A comprehensive understanding of the evolution of the immune landscape in humans across the entire lifespan at single-cell transcriptional and protein levels, during development, maturation and senescence is currently lacking. We recruited a total of 220 healthy volunteers from the Shanghai Pudong Cohort (NCT05206643), spanning 13 age groups from 0 to over 90 years, and profiled their peripheral immune cells through single-cell RNA-sequencing coupled with single T cell and B cell receptor sequencing, high-throughput mass cytometry, bulk RNA-sequencing and flow cytometry validation experiments. We revealed that T cells were the most strongly affected by age and experienced the most intensive rewiring in cell-cell interactions during specific age.

Background: Genomic data have unveiled a fascinating aspect of the evolutionary past, showing that the mingling of different species through hybridization has left its mark on the histories of numerous life forms. However, the relationship between hybridization events and the origins of cyprinid fishes remains unclear.
Results: In this study, we generated de novo assembled genomes of 8 cyprinid fishes and conducted phylogenetic analyses on 24 species.

Reproductive organs are among the most variable and rapidly evolving structures in the animal kingdom, probably due to sexual selection. In insects, the diverse morphology of male genitalia is often one of the few visible characteristics that can reliably distinguish closely related species, making it crucial for taxonomic classification. Consistent with this, males of the model organism Drosophila melanogaster and its closely related species display remarkable variations in genital morphology.

Background: Preterm infants are at high risk for subsequent neurodevelopmental disability. Early developmental characterization of brain and neurobehavioral function is critical for identifying high-risk infants. This study aimed to elucidate the early evolution of sensorimotor function in preterm neonates by exploring postnatal age-related changes in the brain white matter (WM) and neurobehavioral abilities.

Mucosal-associated invariant T (MAIT) cells are evolutionarily conserved T cells that recognize microbial metabolites. They are abundant in humans and conserved during mammalian evolution, which suggests that they have important nonredundant functions. In this article, we discuss the evolutionary conservation of MAIT cells and describe their original developmental process.
