipids. METHODS: Oil-red-O lipid staining and Raman spectroscopy were used to assess the dermal lipid content and penetration. Immunohistochemistry was used to analyse the macrophage subsets...

Hepatocellular adenomas (HCA) are rare benign tumors divided into three main subgroups defined by patho-molecular features, HNF1A (H-HCA), mutated β-catenin (b-HCA) and inflammatory (IHCA). In the case of unclassified HCA (UHCA), which are currently identified by default, a high risk of bleeding remains a clinical issue. The objective of this study was to explore UHCA proteome with the aim to identify specific biomarkers. Following dissection of the tumoral (T) and non-tumoral (NT) tissue on formalin-fixed paraffin-embedded (FFPE) from HCA tissue sections using laser capture methodology, we performed mass spectrometry analysis to compare T and NT protein expression levels in HCA, H-HCA, IHCA, b-HCA, UHCA and focal nodular hyperplasia...

G-CSF is a growth factor that has known neuroprotective effects in a variety of experimental brain injury models. As both antigen-presenting microglia and reactive T cells are key components in the development and progression of EAE, the aim of this study is to investigate the neuroprotective effects of recombinant human G-CSF, as administered in microglia-mediated reactive T cell assay in vitro. Our results indicate that G-CSF treatment has no apparent effect for the resting un-activated microglia. G-CSF pre-protection of microglia increased protective cytokine IL-4 production and effectively inhibited the productions of NO and other inflammatory mediators (IFN-γ, TNF-α, IL-1β, IL-17, and chemokine MCP-1) after LPS stimulation...

Severe burns induce a prolonged inflammatory response in subcutaneous adipose tissue that modulates signaling in adipose-derived stem cells (ASCs), which hold potential for healing burn wounds or generating skin substitutes. Using a 60% rat scald burn model, we conducted a series of experiments to determine which cells isolated from the adipose tissue produced inflammatory mediators and how these changes affect ASC fate and function. The stromal vascular fraction (SVF), adipocytes, and ASCs were isolated from adipose tissue at varying times up to 4 weeks postburn and from non-injured controls...

Diets high in advanced glycation end products (AGEs) are thought to be detrimental to cardiovascular health. However, there remains uncertainty about the beneficial effect of a low AGE diet on cardiovascular risk factors and inflammatory markers in overweight individuals. We thus performed a randomised, double blind, crossover trial to determine whether consumption of low AGE diets reduce inflammation and cardiovascular risks in overweight and obese otherwise healthy adults. All participants (n = 20) consumed low and high AGE diets alternately for two weeks and separated by a four week washout period...

BACKGROUND & AIMS: Non-alcoholic fatty liver disease (NAFLD) is the most common form of liver disease. Activation of hedgehog (Hh) signaling has been implicated in the progression of NAFLD and proposed as a therapeutic target; however, the effects of Hh signaling inhibition have not been studied in humans with germline mutations affecting this pathway. METHODS: Patients with holoprosencephaly (HPE), a disorder associated with germline mutations disrupting Sonic hedgehog (SHH) signaling, were clinically evaluated for NAFLD...

Inflammation has been recently acknowledged as a key participant in the physiopathology of oncogenesis and tumor progression. The inflammatory cytokine IL-1β has been reported to induce the expression of markers associated with malignancy in breast cancerous cells through Epithelial-Mesenchymal Transition (EMT). Aggressive breast cancer tumors classified as Triple Negative do not respond to hormonal treatment because they lack three crucial receptors, one of which is the estrogen receptor alpha (ERα). Expression of ERα is then considered a good prognostic marker for tamoxifen treatment of this type of cancer, as the binding of this drug to the receptor blocks the transcriptional activity of the latter...

BACKGROUND: Dendritic cells (DCs) are specialized first-line sensors of foreign materials invading the organism. These sentinel cells rely on pattern recognition receptors such as Nod-like or Toll-like receptors (TLRs) to launch immune reactions against pathogens, but also to mediate tolerance to self-antigens and, in the intestinal milieu, to nutrients and commensals. Since inappropriate DC activation contributes to inflammatory diseases and immunopathologies, a key question in the evaluation of orally ingested nanomaterials is whether their contact with DCs in the intestinal mucosa disrupts this delicate homeostatic balance between pathogen defense and tolerance...

The impact of Pseudomonas aeruginosa biofilm infections in chronic wounds and clinical implication for healing is receiving increased attention. However, the pathophysiology of host/pathogen interplay is not fully understood. By further revealing the mechanisms, necessary new treatment strategies may be identified. Since the background for chronic wounds is diverse, representative animal models are important. We assessed host response and spontaneous wound closure in the relatively resistant C3H/HeN and the susceptible BALB/c mouse strain...
