The National Institutes of Health (NIH) and the National Institute of Allergy and Infectious Diseases (NIAID) intend to publish a Funding Opportunity Announcement (FOA) for applications pertaining to the Molecular Dynamics (MD) of HIV. The purpose of this Funding Opportunity Announcement (FOA) is to support computational dynamic modeling of molecular complexes regulating the HIV life cycle, immune responses, and therapeutic interventions in HIV/AIDS using existing and new HIV and HIV/host cell structural datasets. This Notice is being issued to allow potential applicants more time to consider the requirements of this program and to develop responsive projects.
Background
Molecular Dynamics (MD) simulates the movement of atoms and molecules over time, providing testable models of complex molecular behavior. MD can capture the movement of proteins and other biomolecules in full atomic detail at femtosecond time scales to simulate a variety of biomolecular functions, including ligand or drug binding, protein conformational dynamics, and complex cellular processes like membrane fusion and scission. Multi-scale dynamic modeling extends the scale of simulations to include multi-component complexes or even whole cellular environments. Addition of the dimension of time to the three-dimensional structures already studied by structural biologists can facilitate novel insights into their function. The goal of the modeling is to provide detailed, testable “4D” molecular models depicting dynamic biologic processes. Over the past decade, a large number of high-resolution structures of key HIV and HIV/host cell molecular complexes have been solved. With this initiative, NIAID intends to leverage those accumulating datasets to better understand the dynamic interactions that exist throughout the HIV viral life cycle.
Research Objectives
This initiative will support integrated structural, computational, and functional approaches to study the dynamics of key molecular processes in the HIV life cycle. Applications should address a crucial component of the HIV life cycle, immunological response, or therapeutic intervention that is amenable to structural determination and dynamic modeling. Projects may not be based on purely theoretical modeling of sequence data, but instead should be centered around datasets generated by appropriate atomic or molecular scale approaches such as NMR, electron microscopy or optical techniques. Research projects should include iterative biologic testing and refinement of the computational models to generate an accurate and rigorous model system. Approaches affording insight at all cellular scales, from atomistic to whole-cell resolutions, are encouraged. Development of new technological innovation in modeling approaches and computational processes is highly desired, as are projects that leverage machine learning / artificial intelligence to facilitate analyses. Research teams should include computational modelers along with structural biologists, virologists, immunologists or other appropriate expertise to validate model systems. Applications that propose vertebrate animal research and/or clinical research are allowed.
Examples of research foci of interest include but are not limited to:
