Nuclear factor-kappa B (NF-κB), which is reported to play an important role in the pathogenesis of depression, also has a central role in the genesis and progression of inflammation. Here, we have targeted the nuclear translocation of NF-κB using 4-methyl-N1-(3-phenyl-propyl)-benzene-1,2-diamine (JSH-23) to elucidate its role in depression. We investigated the antidepressant-like effects of JSH-23 in the chronic mild stress (CMS) mouse model, which is a valid, reasonably reliable, and useful model of depression...

BACKGROUND: Although both chronic lung disease and HIV are inflammatory diseases common in sub-Saharan Africa, the relationship between systemic inflammation and lung function among people living with HIV (PLWH) in sub-Saharan Africa is not well described. METHODS: We measured lung function (using spirometry) and serum high sensitivity C-reactive protein, IL-6, sCD14 and sCD163 in 125 PLWH on stable antiretroviral therapy and 109 age and sex-similar HIV-uninfected controls in rural Uganda...

OBJECTIVE: Antibody responses are often impaired in old age and in HIV+ infection despite virologic control with antiretroviral therapy but innate immunologic determinants are not well understood. DESIGN: Monocytes and natural killer cells were examined for relationships to age, HIV infection and influenza vaccine responses. METHODS: Virologically suppressed HIV+ (n = 139) and HIV- (n = 137) participants classified by age as young (18-39 years), middle-aged (40-59 years) and old (≥60 years) were evaluated preinfluenza and postinfluenza vaccination...

OBJECTIVE: During effective antiretroviral therapy (ART), low-level plasma viremias (LLV) (HIV RNA >30-1000 copies/ml) can be detected intermittently. We hypothesized that systemic inflammation is associated with LLV either as the cause or result of the production of virions from clonally expanded cells. METHODS: Prospective cohort study of HIV-infected ART-naïve Peruvians enrolled prior to ART and followed for 2 years. Plasma HIV RNA and peripheral blood mononuclear cell (PBMC) HIV DNA concentrations were quantified pre-ART from individuals whose plasma HIV RNA was ART-suppressed...

In this study, we demonstrate, for the first time, that Saccharomyces cerevisiae-based probiotic shows an inhibitory effect on Gardnerella vaginalis infection. This effect is likely due to several actions: direct interference with adherence to vaginal tissues, inhibition of sialidase activity, reduction of vaginal epithelial exfoliation. Gardnerella vaginalis does not induce vaginal inflammation and no inflammatory cytokines were, indeed, produced, by the mouse vagina, neither by Gardnerella vaginalis and by the probiotic...

Although psoriasis is predominantly a chronic inflammatory skin disorder, it has been known to be associated with cardiovascular disease. Patients with psoriasis, particularly with moderate to severe forms, present an increased rate of cardiovascular mortality, myocardial infarction and stroke. However the pathophysiology of the relationship between psoriasis and cardiovascular risk and comorbidities has not yet completely known. Chronic inflammation may be considered a solid link between psoriasis and related cardiovascular events...

BACKGROUND: Conventional photodynamic therapy (PDT) is associated with side effects, primarily related to the waiting time between pre-treatment with application of photosensitizer and illumination. Pain during illumination is a major issue for the patients and options for effective pain relief are limited. Post-treatment inflammation can often be severe and cause inconvenient down-time for the patients and their employers. METHODS: To avoid the problems of pain and patients crowding in the clinic we eliminated red light treatment of high PpIX concentration and introduced illumination in daylight which may be performed at home...

Hematopoietic stem and progenitor cells reside within the bone marrow (BM) microenvironment. By a well-balanced interplay between self-renewal and differentiation, they ensure a lifelong supply of mature blood cells. Physiologically, multiple different cell types contribute to the regulation of stem and progenitor cells in the BM microenvironment by cell-extrinsic and cell-intrinsic mechanisms. During the last decades, mesenchymal stromal cells (MSCs) have been identified as one of the main cellular components of the BM microenvironment holding an indispensable role for normal hematopoiesis...

