  We review some recent results about the computation of mixed QCD-QED
corrections beyond the leading order in perturbation theory. We start by
considering the effects induced in the Altarelli-Parisi equations and the
partonic distributions. In particular, we describe the computation of one-loop
mixed QCD-QED and two-loop QED terms in the splitting kernels, which are
relevant to account for the presence of photon distributions. In the last part,
we briefly talk about the implementation of these corrections in the context of
the $q_T$-subtraction/resummation formalism.
