Olfactomedin 4 expression and functions in innate immunity, inflammation, and cancer.

Olfactomedin 4 (OLFM4) is an olfactomedin domain-containing glycoprotein. Multiple signaling pathways and factors, including NF-κB, Wnt, Notch, PU.1, retinoic acids, estrogen receptor, and miR-486, regulate its expression. OLFM4 interacts with several other proteins, such as gene associated with retinoic-interferon-induced mortality 19 (GRIM-19), cadherins, lectins, nucleotide oligomerization domain-1 (NOD1) and nucleotide oligomerization domain-2 (NOD2), and cathepsins C and D, known to regulate important cellular functions. Recent investigations using Olfm4-deficient mouse models have provid

Vascular repair and regeneration as a therapeutic target for pulmonary arterial hypertension.

The last decade has seen substantial changes in our understanding of the pathobiology of pulmonary arterial hypertension (PAH), a severe and devastating disease without curative treatment. It is now accepted that injury to the endothelial cells of the pulmonary arteries is central for the subsequent development of lumen-obliterative lung vascular lesions. A variety of circulating and lung-resident progenitor and stem cells likely contribute to vascular integrity, and evidence for the presence of cells expressing stem and progenitor cell markers is found inside and in the immediate vicinity of

The evolving role of plerixafor in hematopoietic progenitor cell mobilization.

The introduction of plerixafor as a peripheral blood stem cell mobilization agent has allowed more patients with multiple myeloma, non-Hodgkin's lymphoma, and Hodgkin's disease to mobilize sufficient hematopoietic progenitor cells (HPCs) to proceed to autologous transplantation. Because of the high cost of plerixafor, it is not routinely used in all patients undergoing HPC mobilization. If cost were not an issue, an argument could be made that plerixafor could be added to every mobilization regimen, but cost is an issue so in an attempt to be more cost-effective, many centers have limited pler

GM-CSF modulates pulmonary resistance to influenza A infection.

Alveolar type II epithelial or other pulmonary cells secrete GM-CSF that regulates surfactant catabolism and mucosal host defense through its capacity to modulate the maturation and activation of alveolar macrophages. GM-CSF enhances expression of scavenger receptors MARCO and SR-A. The alveolar macrophage SP-R210 receptor binds the surfactant collectin SP-A mediating clearance of respiratory pathogens. The current study determined the effects of epithelial-derived GM-CSF in host resistance to influenza A pneumonia. The results demonstrate that GM-CSF enhanced resistance to infection with 1.9×

[Indications of G-CSF administration in hematologic disorders].

Granulocyte colony stimulating factors (G-CSF) are largely used in the treatment of hematologic disorders to improve both the myelosuppression which might directly result from the disease or indirectly induced by the numerous chemotherapy regimen. G-CSF reduces the depth and duration of neutropenia in lymphoma patients and thus allows the design of more dose intense chemotherapy regimen which were shown to improve outcome particularly in patients with diffuse large B-cell and Hodgkin's lymphoma. G-CSF has been studied in patients with acute leukemias (ALL and AML) both concomitantly to inducti

Low dose melphalan is a treatment option in elderly patients with high risk myelodysplastic syndrome or secondary acute myeloblastic leukaemia.

We present the case of a 71 year-old man with secondary acute myeloblastic leukemia, who was successfully treated with low dose melphalan plus Epo plus G-CSF. We treated the patient with 2 mg of melphalan once a day orally, G-CSF 5 mg/kg 3 times a week and Epo 10.000 ui subcutaneously 3 times a week until the maximum response was obtained. Complete remission was achieved after 16 weeks of continuous treatment. Treatment-related toxicity was not significant. We recommend the use of low dose melphalan in elderly patients with high risk MDS as a treatment option.

Eosinophil activation in the tissue: synthetic steroid, budesonide, effectively inhibits the survival of eosinophils isolated from peripheral blood but not nasal polyp tissues.

We investigated the effect of a potent synthetic steroid, budesonide (BUD), on the survival of nasal polyp (NP) derived eosinophils (EOS). BUD, at the highest dose used, 10(-6) M, decreased this survival but only by approximately one third. We speculated that the relatively small inhibitory effect of budesonide on the survival of NP-EOS could be the result of these EOS being exposed to substantial amounts of GM-CSF, IL-5 or IL-3. In this regard, we detected 148 pg of GM-CSF per 150 mg of tissue, which approximately contained 106 of eosinophils, in the supernatant of NP explants for 24 h withou

Long-term bone marrow cultures in polycythaemia vera and essential thrombocythaemia.

Bone marrow samples of 8 patients with essential thrombocythaemia and three patients with polycythaemia vera were cultured in long-term bone marrow cultures. The production of non-adherent cells and colony-forming unit-granulocyte-macrophage harvested weekly did not differ from that of 29 healthy bone marrow transplant donors. There was a trend towards less complete stromal confluence in patients with a myeloproliferative disease.

[Current data on granulocytes donations].

Granulocyte transfusion is uncommon but essential for some aplastic patients with major infection and those with septic granulomatosis disease and visceral aspergillosis. Compatibility between donor and recipient (ABO, D, Kell blood type, cytomegalovirus) is necessary. Stimulation by dexamethasone, before use of GCSF, permits to obtain approximately 10 x 10(9) white cells per l. Doses of heparin must be calculated to ensure an efficient hypocoagulation without any trouble for the donor immediately after his donation. Sedimentation by hydroxyethylstarch is an unavoidable element to obtain the m

Kinetic analysis of cytokine gene expression in the livers of naive and immune mice infected with Listeria monocytogenes. The immediate early phase in innate resistance and acquired immunity.

