Use of organ-culture, irradiation and adoptive-transfer to investigate the role of the xenopus thymus in t lymphocyte development [PDF]

open access: yes, 1986
This Thesis attempts to develop an amphibian model system for exploring the role of the thymus, particularly its stromal cells, in the acquisition of allotolerance. Inbred, clonal and cytogenetically- marked Xenopus are used in this work.

Loss of proton‐sensing TDAG8 increases tumor progression in mouse models of colon cancer

open access: yesMolecular Oncology, EarlyView.
Loss of the pH‐sensing receptor TDAG8 accelerates colorectal cancer progression in mice. Animals lacking TDAG8 expression had increased tumor growth, DNA damage, and recruitment of tumor‐associated immune cells, including macrophages, neutrophils, and monocytes.

European multicentre study on outcome of surgery for sporadic primary hyperparathyroidism

open access: yesBJS (British Journal of Surgery), EarlyView., 2020
Some 5861 patients undergoing first‐time surgery for sporadic primary hyperparathyroidism were registered in the Eurocrine® database between 2015 and 2018. The use of intraoperative parathyroid hormone measurement decreased the risk of conversion and persistent hypercalcaemia.

CT density of cervical thymus, in comparison with mediastinal thymus

open access: yesInsights 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

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

open access: yeseLife, 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 ...

Tumours of the Thymus [PDF]

open access: yesUpsala Journal of Medical Sciences, 1975
A series of 22 consecutive cases of thymic tumour was collected and the tumours were reclassified according to a modified classification scheme. Two-thirds of them were benign lympho-epitheliomas, though in one case pleural implants were noted. One-third of the tumours were clearly malignant (carcinomas, lymphomas and seminomas).

The role of neural crest cells in the development, organisation and migration of the thymus [PDF]

open access: yes, 2010
Neural Crest (NC) derived mesenchyme has previously been shown to play an important role in the early development of the foetal thymus. Using Wnt1-Cre and Sox10-Cre mice crossed to Rosa26eYfp reporter mice, NC derived mesenchymal cells were revealed in

The role of the transcription factor Sox9 for thymic epithelial cell differentation and function [PDF]

open access: yes, 2011
The thymus provides throughout life the specialized stromal microenvironment required for the lifelong generation of naïve T cells. This vital function is dependent on the regular composition and organization of its microenvironment, where specialized ...

Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level

open access: yesAging and Cancer, EarlyView.
This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...

T-cells and transplantation tolerance in Thymectomised Xenopus implanted with foreign thymus [PDF]

open access: yes, 1990
This thesis investigates the expression of a T-cell differentiation antigen, (XTLA- 1), in various strains and species of Xenopus, and demonstrates the effect of early-thymectomy, (by microcautery), on XTLA-1 expression.
