Characteristics of DC immunisation. (A) Tumour growth was monitored in allografted mice immunised on days +7 and +14 (dashed lines) with naïve (DCnaive n=12 and n=8, respectively) and tumour-pulsed DC (DCneuro2a n=17 and n=16, respectively) as delineated by the arrows. (B) Proliferation of splenic lymphocytes from mice immunised on days +7 (n=9) and +14 (n=5) with tumour-pulsed DC in response to mitogenic stimulation with ConA, and restimulation with tumour-pulsed DC (DCneuro2a) in vitro. (C) Neuro-2a cell lysis as determined from LDH release by lymphocytes from allografted mice immunised with naïve (antigen-inexperienced) and tumour-pulsed DC on day +7 (n=5) and upon restimulation with tumour-pulsed DC in vitro. Assays were performed at a target:effector ratio of 1 : 50. (D) Tumour size in allografted mice (allo-BMT, n=21), after subcutaneous (SC, n=14) and intravenous (IV, n=11) immunisation with donor DC on day +7 post transplantation.
