Purpose and Research Objectives
The purpose of this Funding Opportunity Announcement (FOA) is to invite applications to support innovative clinical and preclinical/non-clinical research to determine the potential of myeloid-derived suppressor cells (MDSCs) as a target for host-directed therapeutics for tuberculosis (TB) in the context of HIV co-infection, and to better understand the role of host-induced immunosuppression in the progression of TB disease.
Mycobacterium tuberculosis (Mtb), the causative agent of TB, is now the leading cause of death due to an infectious disease worldwide. Currently available antimicrobial therapy requires lengthy treatment times and is complicated by intolerance and drug interactions. The incidence of multi-drug resistant TB (MDR-TB) continues to increase and now causes 5% of new TB cases with only a 54% treatment success rate. Thus, an urgent need to develop new therapeutic strategies is evident. To address this situation, development of adjunctive host-directed therapies (HDTs) have become a focal point in TB research for multiple reasons. HDT may enhance both immune function and improve the penetration and effectiveness of antimicrobial therapy. Mtb is not directly targeted and HDTs should be effective for therapy of Mtb strains with any antimicrobial resistance patterns and the risk of antimicrobial resistance is significantly diminished. HDTs may also reduce inflammatory lung damage, decreasing loss of pulmonary function caused by TB. Rational identification of targets is needed to optimize therapeutic opportunities for decreasing treatment duration and/or improving lung function.
Discovery of Mtb’s mechanisms to inhibit immunity has become an active area of research. Mtb utilizes several cell wall and cytosolic molecules to inhibit phagosome maturation and function, block antigen processing/presentation, and inhibit T cell activation. The role of host immunomodulatory mechanisms induced during Mtb infection is far less understood. Several types of suppressor immune cells are activated to dampen chronic immune activation and protect against excess inflammatory damage and promote healing. Both regulatory T cells (Tregs) and myeloid-derived suppressor cells (MDSCs) play a critical role in the immunoregulatory process during TB infection. MDSCs are a transient immature myeloid cell population derived from common myeloid progenitor cells during infection or cancer progression. While discovered over a decade ago, a method for accurate phenotypic identification by cell markers of MDSCs has proven difficult. Two MDSC types have been characterized: polymorphonuclear MDSCs (PMN-MDSCs), a granulocytic type similar to neutrophils and monocytic MDSCs (M-MDSCs), a type similar to monocytes. MDSCs utilize a variety of mechanisms, including direct cell-cell interactions and soluble factors, to suppress some immune functions.
MDSCs have been extensively studied in cancer biology. In clinical studies of several types of cancers accumulation of MDSCs in peripheral blood was associated with tumor development and progression. MDSCs block T cell activation during tumor progression by recruiting Tregs, removing essential amino acids (e.g. cysteine, arginine) from the microenvironment, inducing reactive oxygen species, and direct interaction through inducing higher expression of PD-1/PDL-1. MDSCs are also important contributors to tumor metastasis. Pro-inflammatory mediators, including cytokines and DAMPs (e.g. HMGB1, S100A8/9), within the tumor microenvironment recruit MDSCs that then produce proangiogenic and hepatocyte growth factors needed for metastasis. Higher numbers of MDSCs have also been linked to negative prognosis during cancer treatment.
While not as thoroughly studied as in cancer, some studies have shown that MDSCs play a significant role during the immune response to infectious diseases. Several viral, bacterial, and parasitic infections have been shown to induce MDSC development. As with cancer, inflammation (through cytokines, DAMPs, and microbial produced TLR ligands) is a primary driver of MDSC generation by infectious diseases. Chronic infections, including Helicobacter pylori and Hepatitis C, persist through MDSC-triggered T cell suppression.
For Mtb infection, the limited data suggest that MDSCs also play an important role. MDSCs accumulate in the blood and pleural fluid of active TB patients, and their circulating numbers decrease after successful chemotherapy. Ablation of MDSCs through all-trans retinoic acid reduced Mtb loads and TB pathology in a mouse model. Evidence suggests that MDSCs phagocytose but do not kill Mtb and may contribute to bacterial persistence by both harboring bacilli and interfering with the effectiveness of macrophage responses.
