Abstract
Responses in vitro to partially purified porcine leucocyte catabolin were studied in pig synovial fibroblasts.In serum-free cultures catabolin was found to stimulate secretion of prostaglandin E2 (PGE2) in a time and concentration-dependent manner. The initial stimulation of PGE2 secretion occurred only after a latent interval of six hours. In the same cell line catabolin was found to have no effect on the production of cyclic adenosine monophosphate (cAMP) at times ranging from 30 s to 20 min, even at concentrations up to 15 times greater than that required to promote accelerated release of glycosaminoglycans from cultured bovine nasal cartilage. It is therefore concluded that in pig synovial fibroblasts catabolin evokes a delayed secretion of PGE2 but does not alter cyclic AMP production.
摘要
在猪滑膜成纤维细胞中研究了其对部分纯化的猪白细胞分解代谢产物的体外反应。在无血清培养中，发现分解代谢产物以时间和浓度依赖的方式刺激前列腺素E2（PGE2）的分泌。PGE2分泌的初始刺激仅在6小时的潜伏期后才出现。在同一细胞系中，发现分解代谢产物在30秒至20分钟的时间范围内对环磷酸腺苷（cAMP）的产生没有影响，即使浓度高达促进从培养的牛鼻软骨中加速释放糖胺聚糖所需浓度的15倍。因此得出结论，在猪滑膜成纤维细胞中，分解代谢产物引起PGE2的延迟分泌，但不会改变cAMP的产生。
