Research Abstract

We found a novel mechanism of down-regulation of transferring receptor. We characterized an intracellular logistics of BST-2/Tetherin, which is a host restriction factor of retrovirus. We found that Vpu, an accessory protein of HIV-1, counteracts a role of BST-2/Tetherin. We further analyzed the mechanisms of two novel whitening reagents in melanocytes.
