The cell of origin for Barrett’s esophagus

SummaryBarrett's esophagus (BE) is a premalignant condition with increased risk for the development of esophageal adenocarcinoma (EAC). Surveillance relies on regular endoscopy with biopsies to detect dysplasia (disordered cellular growth)…

Keeping warm one cell at a time

Adipose thermogenesis is a conserved response to environmental cold or dietary excess and is classically triggered by ligand-dependent receptor activation. Johansen et al. report that cold regulation of Gs-coupled receptor expression…

Boosting stem cell immunity to viruses

SummaryMammalian stem cells exhibit deficiencies in innate immunity regulated by interferons (IFNs), so they rely on constitutive expression of some IFN-stimulated genes (ISGs) (1) and Argonaute 2 (AGO2)–dependent RNA interference (RNAi)…

T cell receptor dynamics | Science

T cells are thought to integrate information from multiple encounters with antigen-presenting cells to become activated. To explore how the dynamics of T cell receptor signaling influence such a process, Harris et al. developed an optically…

A LoCK at the T cell dock

SummaryThe stimulation of T cells with foreign or self-antigens plays a central role in the adaptive immune responses to infection and cancer but also in autoimmunity. T cells use a sophisticated molecular machinery to recognize and respond…
