    OPA1 deletion in brown adipose tissue improves thermoregulation and systemic metabolism via FGF21

    Renata O Pereira et al.
    Lack of OPA1 in BAT impairs its thermogenic activation and induces endoplasmic reticulum stress, while improving systemic metabolism and thermoregulation via ATF4-FGF21-dependent and -independent mechanisms.

    Response-based outcome predictions and confidence regulate feedback processing and learning

    Romy Frömer et al.
    Computational modeling, and empirical behavioral and EEG results show that learning relies not only on comparing current events to past experience, but integrates response-based outcome predictions and confidence.

    IL-33 promotes innate lymphoid cell-dependent IFN-γ production required for innate immunity to Toxoplasma gondii

    Joseph T Clark et al.
    Upon Toxoplasma gondii infection, IL-33 plays a critical role in driving early anti-parasite responses by innate lymphoid cells rendered responsive to its effects by infection.

    The final step of 40S ribosomal subunit maturation is controlled by a dual key lock

    Laura Plassart et al.
    Cryo-EM and functional studies reveal how combined action of proteins RPS26/eS26 and RIO1 allows late precursors to the human small ribosomal particle to be matured into fully translation-competent 40S subunits.

    An NKX2-1/ERK/WNT feedback loop modulates gastric identity and response to targeted therapy in lung adenocarcinoma

    Rediet Zewdu et al.
    Genetically engineered murine models reveal novel mechanisms of cell identity regulation in lung cancer and provide insights into the complex interplay between lineage specifiers and oncogenic signaling pathways in this disease.

    An open label trial of anakinra to prevent respiratory failure in COVID-19

    Evdoxia Kyriazopoulou et al.
    Early suPAR-guided anakinra decreases the risk for severe respiratory failure in SARS-CoV-2 pneumonia and restores the pro-/anti-inflammatory balance.

    Disparate bone anabolic cues activate bone formation by regulating the rapid lysosomal degradation of sclerostin protein

    Nicole R Gould et al.
    Mechanical loading and the bone anabolic action of parathyroid hormone result in rapid, lysosomal degradation of sclerostin protein, revealing physiologically important post-translational control of this critical regulator of bone formation.
