Background: T cell tolerance both at thymic and peripheral levels is a mechanism of protection finalized to eradicate autoreactive T cell clones and/or to maintain immune homeostasis, especially, postnatally. Central tolerance occurs in the thymic medulla via a mechanism of negative selection which leads to the eradication of autoreactive T cell clones. Mechanisms of action: Such a tolerogenic event relies on Fas-mediated apoptosis of autoreactive T cell clones operated by thymic dendritic cells (DCs), on the one hand. Read More

Hassall's corpuscles (HCs) are composed of cornifying, terminally differentiated medullary thymic epithelial cells (mTECs) that are developed under the control of Aire. Here, we demonstrated that HC-mTECs show features of cellular senescence and produce inflammatory cytokines and chemokines including CXCL5, thereby recruiting and activating neutrophils to produce IL-23 in the thymic medulla. We further indicated that thymic plasmacytoid dendritic cells (pDCs) expressing IL-23 receptors constitutively produced Ifna, which plays a role in single positive (SP) cell maturation, in an Il23a-dependent manner.

Purpose: Type I interferon (IFN-I) and IL-22 modulate regeneration of the thymus and intestinal epithelial cells (IECs) after cytotoxic stress like irradiation. Radiation-induced damage to thymic tissues and IECs is a crucial aspect during the pathogenesis of inadequate immune reconstitution and acute graft-versus-host disease (GVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) with myeloablative total body irradiation (TBI), respectively.

Purpose Of Review: The purpose of this review is to describe the recent advances that have been made in understanding the protective role of prostaglandin E2 (PGE2) in aspirin-exacerbated respiratory disease (AERD), known in Europe as NSAID-exacerbated respiratory disease (N-ERD).
Recent Findings: Decreased PGE2 signaling through the EP2 receptor in patients with AERD leads to an increase in leukotriene synthesis and signaling. Leukotriene signaling not only directly activates group 2 innate lymphoid cells and mast cells, but it also increases production of IL-33 and thymic stromal lymphopoietin. Read More

In nearly every species examined, administration of the persistent environmental pollutant, 2,3,7,8-tetrachlorodibenzo-p-dioxin (dioxin, TCDD) causes profound immune suppression and thymic atrophy in an aryl hydrocarbon receptor (AhR) dependent manner. Moreover, TCDD alters the development and differentiation of thymocytes, resulting in decreases in the relative proportion and absolute number of double positive (DP, CD4CD8) thymocytes, as well as a relative enrichment in the relative proportion and absolute number of double negative (DN, CD4CD8) and single-positive (SP) CD4CD8 and CD4CD8 thymocytes. Previous studies suggested that the target for TCDD-induced thymic atrophy resides within the hemopoietic compartment and implicated apoptosis, proliferation arrest of thymic progenitors, and emigration of DN thymocytes to the periphery as potential contributors to TCDD-induced thymic atrophy.

Although not a disease itself, aging represents a risk factor for many aging-related illnesses, including cancer. Numerous causes underlie the increased incidence of malignancies in the elderly, for example, genomic instability and epigenetic alterations that occur at cellular level, which also involve the immune cells. The progressive decline of the immune system functions that occurs in aging defines immunosenescence, and includes both innate and adaptive immunity; the latter undergoes major alterations. Read More

Self-tolerance, the state of unresponsiveness to self-tissues/antigens, is maintained through central and peripheral tolerance mechanisms, and a breach of these mechanisms leads to autoimmune diseases. Foxp3 + T-regulatory cells (Tregs) play an essential role in suppressing autoimmune response directed against self-antigens and thereby regulate self-tolerance. Natural Tregs are differentiated in the thymus on the basis of their higher TCR-affinity to self-antigens and migrate to the periphery where they maintain peripheral tolerance. Read More

An immunocompetent and self-tolerant pool of naive T cells is formed in the thymus through the process of repertoire selection. T cells that are potentially capable of responding to foreign antigens are positively selected in the thymic cortex and are further selected in the thymic medulla to help prevent self-reactivity. The affinity between T-cell antigen-receptors (TCRs) expressed by newly generated T cells and self-peptide-MHC complexes displayed in the thymic microenvironments plays a key role in determining the fate of developing T cells during thymic selection.

However, the role of thymic selection in these conditions is much less well understood.
