    MC38-bearing young or aged mice were treated with anti–PD-L1 Ab. ( A – C ) Lung-infiltrating CD45 + cells were isolated from MC38-bearing young or aged mice that were treated with anti–PD-L1 Ab, and then were analyzed by scRNA-seq. Cluster analysis was performed and plotted by UMAP dimensionality reduction. Subclustering was performed on the data from the Cd4 + T cell populations in young and aged mice, and lower bar plots in A indicate their frequencies. Dot plots shown in B represent the expression of canonical marker genes across the indicated Cd4 + subclusters. Relative expression of indicated genes across subclustered populations from young and aged mice are shown in C . ( D ) Representative images of DAPI staining (left) and in situ RNA hybridization (right; white, <t>ICOS;</t> red, CD19; green, CD4) in lung from aged mice are shown. Scale bars: 100 μm (left) and 50 μm (right). ( E ) Representative dot plots of CD45 iv- cell populations within the lungs are shown. ( F ) Frequencies of indicated lung-infiltrating CD45 – cell populations were assessed in mice treated with indicated Abs. Data are represented as mean ± SEM. * P < 0.05, ** P < 0.01, *** P < 0.001 by 1-way ANOVA followed by Tukey-Kramer post hoc test.

( C ) Changes in the frequency of ICOS + CD4 + T cells in patients with indicated irAEs are shown. “Others” includes symptoms with infusion reaction, fever, adrenal irAEs, carditis, diarrhea, hypophysitis, and neurologic irAEs. * P < 0.05; ** P < 0.01 by Mann-Whitney U test. ( D ) Univariate (ΔICOS, fold change in CXCL13 or IL-6) and multivariate (ΔICOS plus changes in CXCL13) ROC analyses of the predictive values for pneumonitis development. ( E ) Distribution of indicated values in the combined predictive model for pneumonitis incidence in patients with pneumonitis ( n = 8) or without ( n = 12) irAEs. Adonis test based on the Bray-Curtis distance was used. ( F ) Kaplan-Meier plots of progression-free survival of patients with NSCLC stratified according to the median value of the change in peripheral ICOS + CD4 + T cells are shown. Log-rank (Mantel-Cox) test and univariate Cox proportional hazards analyses were performed.

    Article Snippet: The target mRNA in the tissues was hybridized by incubating in RNAscope buffered Z probes for Icos (Advanced Cell Diagnostics, 552451), Cd4 (Advanced Cell Diagnostics, 406841-C2), and Cd19 (Advanced Cell Diagnostics, 314711-C3) at 40°C for 2 hours.
