antigen-presenting cell
a cell (e.g., macrophage) that processes antigen proteins and displays the short peptide fragments on its surface in conjunction with major histocompatibility (MHC) proteins, enabling recognition by T-cells.

ANTIGEN-PRESENTING CELL (APC)
The cell type that collects foreign material (antigen, see) and digests it into pieces that can be recognized by the immune system. The APC presents the antigen to the helper T cells<!-- (see) -->, the CD4+ T cells; this results in the initiation of expansion of an immune response targeted against the foreign material. APCs are B cells, macrophages, or dendritic cells (see entries for these terms).

antigen-presenting cell
B cell, macrophage, dendritic cell or other cell that ingests and processes foreign bodies such as viruses and displays the resulting antigen fragments on its surface to attract and activate the CD4+ T cells that respond specifically to that antigen. (See also dendritic cell; macrophage.)

Antigen-presenting cell
An antigen-presenting cell (APC) is a cell that displays foreign antigen complexed with MHC on its surface. T-cells may recognize this complex using their T-cell receptor (TCR).
