Integrated sequence and immunology filovirus database at Los Alamos.

Area of Science:

• Virology
• Computational Biology
• Immunology

Background:

• The 2013-15 Ebola outbreak highlighted the need for robust filovirus preparedness.
• Future outbreaks pose a significant threat, necessitating proactive strategies.
• Understanding natural viral diversity is crucial for developing effective vaccines and therapeutics.

Purpose of the Study:

• To update and enhance the Los Alamos Hemorrhagic Fever Viruses Database with filovirus sequence data.
• To provide integrated analyses of evolutionary patterns and immune response data.
• To identify conserved regions for T cell vaccine strategies.

Main Methods:

• Integrated all family Filoviridae sequences from GenBank.
• Performed baseline analysis of sequence data, immune response data, and metadata.
• Developed new computational tools with web-interfaces for user analysis.

Main Results:

• The database now includes comprehensive filovirus sequence and associated data.
• Integrated views reveal evolutionary patterns linked to geo-temporal data.
• Identified conserved proteomic regions potentially suitable for T cell vaccine development.

Conclusions:

• The enhanced database serves as a valuable resource for studying filovirus diversity.
• The findings support the development of broadly protective vaccines and therapeutics.
• Proactive analysis of viral diversity is essential for global health security against filoviruses.
