May 05, 2020 - NIH Research Project Grant (Parent R01 Clinical Trial Not Allowed). See NOFO PA-20-185 . National Institute of Allergy and Infectious Diseases ( NIAID ) The purpose of this Notice of Special Interest (NOSI) is to announce that the National Institute of Allergy and Infectious Diseases (NIAID) is encouraging applications to advance research activities relevant to systems modeling of infection and immunity.

Recipients will collaborate with the Center of Excellence (CoE) for Systems Modeling of Infection and Immunity across Biological Scales (U54 Clinical Trial Not Allowed) described in RFA-AI-23-077 . The CoE will coordinate the program, working with NIAID, and set up collaborations with recipients to participate in CoE activities.

Computational modeling can: (1) elucidate biological mechanisms of infection and/or transmission, (2) understand immune system regulation and responses to various triggers (commensal and pathogenic organisms, vaccines, environment, autoantigens), (3) characterize longitudinal trajectories of allergic or immune-mediated diseases from initiation through progression and/or resolution, including across the lifespan and effects of microbiome, (4) optimize public health control measures in response to epidemic threats, and (5) inform epidemic trajectories and develop therapeutic interventions.

Computational modeling projects are often siloed from other modeling projects, limiting their reuse, multiscale integration, transferability, and public health utility. There is a need to support a coordinated, collaborative network of computational modeling across the infectious and immune-mediated disease (IID) research community. Recipients will engage with the CoE to foster a collaborative modeling community supported by NIAID.

The overarching objectives of this NOSI are to: promote innovative modeling research to address key NIAID priority biomedical questions across biological scales (e.g., infection process of an organism, immunity and/or allergenic response, mechanistic models of vaccines and therapeutics, etc.). quickly mobilize modeling capabilities to meet newly emerging NIAID needs.

foster a collaborative community of new and existing investigators and establish educational opportunities for modeling of IID for students and junior investigators dedicated to modeling of IID. share models and modeling methods in a reproducible way aligned with the FAIR (Findable, Accessible, Interoperable, and Reusable) principles and the NIAID Data Ecosystem.

participate in activities with the Center of Excellence for Systems Modeling of Infection and Immunity across Biological Scales ( RFA-AI-23-077 ). Modeling projects may include, but are not limited to: molecular, cellular, organ, within-host, or between-host scales to represent precise mechanistic representations of processes related to IID. molecular determinants of infection and the immune response.

cellular factors of cell-entry, replication, and pathogenesis. organ-level factors, organism-level factors or exposures and overall health. environmental factors, such as zoonotic, climate, available medical care.

the public health system to represent processes of infection and immunity. within- or between-host pathogen dynamics, and/or the immune response. the effect of vaccines, therapeutics, or diagnostics.

multi-scale modeling of environmental and/or climatological data as it relates to IID (pathogen distribution, asthma, immunological complications, immune-mediated diseases, etc.). multi-scale models of pathogens that differentiate between within-host dynamics and between-host pathogen transmission to inform outcomes such as superspreader events. multi-scale computational models of respiratory virus infection and treatment.

multi-scale modeling of disease induction, progression, or remission of immune-mediated diseases within NIAID’s mission (e.g., allergy, asthma, autoimmunity, transplant rejection (cell, tissue, and/or organ)). multi-scale models to define immune-mediated sequalae, including autoimmune responses, following pathogenic infection, leveraging systems immunology or other comprehensive analyses.

multi-scale models that incorporate pathogen genomic heterogeneity (e.g., HIV or Staphylococcus aureus) and the immune response applied to within-host or between-host scales. multi-scale models that predict time to viral rebound in persons living with HIV who each stop conventional antiretroviral therapy (ART) or models that advance understanding of the persistent HIV reservoir.

A goal of this NOSI is to advance computational modeling approaches and technologies focused on infectious, allergic, and/or immune-mediated diseases across different biological scales. Projects will also have the opportunity to collaborate with the NIAID CoE for Systems Modeling of Infection and Immunity across Biological Scales.
