Effect of prolonged in vivo administration of leukocyte interferon on the mitogen responsiveness of human lymphocytes.
Peripheral lymphocytes from patients with osteosarcoma receiving interferon (IF) as adjuvant therapy were tested in vitro for response to various mitogens. Prolonged parenteral administration of IF preparations caused no major change of the mitogen responses. The ability of IF, when added in vitro, to inhibit lymphocyte response to mitogens was not altered to any major extent by in vivo administration of IF.