The cancer field is currently exploring the potential of MDSCs as immunotherapeutic targets. Agents act by targeting MDSC development, inducing differentiation into more mature monocytes and/or blocking immunosuppressive mechanisms. Further research is needed to define the potential of MDSCs as an HDT target for TB.
Specific Areas of Research Interest
This FOA will support early stage hypothesis-based clinical and preclinical/non-clinical research studies focused on: 1) the role of MDSCs in TB disease infection, latency, reactivation/progression, treatment response, and relapse; 2) assessing MDSC induction, development, regulation, and suppressive mechanisms during Mtb infection/disease and identification of MDSC-related HDT targets; and 3) evaluating new/repurposed therapeutic agents targeting MDSCs for improving TB treatment outcomes.

Awardees must comply with any funding restrictions described in Section IV.5. Funding Restrictions. Selection of an application for award is not an authorization to begin performance. Any costs incurred before receipt of the NoA are at the recipient's risk. These costs may be reimbursed only to the extent considered allowable pre-award costs.
Any application awarded in response to this FOA will be subject to terms and conditions found on the Award Conditions and Information for NIH Grants website. This includes any recent legislation and policy applicable to awards that is highlighted on this website.
Institutional Review Board or Independent Ethics Committee Approval: Grantee institutions must ensure that protocols are reviewed by their IRB or IEC. To help ensure the safety of participants enrolled in NIH-funded studies, the awardee must provide NIH copies of documents related to all major changes in the status of ongoing protocols.
Recipients of federal financial assistance (FFA) from HHS must administer their programs in compliance with federal civil rights law. This means that recipients of HHS funds must ensure equal access to their programs without regard to a person’s race, color, national origin, disability, age and, in some circumstances, sex and religion. This includes ensuring your programs are accessible to persons with limited English proficiency. HHS recognizes that research projects are often limited in scope for many reasons that are nondiscriminatory, such as the principal investigator’s scientific interest, funding limitations, recruitment requirements, and other considerations. Thus, criteria in research protocols that target or exclude certain populations are warranted where nondiscriminatory justifications establish that such criteria are appropriate with respect to the health or safety of the subjects, the scientific study design, or the purpose of the research.
In accordance with the statutory provisions contained in Section 872 of the Duncan Hunter National Defense Authorization Act of Fiscal Year 2009 (Public Law 110-417), NIH awards will be subject to the Federal Awardee Performance and Integrity Information System (FAPIIS) requirements. FAPIIS requires Federal award making officials to review and consider information about an applicant in the designated integrity and performance system (currently FAPIIS) prior to making an award. An applicant, at its option, may review information in the designated integrity and performance systems accessible through FAPIIS and comment on any information about itself that a Federal agency previously entered and is currently in FAPIIS. The Federal awarding agency will consider any comments by the applicant, in addition to other information in FAPIIS, in making a judgement about the applicant’s integrity, business ethics, and record of performance under Federal awards when completing the review of risk posed by applicants as described in 45 CFR Part 75.205 “Federal awarding agency review of risk posed by applicants.” This provision will apply to all NIH grants and cooperative agreements except fellowships.
For additional guidance regarding how the provisions apply to NIH grant programs, please contact the Scientific/Research Contact that is identified in Section VII under Agency Contacts of this FOA. HHS provides general guidance to recipients of FFA on meeting their legal obligation to take reasonable steps to provide meaningful access to their programs by persons with limited English proficiency. Please see https://www.hhs.gov/civil-rights/for-individuals/special-topics/limited-english-proficiency/index.html. The HHS Office for Civil Rights also provides guidance on complying with civil rights laws enforced by HHS. Please see https://www.hhs.gov/civil-rights/for-individuals/section-1557/index.htmlhttps://www.hhs.gov/civil-rights/for-providers/laws-regulations-guidance/index.html.
