Progress in biology of dendritic cells / 中国实验血液学杂志

ABSTRACT

As the most potent antigen-presenting cells (APC), dendritic cells are important in launching both humoral and cellular immune responses against tumor. Although the high evaluation of DC in immunotherapy for cancer by means of DC vaccines, more studies have indicated DC is a heterogeneous population and proved that DC subsets are prominent determinants for the effectiveness of immune responses. Different DC subsets display different receptors and surface molecules, and express different sets of cytokines/chemokines, which result in distinct immunological outcomes. Clinical trials with ex vivo generated DC vaccines also manifest unexpected immunological tolerance as well as allergic response. It is essential to study the biological aspects of human DC subsets, which may be a key to the generation of novel DC-based vaccines. In this article, the progress of studies on biology of dendritic cells including their origins, differentiation, function and application of DC subsets is reviewed.
