- The National Institute of Allergy and Infectious Diseases, a component of the Department of Health and Human Services National Institutes of Health, awarded $427,623 to The Washington University on February 24, 2026, under the Allergy and Infectious Diseases Research program (CFDA 93.855) to support research dissecting how HIV-induced immunometabolic perturbation impairs tuberculosis control in people living with HIV despite effective antiretroviral therapy and viral suppression. The research...
- The National Institute of Allergy and Infectious Diseases awarded The Washington University $305,908 on December 23, 2025, under the Allergy and Infectious Diseases Research program (CFDA 93.855) to investigate mechanisms of sigma-factor-dependent transcriptional control in Mycobacterium tuberculosis. The research employs experimental and computational approaches to understand the role of an intrinsically disordered region (IDR) in the sigma-A factor, which directs RNA polymerase to genes across...
- The National Institute of Allergy and Infectious Diseases awarded Saint Louis University $259,125 on April 1, 2026, under the Allergy and Infectious Diseases Research program (CFDA 93.855) to dissect the contribution of neutrophils to diabetes and tuberculosis comorbidity. The research investigates how altered neutrophil function in diabetic patients increases susceptibility to active tuberculosis disease and worsens outcomes. The project examines neutrophilic inflammation as a central feature...
- The National Institute of Allergy and Infectious Diseases awarded The Washington University $233,250 on June 1, 2026, under the Allergy and Infectious Diseases Research program (CFDA 93.855) to model toll-like receptor 8 gain-of-function disease mechanisms and identify potential therapeutic targets. The project investigates a newly identified inborn error of immunity caused by genetic variants in TLR8, an X-linked endosomal receptor expressed in myeloid cells. The disease presents with...
- The National Heart, Lung, and Blood Institute awarded The Washington University $680,379 on July 1, 2026, under the Cardiovascular Diseases Research program (CFDA 93.837) to investigate the role of sphingolipid biosynthesis during lung infection, specifically examining how SPTLC2, an essential enzyme subunit in sphingolipid synthesis, affects survival during Mycobacterium tuberculosis infection in CD11C+ lung macrophages and dendritic cells. The project addresses immune response mechanisms...
- The National Institute of Allergy and Infectious Diseases awarded Saint Louis University $192,500 on February 13, 2026, under the Allergy and Infectious Diseases Research program (CFDA 93.855) to investigate the molecular mechanisms by which a monocyte chemoattractant protein-1 (MCP-1) promoter polymorphism confers susceptibility to pulmonary tuberculosis infection. The research addresses why approximately 10% of individuals infected with Mycobacterium tuberculosis progress to active pulmonary...
- The National Institute of Allergy and Infectious Diseases awarded University of Massachusetts Medical School $139,968 on September 30, 2025, under the Allergy and Infectious Diseases Research program (CFDA 93.855) to investigate the relationship between genetic variants, transcriptional responses, and Mycobacterium tuberculosis infection outcomes in macrophages derived from genetically diverse Collaborative Cross mice. The research explores how polymorphisms such as those in the STAT2 locus...
- The National Institute of Allergy and Infectious Diseases awarded The Washington University $664,076 on April 1, 2026, under the Allergy and Infectious Diseases Research program (CFDA 93.855, Project Grant R01AI196089) to investigate the molecular mechanisms by which Staphylococcus aureus alpha-toxin impairs antigen-specific T cell response and adaptive immunity. The research examines how S. aureus alpha-toxin (HLA) functions as a virulence factor and potential vaccine target. The work...
- The National Institute of Allergy and Infectious Diseases awarded The Washington University $638,220 on April 1, 2026, under the Allergy and Infectious Diseases Research program (CFDA 93.855) to investigate DNA ADP-ribosylation in bacterial-phage immune conflicts. The research examines how DNA ADP-ribosylation, a chemical modification that blocks DNA replication and serves as a bacterial anti-phage defense mechanism, operates across bacterial toxin-antitoxin systems and phage counter-mechanisms....
- The National Institute of Allergy and Infectious Diseases awarded the University of Missouri System $2.767 million on August 1, 2026, under the Allergy and Infectious Diseases Research program (CFDA 93.855) to investigate the NFKB signaling network in the regulation of resident T cell memory. The research addresses how tissue-resident memory T cells (TRM) are generated and maintained in the lungs following infection. While CD8 TRM cells in multiple tissues provide superior protection against...
The National Institute of Allergy and Infectious Diseases awarded Washington University $466,500 on August 1, 2026, under the Allergy and Infectious Diseases Research program (CFDA 93.855) to investigate aberrant wound healing responses that drive myeloid-dependent disease exacerbation in mycobacterium tuberculosis infection. The research leverages existing single-cell RNA-sequencing datasets and generates new spatial transcriptomic profiling of human and mouse MTB-infected lungs to identify drivers of SPP1+ macrophage differentiation. The project hypothesizes that SPP1+ macrophages—a newly identified fate present in MTB-susceptible but not MTB-restrictive mice and correlated with disease severity in infected human lungs—arise in response to chronic inflammation and subsequently drive an aberrant wound healing response that limits productive immune responses. Candidate drivers will be validated using in vivo CRISPR/CAS9 screening and confirmed with mouse genetic approaches. The research extends beyond tuberculosis to examine SPP1+ macrophage differentiation in cancer, severe COVID-19, and rheumatoid arthritis. Performance occurs in St. Louis, Missouri, with a period of performance from August 1, 2026, through July 31, 2031. Washington University's Office of Sponsored Research Services Division receives and administers the award.
