Question

Which Professional Antigen Presenting Cell (Professional - APC) is strong enough to activate a CD8 T cell from a naive state?

Answer 1

Dendritic cells are the professional antigen presenting cells that are strong enough to activate CD8 T cells from a naive state.

Step-by-step explanation:

The professional antigen presenting cell (APC) that is strong enough to activate a CD8 T cell from a naive state is a dendritic cell (DC). Dendritic cells are highly efficient at presenting antigens and activating CD8 T cells. They capture and process antigens, then display them on their surface using MHC class I molecules. When a naive CD8 T cell encounters an antigen presented by a dendritic cell, it becomes activated and can differentiate into cytotoxic T lymphocytes (CTLs) that can kill infected cells.
