· Author information: (1)Department of Molecular and Cell Biology, Life Sciences Addition, University of California, Berkeley, CA 94720, USA. Memory T cells circulate through lymph nodes where they are poised to respond rapidly upon re-exposure to a pathogen; however, the dynamics of memory T cell, antigen-presenting cell, and pathogen interactions during recall responses are largely unknown.

In the present study, we show that human neutrophils acquire an antigen-presenting cell (APC) phenotype following RBC phagocytosis. Subsequent to RBC phagocytosis, neutrophils expressed major histocompatibility complex class II (MHC-II) and costimulatory molecules such as CD40 and CD80.

Macrophages are antigen presenting cells that actively phagocytose large particles. Therefore, they play an important role in presenting antigens derived from phagocytosed infectious organisms such as bacteria and parasites. In the effector phase of cell-mediated

An antigen-presenting cell (APC) or accessory cell is a cell that displays antigen complexed with major histocompatibility complexes (MHCs) on their surfaces; this process is known as antigen presentation.T cells may recognize these complexes using their T cell receptors (TCRs). (TCRs).
Antigen Presenting Cell (APC)
APC binds antigens, internalizes, processes and expresses them on their surface in conjunction with class II type molecules (one of the two type of molecules coded for by the MHC genes). Cite this entry as: (2008) Antigen Presenting Cell (APC). In
Antigen-Presenting Cell (APC)
The APC must also express the appropriate costimulatory ligands to promote T cell activation. Whereas all nucleated cells generally express MHC Class I molecules and are potential APCs for CD8 + T cells, only specialized “professional” APCs express MHC class II molecules and can present antigen …
Antigen-presenting cell Last updated December 22, 2020 Antigen presentation stimulates immature T cells to become either mature “cytotoxic” CD8+ cells or mature “helper” CD4+ cells.An antigen-presenting cell (APC) or accessory cell is a cell that displays antigen complexed with major histocompatibility complexes (MHCs) on their surfaces; this process is known as antigen presentation.
n any of various cells (as a macrophage or a B cell) that take up and process an antigen into a form that when displayed at the cell surface in combination with a molecule of the major histocompatibility complex is recognized by and serves to…

The APCs are then cultured in a laboratory, where they are grown in the
antigen-presenting cells: cells that process protein antigens into peptides and present them on their surface in a form that can be recognized by lymphocytes. APCs include Langerhans cells, dendritic cells, macrophages, B cells, and, in humans, activated T cells. Synonym(s): accessory cell
