This important study provides compelling evidence that the low-cost and open-hardware UC2 microscopy framework can be expanded to enable single-molecule localization microscopy. The authors managed to fit the instrumentation and control thereof in a unit that can be placed in a small stage-top-incubator. Together with providing adapted software for data acquisition and data analysis, the UC.STORM setup can rival the capabilities of comparable commercial instruments at a fraction of the costs.

This important study provides insights into how the brain constructs categorical neural representations during a difficult auditory target detection task. Through recordings of simultaneous single-unit activity in primary and secondary auditory areas, compelling evidence is provided that categorical neural representations emerge in a secondary auditory area, i.e., PEG. The study is of interest to neuroscientists and can also potentially shed light on human psychological studies.

This important study provides convincing evidence that emotional information in biological motion can induce different patterns of pupil responses, which could serve as a behavioral marker of an autistic trait. These results broaden our understanding of how emotional biological motion can automatically trigger physiological changes and reveal the potential of using emotional-modulated pupil response to facilitate the diagnosis of social cognitive disorders. The work will be of broad interest to cognitive neuroscience, psychology, affective neuroscience, and vision science.

The authors used an innovative modified 10X genomic sequencing method to detect cPCDHg is-forms in pyramidal neurons. With solid electrophysiological recordings, they showed that neurons expressing the same sets of cPCDHg isoforms are less likely to form synapses with each other. These valuable findings confirms previous results and extend our understanding of cPCDHg diversity and neuronal connectivity.

This study presents an important finding on the anatomical connectivity and functional roles of the previously uncharacterized neuronal populations in the nucleus incertus. The evidence supporting the conclusions is convincing, with imaging and manipulations of the genetically targeted populations of neurons. The work presents a significant milestone for future mechanistic studies of the nucleus incertus.

This study tackles a significant question: Does the brain apply spatial navigation systems to evaluate decision options in conceptual social spaces? The investigation is useful as it seeks to address this intriguing hypothesis. The findings offer partial support: a solid analysis revealed characteristic grid-like patterns associated with decision-making directions. However, it remains uncertain whether these effects are genuinely due to navigating a conceptual social space or potentially confounded by changes in visual stimuli. The experimental design may not be capable of definitively resolving this issue.

The manuscript by Paine and coworkers provides a fundamental improvement on how the enzymatic activity of CALPAIN7 (a Cys protease) influences cytokinesis mediated by the ESCRT (endosomal sorting complexes required for transport) pathway. The authors provide a convincing molecular and cellular basis for one of the several key steps involved in membrane fission during the separation of dividing eukaryotic cells. These findings should be of interest to a wide scientific audience including biochemists, structural biologists, and cell biologists.

eLife assessment

This important work advances our understanding of the generation of a main organizer of the vertebrate brain, the cortical hem. The authors convincingly show the contribution of multiple downstream effectors, each involved in specific processes regulated by the master gene, Lmx1a. This study has broader implications for how secondary organizers are created in the embryo and will be of interest to a wide readership.

eLife assessment

This important study deepens our understanding of macrophage phenotypes in pathological contexts and identifies a new macrophage state associated with tissue fibrosis, as well as putative drivers of this cellular state. The authors provide convincing evidence and performed a well-thought-out and thoroughly described computational analysis of single-cell RNA-sequencing data. This work will be of broad interest to the fields of tissue inflammation, fibrosis, macrophage biology, and immunology.

The manuscript by Salloum and colleagues shows that cholesterol-lowering statins can reduce mitochondrial cholesterol and impact epigenetic programs in macrophages. The findings could be valuable for understanding statin-mediated anti-inflammatory functions in macrophages. The major claims describing new mechanisms by which statins may regulate macrophage function via epigenetic programming are partially supported by the data presented.

This current study provides a new model of lung agenesis to explore the generation of the ability of blastocyst complementation to generate an entire organ. These studies will provide new avenues for organ bioengineering and additional insight into early contribution of mesoendoderm to lung development.

In this study, Yang et al. have shown that SIRT2 has adverse effects on the heart in response to injury. Further, they demonstrate that deletion of Sirt2 is protective through stabilization and increased nuclear translocation of NRF2, which leads to increased expression of antioxidant genes. They also show that pharmacological inhibition of SIRT2 protects the heart against the development of cardiac hypertrophy.

eLife assessment

The authors attempted to show that syntaxin 6 (Stx6) delays PrP fibril formation and in presence of Stx6, PrP forms amorphous aggregates which are more toxic to neuronal cells, indicative of Stx6's anti-chaperone activity. This useful study has potential to provide important understanding of the molecular mechanism of PrP aggregation and neurotoxicity. However, the evidence supporting the physiological relevance and robustness of the assays is incomplete.

Plant intracellular ion channels are poorly understood. In this important manuscript, patch-clamp is used to define functional differences between two cation channels present in the vacuole of different plants. The authors find a calcium-biding site whose absence or presence modulate activation at lower voltages and is responsible for increased excitability in the vacuole of the faba bean plant. The experimental evidence presented is convincing and findings have practical implications for the field of plant electrophysiology and channel biophysics.

eLife assessment

This is an important study that investigates the role of commensal microbes and molecules in the antigen presentation pathway affecting the development and phenotype of an unusual population of T lymphocytes. The authors provide compelling evidence to identify a population of unconventional T cells that exist in the small intestinal epithelium, which appear to depend on commensal microbes, and show that a single commensal microbe (that encodes an antigen capable of weakly stimulating these cells) is sufficient to maintain this T cell population.

eLife assessment

This valuable study describes mice with a knock out of the IQ motif-containing H (IQCH) gene, to model a human loss-of-function mutation in IQCH associated with male sterility. While the evidence for interaction between IQCH and potential RNA binding proteins is limited, the human infertility is reproduced in the mouse, making it a compelling model. The paper could be of interest to cell biologists and male reproductive biologists working on the sperm flagellar cytoskeleton and mitochondrial structure.
