Lipid mediators variedly affect adipocyte differentiation. Anandamide stimulates adipogenesis via CB1 receptors and peroxisome proliferator-activated receptor γ. Anandamide may be converted by PTGS2 (COX2) and prostaglandin F synthases, such as prostamide/prostaglandin F synthase, to prostaglandin F2α ethanolamide (PGF2αEA), of which bimatoprost is a potent(More)
Dendritic cells (DCs) are central players in coordinating immune responses, both innate and adaptive. While the role of lipid mediators in the immune response has been the subject of many investigations, the precise role of prostaglandins has often been plagued by contradictory studies. In this study, we examined the role of PGE(2) on human DC function.(More)
Granulocyte-macrophage colony-stimulating factor (GM-CSF) can induce the generation and activation of dendritic cells (DCs), the most potent of antigen presenting cells (APCs). Tumors secreting GM-CSF have been shown to induce strong anti-tumor immune responses. In this report, we have constructed a glycosylphosphatidyl-inositol (GPI) anchored form of(More)
The addition of immunostimulatory molecules to tumor cells has been proposed as a potentially useful strategy to induce anti-tumor immunity. In this report we have investigated the application of using isolated tumor membranes modified by transfer of a glycosyl-phosphatidylinositol (GPI)-anchored form of the costimulatory molecule, B7-1 (CD80), as a cell(More)
A major step in purifying membrane bound proteins involves the solubilization of the protein of interest from the cell membranes. Glycosylphosphatidyl inositol (GPI)-anchored proteins pose a singular problem in this solubilization step since they are found in detergent-resistant membrane complexes and accordingly are insoluble in cold Triton X-100. In this(More)

Prostamide (prostaglandin ethanolamide) research emerged from two distinct lines of research: 1) the unique pharmacology of the antiglaucoma drug bimatoprost and 2) the discovery that endocannabinoid anandamide was converted by COX-2 to a series of electrochemically neutral prostaglandin (PG) ethanolamides. Bimatoprost pharmacology was found to be virtually(More)
Advances in the understanding of the immune response to tumors has led to the development of new strategies to design therapeutic vaccines. One of these strategies is the development of protein transfer of immunostimulatory molecules onto the surface of tumor cells, thereby directing the immune response to the tumor antigens carried by the modified tumor(More)
Functional analysis of a clinical microbiome facilitates the elucidation of mechanisms by which microbiome perturbation can cause a phenotypic change in the patient. The direct approach for the analysis of the functional capacity of the microbiome is via shotgun metagenomics. An inexpensive method to estimate the functional capacity of a microbial community(More)
PURPOSE To investigate the therapeutic potential of a prostacyclin (IP) receptor agonist for ocular inflammation and the effect on immune cells. METHODS The anti-inflammatory activities of cicaprost were determined in primary human monocyte-derived macrophages and human monocyte-derived dendritic cells (MoDC), as well as a lipopolysaccharides(More)
Prostaglandin E2 (PGE2)-2-glyceryl ester is a cyclo-oxygenase 2 product of the endocannabinoid 2-arachidonyl glycerol. It is claimed as pharmacologically novel, but this is complicated by rapid and irreversible isomerization to the 1(3) ester. For ocular studies, enzymatic hydrolysis of the ester moiety creates an additional complication. PG-glyceryl esters(More)
