Extravasation of intravascular fluid mediated by the systemic administration of recombinant interleukin 2.

摘要: Adoptive immunotherapy with lymphokine-activated killer cells and recombinant interleukin 2 (IL 2) can produce significant reduction of visceral metastases in tumor-bearing mice and, as shown recently, in humans with disseminated cancer. Because further dose escalations of IL 2 have been prevented by the development of a vascular leak syndrome (VLS) in both mice and humans, we investigated this VLS in mice undergoing the systemic administration of high-dose IL 2. A model for quantitating capillary permeability was used in which 125I …
