Dendritic cell receptors

Dendritic cell (DC) receptors are a heterogeneous group of cell-surface proteins that play a pivotal role in the immune system by bridging innate and adaptive immunity (Worbs et al., 2017, Nature Reviews Immunology). These receptors include Pattern Recognition Receptors (PRRs) such as Toll-like receptors (TLRs) and C-type lectin receptors (CLRs), which are responsible for detecting pathogen-associated molecular patterns (PAMPs) and damage-associated molecular patterns (DAMPs) (Banchereau & Steinman, 1998, Nature). Upon ligand binding, these receptors initiate signaling cascades that lead to DC maturation, cytokine production, and the migration of DCs to lymph nodes for antigen presentation to T cells. In clinical practice, DC receptors are significant therapeutic targets; for example, TLR agonists like imiquimod are used to treat skin cancers and viral infections by stimulating local immune responses (StatPearls, 2023). Additionally, targeting C-type lectin receptors like DEC-205 or DC-SIGN with antibody-antigen conjugates is a strategy used in vaccine development to enhance antigen cross-presentation and T-cell activation (UniProt, 2024). However, therapeutic manipulation of these receptors carries risks, such as systemic cytokine release syndrome or the potential induction of autoimmune responses due to over-activation of the immune system.
