Guida verificata passo dopo passo1
Understand the role of MHC class II molecules: These molecules are crucial for the immune system, specifically in presenting antigens to T helper cells.
Identify the types of cells that express MHC class II molecules: These are primarily antigen-presenting cells (APCs), which include macrophages, dendritic cells, and B cells.
Recognize that basophils and neutrophils are not typically involved in antigen presentation and do not express MHC class II molecules.
Note that T helper cells interact with MHC class II molecules but do not express them themselves; they are the recipients of the antigen presentation.
Conclude that the correct answer involves macrophages and dendritic cells, as these are key APCs that express MHC class II molecules.
