Production of interleukin-1 receptor antagonist and interleukin-1 beta by peripheral blood mononuclear cells is differentially regulated.
We studied the relationship between the production of the 23-Kd interleukin-1 receptor antagonist (IL-1ra) and IL-1 beta in cultures of human peripheral blood mononuclear cells (PBMC) using a specific radioimmunoassay for IL-1ra that had a sensitivity of 166 +/- 11 pg/mL. PBMC cultured without human serum made little IL-1ra or IL-1 beta. In the presence of 1% AB serum, there was no increase in ...
متن کاملThe kinetics of interleukin 1 secretion from activated monocytes. Differences between interleukin 1 alpha and interleukin 1 beta.
We have performed pulse-chase experiments to investigate the secretion and processing of interleukin 1 (IL-1) by human peripheral blood monocytes. Polyclonal antisera generated against either recombinant IL-1 alpha (p15) or IL-1 beta (p17) could distinguish the two isoelectric forms in lysates and supernatants of lipopolysaccharide-activated monocytes. In agreement with previous results, no pro...

بیمه گران همیشه بابت خسارات بیمه نامه های تحت پوشش خود نگران بوده و روش هایی را جستجو می کنند که بتوانند داده های خسارات گذشته را با هدف اتخاذ یک تصمیم بهینه مدل بندی نمایند. در این پژوهش توزیع های فیزتایپ در مدل بندی داده های خسارات معرفی شده که شامل استنباط آماری مربوطه و استفاده از الگوریتم em در برآورد پارامترهای توزیع است. در پایان امکان استفاده از این توزیع در مدل بندی داده های گروه بندی ...
J chain synthesis and secretion of hexameric IgM is differentially regulated by lipopolysaccharide and interleukin 5.
Two functional polymeric forms of IgM can be produced by antibody-secreting B cells. Hexameric IgM lacks detectable J (joining) chain and activates complement 17-fold better than pentameric IgM, which usually contains one J chain per pentamer. Using the inducible B-cell lymphoma CH12, we determined if the synthesis of a particular polymeric form of IgM is a fixed property of B cells or can be a...
متن کاملSalmonella DNA adenine methylase mutants confer cross-protective immunity.
Salmonella isolates that lack or overproduce DNA adenine methylase (Dam) elicited a cross-protective immune response to different Salmonella serovars. The protection afforded by the Salmonella enterica serovar Typhimurium Dam vaccine was greater than that elicited in mice that survived a virulent infection. S. enterica serovar Typhimurium Dam mutant strains exhibited enhanced sensitivity to med...
