Prostaglandin suppression of mitogen-stimulated lymphocytes in vitro. Changes with mitogen dose and preincubation.
In this study we further characterize the properties of the prostaglandin-producing suppressor cell. Overnight preincubation of peripheral blood mononuclear cells results in an increased response of the cells to phytohemagglutinin or Concanavalin A compared to the response of fresh cells. This increase in mitogen response with preincubation was similar in magnitude to the increase in mitogen re...
متن کاملIn vitro effects of fluticasone propionate on IL-13 production by mitogen-stimulated lymphocytes.
BACKGROUND Corticosteroid administration produces multiple immunomodulatory effects, including down-regulation of cytokine production by CD4 T lymphocytes. Fluticasone propionate (FP) (Glaxo Smith&Kline, Greenford, UK), a highly lipophilic topical corticosteroid, has been shown to be safe and effective in the treatment of asthma and of both seasonal and perennial rhinitis. AIMS To gain insigh...
متن کاملPhosphoinositide hydrolysis in mitogen-stimulated human peripheral-blood T lymphocytes.
Both phytohaemagglutinin and antibodies to the CD3 molecule induced proliferation and phosphoinositide hydrolysis in human peripheral-blood T lymphocytes, but the magnitude of the inositol phosphate response was small and the rate of accumulation slow [significant increases in Ins(1,4,5)P3 were observed only after 10 min]. Hence this response differs from the well-characterized Ins(1,4,5)P3 res...

the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...
15 صفحه اولRelease of prostaglandin by mitogen- and antigen-stimulated leukocytes in culture.
The prostaglandin (PG) content of mitogen- and antigen-stimulated leukocyte cultures was examined by a radioimmunoassay procedure empolying an antiserum reactive with PGB(1) and PGB(2), the alkaline dehydration products of PGE and PGA. At 48 h, mitogen-activated mouse spleen cell cultures showed 2-10-fold increases in the PGE, but not in the PGA, component of immunoreactive PG (iPG) fractionate...
