Figure Lengend Snippet: a RAG1 −/− -mice were subjected to photothrombotic stroke, received different subsets of T cells or vehicle (veh), and were then subjected to running wheel training. b Running wheel training did not influence the asymmetry index in the adhesive tape removal test ( p = 0.46, two-sided t -test, n = 6 and 5 animals per group) in RAG1 −/− -mice without adoptive T cell-transfer (ex = exercise, no ex = no exercise). c Adoptive transfer of CD3 + T cells, in the absence of exercise, did not enhance recovery in RAG1 − / − mice ( p = 0.28, two-sided t -test, n = 8 and 8 animals per group). d Following adoptive CD3 + -T cells-transfer, exercise led to a significantly reduced asymmetry index (*** p = 0.0002, two-sided t -test, n = 13 and 12 animals per group), indicating improved functional outcome. e There was a strong trend towards better functional outcome after CD4 + - compared to CD8 + -T cell-transfer ( p = 0.07, two-sided t -test, n = 7 and 11 animals per group). f The transfer of FoxP3 + regulatory T cells (Tregs) resulted in significantly better functional outcomes than the transfer of FoxP3 - nonregulatory T cells (*** p = 0.0009, two-sided t -test, n = 6 and 10 animals per group). g Preventing leukocytes from entering the brain by inhibition of very late antigen-4 (VLA-4) impaired stroke recovery (* p = 0.02, two-sided t -test, n = 7 animals per group; iso = isotype antibody). h MRI-DTI fiber tracking demonstrated an increased number of interhemispheric connections in mice that received Tregs before running wheel training compared to mice that received only vehicle and running wheel training (** p = 0.0013, two-sided t -test, n = 9 and 10 animals per group). Exemplary scans of animals with a high (ex) and a low (no ex) number of interhemispheric connections. For box and whisker plots, the box extends from the 25th to the 75th percentile, the center is the median and whiskers extend from the minimum or maximum.

Figure Lengend Snippet: a Quantification of immune cells by flow cytometry 14 days after stroke revealed that exercise significantly reduced brain-infiltrating CD45 high immune cells and CD3 + T cells (* p = 0.04 and ** p = 0.002, two-sided t -test, n = 7–9 animals per group), but had no impact on the count of CD45 high immune cells and CD3 + T cells in cervical lymph nodes (cLN) and spleen. b Exercise did not influence the proportions of CD4 + - and CD8 + -T cells in brain parenchyma, cervical lymph nodes and spleen 14 days after photothrombotic stroke (two-sided t -test, n = 9–12 animals per group). c Exercise increased the proportion of CD25 + CD4 + -and FoxP3 + CD4 + -regulatory T cells in brain parenchyma (* p = 0.04 and p = 0.1, two-sided t -test, n = 9–12 animals per group) and cervical lymph nodes (* p = 0.01, Mann-Whitney-test and ** p = 0.01, two-sided t -test, n = 9–12 animals per group). d The expression of integrin CD49d, which facilitates leukocyte-trafficking into the brain, was upregulated in brain CD4 + -T cells after exercise (* p = 0.03, Mann-Whitney-test, n = 9–12 animals per group), but not in CD4 + -T cells isolated from cervical lymph nodes or spleen. The expression of the activation markers CD69 and CD11a on CD4 + -T cells did not differ in any of the examined compartments. e Exercise led to a significant increase in the proliferation of FoxP3 + CD4+ regulatory T cells (Tregs) in the brain (* p = 0.04, two-sided t -test, n = 4–5 animals per group). Conversely, the proliferation of FoxP3-CD4 + and CD8 + effector T cells exhibited impairment both in the brain (* p = 0.03, two-sided t -test, n = 4–5 animals per group) and cervical lymph nodes (cLN) (* p = 0.03; ** p = 0.006, two-sided t -test, n = 5–6 animals per group) as determined by Ki67 expression. For box and whisker plots, the box extends from the 25th to the 75th percentile, the center is the median and whiskers extend from the minimum or maximum.

Figure Lengend Snippet: a Heatmaps based on immunohistochemical CD3-staining did not reveal apparent differences in the spatial distribution of immigrating CD3 + -T cells between trained and untrained animals. Quantification of CD3 + -T cells in different areas of interest in lesioned cortex, Thalamus and internal capsule 14 or 49 days after ischemia did not show differences in the cell count (two-sided t -test, n = 4–8 animals per group). b – d Representative images of immunohistochemical stainings from the infarct area and the internal capsule; similar results were observed in all animals analyzed ( n = 28 across all groups). e To visualize immigrating FoxP3 + -regulatory T cells in the brain parenchyma, we employed genetically modified FoxP3 + -RFP-mice, in which FoxP3 + -cells are labeled with the red fluorescent protein and can thus be detected by fluorescence microscopy. Heatmaps based on fluorescence microscopy did not reveal apparent exercise effects on the spatial distribution of immigrating FoxP3 + -regulatory T cells in the brain parenchyma ( n = 4 and 5 animals per group). f Volcano plot analysis of RT² profiler displays differential gene expression in mice with or without exercise 14 days after experimental stroke. Each data point represents a transcript, with the abscissa displaying log2 fold change and the ordinate statistical significance (negative log10 p value). Data are generated from 8 wildtype mice (no exercise n = 4; exercise n = 4, two-sided t -test). For box and whisker plots, the box extends from the 25th to the 75th percentile, the center is the median and whiskers extend from the minimum or maximum. Each dot represents an individual biological replicate. Asterisks indicate levels of statistical significance: * p < 0.05. Source data are provided as a file.

Figure Lengend Snippet: Increase of IL-18–producing F4/80-positive macrophages, but not CD3+ T cells, in bronchoalveolar lavage fluid (BALF) from bleomycin-treated, WT B6 mice. Recovered BALF cells were isolated from WT B6 mice treated intraperitoneally with bleomycin or control PBS on Day 4. Isolated BALF cells were stained with PE-Cy7–conjugated anti-mCD3 and PE-F4/80 mAb in the presence of anti-mCD16/CD32 mAb. The cells were then fixed, permeabilized, and stained with FITC anti–mIL-18 (M5). Three-color analysis was performed for analysis of cytoplasmic IL-18 expression in F4/80+ neutrophils and CD3+ T cells.

Figure Lengend Snippet: Gating strategy for T cells and expected results (A and B) The gating strategy of B cells, non-αβ T cells, CD8 + T cells, CD4 + T cells and its subpopulations. First, roughly gate on lymphocytes based on FSC and SSC, and exclude doublets by FSC-A/FSC-H and SSC-A/SSC-H. Then, exclude dead cells by gating on the AmCyan-low population. Next, gate on the CD45-positive cells for pan-leukocytes, then gate on CD3ε and TCRβ to differentiate αβ T cells from non-T cells and non-αβ T cells (γδ T cells). By gating on CD3ε + TCRβ - cells, RORγ-expressing γδ T cells can also be defined. Among non-T cells, B cells can be defined by gating on the CD19-positive population. After gating on αβ T cells, either CD4 + or CD8 + T cells can be determined. Lastly, among CD4-positive T cells, IL-17A + IFNγ + cells and RORγ + FoxP3 + cells can be defined. Potential results from colon (A) and ileum (B). Note: We used the same fluorophore for CD8a and CD19 because we can differentiate CD8 T cells by gating on TCRβ, CD3ε-positive and CD8a (BV605), and B cells on TCRβ, CD3ε-negative, and CD19-positive (BV605).