The anamnestic response to infection with Listeria monocytogenes is characterized by the rapid elimination of normally lethal doses of bacteria and accelerated granuloma formation. These phenomena are mediated by listeria-specific memory T cells within the first 24 h after reinfection. In order to elucidate the mechanisms operative during this decisive phase of infection, we conducted a comprehensive kinetic and quantitative analysis of cytokine gene expression in the livers of naive and immune mice. Organs were removed at 30 min, and 1, 2, 6, and 24 h after primary and secondary infections, a

[Mechanism of protective effect of n-butanol extract of Pulsatilla Decoction on vaginal epithelial cells under Candida albicans stimulation through EGFR/MAPK pathway based on transcriptomics].

This study aimed to investigate the protective effect and its underlying mechanism of n-butanol extract of Pulsatilla Decoction(BEPD) containing medicinal serum on vaginal epithelial cells under Candida glabrata stimulation via the epidermal growth factor receptor/mitogen activated protein kinase( EGFR/MAPK) pathway based on transcriptomics. A vulvovaginal candidiasis(VVC) mouse model was established first and transcriptome sequencing was performed for the vaginal mucosa tissues to analyze the gene expression differences among the control, VVC model, and BEPD intervention groups. Simultaneousl

[Agranulocytosis as a complication of acute infectious mononucleosis].

INTRODUCTION: Acute infections mononucleosis is the most common clinical manifestation of primary Epstein-Barr virus (EBV) infection occurri … rate, and almost every case has been reported in the literature. Filgrastim--the recombinant human granulocyte colony-stimulating factor (G-CSF) stimulates the activation, proliferation and maturation of progenitor granulocyte cells. This drug is usually applied in treatment of iatrogenic neutropenia, during chemotherapy of malignancies and in some idiopathic and cyclic neutopenias. …

Effect of the CSF1R inhibitor PLX3397 on remyelination of corpus callosum in a cuprizone-induced demyelination mouse model.

Multiple sclerosis (MS) is a chronic inflammatory disease affecting the central nervous system (CNS). Despite introducing multiple immunomodulatory approaches for MS, there are still major concerns about possible ways for improving remyelination in this disease. Microglia exert essential roles in regulation of myelination processes, and interaction between colony-stimulating factor 1 (CSF1) with its receptor CSF1R is considered as a key regulator of microglial differentiation and survival. The aim of this study was to investigate possible roles for a CSF1R inhibitor PLX3397 in recovery of cent

Macrophage colony-stimulating factor increases hepatic macrophage content, liver growth, and lipid accumulation in neonatal rats.

Signaling via the colony-stimulating factor 1 receptor (CSF1R) controls the survival, differentiation, and proliferation of macrophages. Mutations in CSF1 or CSF1R in mice and rats have pleiotropic effects on postnatal somatic growth. We tested the possible application of pig CSF1-Fc fusion protein as a therapy for low birth weight (LBW) at term, using a model based on maternal dexamethasone treatment in rats. Neonatal CSF1-Fc treatment did not alter somatic growth and did not increase the blood monocyte count. Instead, there was a substantial increase in the size of liver in both control and

Mature T-lineage leukemia with growth factor-induced multilineage differentiation.

We report an acute T-lymphoblastic leukemia with a predominantly mature CD3+ CD7+ WT31+ phenotype that was induced to differentiate into different cell lineages by various recombinant human growth factors. In the presence of IL-3 or GM-CSF, the leukemic cells gave rise to myeloid and monocytic cells including terminally differentiated, partially functional, segmented neutrophilic granulocytes as assessed by morphologic, cytochemical, immunophenotypic, and functional criteria. In the presence of IL-2, leukemic granulated lymphoid cells exhibiting MHC-unrestricted cytotoxicity and expressing a C

Activation of peroxisome proliferator-activated receptors in human airway smooth muscle cells has a superior anti-inflammatory profile to corticosteroids: relevance for chronic obstructive pulmonary disease therapy.

Airway smooth muscle is actively involved in the inflammatory process in diseases such as chronic obstructive pulmonary disease and asthma by 1) contributing to airway narrowing through hyperplasia and hypertrophy and 2) the release of GM-CSF and G-CSF, which promotes the survival and activation of infiltrating leukocytes. Thus, the identification of novel anti-inflammatory pathways in airway smooth muscle will have important implications for the treatment of inflammatory airway disease. This study identifies such a pathway in the activation of peroxisome proliferator-activated receptors (PPAR

Biologic therapies for chronic inflammatory bowel disease.

Crohn's disease (CD) and ulcerative colitis (UC) make up the so-called chronic inflammatory bowel disease (IBD). Advances in the understanding of IBD pathophysiologic mechanisms in the last few years have allowed the development of novel therapies such as biologic therapies, which at least theoretically represent a more specific management of this disease with fewer side effects. Currently, the only effective and widely accepted biologic therapy for the treatment of intraluminal, fistulizing CD, both for remission induction and maintenance, is infliximab. The role of other monoclonal antibodie
