  In this contribution we review recent ARPES results on the dressing of the
charge carriers in high-temperature superconductors. After an introduction into
the cuprates and their electronic structure, ARPES, the spectral function and
the self-energy function in the normal state and in the superconducting state
is discussed.. Finally results on the dressing of the charge carriers in the
system Bi2Sr2caCu2O7 at the nodal and the antinodal point are presented.
