Abstract :
[en] Cell surface protein study has shown growing interest in the past few years in the medical and pharmaceutical community. Indeed, due to their easy accessibility, they represent the largest category of drug targets today. Nevertheless, their analysis and characterization remain challenging due to their poor solubility, cleavability, and abundance, as well as their higher aggregability and glycosylation. This review presents current and innovative strategies for cell surface protein extraction, such as innovative biotinylation-based strategies, cell sorting-based strategies, nanodiscs strategies, hydrazide-chemistry-based strategies or enzyme-based and spatially restricted strategies. It also presents analytical workflows innovations applicable to cell surface protein analysis such as using liquid chromatography (i.e. nanoflow micropillar array columns - PAC), and/or capillary electrophoresis coupled with innovative mass spectrometry data acquisition modes. Finally, this review gives some illustrations of the interest of surfacome studies in the field of cancer research.
