The immune system's response if the cell does not have the MHC Class I protein is by activating natural killer cells that will attach directly to foreign cells in the body.

What is the role of MHC in the immune response?

Two types of MHC molecules characterize the body's cells, namely MHC class I found in all nucleated cells in almost every cell of the body. Meanwhile, MHC class II is limited to a few specialized cell types including macrophages, B cells, activated T cells, and cells that make up the interior of the thymus.