Pediatric uveitis differs from adult-onset uveitis and is a topic of special interest because of its diagnostic and therapeutic challenges. Children with uveitis are often asymptomatic and the uveitis is often chronic, persistent, recurrent, and resistant to conventional treatment. Anterior uveitis is the most common type of uveitis in children; the prevalence of intermediate, posterior, and panuveitis varies geographically and among ethnic groups. Regarding etiology, most cases of pediatric uveitis are idiopathic but can be due to systemic inflammatory disorders, infections, or a manifestation of masquerade syndrome...

REVIEW
Diego Gómez-Moreno, José María Adrover, Andrés Hidalgo
Vascular inflammation underlies most forms of cardiovascular disease, which remains a prevalent cause of death among the global population. Advances in the biology of neutrophils, as well as insights into their dynamics in tissues, have revealed that these cells are prominent drivers of vascular inflammation though derailed activation within blood vessels. The development of powerful imaging techniques, as well as identification of cells and molecules that regulate their activation within vessels, including platelets and catecholamines, have been instrumental to better understand the mechanisms through which neutrophils protect or damage the organism...

Background: Recent animal studies have shown that mitochondrial dysfunction initiates and accelerates renal injury in sepsis, but its role in sepsis remains unknown. Mitochondrial stress or dying cells can lead to fragmentation of the mitochondrial genome, which is considered a surrogate marker of mitochondrial dysfunction. Therefore, we evaluated the efficiency of urinary mitochondrial DNA (UmtDNA) as a marker of renal dysfunction during sepsis-induced acute kidney injury (AKI). Methods: We isolated DNA from plasma and urine of patients...

Background: In rheumatoid arthritis, articular inflammation is a hallmark of disease, while the involvement of extra-articular tissues is less well defined. Here, we examined the feasibility of PET imaging with the macrophage tracer [18 F]fluoro-PEG-folate, targeting folate receptor β (FR β ), to monitor systemic inflammatory disease in liver and spleen of arthritic rats before and after methotrexate (MTX) treatment. Methods: [18 F]Fluoro-PEG-folate PET scans (60 min) were acquired in saline- and MTX-treated (1 mg/kg, 4x) arthritic rats, followed by tissue resection and radiotracer distribution analysis...

Ultrasound myocardial cavitation-enabled treatment was applied to the SS-16BN rat model of hypertrophic cardiomyopathy for proof of the principle underlying myocardial reduction therapy. A focused ultrasound transducer was targeted using 10-MHz imaging (10 S, GE Vivid 7) to the left ventricular wall of anesthetized rats in a warmed water bath. Pulse bursts of 4-MPa peak rarefactional pressure amplitude were intermittently triggered 1:8 heartbeats during a 10-min infusion of a microbubble suspension. Methylprednisolone was given to reduce initial inflammation, and Losartan was given to reduce fibrosis in the healing tissue...

Spondyloarthritis (SpA) encompasses a heterogeneous group of diseases sharing genetic, immunological, clinical and imaging features. Axial spondyloarthritis (axSpA) refers to a subgroup characterised predominately by inflammation of the axial skeleton with subsequent symptoms of chronic (often inflammatory) back pain and sacroiliitis. There is a strong association with the major histocompatibility complex (MHC) class I allele human leukocyte antigen (HLA) B27. In the last decade, there has been significant progress in earlier detection of the disease and the molecular mechanisms involved in its pathogenesis...

BACKGROUND: There is evidence for inflammation, autophagy, and apoptosis in the ischemic heart. Autophagy is a physiologic process for tissue survival. Apoptosis, on the other hand, is a mechanism that serves to clear the debris in the setting of tissue injury. The balance between autophagy and apoptosis may be important in cell survival and cardiac function. METHODS AND RESULTS: We examined the interplay of inflammation and myocyte autophagy and apoptosis during the ischemic process...

Epidermal growth factor receptor (EGFR) is a known target in cancer therapy and targeting the receptor has proven to be extremely successful in treating cancers that are dependent on EGFR signaling. To that effect, targeted therapies to EGFR such as Cetuximab, Panitumumab-monoclonal antibodies and Gefitinib, Erlotinib-tyrosine kinase inhibitors have had success in therapeutic scenarios. However, the development of resistance to these drugs makes it necessary to combine anti- EGFR therapies with other inhibitors, so that resistance can be overcome by the targeting of alternate signaling pathways...
