Figure Lengend Snippet: Immunofluorescence staining verifies distinct immune archetypes (A) Representative fields selected from tissue section immunofluorescence (IF) staining of patients classified by archetypes (columns), highlighting three major cell types (rows). CTSK marks the OC population, CD4 and FOXP3 double-positive signals indicate CD4 Treg populations, and CD8A and TIM3 double-positive signals represent CD8 Tex populations. (B) Cell counting from IF staining of tissue sections from 21 patients, grouped by archetypes: Mφ-OC ( N = 6 patients), Treg-Tex ( N = 8 patients), and Mono ( N = 7 patients). Three major cell types were analyzed: OC cells were manually counted from entire tissue sections. Treg and Tex populations were quantified from selected fields (regions of interest based on CD4 or CD8A positivity, shown in ). Left: Proportion of OC cells out of total cells; Middle: Proportion of CD4 Tregs out of total CD4 T cells; Right: Proportion of CD8 Tex cells out of total CD8 T cells. (Significance test: One-way ANOVA, ∗ p < 0.05; ∗∗ p < 0.01).
