Monoclonal antibody targeting chikungunya virus envelope 1 protein inhibits virus release

Virology. 2014 Sep:464-465:111-117. doi: 10.1016/j.virol.2014.05.038. Epub 2014 Jul 24.

Abstract

Chikungunya virus (CHIKV) causes an acute clinical illness characterized by sudden high fever, intense joint pain, and skin rash. Recent outbreaks of chikungunya disease in Africa and Asia are a major public health concern; however, there is currently no effective licensed vaccine or specific treatment. This study reported the development of a mouse monoclonal antibody (MAb), CK47, which recognizes domain III within the viral envelope 1 protein and inhibited the viral release process, thereby preventing the production of progeny virus. The MAb had no effect on virus entry and replication processes. Thus, CK47 may be a useful tool for studying the mechanisms underlying CHIKV release and may show potential as a therapeutic agent.

Keywords: Chikungunya virus; Monoclonal antibody; Post-entry inhibitory step.
