Although it had been known for several years that the TC is required for HCMV infection of fibroblasts, the cellular receptor for the TC was not identified until 2016, when Perez and colleagues demonstrated that the platelet-derived growth factor-α receptor (PDGFRα) is a cellular receptor for HCMV gH/gL/gO TC [68]. Here, PDGFRA is linked to cytomegalovirus infection.
