Pathogenesis and ImmunityExpression of the Pseudorabies Virus gB Glycoprotein Triggers NK Cell Cytotoxicity and Increases Binding of the Activating NK Cell Receptor PILRβNatural killer (NK) cells display a prominent cytolytic activity against virus-infected cells and are indispensable in the innate antiviral response, particularly against herpesviruses. Despite their importance in the control of alphaherpesvirus infections, relatively little is known about the mechanisms that trigger NK cell cytotoxicity against alphaherpesvirus-infected cells. Here, using the porcine alphaherpesvirus pseudorabies virus...
Pathogenesis and ImmunityThe Carboxyl Terminus of Tegument Protein pUL21 Contributes to Pseudorabies Virus NeuroinvasionHerpesviruses are a group of DNA viruses that infect both humans and animals. Alphaherpesviruses are distinguished by their ability to establish latent infection in peripheral neurons. After entering neurons, the herpesvirus capsid interacts with cellular motor proteins and undergoes retrograde transport on axon microtubules. This elaborate process is vital to the herpesvirus lifecycle, but the underlying mechanism remains poorly...
Virus-Cell InteractionsRole of Sphingomyelin in Alphaherpesvirus EntryBovine herpesvirus 1 (BoHV-1) is an ubiquitous pathogen affecting cattle populations worldwide. Infection can result in complicated, polymicrobial infections due to the immunosuppressive properties of the virus. Available vaccines limit disease severity and spread but do not prevent infection. The financial and animal welfare ramifications of BoHV-1 are significant. In order to develop more effective prevention and treatment regimens, a...
Virus-Cell InteractionsLow-pH Endocytic Entry of the Porcine Alphaherpesvirus Pseudorabies VirusPRV is a pathogen of great economic and animal welfare importance in many parts of the world. PRV causes neurological, respiratory, and reproductive disorders, often resulting in mortality of young and immunocompromised animals. Mortality, decreased production, and trade restrictions result in significant financial losses for the agricultural industry. Understanding the molecular mechanisms utilized by PRV to enter host cells is an...
Pathogenesis and ImmunityVirulent Pseudorabies Virus Infection Induces a Specific and Lethal Systemic Inflammatory Response in MicePseudorabies virus (PRV) is an alphaherpesvirus related to human pathogens such as herpes simplex virus 1 and varicella-zoster virus (VZV). The natural host of PRV is the swine, but it can infect most mammals. In susceptible animals other than pigs, PRV infection always causes a characteristic lethal pruritus known as the “mad itch.” The role of the immune response in the clinical outcome of PRV infection is still poorly understood....
- Structure and AssemblyDissecting the Herpesvirus Architecture by Targeted Proteolysis
Neuroinvasive alphaherpesviruses produce diseases of clinical and economic significance in humans and veterinary animals but are predominantly associated with less serious recurrent disease. Like all viruses, herpesviruses assemble a metastable particle that selectively dismantles during initial infection. This process is made more complex by the presence of a tegument layer that resides between the capsid surface and envelope....
