The Transcription Factor MAZR/PATZ1 Regulates the Development of FOXP3+ Regulatory T Cells
2019
Summary: Forkhead box protein P3+ (FOXP3+) regulatory T cells (Treg cells) play a key role in maintaining tolerance and immune homeostasis. Here, we report that a T cell-specific deletion of the transcription factor MAZR (also known as PATZ1) leads to an increased frequency of Treg cells, while enforced MAZR expression impairs Treg cell differentiation. Further, MAZR expression levels are progressively downregulated during thymic Treg cell development and during in-vitro-induced human Treg cell differentiation, suggesting that MAZR protein levels are critical for controlling Treg cell development. However, MAZR-deficient Treg cells show only minor transcriptional changes ex vivo, indicating…
Isolation of T Cells from the Skin
2014
T cells can be found in skin under steady-state conditions as well as in inflammatory processes. T cells in skin play an important role in immune homeostasis as well as control of infectious, inflammatory diseases or tumors. In addition, several important and frequent skin diseases such as psoriasis, atopic dermatitis, autoimmune disease, and contact allergy are initiated by T cells. In skin diseases, the majority of antigen-specific T cells can be found in the tissue, not the peripheral blood. Here, we present a protocol suitable for isolation of skin-resident (inflammatory) T cells that can be used for an in-depth characterization of their frequency, function, and role for the respective …
