     This valuable study by Cui et al. investigates mechanisms generating sighs, which are crucial for respiratory function and linked to emotional states. Utilizing advanced methods in mice, they provide solid evidence that increased excitability in specific preBötzinger complex neuronal subpopulations expressing Neuromedin B receptors, gastrin-releasing peptide receptors, or somatostatin can induce sigh-like large amplitude inspirations. With additional technical clarifications and further elaboration of the limitations in terms of how the results are interpreted in the revised manuscript, the study will interest neuroscientists studying respiratory neurobiology and rhythmic motor systems.

     This is an important study that utilizes proteomic and genetic approaches to identify the glycoprotein quality control factor malectin as a pro-viral host protein involved in the replication of coronavirus. The evidence supporting this conclusion is convincing, although continued elucidation of the mechanistic basis of malectin-mediated viral replication would further strengthen these findings. This work will be of interest to cell biologists studying the molecular mechanisms of glycoprotein quality control and virologists studying the host-pathogen interactions.

     This is a useful paper regarding the roles of brown adipose tissue and skeletal muscle in thermogenesis in mice, with potential significance for the field. The overall approach is innovative but on balance the evidence for the claim is incomplete, as cast immobilization, while innovative, is likely stressful, may impact muscle and BAT directly, and imposes an energetic cost of motion on the animal that is not accounted for. Further experiments are also needed to directly assess the role of adipose-derived BCAAs in thermogenesis. The authors have done a good job of textually editing their manuscript to clarify the findings and limitations of the study.

     This work describes how the toxin-antitoxin (TA) system, which uses the cyclic di-GMP as an antitoxin, controls both the persistence of antibiotics linked to biofilms and the integrity of the bacterial genome. The authors present solid evidence linking cyclic di-GMP and the toxin HipH. The work is valuable because it establishes the relationship between bacterial persistence and biofilm resilience, which lays a strong basis for future research on the formation of bacterial biofilms and antibiotic resistance.

     The authors provide useful data to support the existence of a regulatory pathway starting with SPI1-driven ZFP36L1 expression, that goes on to downregulate HDAC3 expression at the transcript level, leading to PD-L1 upregulation due to implied enhanced acetylation of its promoter region. This is therefore an interesting pathway that adds to our understanding of how PD-L1 expression is controlled in gastric cancer. However, this is likely one of many possible pathways that impact PD-L1 expression, and the data are currently incomplete to support the claims made.

     This is an important study that connects the polymerase-associated factor 1 complex (Paf1C) with Histone 2B monoubiquitination and the expression of genes key to virulence in Cryptococcus neoformans. The provided information is convincing and has the potential to open several opportunities to further understand the basic biology of this significant human fungal pathogen.

     In this manuscript the authors examine correlations between intrinsic electrophysiological properties of HVC neurons projecting to Area X and the temporal structure of the birds' song. The study provides important insights into how the structure of vocalization can relate to intrinsic physiological properties of the neurons that are essential for learning the behavior. The evidence supporting the idea that song temporal structure is related to intrinsic physiology is solid and this research will be of general interest to researchers in the field and neurophysiologists.

     Giamundo et al. present fundamental data with new insights into the role of Ezrin, a major membrane-actin linker that assembles signaling complexes, in the spatial regulation of EGF signaling mediators. The use of multiple state-of-the-art microscopy techniques, multiple cell lines and inhibitors, together with in vivo models convincingly supports the majority of their conclusions. The findings are helpful for understanding EGF/mTOR signal transduction and support a critical role for the scaffolding protein Ezrin in the upstream regulation of EGFR/AKT activity, TSC subcellular localization and mTORC1 signaling. These findings contribute substantially to understanding how endo-lysosomal signaling are regulated, alterations which are implicated in many human diseases.

      This study reports a fundamental observation concerning cell death regulation by the anti-apoptotic BCL2 family NOXA. The authors convincingly demonstrate that NOXA is destabilized through the interaction with WSB2, a substrate receptor in CRL5 ubiquitin ligase complex, sensitizing the cells to treatments. These are key findings for cell biologists and cancer researchers as they identified a new target impacting drug responsiveness in cancer therapies.
