     This study reports the relative importance of Tie1 and Tie2 signaling for atrial versus ventricular trabeculation. It is an important study and is one of the few works to date that have carefully and simultaneously analyzed these two processes. In line with a previous study in zebrafish, the authors demonstrate key differences between atrial and ventricular trabeculation. While the imaging and quantitative analyses are conducted using solid and validated methodologies throughout the manuscript, future studies using additional experimental approaches will be invaluable to further establish the underlying mechanisms.

     This study reports a novel function for syntaxin 11, a specialized SNARE protein critical for the immune system whose mutations cause familial hemophagocytic lymphohistiocytosis type 4. The data convincingly show that depletion of STX11 impairs store-operated calcium entry in Jurkat T cells and that this defect is recapitulated in primary cells from a patient suffering from the disease; the authors further show that the syntaxin interacts with the pore subunit of the ORAI1 channel and propose that it primes the channel by promoting the assembly of multimers before activation by its endogenous ligand, the ER Ca2+ sensing protein STIM1. This is a conceptually important claim that challenges the prevailing view that all structural transitions in ORAI1 are STIM-driven. The high-quality data strongly support the interpretations, but the discussion would be strengthened if the authors suggest alternative mechanisms and mention earlier studies reporting ORAI1 regulation by vesicular trafficking.

     This important study provides detailed insights into the metabolic states of hemocyte populations across developmental stages and in both physiological and pathological contexts, including during immune challenge. The study provides convincing evidence by comparing the relative utilization of glycolysis and oxidative phosphorylation in Drosophila larval immune cells, and can have implications for metabolic programs that shape immune function in health and disease.

     This valuable study demonstrates that a multi-step differentiation program in bacteria combining a bistable switch with two quorum-sensing systems is capable of generating autonomous and self-organized spatial patterns. The evidence for the core engineering system using fluorescent reporters support patterning across several conditions is convincing and has significant implications on the process of cell differentiation.

     This important study combines single-molecule imaging and CUT&TAG to address the molecular mechanism underlying the differentiation process that initiates the formation of red blood cells in the bone marrow. The authors provide evidence that the transcription factor GATA2 transiently associates with a new set of genomic loci early in the differentiation process before it is replaced by GATA1. Together, the experiments across three biological systems are solid, but they could benefit from additional details and controls to strengthen the conclusions.

     This study provides fundamental insights by demonstrating that the Nanog mRNA coding sequence (CDS) and 3′UTR domains are spatially segregated and functionally distinct in pluripotent stem cells and blastocysts, with 3′UTR-enriched border cells primarily influencing morphogenesis and CDS-enriched inner cells largely regulating transcription and epigenetic programs. The work opens a novel conceptual avenue for understanding how separable mRNA domains can differentially control cell behavior and differentiation. However, the evidence is incomplete, as key aspects of the molecular nature, biogenesis, and precise characterization of the separated 3′UTR and CDS RNA species, as well as causal links between their perturbation and the observed phenotypes (e.g., via rescue and deeper characterization of 3′UTR elements), remain to be fully established.

     The authors propose a "simplified" model for intrinsically bursting neurons with explicitly controllable parameterization of oscillatory dynamics. The evidence that the modeling approach is generally appropriate and practical for modeling rhythmic bursting neurons and neural circuits is currently incomplete. Based on what the authors present, this model appears to have limited neurobiological relevance and utility but may be useful as a controller for an artificial system, such as in neuro-robotics applications.

     There is a need for better and safer dengue virus live attenuated vaccines. This manuscript describes important findings that could lead to the design of a strongly immunogenic, tetravalent live attenuated vaccine for dengue, without the risk of causing antibody-dependent enhancement. However, the experimental evidence presented is incomplete since only constructions of one serotype were tested to prove the principle.

     This study presents important findings linking peripheral inflammation to the remodeling of perinodal adipose tissue and draining lymph nodes, suggesting a mechanism by which local tissue inflammation can reshape LN structure and metabolism. The evidence is solid and supported by observations, future studies will address any outstanding questions.

      This is a useful study investigating the role of peristalsis in the elongation of the gut, using the chick ceca as a model. The work employs optogenetics together with embryological approaches to establish links between peristaltic muscle contractions and downstream cell behaviors that lead to tube elongation. However, the work is somewhat incomplete, limited in mechanistic insights that would extend beyond prior work in the literature, which has already suggested a role for smooth muscle contractility in avian gut elongation.
