Ssu72 Is a T-cell Receptor-Responsive Modifier That Is Indispensable for Regulatory T Cells

The authors found that the Ssu72 phosphatase was activated by various T-cell receptor signaling pathways, including the T-cell receptor and IL-2R pathways, and localized at the cell membrane.

UTX Promotes CD8+ T Cell-Mediated Antiviral Defenses but Reduces T Cell Durability

Investigators showed that T cell receptor-stimulated CD8+ T cells increased their expression of ubiquitously transcribed tetratricopeptide repeat, X chromosome (UTX) to enhance gene expression.

Interleukin-17D Regulates Group 3 Innate Lymphoid Cell Function through Its Receptor CD93

Researchers examined the role of IL-17D, a poorly understood member in the IL-17 family. Il17d−/− mice were more susceptible to acute colitis, bacterial infection and experimentally induced colon cancer than their wildtype counterparts.

Cell Barrier Function of Resident Peritoneal Macrophages in Post-Operative Adhesions

The authors showed that resident F4/80HighCD206− peritoneal macrophages promptly accumulate on the lesion and form a ‘macrophage barrier’ to shield fibrin clots in place of the lost mesothelium in mice.
