Rationale: Clonal hematopoiesis driven by mutations of DNMT3A (DNA methyltransferase 3a) is associated with increased incidence cardiovascular disease and poor prognosis patients chronic heart failure (HF) aortic stenosis. Although experimental studies suggest that clonal hematopoiesis–driver may enhance inflammation, specific signatures inflammatory cells in humans are missing. Objective: To d...
Immunopathogenesis of Erdheim-Chester disease (ECD), a rare non-Langerhans cell histiocytosis, is poorly known. In previous studies, various cytokines were detected in ECD lesions, presumably orchestrating lesional histiocyte recruitment. Because ECD lesions are frequently associated with systemic symptoms, we postulated that underlying global immune perturbations might also be revealed. We qua...
Monocytic adhesion and chemotaxis are regulated by MAPK pathways, which in turn are controlled by redox-sensitive MAPK phosphatases (MKPs). We recently reported that metabolic disorders prime monocytes for enhanced recruitment into vascular lesions by increasing monocytes' responsiveness to chemoattractants. However, the molecular details of this proatherogenic mechanism were not known. Here we...
BACKGROUND AND AIMS Liver and systemic inflammatory factors influence monocyte phenotype and function, which has implications for hepatic recruitment and subsequent inflammatory and fibrogenic responses, as well as host defence. METHODS Peripheral blood monocyte surface marker (CD14, CD16, CD163, CSF1R, CCR2, CCR4, CCR5, CXCR3, CXCR4, CX3CR1, HLA-DR, CD62L, SIGLEC-1) expression and capacity f...
The Effect of Monophosphoryl Lipid A on Maturation of DCs from Patients with Acute Myeloid Leukaemia
Background: Generation of monocyte-derived dendritic cells (MDDC) is induced in the presence of GM-CSF and IL-4, and a maturation stimulus is added to the monocyte culture to obtain mature Dendritic Cells (DCs) suitable for therapy. TNF-α is the most common cytokine used for activating DCs and generating mature MDDC either alone or in combination with other cytokines. Objective: To compare effe...
