( A ) PCA comparing transcriptomes of unchallenged moDCs (CTRL) with expression profiles of moDCs exposed to CMV IL-10, A. fumigatus (AF), or both (AF + CMV IL-10). ( B ) Venn diagram summarizing shared and condition-specific differentially expressed genes (DEGs) across multiple comparisons. ( C ) Heatmap displaying DEGs in response to single infections with CMV IL-10 or AF, and co-stimulation. Left: DEGs associated with infection response. Right: Selected immune-related DEGs. Significant differential expression against “CTRL” (symbol: +), “AF” (symbol: ⭘), or both “CTRL and AF” (symbol: ⊕) according to DESeq2 analysis (adjusted P ≤ 0.05, log2(|FC|) ≥ 1).

Figure Legend Snippet: Despite differences in antiviral protein secretion, viral CMV IL-10 expression only subtly impacts HCMV-induced suppression of antifungal responses during co-infection. ( A ) Heatmap displaying DEGs in response to single infections with HCMV TB40, Δ UL111A , or A. fumigatus (AF), as well as co-infection with both pathogens. Left: DEGs associated with infection response. Right: Selected immune-related DEGs across six tested conditions. Significance of pairwise comparison against “CTRL” (symbol: +), “AF” (symbol: ⭘), or both “CTRL and AF” (symbol: ⊕) is indicated. ( B ) Comparison of cytokine and chemokine release of uninfected moDCs (CTRL) and those challenged with single infection (TB40, Δ UL111A , AF) or co-infection (AF + TB40, AF + Δ UL111A ) for 9 h. ( A and B ) N = 3 independent donors. ( A ) Statistical significance according to DESeq2 analysis (adjusted P ≤ 0.05, log2(|FC|) ≥ 1). ( B ) Columns and error bars indicate means and standard deviations, respectively. Friedman test with Dunn’s multiple comparisons test versus CTRL (asterisks). In addition, single A. fumigatus infection (AF) was compared to co-infection (AF + TB40, AF + Δ UL111A ) using the Friedman test with Dunn’s multiple comparisons test versus AF (hash signs). */# P < 0.05, **/## P < 0.01.

Figure Legend Snippet: Pre-exposure to HCMV time-dependently weakens antifungal effector responses of moDCs. Relative mRNA expression ( A ) and cytokine secretion ( B ) of moDCs (CTRL) challenged individually with TB40, Δ UL111A , A. fumigatus (TB40, Δ UL111A , AF), or in combination (AF + TB40, AF + Δ UL111A ) for 9 h (labeled “0 h” viral pre-exposure); or pre-exposed for 24 h/ or 72 h to either HCMV variant with or without subsequent challenge with A. fumigatus for another 9 h (labeled as “24 h” or “72 h” viral pre-exposure). N = 4 independent donors. Columns and error bars indicate means and standard deviations, respectively. Repeated-measures (RM) one-way analysis of variance (ANOVA) with Dunnett’s post hoc test ( A ) and Friedman test with Dunn’s multiple comparisons ( B ) versus “CTRL,” that is, uninfected moDCs (asterisks). In addition, single AF infection was compared to co-infection (AF + TB40, AF + Δ UL111A ) using RM 1-way ANOVA and Dunnett’s post hoc test ( A ) and Friedman test with Dunn’s multiple comparisons test ( B ) versus “AF” (hash signs). */# P < 0.05, **/## P < 0.01, ***/### P < 0.001.

Figure Legend Snippet: HCMV disrupts antifungal immune responses largely independent of viral CMV IL-10 expression. ( A ) Pathway enrichment analysis to assess the viral single infection-adjusted effect of HCMV on transcriptional responses against A. fumigatus during co-infection. Immune-related pathways with absolute z-scores ≥ 1 and Benjamini-Hochberg-adjusted P -values < 0.05 are shown. ( B ) Viral single infection-adjusted expression data for selected individual genes associated with pathogen sensing, cytokine and chemokine production, and moDC maturation to assess the effect of HCMV on antifungal responses during co-infection. ( A and B ) Three separate analyses were performed, considering data for both HCMV strains on aggregate (left column), WT (TB40) HCMV only (center column), and the Δ UL111A mutant only (right column).

Figure Legend Snippet: Preincubation of moDCs with HCMV but not with CMV IL-10 diminishes the capacity of moDCs to control fungal growth. ( A ) Left panel: Study design illustrating experimental setup for IncuCyte-based monitoring of fungal growth and branching of co-infection experiments. Right panel: Representative kinetics of A. fumigatus (AF) hyphal elongation during transition from germ tubes to hyphae (7–18 h of culture) when cultured alone (AF only) or in the presence of moDCs (AF + moDCs, CTRL), including moDCs pre-exposed for 72 h to TB40, Δ UL111A , or CMV IL-10. In addition, images from a representative donor are shown. Green overlays indicate hyphal detection by the NeuroTrack algorithm. ( B ) Growth and morphogenesis of AF during co-culture with unchallenged moDCs (CTRL) or moDCs pre-exposed for different periods (0 h, 24 h, and 72 h) to moDCs to TB40, UL111A , or CMV IL-10. Results are normalized to AF only (= 100%). N = 4 independent donors. Columns and error bars indicate means and standard deviations, respectively.
