Ischemic brain injury causes local inflammation, which involves activation of resident microglia, leukocyte, and monocyte infiltration. Involvement of peripheral immune cells in ischemia‐induced damage and repair is debatable. Using flow cytometry, gene expression profiling, and immunocytochemistry, we show that microglia predominate in the ischemic brain and express inflammation mediators at Day...
The central nervous system (CNS) contains several types of immune cells located in specific anatomic compartments. Macrophages reside at the CNS borders surrounding the brain vessels, in leptomeningeal spaces and the choroid plexus, where they interact with the vasculature and play immunological surveillance and scavenging functions. We investigated the phenotypic changes and role of these macrophages...
Multiple myeloma (MM) is a plasma cell malignancy characterized by bone marrow infiltration and the presence of a monoclonal protein in serum and/or urine. CXCR4 and its ligand CXCL12 are essential for neoplastic cell homing to bone marrow in haematological malignancies. The JAK2/STAT3 pathway, which is activated after CXCL12 binding to CXCR4, takes part in many signalling cascades which are linked...
Peripheral blood mobilized by cytokines (i.e. granulocyte colony stimulating factor, G-CSF) and chemotherapy has become a major source of hematopoietic stem and progenitor cells for transplantation (PBPCT). In this study the effect of the G-CSF receptor (CSF3R) gene polymorphism was investigated. The presence of the CSF3R variant (T allele, rs3917924) was related to CD34 + mobilization yield...
