Multiple clinically applicable methods have been used to induce dendritic cells (DCs) to express whole cell tumor antigens, including pulsing DCs with tumor lysate, and mixing DCs with apoptotic or live tumor cells. Herein we demonstrate, using two different tumor systems, that these methods are equipotent inducers of systemic antitumor immunity. Furthermore, tumor lysate pulsed DC vaccines generate more potent antitumor immunity than immunization with irradiated tumor cells plus the classic adjuvant, Corynebacterium parvum.

T Cell Activation and Clonal Selection

T cells are integral to our adaptive immune system, recognizing and effectively responding to foreign antigens. T cell activation and clonal selection are pivotal in orchestrating this immune response. This article elucidates these mechanisms, detailing the roles of cluster of differentiation (CD) markers, major histocompatibility complex (MHC) molecules, costimulatory signals, and the process of clonal selection.
