Abstract
Chikungunya virus (CHIKV) is a neglected tropical pathogen that causes fever and long-lasting severe arthralgia. Despite its high morbidity, there is still no licensed specific therapeutic option for it. This study proposes a multi-epitope subunit vaccine candidate for CHIKV, designed using computational methods. It was based on the E2 spike glycoprotein in CHIKV, from which T- and B-cell epitopes were predicted and then refined. The pan HLA DR-binding epitope (PADRE) was added to this refined construct, then simulated compared with the native protein, where it was predicted to elicit more than twice the number of antibody titers. Thus, this construct is potentially effective against CHIKV, which further experimentation using live models would be able to verify. This study also demonstrates the feasibility of using rational tools in the future to further optimize vaccine design.
期刊介绍：
The Society publishes the Journal – Tropical Biomedicine, 4 issues yearly. It was first started in 1984. The journal is now abstracted / indexed by Medline, ISI Thompson, CAB International, Zoological Abstracts, SCOPUS. It is available free on the MSPTM website. Members may submit articles on Parasitology, Tropical Medicine and other related subjects for publication in the journal subject to scrutiny by referees. There is a charge of US$200 per manuscript. However, charges will be waived if the first author or corresponding author are members of MSPTM of at least three (3) years'' standing.
