Neutrophil CEACAM1 Induces Hepatic Autophagy and Shapes Innate-adaptive Immune Response in Liver Transplantation: From Mouse-to-human
1Surgery, Dumont-UCLA Transplant Center, Los Angeles, CA, 2Surgery, Kyoto University, Kyoto, Japan
*Purpose: Although CEACAM1 (CC1; carcinoembryonic antigen-related cell adhesion molecule 1; CD66a) regulates innate-adaptive immunity, its role in orthotopic liver transplantation (OLT) remains unknown. CC1 expresses…2021 American Transplant Congress
Tip60 Inhibitors Enhance Regulatory T Cells (Treg) Induction by Promoting Acetylation of Foxp3
*Purpose: TIP60, a histone/protein acetyltransferase essential for multiple functions in the cell, is involved in Foxp3 acetylation in Treg. Acetylation protects Foxp3 from degradation, and…2021 American Transplant Congress
Donor Kidney-Resident Macrophages Promote Allograft Inflammation and CD8 T Cell Response Post-Transplantation
*Purpose: Kidney-resident macrophages play important roles in maintaining normal kidney function and promoting prompt repair following kidney injuries. Nevertheless, their fate and role in kidney…2021 American Transplant Congress
Quantifying Hidden Sensitization: HLA-reactive Memory B Cells in the Spleens of Sensitized Women
*Purpose: Measurement of circulating anti-HLA antibody (anti-HLA-Ab) in transplant candidates and recipients is required for successful organ transplantation. However, serum Ab measurement alone likely underestimates…2021 American Transplant Congress
Mhealth Family Self-Management Intervention for Families of Transplanted Children
*Purpose: Nearly 2,000 children undergo solid organ transplant in the US annually. In our previous research with transplant families, parents reported difficulty coping with the…2021 American Transplant Congress
Estrogen Receptors Alpha and Beta are Required for Immune Homeostasis and Normal Treg Function
*Purpose: Estrogen signaling is a critical component of mammalian homeostasis, acting through a complex and interconnected system of hormone synthesis pathways and receptor signaling cascades.…2021 American Transplant Congress
Regulatory Macrophage Induced by Il-33 Promoted Immune Tolerance of Kidney Transplantation Through Siglec-10
Urology, Beijing Chaoyang Hospital, Capital Medical University, Beijing, China
*Purpose: Acute and chronic rejection are key problems in renal transplantation. It is ideal to induce immune tolerance to suppress rejection while regulatory macrophages (Mregs)…2021 American Transplant Congress
Islet Isograft Transplantation Improves Insulin Sensitivity in a Murine Model of Type 2 Diabetes
Asan Medical Center, Seoul, Songpa, Korea, Republic of
*Purpose: Type 2 diabetes develops in the presence of chronic overnutrition and genetic susceptibility, and causes insulin resistance and relative insulin deficiency. We hypothesized that…2021 American Transplant Congress
The Co-Occurrence of Newly Developed HLA Donor Specific Antibody and Positive C3d/C4d Profiles Along with Immune Therapy Non-Compliance in Pediatric Heart Transplant Recipients is a High Risk Indicator for Patient Mortality
Cleveland Clinic Foundation Transplant Center, Cleveland, OH
*Purpose: Increasing evidence has implicated the deleterious effect of HLA donor specific antibody (DSA) in pediatric heart transplantation (PHTx). However, there are still insufficient research…2021 American Transplant Congress
Transforming Growth Factor-Beta Induced Myeloid-Derived Suppressor Cells Promote Transplant Immune Tolerance
*Purpose: Myeloid-derived suppressor cells (MDSCs) are a group of heterogeneous cells derived from bone marrow with immunosuppressive effect, which contribute to the establishment of transplant…
