Verified step by step guidance

Understand the role of CD markers: CD markers are molecules on the surface of immune cells that help differentiate between different types of cells. They are crucial for identifying and classifying immune cells.

Identify the types of effector T cells: There are two main types of effector T cells - Cytotoxic T cells and Helper T cells. Each type has distinct functions and markers.

Learn about Cytotoxic T cells: Cytotoxic T cells are responsible for killing infected cells and cancer cells. They are characterized by the presence of CD8 markers on their surface.

Learn about Helper T cells: Helper T cells assist other cells in the immune response, such as activating B cells and Cytotoxic T cells. They are characterized by the presence of CD4 markers on their surface.

Match the markers to the correct T cell type: Cytotoxic T cells have CD8 markers, while Helper T cells have CD4 markers. This differentiation is crucial for understanding their roles in the immune system.
