Abstract Purpose: We aimed to establish whether programmed cell death-1 (PD-1) and death ligand 1 (PD-L1) expression, in ovarian cancer tumor tissue blood, could be used as biomarkers for discrimination of histology prognosis cancer. Experimental Design: Immune cells were separated from ascites, obtained women with suspected studied the differential expression possible immune using flow cytometry. PD-L1 on tumor-associated inflammatory was assessed by immunohistochemistry microarray. Plasma...

Epithelial ovarian cancer (EOC) is the most lethal of all gynecological malignancies in UK. Recent evidence has shown that there potential for immunotherapies to be successful treating this cancer. We have previously effective application combinations traditional chemotherapy and CAR (chimeric antigen receptor) T cell immunotherapy vitro vivo models EOC. Platinum-based synergizes with ErbB-targeted cells (named T4), significantly reducing tumor burden mice. Here, we show paclitaxel T4 as...

Elevation of intracellular Ca2+ concentration induces the synthesis N-arachydonoylethanolamine (anandamide) in a subpopulation primary sensory neurons. N-acylphosphatidylethanolamine phospholipase D (NAPE-PLD) is only known enzyme that synthesizes anandamide -dependent manner. NAPE-PLD mRNA as well anandamide's main targets, excitatory transient receptor potential vanilloid type 1 ion channel (TRPV1), inhibitory cannabinoid (CB1) receptor, and anandamide-hydrolyzing fatty acid amide...

Our previous finding, that the capsaicin- and KCl-induced Ca(2+)-dependent production of intra- intercellular signaling molecule N-arachidonoyl ethanolamine (anandamide) in cultured primary sensory neurons could be abolished reduced by approximately 2/3 capsaicin-induced degeneration capsaicin-sensitive neurons, respectively suggests a major sub-population cells together with group non-capsaicin-sensitive should express enzymes involved anandamide synthesis. N-acyl phosphotidylethanolamine...
