Figure Lengend Snippet: Immunological phenotyping of LRRK2-G2019S microglia showed heightened activation and inflammatory profiles. A Representative analysis of mean fluorescence intensity (top) and the quantification (bottom) of activation markers (CD68, HLA-DR, CD80, and CD86) of LRRK2-WT and LRRK2-G2019S microglia. Data are shown as mean ± SD ( n = 3–4), pooled from four independent trials. B Representative analysis of mean fluorescence intensity (left) and the quantification (right) of pathogen recognition receptors TLR2 and TLR4 in LRRK2-WT and LRRK2-G2019S microglia. Data are shown as mean ± SD ( n = 3–4), pooled from four independent trials. C Flow cytometry analysis of microglia phagocytosis in LRRK2-WT and LRRK2-G2019S microglia using fluorescently labelled Zymosan beads. Representative images are shown on the left, quantification on the right. Data are shown as mean ± SD ( n = 3–4), pooled from four independent trials. D Flow cytometry analysis of microglia phagocytosis in LRRK2-WT and LRRK2-G2019S microglia using pH-sensitive fluorescent Zymosan beads. Representative images are shown on the left, quantification on the right. Data are shown as mean ± SD ( n = 3–4), pooled from four independent trials. E Enzyme-linked immunosorbent assay of human inflammatory cytokines in LRRK2-WT and LRRK2-G2019S microglia using the Human Inflammatory Cytokine Multiplex ELISA Kit from Arigo Biolaboratories. Data are shown as mean ± SD ( n = 4), representative of two independent trials. F Flow cytometry analysis of intracellular TNF-α in LRRK2-WT and LRRK2-G2019S microglia upon 24 h stimulation with LPS. Representative images are shown on the left, quantification on the right. Data are shown as mean ± SD ( n = 3–4), pooled from four independent trials. * p < 0.05, ** p < 0.01, *** p < 0.001, **** p < 0.0001
