Echinacea alkylamides inhibit interleukin-2 production by Jurkat T cells.
Alkylamides present in Echinacea species have reported immunomodulatory actions, yet their direct effects on T lymphocytes, key mediators of antiviral immunity, are poorly understood. We hypothesized that constituents present in ethanolic extracts of Echinacea species exert direct immunomodulatory effects on human Jurkat T cells. Modulation of IL-2 production by submaximally stimulated Jurkat c...
متن کاملProfile of interleukin-2 production in human mononuclear cells and T-cell lines
Introduction: Interleukin-2 (IL-2) as a T helper type 1 (Th1) cytokine has an important role Background and Objective: Interleukin-2 (IL-2) as a T helper type 1 (Th1) cytokine has an important role in activation, growth and differentiation of several immune cells. Moreover IL-2 is known as a pro-inflammatory and anti-tumoral cytokine. In addition deysregulation of IL-2 in some diseases such as ...
متن کاملAnti-complementary activity of triterpenoides from fruits of Zizyphus jujuba.
In order to determine on the anti-complement activity of triterpenes, following eleven triterpenoides were isolated from the fruits of the Zizyphus jujuba MILL: ceanothane-type triterpenes: colubrinic acid (1), zizyberenalic acid (11); lupane-type triterpenes: alphitolic acid (2), 3-O-cis-p-coumaroyl alphitolic acid (3), 3-O-trans-p-coumaroyl alphitolic acid (4), betulinic acid (7), betulonic a...
متن کاملClausmarin A, Potential Immunosuppressant Revealed by Yeast-Based Assay and Interleukin-2 Production Assay in Jurkat T Cells
Small-molecule inhibitors of Ca2+-signaling pathways are of medicinal importance, as exemplified by the immunosuppressants FK506 and cyclosporin A. Using a yeast-based assay devised for the specific detection of Ca2+-signaling inhibitors, clausmarin A, a previously reported terpenoid coumarin, was identified as an active substance. Here, we investigated the likely mechanism of clausmarin A acti...
متن کاملInduction of interleukin 2 production but not methionine adenosyltransferase activity or S-adenosylmethionine turnover in Jurkat T-cells.
We have recently reported that methionine adenosyltransferase (MAT) in resting human peripheral blood T-cells is primarily present in the form of a precursor which we named lambda. This protein decreases upon cell stimulation, as both MAT activity and the amount of the catalytic alpha/alpha' subunits of the enzyme increase. When resting cells are activated by phytohemagglutinin, the decrease in...
