    Respiratory and intestinal epithelial cells exhibit differential susceptibility and innate immune responses to contemporary EV-D68 isolates

    Megan Culler Freeman, Alexandra I Wells ... Carolyn B Coyne
    Parallel studies in primary human airway cells and stem cell-derived enteroids show that Enterovirus D-68 differentially infects and induces innate immune signaling in the respiratory and intestinal epithelium.

    Trisomy 21 consistently activates the interferon response

    Kelly D Sullivan, Hannah C Lewis ... Joaquín M Espinosa
    Hyperactive interferon signaling is a hallmark of trisomy 21 and may contribute to many of the comorbidities associated with Down syndrome.

    Single cell analysis reveals human cytomegalovirus drives latently infected cells towards an anergic-like monocyte state

    Miri Shnayder, Aharon Nachshon ... Michal Schwartz
    Single-cell and bulk expression analyses reveal that HCMV latent infection drives cells towards a weaker immune-responsive state, which is important for its expression and reactivation.

    Targeting senescent cells enhances adipogenesis and metabolic function in old age

    Ming Xu, Allyson K Palmer ... James L Kirkland
    Senescent cells contribute to age-related fat dysfunction and can directly impair healthy fat progenitor function, in part, via the secretion of activin A.

    MicroRNA-deficient mouse embryonic stem cells acquire a functional interferon response

    Jeroen Witteveldt, Lisanne I Knol, Sara Macias
    MiRNA-mediated suppression of MAVS expression in embryonic stem cells is necessary to inactivate the type I interferon response.

    Hepatitis C virus exploits cyclophilin A to evade PKR

    Che C Colpitts, Sophie Ridewood ... Greg J Towers
    Hepatitis C virus evades IRF1-dependent intrinsic antiviral immunity by exploiting cyclophilin A and its regulation of PKR.

    FXR1 regulates transcription and is required for growth of human cancer cells with TP53/FXR2 homozygous deletion

    Yichao Fan, Jiao Yue ... Bin Xiang
    Functional and mechanistic analyses of cancer cells containing homozygous deletion of TP53 and FXR2 reveal that inhibition of FXR1 blocks cell proliferation in a collateral lethality manner, opening an avenue to develop therapies targeting such cancers.

    Tyrosine phosphorylation tunes chemical and thermal sensitivity of TRPV2 ion channel

    Xiaoyi Mo, Peiyuan Pang ... Jing Yao
    Mg2+-dependent JAK1-mediated phosphorylation sensitizes TRPV2 activity and thermo-threshold, which is counterbalanced by PTPN1-mediated dephosphorylation, highlighting a role of phosphorylation homeostasis in setting the basal activity of TRPV2.

    Innate immune signaling in trophoblast and decidua organoids defines differential antiviral defenses at the maternal-fetal interface

    Liheng Yang, Eleanor C Semmes ... Carolyn B Coyne
    Organoids developed from matched human placental tissue define differences in antiviral signaling between cell types comprising the maternal-fetal interface.
