Verified step by step guidance

Understand the role of MHC II proteins: MHC II proteins are crucial for the immune response, specifically in presenting antigens to certain immune cells.

Identify the types of cells that express MHC II proteins: MHC II proteins are primarily expressed on antigen-presenting cells (APCs) such as dendritic cells, macrophages, and B cells.

Differentiate between MHC I and MHC II proteins: MHC I proteins are found on all nucleated cells and present endogenous antigens to CD8+ T cells, while MHC II proteins present exogenous antigens to CD4+ T cells.

Clarify the type of antigens presented by MHC II: MHC II proteins present exogenous antigens, which are typically derived from extracellular pathogens that have been engulfed and processed by APCs.

Determine the correct statement: Based on the understanding of MHC II proteins, the true statement is that they are primarily expressed on antigen-presenting cells.
