Role of Hormonal Circuitry Upon T Cell Development in Chagas Disease: Possible Implications on T Cell Dysfunctions

Frontiers in Endocrinology, 2018
T cell response plays an essential role in the host resistance to infection by the protozoan parasite Trypanosoma cruzi, the causative agent of Chagas disease.

Effect of GnRH immunocastration on immune function in male rats

Frontiers in Immunology, 2023
The present study aimed to reveal the effects of immunocastration on the development of the immune system in rats. Seventy rats were randomly assigned into two groups: Control (n = 35) and immunized (n = 35).

CT density of cervical thymus, in comparison with mediastinal thymus

Insights into Imaging, 2019
Objectives Cervical component of thymus is noted more in children and young adults than in older age group. CT texture (lobules of soft tissue interspersed with fat), similarity with CT density of mediastinal thymus and continuity with mediastinal thymus

Metabolic Regulation of Thymic Epithelial Cell Function

Frontiers in Immunology, 2021
The thymus is the primary site of T lymphocyte development, where mutually inductive signaling between lymphoid progenitors and thymic stromal cells directs the progenitors along a well-characterized program of differentiation.

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.

Aire-dependent genes undergo Clp1-mediated 3’UTR shortening associated with higher transcript stability in the thymus

eLife, 2020
The ability of the immune system to avoid autoimmune disease relies on tolerization of thymocytes to self-antigens whose expression and presentation by thymic medullary epithelial cells (mTECs) is controlled predominantly by Aire at the transcriptional ...

Regulation of γδ T Cell Effector Diversification in the Thymus

Frontiers in Immunology, 2020
γδ T cells are the first T cell lineage to develop in the thymus and take up residence in a wide variety of tissues where they can provide fast, innate-like sources of effector cytokines for barrier defense.

Regulation of IkappaB Protein Expression by Early Gestation in the Thymus of Ewes

Veterinary Sciences, 2023
The thymus is an essential component of maternal immune systems that play key roles in recognizing the placenta as immunologically foreign. The inhibitor of the NF-κB (IκB) family has essential effects on the NF-κB pathway; however, it is unclear whether

Pictorial essay. Pathology of the thymus on CT-imaging.

Journal of the Belgian Society of Radiology, 2012
A number of masses arise in relation to the thymus. The radiologist has an important role regarding the differential diagnosis between non-tumoral thymic pathology and malignant thymic tumors.

Functionally diverse thymic medullary epithelial cells interplay to direct central tolerance

Cell Reports
Summary: Medullary thymic epithelial cells (mTECs) are essential for the establishment of self-tolerance in T cells. Promiscuous gene expression by a subpopulation of mTECs regulated by the nuclear protein Aire contributes to the display of self-genomic ...
