Eukaryotic cells respond to extracellular stimuli, such as viruses, by recruiting signal transduction pathways, many of which are mediated through activation of distinct mitogen-activated protein kinase (MAPK) cascades and activation of transductional regulation factors. The best characterized of this pathway are the extracellular signal regulated kinase (ERK), the c-Jun N-terminal kinase/stress activated protein kinase (JNK/SAPK), and the p38 MAPK cascade. Herpes simplex virus type 1 (HSV-1) encodes at least 11 envelope glycoproteins, which alone or in concert play different roles in viral adsorption, entry, cell-to-cell spread, and immune evasion. Of these proteins, three are designated glycoprotein B (gB), glycoprotein D (gD), and the gH/gL heterodimer, are clearly involved in attachment and entry, and therefore possible candidates in inducing early cellular activation.Nevertheless, the precise role of each glycoprotein and the cellular factor involved remain elusive. The signal transduction pathways involved, and the outcome of cellular activation on viral entry or postentry events, are still to be elucidated. To better understand the role of signal transduction pathways and phosphorylation events in HSV-1 entry, synthetic peptides modeled on HSV-1 gH were synthesized and tested for MEK1-MEK2/MAPK cascade activation. Our results show a major involvement of the JNK pathway in the intracellular signal transmission after stimulation with gH HSV-1 peptides.

D020935 MAP Kinase Signaling System An intracellular signaling system involving the mitogen-activated protein kinase cascades (three-membered protein kinase cascades). Various upstream activators, which act in response to extracellular stimuli, trigger the cascades by activating the first member of a cascade, MAP KINASE KINASE KINASES; (MAPKKKs). Activated MAPKKKs phosphorylate MITOGEN-ACTIVATED PROTEIN KINASE KINASES which in turn phosphorylate the MITOGEN-ACTIVATED PROTEIN KINASES; (MAPKs). The MAPKs then act on various downstream targets to affect gene expression. In mammals, there are several distinct MAP kinase pathways including the ERK (extracellular signal-regulated kinase) pathway, the SAPK/JNK (stress-activated protein kinase/c-jun kinase) pathway, and the p38 kinase pathway. There is some sharing of components among the pathways depending on which stimulus originates activation of the cascade.
