abstract：:Dendritic cells (DCs) are highly specialized antigen-presenting cells that play a key role in the initiation and regulation of immune responses. The ability of DCs to process antigens and the outcome of their interaction with T cells are largely dependent on phenotype as well as maturation state of DCs. In this study,...
