-Presents antigens to CD4 cells to activate the cell into a helper T cell MCH II - Presents antigens to CD8 cells to help activate cytotoxic T cells MHC I

The non-professional APCs express MHC class I molecules. T cells must be activated before they can divide and perform

These cells include B cells, macrophages, and dendritic cells. The pathway took place only after the engulfment of the antigen by the antigen-presenting cells. Inside the cell, the antigen carries a covering called an endosome. Helper T cells become activated through a multistep process, which begins with antigen-presenting cells, such as macrophages. These cells ingest an infectious agent or foreign particle, partially degrade it, and export fragments of it—i.e., antigens—to the cell surface. There the particles are presented in association with class II MHC molecules.

B cells. cytotoxic T cells. NK cells. An antigen-presenting cell or accessory cell is a cell that displays antigen complexed with major histocompatibility complexes on their surfaces; this process is known as antigen presentation. T cells may recognize these complexes using their T cell receptors.

When it comes to antigen-presenting cells, you'll have the chance to confirm your understanding by answering this quiz/worksheet's questions. These 2013-11-26 2016-07-10 Antigen presenting cell (APC) is specialized cell of our immune system that can recognize the foreign antigen or pathogenic substances and engulf them by endocytosis and break them down into small peptides and after this whole process they present these peptides (or the parts of the antigen) to other immune cells (mainly the T-lymphocytes) and induces immune response for these extracellular Antigen presentation is mediated by MHC class I molecules, and the class II molecules found on the surface of antigen-presenting cells (APCs) and certain other cells. MHC class I and class II molecules are similar in function: they deliver short peptides to the cell surface allowing these peptides to be recognised by CD8+ (cytotoxic) and CD4+ (helper) T cells, respectively. Because antigen presenting cells are MHC Class II positive they are responsible for the initiation of direct stimulation of naive CD4 + T cells and their potency can be attributed in part to the cell surface expression of costimulatory molecules that interact with receptor ligands on the surface of T cells.
