Intermanual transfer and the default mode network. In the study by Rezaei and colleagues, participants initially learned a sensorimotor task with their right hand (the initial learning phase). When they later performed the same task with their left hand (the transfer phase), they made fewer errors at first. Rezaei and colleagues found that brain connectivity patterns, especially those linked to the part of the default mode network (the red region), were notably similar during the early stages of the initial learning (green shaded area) and transfer (orange shaded region) phases. The brain image shows the medial surface of the left hemisphere.

A simplified model of immune education. The model developed by Tepekule and colleagues incorporates key inputs such as maternal human milk oligosaccharides (HMOs) and IgA, infant diet, and endogenous IgA produced in the infant gut. These inputs are then modeled within the context of the infant gut lumen, where IgA can mask or neutralize microbial taxa, and HMOs and plant-derived polysaccharides selectively promote different taxa. Model parameters are informed by existing in situ longitudinal IgA-seq data and infant feeding records. The main outputs include the abundance and IgA binding levels of each modeled microbial taxon, allowing for predictions of how variations in inputs (e.g., changes in breastfeeding or diet) shape the developing infant microbiome.

Probabilistic migration events drive transient tissue residency of lymphocytes during homeostasis Tissue-resident lymphocytes form a phenotypically and functionally distinct analog to the corresponding circulatory lymphocyte populations. Residential CD8 T cells, in particular, are identified as having prolonged residence in the tissues and key functions in recall responses at tissue-environmental interfaces, although the dwell time in individual tissues has yet to be resolved. Residential CD4 T cells, regulatory T cells, B cells, and NK cells have been demonstrated to share phenotypic properties with residential CD8 T cells, but the migratory kinetics are even more poorly defined. Here we used probabilistic modelling on a large parabiosis dataset, covering multiple time-points and tissues, to calculate migration kinetics and dwell times of multiple lymphocyte subsets across a diverse set of tissues. Markov chain modelling identified distinct cell type-specific and tissue-specific residency patterns. The liver and gut were prone to prolonged residency compared to other tissue types, and a hierarchy of residency was observed with CD8 T cells and NK cells demonstrating longer residency than CD4 conventional T cells and regulatory T cells, which in turn resided in tissues longer than B cells. With few exceptions, however, average residency was at least an order of magnitude shorter than the life-span of the mouse, indicating a more dynamic form of steady-state tissue residency than usually assumed. Together these data provide a comprehensive model of a pan-tissue shared program in lymphocyte tissue residence, as well as identifying cell type- and organ-specific modification of the migratory kinetics. ### Competing Interest Statement The authors have declared no competing interest.
