Which cell line will the antigen presenting cell present the infectious agent to?

Professional antigen-presenting cells, including macrophages, B cells and dendritic cells, present foreign antigens to helper T cells, while virus-infected cells (or cancer cells) can present antigens originating inside the cell to cytotoxic T cells.

What is the purpose of an antigen presenting cell?

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.

What role does an antigen presenting cell play in the activation of a T cell?

Antigen-presenting cells display three types of protein molecules on their surface that have a role in activating a T cell to become an effector cell: (1) MHC proteins, which present foreign antigen to the T cell receptor, (2) costimulatory proteins, which bind to complementary receptors on the T cell surface, and (3) …

How does the antigen presenting cell work when there is an infection in our body?

An antigen-presenting cell (APC) is an immune cell that detects, engulfs, and informs the adaptive immune response about an infection. When a pathogen is detected, these APCs will phagocytose the pathogen and digest it to form many different fragments of the antigen.

How is antigen presentation done?

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. There is also so called cross-presentation in which exogenous antigens can be presented by MHC class I molecules.

What is meant by antigen presentation and how do antigen-presenting cells present antigens?

Antigen-presenting cells (APC) are cells that can process a protein antigen, break it into peptides, and present it in conjunction with class II MHC molecules on the cell surface where it may interact with appropriate T cell receptors.

What exactly does an antigen-presenting cell present quizlet?

Terms in this set (6) Cells such as B cells, macrophages, and dendritic cells that can present exogenous antigens to naive or memory T cells, activating them. The innate immune system activates and are engulfed. The pathogens are presented on the MHC Class 2 on the membrane.
