Understand the Problem
The question is asking which statement regarding MHC class 2 expression is correct. It presents multiple-choice options that pertain to the characteristics and presence of MHC class 2 in different cell types.
Answer
They are primarily expressed on antigen-presenting cells.
The true statement about MHC class II molecules is that they are primarily expressed on antigen-presenting cells (APCs), such as dendritic cells, macrophages, and B-cells.
Answer for screen readers
The true statement about MHC class II molecules is that they are primarily expressed on antigen-presenting cells (APCs), such as dendritic cells, macrophages, and B-cells.
More Information
MHC class II molecules are crucial for the immune system as they present extracellular antigens to helper T-cells, triggering an immune response.
Tips
A common mistake is confusing MHC class I with MHC class II molecules. MHC class I molecules are present on almost all nucleated cells, while MHC class II molecules are primarily on antigen-presenting cells.
