The LAMP sequence causes an antigen, to which it is attached, to be taken up by the lysosomal subcellular compartment of the cell, an action that has been shown to increase presentation on MHC class II molecules, which in turn, can produce greater CD4+ T-cell responses against the antigen and a more potent and longer lasting overall immune response.
