Article Title: High Content Image Analysis as a Tool to Morphologically Distinguish Macrophage Activation and Determine Its Importance for Foamy Alveolar Macrophage Responses

doi: 10.3389/fimmu.2021.611280

Figure Lengend Snippet: NR8383 rat macrophage activation status after stimulation with (A) LPS and IFN-γ, (B) IL-4 or (C) IL-4 or IL-4/IL-13. Data are normalized to cell count and presented as mean values ± SEM of three separate experiments. Statistical comparisons are made using a one-way ANOVA analysis with Bonferroni’s multiple comparison post-hoc test. Results are compared to non-polarized control (M0) and statistical significance is marked as follows: * indicates p < 0.01. (C) Representative fluorescent dot (quadrants) plots showing percentage of cells expressing MRC-1 surface receptor.

Figure Lengend Snippet: Morphological characteristic of non-activated, M(LPS+/IFN-γ+) or M(IL-4+) activated NR8383 rat macrophages. Nuclear area (A) , cellular area (B) , number vacuoles per cell (C) , average area of a single vacuole (D) , cellular area occupied by all vacuoles (E) and total area of all vacuoles per cell (F) were quantified in non-activated macrophages (M0), activated with 100 ng/mL LPS and 20 ng/mL IFN-γ [M(LPS+/IFN-γ+)] or activated with 30 ng/mL IL-4 [M(IL-4+)]. Data are presented as mean values ± SEM of three separate experiments. Statistical comparisons are made using a one-way ANOVA analysis with Bonferroni’s multiple comparison post-hoc test. Results are compared to non-polarized control (M0); *** indicates p < 0.001.
