RANK Signaling in the Differentiation and Regeneration of Thymic Epithelial Cells

Frontiers in Immunology, 2021
Thymic epithelial cells (TECs) provide essential clues for the proliferation, survival, migration, and differentiation of thymocytes. Recent advances in mouse and human have revealed that TECs constitute a highly heterogeneous cell population with ...

Editing T cell repertoire by thymic epithelial cell-directed gene transfer abrogates risk of type 1 diabetes development

Molecular Therapy: Methods & Clinical Development, 2022
Insulin is the primary autoantigen (Ag) targeted by T cells in type 1 diabetes (T1D). Although biomarkers precisely identifying subjects at high risk of T1D are available, successful prophylaxis is still an unmet need.

Exploring the Origin and Antigenic Specificity of Maternal Regulatory T Cells in Pregnancy

Frontiers in Immunology, 2020
Successful pregnancy outcome is partially determined by the suppression of reactive effector T cells by maternal regulatory T cells (TRegs) at the maternal-fetal interface.

Mechanisms of Direct and Indirect Presentation of Self-Antigens in the Thymus

Frontiers in Immunology, 2022
The inevitability of evolution of the adaptive immune system with its mechanism of randomly rearranging segments of the T cell receptor (TCR) gene is the generation of self-reactive clones. For the sake of prevention of autoimmunity, these clones must be

Post-Aire Medullary Thymic Epithelial Cells and Hassall’s Corpuscles as Inducers of Tonic Pro-Inflammatory Microenvironment

Frontiers in Immunology, 2021
While there is convincing evidence on the role of Aire-positive medullary thymic epithelial cells (mTEC) in the induction of central tolerance, the nature and function of post-Aire mTECs and Hassall’s corpuscles have remained enigmatic. Here we summarize

Thymic Epithelial Cell Alterations and Defective Thymopoiesis Lead to Central and Peripheral Tolerance Perturbation in MHCII Deficiency

Frontiers in Immunology, 2021
Major Histocompatibility Complex (MHC) class II (MHCII) deficiency (MHCII-D), also known as Bare Lymphocyte Syndrome (BLS), is a rare combined immunodeficiency due to mutations in genes regulating expression of MHCII molecules.

Alloactivation of Naïve CD4+CD8−CD25+T Regulatory Cells: Expression of CD8α Identifies Potent Suppressor Cells That Can Promote Transplant Tolerance Induction

Frontiers in Immunology, 2019
Therapy with alloantigen-specific CD4+CD25+ T regulatory cells (Treg) for induction of transplant tolerance is desirable, as naïve thymic Treg (tTreg) are not alloantigen-specific and are weak suppressor cells.

MHC Class II Presentation in Autoimmunity

Cells, 2023
Antigen presentation by major histocompatibility complex class II (MHC-II) molecules is crucial for eliciting an efficient immune response by CD4+ T cells and maintaining self-antigen tolerance.

Association between one-hour post-load plasma glucose levels and vascular stiffness in essential hypertension [PDF]

, 2012
Objectives: Pulse wave velocity (PWV) is a surrogate end-point for cardiovascular morbidity and mortality. A plasma glucose value $155 mg/dl for the 1-hour post-load plasma glucose during an oral glucose tolerance test (OGTT) is able to identify ...
