A 2-year-old male Jindo dog was presented to a local veterinary clinic for anorexia, lethargy, edema around neck, and vomiting. Based on the clinical history, physical examination, hematology, blood chemistry, serology, and PCR, the dog was diagnosed with canine granulocytic anaplasmosis (CGA). PCR and phylogenetic analyses targeting the 16S rRNA, groEL, and msp2 genes of Anaplasma phagocytophilum revealed that the A. phagocytophilum identified in this study subgrouped into alanine and USA groups according to the groEL and msp2 gene sequences, respectively...

OBJECTIVES: Despite the therapeutic value of current rheumatoid arthritis (RA) treatments, agents with alternative modes of action are required. Mavrilimumab, a fully human monoclonal antibody targeting the granulocyte-macrophage colony-stimulating factor receptor-α, was evaluated in patients with moderate-to-severe RA. METHODS: In a phase IIb study (NCT01706926), patients with inadequate response to ≥1 synthetic disease-modifying antirheumatic drug(s), Disease Activity Score 28 (DAS28)-C reactive protein (CRP)/erythrocyte sedimentation rate ≥3...

BACKGROUND: Pulmonary alveolar proteinosis (PAP) is a rare lung disease characterized by surfactant accumulation, and is caused by disruption of granulocyte/macrophage colony-stimulating factor (GM-CSF) signaling. Abnormalities in CSF2 receptor alpha (CSF2RA) were reported to cause pediatric hereditary PAP. We report here the first case of CSF2RA-mutated, elderly-onset hereditary (h) PAP. CASE PRESENTATION: The patient developed dyspnea on exertion, and was diagnosed with PAP at the age of 77 years, based on findings from chest computed tomography scan and bronchoalveolar lavage...

In previous studies, it has been shown that the granulocyte macrophage-colony stimulating factor (GM-CSF) or interleukin-2 (IL-2) surface modified MB49 bladder cancer stem cells (MCSCs) vaccine could induce a specific antitumor immunity and against bladder cancer in mice model respectively. However, whether combined administration of GM-CSF and IL-2 could produce specific immune responses to cancer stem cells (CSCs) was uncertain. MCSCs were established and characterized. GM-CSF and IL-2 MCSCs vaccines were prepared and bioactivity was evaluated...

BACKGROUND: Granulocyte and monocyte apheresis (GMA) has shown therapeutic efficacy in active ulcerative colitis (UC). We thought that in patients with pouchitis after proctocolectomy for UC, GMA might produce immunological effects in the intestinal mucosa, and improve clinical symptoms. This prospective study was to evaluate the efficacy of GMA for antibiotic-refractory pouchitis after proctocolectomy for UC. METHODS: A total of 13 patients with pouchitis disease activity index (PDAI) > 7 unresponsive to 2 weeks of antibiotic therapy were included...

We describe a case report of a man aged 56 years with a 4-month history of right-sided sciatica-type pain with subclinical disc prolapse evident on MRI. Worsening pain together with the appearance of a tender mass in his right buttock prompted further imaging, which demonstrated an infiltrative mass engulfing the lumbosacral plexus. This was later shown to be a granulocytic sarcoma on biopsy. Intervertebral disc herniation can be an incidental finding and is not always the cause of sciatica.

Gene Ontology (GO) classification of statistically significantly differentially expressed genes is commonly used to interpret transcriptomics data as a part of functional genomic analysis. In this approach, all significantly expressed genes contribute equally to the final GO classification regardless of their actual expression levels. Gene expression levels can significantly affect protein production and hence should be reflected in GO term enrichment. Genes with low expression levels can also participate in GO term enrichment through cumulative effects...

There is a critical unmet clinical need for bladder cancer immunotherapies capable of inducing durable antitumor immunity. We have shown that four intravesical treatments with a simple co-formulation of interleukin-12 and the biopolymer chitosan not only destroy orthotopic bladder tumors, but also promote a potent long-lasting systemic immune response as evidenced through tumor-specific in vitro killing assays, complete protection from rechallenge, and abscopal antitumor responses at distant non-treated tumors...

