TGF-β specifies T versus T17 cell fates in murine CD4 T cells through c-Maf.

T follicular helper (T) cells are essential for effective antibody responses, but deciphering the intrinsic wiring of mouse T cells has long been hampered by the lack of a reliable protocol for their generation in vitro. We report that transforming growth factor-β (TGF-β) induces robust expression of T hallmark molecules CXCR5 and Bcl6 in activated mouse CD4 T cells in vitro. TGF-β-induced mouse CXCR5 T cells are phenotypically, transcriptionally, and functionally similar to in vivo-generated T cells and provide critical help to B cells.

Deletion of the transcription factors Hsf1, Msn2 and Msn4 in yeast uncovers transcriptional reprogramming in response to proteotoxic stress.

The response to proteotoxic stresses such as heat shock allows organisms to maintain protein homeostasis under changing environmental conditions. We asked what happens if an organism can no longer react to cytosolic proteotoxic stress. To test this, we deleted or depleted, either individually or in combination, the stress-responsive transcription factors Msn2, Msn4, and Hsf1 in Saccharomyces cerevisiae.

Interventions to reduce stress and prevent burnout in healthcare professionals supported by digital applications: a scoping review.

Aim: Healthcare professionals are at increased risk of burnout, primarily due to workplace-related stressors. The COVID-19 pandemic has further increased this risk. Different interventions exist with varying degrees of effectiveness; little is reported on the content and implementation of such programs.

Depletion of the RNA-binding protein PURA triggers changes in posttranscriptional gene regulation and loss of P-bodies.

The RNA-binding protein PURA has been implicated in the rare, monogenetic, neurodevelopmental disorder PURA Syndrome. PURA binds both DNA and RNA and has been associated with various cellular functions. Only little is known about its main cellular roles and the molecular pathways affected upon PURA depletion.
