Chikungunya Virus (CHIKV)
Viral Structure, Key Antigen Targets and Research Applications
Overview
Chikungunya virus (CHIKV) is an enveloped, mosquito-borne virus belonging to the genus Alphavirus in the family Togaviridae. It is primarily transmitted by Aedes aegypti and Aedes albopictus mosquitoes and causes chikungunya fever.
CHIKV infection is commonly associated with fever, rash, and pronounced joint and muscle pain. Research on CHIKV focuses on viral entry and replication, host-virus interactions, immune responses, antigenicity, and antibody-mediated neutralization.
The CHIKV genome is approximately 11.8 kb and contains two major open reading frames. The 5' ORF encodes the four non-structural proteins nsP1-nsP4, while the 3' ORF encodes the structural proteins Capsid, E3, E2, 6K, and E1.
CHIKV Structure
CHIKV is an enveloped virus approximately 60-70 nm in diameter. Its positive-sense single-stranded RNA genome is enclosed within a capsid and surrounded by a lipid envelope. The viral surface contains spike complexes formed by the E1 and E2 glycoproteins. Together, these proteins provide a framework for studying different stages of the CHIKV life cycle, from viral entry and membrane fusion to RNA replication and virion assembly.
