Current perspectives on alphavirus encapsidation, assembly and budding [PDF]

Frontiers in Cellular and Infection Microbiology
Alphaviruses are an escalating global concern due to their considerable clinical impact and expanding geographic distribution. Transmitted primarily through the bites of infected mosquitoes, alphaviruses cause a wide spectrum of arthritogenic and ...

Arthritogenic Alphavirus Capsid Protein

Life, 2021
In the past two decades Old World and arthritogenic alphavirus have been responsible for epidemics of polyarthritis, causing high morbidity and becoming a major public health concern. The multifunctional arthritogenic alphavirus capsid protein is crucial

Seroprevalence of alphavirus antibodies in a cross-sectional study in southwestern Tanzania suggests endemic circulation of chikungunya. [PDF]

PLoS Neglected Tropical Diseases, 2014
BACKGROUND: To date, Alphavirus infections and their most prominent member, chikungunya fever, a viral disease which first became apparent in Tanzania in 1953, have been very little investigated in regions without epidemic occurrence.

Vaccination with DNA plasmids expressing Gn coupled to C3d or alphavirus replicons expressing gn protects mice against Rift Valley fever virus. [PDF]

PLoS Neglected Tropical Diseases, 2010
Rift Valley fever (RVF) is an arthropod-borne viral zoonosis. Rift Valley fever virus (RVFV) is an important biological threat with the potential to spread to new susceptible areas.

Autoantibodies and Molecular Mimicry in Alphavirus Chronic Arthritis: A Systematic Review [PDF]

Pathogens
Chronic arthritis following arthritogenic alphavirus infections presents symptoms resembling autoimmune rheumatic diseases, raising questions about the underlying mechanisms, including molecular mimicry and autoantibody production. This systematic review

Alphavirus Infection: Host Cell Shut-Off and Inhibition of Antiviral Responses

Viruses, 2016
Alphaviruses cause debilitating disease in humans and animals and are transmitted by blood-feeding arthropods, typically mosquitoes. With a traditional focus on two models, Sindbis virus and Semliki Forest virus, alphavirus research has significantly ...

The Putative Roles and Functions of Indel, Repetition and Duplication Events in Alphavirus Non-Structural Protein 3 Hypervariable Domain (nsP3 HVD) in Evolution, Viability and Re-Emergence

Viruses, 2021
Alphavirus non-structural proteins 1–4 (nsP1, nsP2, nsP3, and nsP4) are known to be crucial for alphavirus RNA replication and translation. To date, nsP3 has been demonstrated to mediate many virus–host protein–protein interactions in several fundamental

Alphaviruses in Immunotherapy and Anticancer Therapy

Biomedicines, 2022
Alphaviruses have been engineered as expression vectors for vaccine development and gene therapy. Due to the feature of RNA self-replication, alphaviruses can provide exceptional direct cytoplasmic expression of transgenes based on the delivery of ...

Expression of Alphavirus Nonstructural Protein 2 (nsP2) in Mosquito Cells Inhibits Viral RNA Replication in Both a Protease Activity-Dependent and -Independent Manner

Viruses, 2022
Alphaviruses are positive-strand RNA viruses, mostly being mosquito-transmitted. Cells infected by an alphavirus become resistant to superinfection due to a block that occurs at the level of RNA replication. Alphavirus replication proteins, called nsP1-4,
