Glycoprotein D (gD) of herpes simplex virus (HSV) is essential for virus entry. Both glycoproteins inhibited entry of HSV-1 and HSV-2 without affecting virus adsorption. The focus of this study, gH, is expressed as a heterodimer with gL (gH-gL). A. Intrinsic radiolabeling of group E mutant infections with [14C]glucosamine revealed that normal glycoproteins were produced at 34 degrees C but none were synthesized at 39 degrees C. Two insertions into a conserved region of gL abrogated the binding of gL to gH and prevented gH expression on the cell surface. Neutralization tests and radioiodination experiments revealed that gF-2 is exposed on the surfaces of virions and that the 75K form of gF-2 is exposed on cell surfaces.

In wild-type virus-infected cells, the surface levels of EGFR were also decreased in the absence of EGF stimulation. Stimulation by EGF enhanced the decrease in surface EGFR. We conclude that ICP0 encodes SH3 domain binding sites that function to down-regulate signaling pathways associated with receptor tyrosine kinases. In particular, CTL have been shown to be crucial for control of both productive and latent virus infections, and this is mirrored in the plethora of mechanisms which members of the Herpesviridae family have adopted to evade major histocompatibility complex (MHC) class I-mediated immune responses (39).

The SalI-L fragment from human herpesvirus 6A (HHV-6A) encodes a protein DR7 that has been reported to produce fibrosarcomas when injected into nude mice, to transform NIH3T3 cells, and to interact with and inhibit the function of p53. Viral DNA synthesis reached a maximum between 24 to 36 hr postinfection, preceded by a transient stimulation of host cell DNA synthesis. Ribonuclease protection analyses revealed that all 17 mutants synthesize the IE mRNA in RK-13 cells, whereas those that failed to replicate on non-complementing RK-13 cells displayed a defect in the transcription of either an important early gene (EICP0) and/or an essential late gene (glycoprotein D). Moreover, this study is the first to demonstrate that gG expressed at the surface of FeHV-1-infected cells can also bind chemokines. Variable levels of neutralization of HMVEC-d and HFF infection were observed with antibodies against alphaVbeta3 and alphaVbeta5 integrins. Surface labelling and trypsin digestion protection experiments showed that the BHV-1 UL49.5h protein was present on the surface of infected cells and on the surface of mature virions. Proteins immunoprecipitated by this antibody from virus-infected cells ran at 36 and 43 kDa in reducing sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and 43 and 48 kDa in nonreducing SDS-PAGE.

In wild-type virus-infected cells, the surface levels of EGFR were also decreased in the absence of EGF stimulation. Stimulation by EGF enhanced the decrease in surface EGFR. There, they engage a single heterodimeric receptor, IFNAR, and trigger activation of a signaling pathway that generates a plethora of proteins with broad-spectrum antiviral activities. Liang, B.
