Fluorescent chemical probes are used nowadays as a chemical resource to study the physiology and pharmacology of several important endogenous receptors. Different fluorescent groups have been coupled with known ligands of these receptors, allowing the visualization of their localization and trafficking. One of the most important molecular players of innate immunity and inflammation are the Toll-Like Receptors (TLRs). These Pattern-Recognition Receptors (PRR) have as natural ligands microbial-derived pathogen-associated molecular patterns (PAMPs) and also endogenous molecules called danger-associated molecular patterns (DAMPs). These ligands activate TLRs to start a response that will determine the host’s protection and overall cell survival but can also lead to chronic inflammation and autoimmune syndromes. TLRs action is tightly related to their subcellular localization and trafficking. Understanding this trafficking phenomenon can enlighten critical molecular pathways that might allow to decipher the causes of different diseases. In this chapter, the study of function, localization and trafficking of TLRs through the use of chemical probes will be discussed. Furthermore, an example protocol of the use of fluorescent chemical probes to study TLR4 trafficking using high-content analysis will be described.

Abstract

Fluorescent chemical probes are used nowadays as a chemical resource to study the physiology and pharmacology of several important endogenous receptors. Different fluorescent groups have been coupled with known ligands of these receptors, allowing the visualization of their localization and trafficking. One of the most important molecular players of innate immunity and inflammation are the Toll-Like Receptors (TLRs). These Pattern-Recognition Receptors (PRR) have as natural ligands microbial-derived pathogen-associated molecular patterns (PAMPs) and also endogenous molecules called danger-associated molecular patterns (DAMPs). These ligands activate TLRs to start a response that will determine the host’s protection and overall cell survival but can also lead to chronic inflammation and autoimmune syndromes. TLRs action is tightly related to their subcellular localization and trafficking. Understanding this trafficking phenomenon can enlighten critical molecular pathways that might allow to decipher the causes of different diseases. In this chapter, the study of function, localization and trafficking of TLRs through the use of chemical probes will be discussed. Furthermore, an example protocol of the use of fluorescent chemical probes to study TLR4 trafficking using high-content analysis will be described.
