研究领域
雷德菲尔德博士积极致力于人类慢性病毒感染的临床研究和临床治疗,尤其是HIV感染。他的主要研究领域是研制新型生物疗法治疗慢性病毒病原体疾病,尤其是具有潜在治疗价值的针对宿主细胞特异路径的疗法。其他转化医学研究领域包括:针对核苷酸生物合成的关键生化途径以提高抗逆转录药物治疗效果;靶向细胞活化并阻滞特定细胞周期的主要治疗策略;利用G1细胞周期阻滞剂来降低主要HIV宿主细胞受体的表达;利用G1细胞周期阻滞来提高HIV进入抑制剂的抗病毒活性;使用HIV蛋白作为治疗疫苗。
雷德菲尔德博士同时还积极进行临床研究,包括HIV替代治疗策略,以提高治疗效果,并进行新的抗病毒药物在艾滋病治疗作用方面的评估。他领导的临床研究机构已经进行了超过30次干预试验。雷德菲尔德博士的研究的最终目标是为美国及包括发展中国家在内各国艾滋病感染者及其他慢性病毒感染者,提供可持续的治疗方法。
目前,雷德菲尔德博士主持了一系列广泛的临床研究项目,,向巴尔的摩-华盛顿地区的超过4000名患者提供HIV护理和治疗。他还主持了美国“总统艾滋病紧急救援计划”的一个治疗项目,在非洲和加勒比地区的9个国家开展,为多达50000名的HIV人群提供高效抗逆转录病毒治疗。有针对性的项目评估和操作性的研究提高了治疗项目的效果。
雷德菲尔德博士是美国总统艾滋病顾问委员会的成员,同时他也是该委员会国际分部的主席。他刚刚完成在美国国立卫生研究院(NIH)艾滋病研究办公室顾问委员会和美国国立卫生研究院(NIH)Fogarty国际中心顾问委员会的任职。

Research Interests:
Dr. Redfield has been actively engaged in clinical research and clinical care of chronic human viral infections, especially HIV. His dominant area of research interest is the development of novel biological approaches to the treatment of chronic viral pathogens with a particular focus of targeting host cell pathways for their therapeutic potential. Several novel areas under active translation investigation include: targeting key biochemical pathways of nucleotide biosynthesis to enhance activity of specific antiretroviral medication; targeting cell activation with specific cell cycles as a primary treatment target; use of G1 cell cycle agents to down regulate expression of key HIV host cell receptors; use of G1 cell cycles to enhance antiviral activity of HIV entry inhibitors; and the use of HIV specific proteins as therapeutic vaccines.
Dr. Redfield is also actively involved in clinical research focused on the evaluation of alterative HIV-treatment strategies designed to improve treatment outcome and the evaluation of new commercially developed antiviral medications. The clinical research unit which he oversees has more than 30 active intervention trials. Dr. Redfield’s research focus is driven by his goal to develop durable treatment for persons living with HIV infection and other chronic viral infections in the US and throughout the world, including resource-limited settings.
Presently, Dr. Redfield oversees an extensive clinical program providing HIV care and treatment to more than 4,000 patients in the Baltimore–Washington community. He also oversees an extensive care and treatment program as part of the President’s Emergency Plan for AIDS Relief, which is active in 9 countries in Africa and the Caribbean and is now providing ARV treatment to more than 50,000 perople living with HIV. Treatment programs outcome improvement is driven by targeted program evaluation and operational research.
Dr Redfield serves as a member of the Presidential Advisory Council on HIV/AIDS as well as being the Chair of the International Subcommittee. He has also recently completed terms on NIH’s Advisory Council for the Office of AIDS Research and the Advisory Board of the NIH’s Fogarty International Center.
