Upregulated IL-33 in Heart Transplants Modulates Local Myeloid Populations to Protect against Chronic Allograft Rejection
Purpose: Interleukin-33 (IL-33) is an “alarmin”, or a self-derived molecule that triggers pleotropic immune responses after release from damaged tissue. Yet, how IL-33 shapes alloresponses…2018 American Transplant Congress
Ablation of Both mTOR and STAT3 in T Cells Induces Heart Transplant Acceptance in Donor Skin-Sensitized Mice
Allogeneic memory T cell response precludes the induction of transplant acceptance; how this process is regulated at the molecular level remains unclear. Both mTOR and…2018 American Transplant Congress
Lymph Node Stromal Laminins Affect Graft Survival through Regulation of CD4 T Cell Proliferation and Migration
University of Maryland, Baltimore, MD.
Background: Our prior studies demonstrated that tolerance and immunity are associated with differential expression of lymph node (LN) stromal laminins α4β1γ1 (411) and α5β1γ1 (511),…2018 American Transplant Congress
Lymphotoxin Beta Receptor Modulation in Lymphatic Endothelial Cells Alters Regulatory T Cell Dynamics
Background:Lymphotoxin beta receptor (LTβR) mediated signaling in lymphatic endothelium cells (LEC) is important for migration of regulatory T cells (Treg) to afferent lymphatic vessels (LV)…2018 American Transplant Congress
Role of B Cell Intrinsic NLRP3 in the Development of Chronic Rejection
Endogenous DAMPs elicited during transplantation are recognized via TLR-MyD88 and NLRP3-inflammosome pathways that are expressed in APCs including B cells. Here, we asked whether B…2018 American Transplant Congress
Recipient Conditioning Results in IL-33 Support of Potent Th1 Alloimmune Responses after CD4+ T Cells Upregulate ST2 during Lymphopenia Induced Proliferation
Purpose: IL-33 is typically associated with support of Th2 and Treg responses. Yet, recipient conditioning before allogeneic hematopoietic cell transplantation (alloHCT) releases IL-33 to promote…2017 American Transplant Congress
Abrogating MyD88 Signaling in Donor Lung Resident Hematopoietic Cells Promotes Cell Based Tolerance Induction in Lung Allografts in Mice.
Objectives: MyD88 signaling plays an important role in allograft rejection and tolerance induction. This study is designed to determine the cellular base of MyD88 expression…2017 American Transplant Congress
Deleting LAG-3 Accelerates Cardiac Allograft Rejection and Augments T Cell Memory in Mice.
Purpose: Lymphocyte Activation Gene-3 (LAG-3) expresses a transmembrane receptor on activated immune cells such as T cells, NK cells, and plasmacytoid dendritic cells. It is…2017 American Transplant Congress
Recipient iNOS Deficiency Reduces Spontaneous Kidney Allograft Acceptance by Accelerating Allograft Loss.
Center for Transplantation Sciences, Massachusetts General Hospital, Boston, MA
Nitric oxide (NO) production by inducible nitric oxide synthase (iNOS), encoded by NOS2, is a hallmark of the innate immune axis, and is typically associated…2017 American Transplant Congress
mTORC1 and 2 Regulate Dendritic Cell (DC) Metabolism and Allostimulatory Function of Donor DCs in Skin Transplantation.
Background/Hypothesis: The mechanistic target of rapamycin (mTOR) is a kinase that functions in two complexes: rapamycin (RAPA)-sensitive mTORC1 and RAPA-insensitive mTORC2. These complexes play critical…
