Verified step by step guidance

Understand the role of CD4 coreceptors in the immune system. CD4 is a glycoprotein found on the surface of immune cells and is crucial for the immune response.

Identify the types of T cells in the immune system: Helper T cells (Th cells) and Cytotoxic T cells (Tc cells). Helper T cells assist other cells in the immune response, while Cytotoxic T cells directly kill infected cells.

Recognize that CD4 coreceptors are primarily associated with Helper T cells. These receptors help the Helper T cells to recognize antigens presented by antigen-presenting cells (APCs) in conjunction with Major Histocompatibility Complex (MHC) class II molecules.

Differentiate between the roles of Helper T cells and other immune cells like B cells and Natural Killer cells. B cells are responsible for antibody production, while Natural Killer cells are involved in the destruction of virus-infected cells and tumors.

Conclude that the CD4 coreceptor is primarily found on Helper T cells, which play a pivotal role in orchestrating the immune response by activating other immune cells.
