MHC class I assembly and presentation

This short video describes how MHC class I molecules are assembled and delivered on the surface of cells to present petides to T cells. This allows T-cells to determine whether the cell is iinfected with a virus by allowing a T cell to essentially look inside the cell. The immune sytem, T cells and MHC class I molecules play a vital role in protecting our bodies from infection. Video by Diego Accorsi.
