Coexistence of the topological state and a two-dimensional electron gas on the surface of Bi2Se3
The surface of a topological insulator plays host to an odd number of linearly-dispersing Dirac fermions, protected against back-scattering by time-reversal symmetry. Such characteristics make these materials ...

Open Accessp53 increases MHC class I expression by upregulating the endoplasmic reticulum aminopeptidase ERAP1
The p53 tumour suppressor has an important role in cancer cells. Here we show that p53 regulates expression of major histocompatibility complex I on the cell surface. We show that the tumour cell line HCT116, ...
