WebDec 1, 2004 · A class of PRRs called Toll-like receptors (TLRs) has the ability to recognize pathogens or pathogen-derived products and initiate signaling events leading to activation of innate host defenses. Signaling by TLRs initiates acute inflammatory responses by induction of anti-microbial genes and inflammatory cytokines and chemokines [2], [3]. Dendritic cells are derived from hematopoietic bone marrow progenitor cells (HSC). These progenitor cells initially transform into immature dendritic cells. These cells are characterized by high endocytic activity and low T-cell activation potential. Immature dendritic cells constantly sample the surrounding environment for pathogens such as viruses and bacteria. This is done through p…
