2020-2025 NIH
Senescent cells drive mt-DNA accumulation and inflamm-aging
Research Grant #: R01AG064165-01A1
Role:  PI
The major goals of this project are to dissect pathways driving augmented immunogenicity and compromised repair in old organs. We are prepared to investigate, in-depth, novel and age-specific therapies that will facilitate the utilization and optimize outcomes of older organs in transplantation

2021-2026 NIH
The KAPP-Sen Tissue Mapping Center Collaborative
Research Grant #: U54AG075941-01
Role:  Co-Investigator/Site PI
The major goal is to enhance understanding of the role of senescent cells in aging and chronic diseases. Dr. Tullius will serve as the co-lead of the biorepository core and will provide the consortium with advice on clinical assessment, tissue collection, storage and shipment, and will provide the consortium with samples of kidney, fat and skin from healthy living donors with a representative distribution of gender and age.

Pablo and Almudena Legorreta Kidney Health Research Fund:
Moving organ rejuvenation into clinical application
Role:  PI

2024-2029 Hevolution Foundation
Delineating the Interference of Cellular Senescence in Organ Transplantation
Research Grant #: HF-GRO-23-1199238-25
Role: PI
Senescence critically drives immunogenicity and chronic graft deterioration while molding alloimmunity. The major goals of this project are to define mechanisms of these processes and targeting senescent cells has the potential to significantly improve organ utilization and transplant outcomes.

2024-2029 NIH
Program Project Grant: Aging and transplant immunity, Project 2: Mechanisms and novel targets of T-cell Immunity in Aging
Role: Project Leader
Research Grant #: P01AI175397-02
The major goals of this project are to investigate how aging rewires alloimmunity with critical effects on allorecognition, DC/T cell interaction, and T cell metabolism. We will provide novel opportunities for a refined immunosuppression in older recipients.

2024 SBIR/STTR Phase I, NSF
Non-invasive focused ultrasound treatment to modulate the immune system for acute and chronic kidney rejection
Role: Co-PI
Research Grant #: 2312694
This project aims to develop an external system for reducing inflammatory responses thereby reducing adverse events associated with the transplant and extending the lifetime of the new organ.
