Generation of a functional and self-tolerant T cell repertoire is a complex process dependent on the thymic microenvironment and, primarily, on the properties of its extracellular matrix (ECM). Thymic epithelial cells (TECs) are crucial in thymopoiesis, nurturing and selecting developing T cells by filtering self-reactive clones. TECs have been empirically demonstrated to be particularly sensitive to physical and chemical clues supplied by the ECM and classical monolayer cell culture leads to a quick loss of functionality until their death.

- Autoimmune polyendocrine syndrome type 1 (APS-1) is a severe genetic disorder resulting from AIRE deficiency, leading to self-reactive T cells causing autoimmune damage in various organs.
- The study investigated the role of interferon-γ in APS-1 by analyzing patient samples and conducting experiments with mice, finding that high levels of interferon-γ correlate with disease activity.
- Treatment with the JAK inhibitor ruxolitinib significantly reduced interferon-γ levels and improved symptoms in APS-1 patients, suggesting that targeting this pathway may be a viable therapeutic approach.
Biomarkers that could predict the evolution of the graft in transplanted patients and that could allow to adapt the care of the patients would be an invaluable tool. Additionally, certain biomarkers can be target of treatments and help to stratify patients. Potential effective biomarkers have been identified but still need to be confirmed.

Amelogenesis depends on multiple ameloblast-derived proteins that function as a scaffold for hydroxyapatite crystals. The loss of function of ameloblast-derived proteins results in a group of rare congenital disorders called amelogenesis imperfecta.
