PAEP and infection: In addition, cellular receptors for gB, such as non-muscle myosin heavy chain IIA (NMHC-IIA), non-muscle myosin heavy chain IIB (NMHC-IIB), paired immunoglobulin-like receptor A (PILRa), or myelin-associated glycoprotein (MAG), can play a significant role in the infection of HSV-1.31, 32, 33, 34 The NMHC-IIA, NMHC-IIB, and MAG not only facilitate virion attachment but also actively promote the fusion process between plasma membranes, which is evident from their ability to significantly enhance cell–cell fusion when gB, gD, gH, and gL were co-expressed.31
