The ability of the stimulated cells to produce interleukin-2 (IL-2) was determined using murine indicator cell lines. IL-2 receptor expression by mitogen-stimulated canine PBL was confirmed by the binding of hrIL-2 with high affinity, and with characteristics comparable to those of the human and murine IL-2 receptor. Examination of serum and PBL from two dogs that were treated with hrIL-2 and human recombinant tumor necrosis factor for systemic mast cell tumors showed that in one dog, IL-2 could be measured in the serum. Concurrently, the in vitro mitogenic response of this dog's PBL to hrIL-2 occurred earlier, possibly reflecting an increase in the relative number of IL-2-responsive cells within the PBL population.</style></abstract><issue><style face="normal" font="default" size="100%">1-2</style></issue><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/1632072?dopt=Abstract</style></custom1></record></records></xml>
