Verified step by step guidance

Understand the role of CD8 coreceptors: CD8 is a glycoprotein that serves as a coreceptor on the surface of certain immune cells, playing a crucial role in the immune response.

Identify the function of Cytotoxic T cells: Cytotoxic T cells, also known as CD8+ T cells, are a subset of T cells that are primarily responsible for killing cancerous or infected cells.

Differentiate between T cell types: Helper T cells (CD4+ T cells) assist other cells in the immune response, while Cytotoxic T cells (CD8+ T cells) directly attack and destroy infected cells.

Recognize the expression of CD8: The CD8 coreceptor is specifically expressed on Cytotoxic T cells, which helps them recognize and bind to antigens presented by MHC class I molecules on infected cells.

Conclude the association: Based on the function and expression, the CD8 coreceptor is found on the surface of Cytotoxic T cells, distinguishing them from other immune cells like Helper T cells, Macrophages, and B cells.
