Area of Science:

  • Molecular biology
  • Systems biology
  • Computational biology

Background:

  • COVID-19 outcomes vary due to complex host-pathogen interactions at molecular and cellular levels.
  • Understanding these interactions is crucial for disease management and therapeutic development.

Purpose of the Study:

  • To propose a systematic framework for understanding molecular host-pathogen interactions (HPIs).
  • To develop a computational approach for analyzing HPIs and their relation to disease outcomes.
  • To demonstrate the framework's application in COVID-19 research for drug/vaccine design.

Main Methods:

  • Formulation of four foundational HPI postulates.
  • Development of the HPI Postulate and Ontology (HPIPO) framework using interoperable ontologies.
  • Application of HPIPO and CIDO to COVID-19 data, including prediction of host-coronavirus protein-protein interactions (PPIs).

Main Results:

  • The HPI postulates provide a basis for understanding HPI dynamics, roles, and critical checkpoints.
  • The HPIPO framework enables AI-ready data standardization, sharing, and analysis of HPIs.
  • A novel approach for designing drug/vaccine cocktails targeting critical host-coronavirus interaction checkpoints was demonstrated for COVID-19.

Conclusions:

  • The proposed postulates and HPIPO framework offer a systematic approach to studying complex host-pathogen interactions.
  • This framework facilitates AI-driven analysis and supports the rational design of therapeutics for infectious diseases like COVID-19.
  • Further exploration of host-pathogen PPIs using this framework can advance our understanding and treatment strategies.
