Abstract
Dendritic cells (DCs) sense the presence of pathogens through germline-encoded pattern recognition receptors (PRRs), which recognize molecular patterns expressed by various microorganisms and endogenous stimuli. Toll-like receptors (TLRs) are the best characterized PRRs. TLR activation has a profound effect on a number of DC activities, including endocytosis, cytoskeleton rearrangement, migration, antigen processing and presentation, survival, and death. The goal of TLR-induced DC reprogramming is to promote the appropriate activation and differentiation of lymphocytes bearing clonally distributed antigen-specific receptors. In this review, we will focus on the functional consequences of TLR engagement for conventional DCs.
