plural antigen-presenting cells : any of various cells (such as a dendritic cell, macrophage, or B cell) that take up and process an antigen into a peptide fragment which when displayed at the cell surface in combination with a molecule of the major histocompatibility complex is recognized by...
Antigen-presenting cells (APCs) are a heterogeneous group of immune cells that mediate the cellular immune response by processing and presenting antigens for recognition by certain lymphocytes such as T cells. Classical APCs include dendritic cells, macrophages, Langerhans cells and B cells. ...
