In Vivo Imaging and Function of Renal Tertiary Lymphoid Organs
Starzl Transplantation Institute, Pittsburgh.
Tertiary lymphoid organs (TLOs) are ectopic lymphoid structures that arise in non-lymphoid tissues in the setting of chronic inflammation such as organ transplantation. The function…2018 American Transplant Congress
TLR2 with TCR Signaling Mobilizes Treg Lymphatic Migration
Background: Regulatory T cells (Treg) express high levels of lymphotoxin (LT) and bind the LT receptor (LTβR) on lymphatic endothelial cells (LEC). This receptor-ligand interaction…2018 American Transplant Congress
Hematopoietic Cell Kinase (Hck) Regulates Effector and Regulatory T Cell (Treg) Function
Background: We found that upregulation of Hck mRNA expression, an Src family tyrosine kinase, in surveillance graft biopsies of kidney transplant patients associates with an…2018 American Transplant Congress
Preventing of Rejection of Vascularized Composite Allografts by Targeting T Cell Metabolism
[Background] Upon antigen recognition and co-stimulation, T lymphocytes upregulate the metabolic machinery necessary to proliferate and sustain effector function. This metabolic reprogramming in T cells…2018 American Transplant Congress
Central Role of Mef2 Transcription Factors in Regulation of Foxp3 Expression and Treg Function
1CHOP, Philadelphia; 2UPenn, Philadelphia.
Foxp3+ Tregs express 4 class IIa Hdac enzymes (Hdac4, 5, 7 & 9) with little or no catalytic activity and yet when deleted, at least…2018 American Transplant Congress
Shikonin Inhibits Th17 Development through Repressing STAT3 Activation
Background: Th17-mediated inflammatory responses are detrimental for allograft acceptance and long-term survival after transplantation. Shikonin is a naphthoquinone pigment isolated from a traditional medicinal herb…2018 American Transplant Congress
Rapamycin Impairs Human Endothelial Cell Alloimmunogenicity Independent of PD-1/PD-1 Ligand Inhibitory Signaling
Department of Surgery, Duke University Medical Center, Durham, NC.
Rapamycin prevents costimulation blockade (CoB)-resistant rejection in mice and primates, and early human data suggests a similar salutary effect. We have hypothesized that one mechanism…2018 American Transplant Congress
Targeting Calcium Release-Activated Calcium (CRAC) Channel in Non-Human Primate Kidney Transplantation
[Background] Long-term administration of calcineurin inhibitors (CNIs) successfully controls rejection of transplanted organs. However, the chronic use of these drugs causes organ damage often resulting…2018 American Transplant Congress
Activity Nanosensors for Early and Noninvasive Detection of Acute Organ Transplant Rejection
Purpose: We engineered activity nanosensors that sense anti-allograft T cell activity in vivo to noninvasively detect the onset of acute cellular rejection from urine.Methods: Granzyme…2018 American Transplant Congress
Belatacept-Refractory CD8+CD28–CD38hi Effector/Memory T Cells Are Targeted by mTOR Inhibition Leading to a Preferential Loss of CD40L
Calcineurin inhibitors (CNIs) and corticosteroids (CSS) have substantial untoward side effects, most notably nephrotoxicity. Consequently, the FDA approved belatacept for maintenance immunosuppression. We recently completed…
