Interaction of MAMPs with TLRs expressed on dendritic cells (DCs)

Data is available on the interaction between microorganism-associated molecular patterns and individual toll-like receptors on dendritic cells that turn on signal transduction pathways leading to the activation of different transcription factors.

Microbial invasions are perceived by pattern recognition receptor (PRR)-expressing cells of the innate immune system. PRRs bind a number of microbial products collectively referred to as microorganism-associated molecular patterns (MAMPs). Toll-like receptors (TLRs) are the best-characterized PRRs. The interaction of MAMPs with TLRs expressed on dendritic cells (DCs) plays a particularly important role in regulation of immune responses. By interacting with different combinations of adapter proteins, individual TLRs turn on signal transduction pathways leading to the activation of different transcription factors, such as nuclear factor (NF)-kB, activation protein (AP)-1, and interferon regulatory factors (IRFs).