Autoimmune pancreatitis (AIP) is a special type of chronic pancreatitis which is autoimmune mediated. The international consensus diagnostic criteria (ICDC) 2011 proposed two types of AIP: type I is associated with histological pattern of lymphoplasmacytic sclerosing pancreatitis (LPSP), characterized by serum IgG4 elevation, whereas type 2 is named idiopathic duct-centric pancreatitis (IDCP), with granulocytic epithelial lesion (GEL) and immunoglobulin G4 (IgG4) negative. The pathogenic mechanism is unclear now; based on genetic factors, disease specific or related antigens, innate and adaptive immunity may be involved...

Hematopoietic stem cells (HSCs) are mobilized from niches in the bone marrow (BM) to the blood circulation by the cytokine granulocyte colony-stimulating factor (G-CSF) through complex mechanisms. Among these, signals from the sympathetic nervous system regulate HSC egress via its niche, but how the brain communicates with the BM remains largely unknown. Here we show that muscarinic receptor type-1 (Chrm1) signaling in the hypothalamus promotes G-CSF-elicited HSC mobilization via hormonal priming of the hypothalamic-pituitary-adrenal (HPA) axis...

The immune system is complex and pervasive as it functions to prevent or limit infections in the human body. In a healthy organism, the immune system and the redox balance of immune cells maintain homeostasis within the body. The failure to maintain the balance may lead to impaired immune response and either over activity or abnormally low activity of the immune cells resulting in autoimmune or immune deficiency diseases. Compounds containing α,β-unsaturated carbonyl-based moieties are often reactive. The reactivity of these groups is responsible for their diverse pharmacological activities, and the most important and widely studied include the natural compounds curcumin, chalcone, and zerumbone...

Development of acute myeloid leukemia is usually sustained by deregulated epigenome. Alterations in DNA methylation and histone modifications are common manifestations of the disease. Acute promyelocytic leukemia (APL) is not an exception. Therefore, drugs that target epigenetic processes suggest an appealing strategy for APL treatment. In this study we tested the anti-leukemic activity of histone deacetylase inhibitor (HDACi) Belinostat (PXD101, (2E)-N-Hydroxy-3-[3-(phenylsulfamoyl)phenyl]prop-2-enamide), and histone methyltransferase inhibitor (HMTi) 3-Deazaneplanocin A (DZNep, 5R-(4-amino-1H-imidazo[4,5-c]pyridin-1-yl)-3-(hydroxymethyl)-3-cyclopentene-1S,2R-diol) combined with retinoic acid (RA) in APL cells NB4 and HL-60...

The prevalence of neurodegenerative disease and arthritis increases with age. Despite both processes being associated with immune activation and inflammation, little is known about the mechanistic interactions between neurodegenerative disease and arthritis. In this article, we show that tau-transgenic (tau-tg) mice that develop neurodegenerative disease characterized by deposition of tau tangles in the brain are highly susceptible to developing arthritis. Already at steady-state conditions, tau-tg mice exhibit peripheral immune activation that is manifested by higher numbers of granulocytes, plasmablasts, and inflammatory Ly6C(hi) CCR2(+) monocytes, as well as increased levels of proinflammatory cytokines, such as TNF-α and IL-17...

Neutrophil granulocytes are the first leukocytes that encounter and phagocytose Leishmania major (L. major) parasites in the infected skin. The parasites can nonetheless survive within neutrophils. However, the mechanisms enabling the survival of Leishmania within neutrophils are still elusive. Previous findings indicated that human neutrophils can engulf apoptotic cells. Since apoptotic neutrophils are abundant in infected tissues, we hypothesized that the uptake of apoptotic cells results in diminished anti-leishmanial activity and, consequently, contributes to enhanced survival of the parasites at the site of infection...

BACKGROUND: Mucosal and systemic immune mediators have been independently associated with HIV acquisition risk, but the relationship between compartments remains unclear. METHODS: To address this, the concentrations of 12 cytokines were compared in matched plasma and cervicovaginal lavages (CVLs) from 57 HIV-positive women before their acquisition of HIV (cases) and 50 women who remained uninfected (controls) during the CAPRISA 004 trial. RESULTS: Although genital IP-10 concentrations were significantly higher in cases, plasma IP-10 concentrations were inversely associated with HIV risk...
