摘要: Publisher Summary This chapter examines the antigenic structure of tumors and uses immunology to define differences between normal malignant cells study variability among themselves. Some these are best observed by intraspecific differences. most important modifications involve changes that not recognizable as antigenically different homologous species. would apply deletion any antigens do act histocompatibility probably applies all organ-specific antigens. The ability host react against an autochthonous tumor in immunological sense implies growth must have antigen lacks. shows such is for individual genetically identical with primary before it can be claimed potentialities initiation autoimmune response. It concludes contribute cancer research numerous ways. As a tool, has studying their precursors hence progression.
