Abstract

Peripheral blood mononuclear cells (MNCs) are accessible through blood collection and represent a useful source for investigations on disease mechanisms and treatment response. Aiming to build a reference proteome database, we generated three proteome data sets from MNCs using a combination of SDS-PAGE and nanoflow LC-MS. Experiments were performed in triplicates and 514 unique proteins were identified by at least two non-redundant peptides with 95% confidence for all replicates. Identified proteins are associated with a range of dermatologic, inflammatory and neurological conditions as well as molecular processes, such as free radical scavenging and cellular growth and proliferation. Mapping the MNC proteome provides a valuable resource for studies on disease pathogenesis and the identification of therapeutic targets.
