摘要：BACKGROUNDJust as single-cell sequencing has revolutionized many fields of biology, spatial omics, in which molecular parameters are measured in situ on intact tissue samples, is set to empower a new generation of scientific discoveries. A plethora of new technologies now enable spatial profiling of gene and protein expression, genetic mutations, epigenetic marks, chromatin structure, and genome organization. Most of these methods trace back to traditional techniques such as immunohistochemist...

摘要：For species to coexist, performance must decline as the density of conspecific individuals increases. Although evidence for such conspecific negative density dependence (CNDD) exists in forests, the within-species spatial repulsion it should produce has rarely been demonstrated in adults. In this study, we show that in comparison to a null model of stochastic birth, death, and limited dispersal, the adults of dozens of tropical forest tree species show strong spatial repulsion, some to surpris...

摘要：In a technical comment, Barron et al. (1) criticized the work of Huang et al. (2) putting the accent on the quantification of dopamine levels via high-performance liquid chromatography (HPLC), yet also including data interpretation through alternative hypotheses aimed at invalidating the original ones proposed by Huang et al. We thank the authors of this technical comment, which allows us to clarify technical aspects of our work that may have been unclear, and for promoting discussion around t...

摘要：A mechanistic understanding of how microbial proteins affect the host could yield deeper insights into gut microbiota-host cross-talk. We developed an enzyme activity-screening platform to investigate how gut microbiota-derived enzymes might influence host physiology. We discovered that dipeptidyl peptidase 4 (DPP4) is expressed by specific bacterial taxa of the microbiota. Microbial DPP4 was able to decrease the active glucagon like peptide-1 (GLP-1) and disrupt glucose metabolism in mice wit...
