项目摘要

Significant focus is being placed on the utility of in vitro models to assess immunomodulation. In vitro cytokine release assays were used to evaluate the ability of 18 perfluoroalkyl substances to modulate cell proliferation and cytokine secretion in human peripheral blood lymphocytes. In vitro cytokine release assays were also used to screen for biological activity in several batches of echinacea purpurea. Results from the in vitro screen and endotoxin assessments were used to select a test article for in vivo studies. We have partnered with the Interagency Coordination Committee on the Validation of Alternative methods and are using recently published combinations of non-proprietary in vitro assays to evaluate the potential for a variety of chemicals to induce skin sensitization. Nominations were received from multiple ICCVAM agency partners and industry collaborators. Approximately 200 compounds are being screened in multiple assays. Draft reports for studies on formulations received through an industry collaboration and Isothiozolinone compounds nominated by the Environmental Protection agency have been received, reviewed and are undergoing finalization.

将重点放在体外模型评估免疫调节的实用性上。体外细胞因子释放测定法用于评估18种全氟烷基物质调节人外周血淋巴细胞中细胞增殖和细胞因子分泌的能力。体外细胞因子释放测定法也用于筛选几批紫锥菊紫癜中的生物学活性。体外筛查和内毒素评估的结果用于选择用于体内研究的测试文章。我们已经与替代方法验证的机构间协调委员会合作，并使用了最近发表的非专有体外测定法组合，以评估各种化学物质诱导皮肤敏化的潜力。来自多个ICCVAM代理合作伙伴和行业合作者的提名。大约有200种化合物在多个测定中筛选。通过行业合作和由环境保护署提名的异硫酸苯酮化合物收到的制剂的研究草案已被收到，审查并正在完成。
