Figure Lengend Snippet: Intracellular C3aR and C5aR1 analysis. A monolayer of VECs was infected or not (Mock) with the Colonizing strain (Col) or VVC strain (VVC) for 4 h. After incubation, intracellular C3aR ( a ) and C5aR1 ( b ) were analyzed by cytofluorimetric analysis. Data in the graphs show the mean ± SEM of C3aR- and C5aR1-positive cells (cell counts from 8000 live cells) obtained from 4 different experiments. ns—not significant; * p ≤ 0.05.

Figure Lengend Snippet: Activation of complosome in VECs by C. albicans . Differential activation of C3, C3a and C3b ( a ) and C5 and C5a ( b ) and intracellular C3aR and C5aR1 involvement in VECs infected with the Colonizing or VVC-associated strain. Arrows indicate changes in the levels of complement factors and receptors after infection with either the Colonizing strain (left) or the VVC strain (right). Green indicates increased levels and red indicates lower levels as compared to resting levels. Created with BioRender (adapted from King B.C. and Blom A.M., 2024 ).

Figure Lengend Snippet: Impairment of astrocyte insulin signaling and mitochondrial structure after activation of the C3a‐C3aR pathway. (a–c) Western blotting analysis of C3aR and CD11b expression in wild‐type (WT, 6 months old) and C3 +/+ mice (6 months old) ( n = 4 WT, n = 5 C3 +/+ ; unpaired Student's t ‐test). (d) ELISA analysis of C3a levels in brain tissue from WT ( n = 5) and C3 transgenic mice ( n = 5) (unpaired Student's t ‐test). (e, f) CCK‐8 assay of U251 cell survival after C3a (200 nM) and C3a + SB290157 treatments ( n = 6 per group; unpaired Student's t ‐test). (g) qPCR analysis of insulin receptor (IR) mRNA levels in U251 cells after C3a treatment ( n = 4 per group; unpaired Student's t ‐test). (h–j) Western blotting analysis of IR protein expression in U251 cells after C3a (200 nM) ( n = 7 per group ) and C3a + SB290157 treatments ( n = 5 per group; unpaired Student's t ‐test). (k–m) qPCR analysis of mitochondrial function‐related genes in U251 cells ( n = 4 per group; unpaired Student's t ‐test). (n) Quantitative analysis of mitochondrial area (unpaired Student's t ‐test). (o) Schematic representation of mitochondrial morphology as observed by transmission electron microscopy. (p, q) Measurement of reactive oxygen species (ROS) production in U251 cells: (p) C3a versus vehicle control; (q) C3a + C3aR antagonist (SB290157, 100 nM) versus vehicle control (unpaired Student's t ‐test). All data are presented as mean ± standard deviation (SD).
