Microglial cells are the resident macrophages of the central nervous system (CNS). Besides their classical roles in pathological conditions, these immune cells also dynamically interact with neurons and influence their structure and function in physiological conditions. The neuronal chemokine fractalkine and its microglial receptor CX3CR1 are one important signaling pathway involved in these re...
Human cytomegalovirus (CMV) infection has been linked to inflammatory diseases, including vascular disease and chronic transplant rejection, that involve vascular endothelial damage. We have previously shown that the host CD4(+) T-cell response to CMV antigen can produce IFNgamma and TNFalpha at levels sufficient to drive induction of fractalkine, a key marker of inflammation in endothelial cel...
Hypothalamic inflammation is a common feature of experimental obesity. Dietary fats are important triggers of this process, inducing the activation of toll-like receptor-4 (TLR4) signaling and endoplasmic reticulum stress. Microglia cells, which are the cellular components of the innate immune system in the brain, are expected to play a role in the early activation of diet-induced hypothalamic ...
Epithelial ovarian carcinoma (EOC) is a deadly disease, and little is known about the mechanisms underlying its metastatic progression. Using human specimens and established cell lines, we determined that the G-protein-coupled seven-transmembrane fractalkine receptor (CX(3)CR1) is expressed in primary and metastatic ovarian carcinoma cells. Ovarian carcinoma cells robustly migrated toward CX(3)...
Cells undergoing apoptosis are efficiently located and engulfed by phagocytes. The mechanisms by which macrophages, the professional scavenging phagocytes of apoptotic cells, are attracted to sites of apoptosis are poorly defined. Here we show that CX3CL1/fractalkine, a chemokine and intercellular adhesion molecule, is released rapidly from apoptotic lymphocytes, via caspase- and Bcl-2-regulate...
The precise mechanisms of cortical damage in multiple sclerosis (MS) remain unknown. Microglia, the resident immune cells in the central nervous system (CNS), are involved in the chronic neuroinflammation in MS cortical lesions. Microglia produce various inflammatory cytokines such as IFN-γ and IL-β, reactive oxygen species, and glutamate. IL-β secretion is induced by NLRP3. ROS is induced by G...
