Background: Cytomegalovirus gH Pentamer Complex

Human cytomegalovirus, also called HCMV or human herpesvirus 5, is a double-stranded DNA, enveloped virus of 230-250 kilobases (kb) that is a member of the Herpesviridae family and the subfamily Betaherpesvirinae (1,2). Other herpesviruses, which share the characteristic of lifelong latency following primary infection, include herpes simplex virus types 1 (HSV-1) and 2 (HSV-2), varicella zoster virus (VSV), and Epstein-Barr virus (EBV) (1). Cytomegalovirus entry into cells is mediated by a trimeric complex of glycoproteins gH, gL, and gO and a pentamer made of proteins gH, gL, UL128, UL130, and UL131A (1,3). The trimer binds PDGFRalpha for entry into fibroblasts while the pentamer binds neuropilin-2 for entry into endothelial and epithelial cells (1,4). Additionally, the fusion protein glycoprotein B (gB) plays a pivotal role for cytomegalovirus entry into the host cell membrane (1,3).

Cytomegalovirus is a common virus, infecting ~60% of adults in developed countries and over 90% in developing countries, as indicated by presence of specific IgG antibodies (2-4). Although a majority of people infected remain asymptomatic, immunocompromised people, organ transplant recipients, and fetuses and newborns are more susceptible to HCMV-associated diseases (1-4). Annually, up to 2% of newborns are born with HCMV, making it the most common congenital infection (2-4). Cytomegalovirus is known to cause sensorineural hearing loss (SNHL), mental retardation, chorioretinitis, skin lesions, as well as end organ disease (3,5). There are a few CMV therapeutics approved by FDA including valganciclovir and letermovir; however, despite some benefits, there is the need for new antivirals and combination therapies (5). Potential new treatment options include monoclonal antibodies and sirtuins (5).
