  We examine the flavor dependence of the nuclear modification factor $R_{AA}$
in the pQCD calculations at LHC energies. The computations are performed
accounting for radiative and collisional parton energy loss with running
coupling constant. Our results show that the recent LHC data on the $R_{AA}$
for charged hadrons, D-mesons and non-photonic electrons agree reasonably with
the pQCD picture of the parton energy loss with the dominating contribution
from the radiative mechanism.
