The precision determination of parton distributions is an essential ingredient for LHC phenomenology. In this talk we review recent progress in the NNPDF determnation of parton distributions. We estimate theoretical uncertainties in LHC observables arising from heavy quark mass effects. We show how to use Bayesian inference to determine the impact of new data into PDFs without the need of refitting. Finally, we discuss the impact of PDFs on the interpretation of the first LHC measurements and exclusion limits, and examine how LHC data can be used to further constrain PDFs in a new kinematical regime.
