Dendritic cells (DCs) are pivotal members of the immune system, serving as the sentinels that detect foreign pathogens and initiate the body's immune response. DCs express a myriad of surface molecules, collectively referred to as DC markers, which are crucial for their function. These markers include adhesion molecules, costimulatory molecules, and antigen-presenting molecules, each playing a distinct role in the activation and maturation of these immune cells. Unique DC markers are used as identifiers in various research contexts to isolate and study dendritic cell populations. The presence and density of these markers can change dynamically in response to environmental signals and intracellular events, indicating the functional state of the DCs. Understanding the regulation of DC marker expression is essential for uncovering the mechanisms underlying immune responses and for advancing our knowledge of immunology.
Several chemical agents are known to induce the expression of DC markers, thereby stimulating dendritic cells to achieve a mature phenotype capable of effectively presenting antigens and activating T-cells. Compounds such as lipopolysaccharide (LPS) and polyinosinic-polycytidylic acid (Poly I:C) are recognized for their ability to mimic bacterial and viral components, respectively, leading to the activation of dendritic cells via Toll-like receptors (TLRs). Other compounds, including imiquimod and resiquimod, function as synthetic ligands that bind to TLRs and stimulate dendritic cell maturation. Natural substances like vitamin D3 and β-glucan also play roles in modulating DC marker expression, with vitamin D3 activating nuclear receptors that influence gene transcription, and β-glucan engaging with cell surface receptors to promote the dendritic cell activation cascade. These activators are valuable tools in research, providing insight into the pathways that govern dendritic cell behavior and the immune system's response to various stimuli.
