Antigen-presenting cell uptake enhancement

"Antigen-presenting cell uptake enhancement" refers to strategies or interventions aimed at increasing the efficiency of antigen internalization by APCs such as dendritic cells, macrophages, and B cells. Enhanced uptake is often achieved by targeting specific receptors on APCs (including Fcγ receptors, C-type lectin receptors like DEC-205, or B cell receptors[1][4][5][6]) via engineered delivery platforms or adjuvants. This process results in greater expression of MHC-peptide complexes, costimulatory molecules, and cytokine secretion, collectively boosting the ability of APCs to activate T cells and drive effective immune responses, as used in vaccine and immunotherapy research[1][3][4][5][6]. However, "uptake enhancement" describes a function or therapeutic approach—not a unique molecule or canonical target—and does not refer to a singular receptor, enzyme, or protein.

Enhancement of antigen targeting to uptake receptors (e.g., Fcγ receptors, C-type lectin receptors); Increased uptake via phagocytosis, endocytosis, trogocytosis, or receptor-mediated internalization by APCs; Enhanced antigen presentation leading to T cell priming (via upregulated MHC, costimulatory molecules, and cytokines).
