Article Title: Cholesterol-rich lipid rafts mediate endocytosis as a common pathway for respiratory syncytial virus entry into different host cells

doi: 10.1128/spectrum.01192-25

Figure Lengend Snippet: RSV entry into cells triggers actin polymerization and endosome formation by cholesterol-rich lipid rafts. ( A ) RSV enters cells by actin-mediated endocytosis. HEp-2 or A549 cells were infected with RSV A2 (MOI = 30) (90 min, 37°C) and fixed (4% PFA, 15 min, room temperature). Cell nuclei were labeled with DAPI (cyan), lipid rafts with Alexa 647-CTB (blue), cholesterol with NBD-cholesterol (green), and F-actin with CellMask orange actin tracking dye (yellow), and images were acquired using confocal microscopy. Scale bar = 10 µm. Intensity profiles show colocalization along the direction of the yellow line. Pearson’s correlation between lipid rafts, cholesterol or F-actin, and RSV. n = 16 cells per group. Error bars represent a 95% confidence interval. ( B ) RSV trafficking from early to late endosomes. HEp-2 or A549 cells were infected with RSV A2 (MOI = 30) (150 min, 37°C) and fixed. Cell nuclei were labeled with DAPI (cyan), lipid rafts with Alexa 647-CTB (blue), and cholesterol with NBD-cholesterol (green). Immunodetection of RSV F (blue), RSV-FITC (green), EEA1, Rab7, and STX 6 (red) was performed using confocal microscopy. Scale bar = 10 µm. Intensity profiles show colocalization along the direction of the yellow line. Pearson’s correlation between lipid rafts, cholesterol or F-actin, and RSV. n = 16 cells per group. Error bars represent a 95% confidence interval.

Article Title: A Novel TRPC6 Mutation Causes Autosomal Dominant FSGS

doi: 10.1101/2025.02.11.637765

Figure Lengend Snippet: iPS-cell derived podocytes have reduced expression of slit diaphragm proteins, ER congestion, and reduced lysosomes. Panel A shows representative immunoblots of podocyte markers including Nephrin, Synaptopodin, TRPC6, Podocin, CD2AP, GLEPP1, and WT1, the housekeeping protein GAPDH. Panel B shows the quantification of immunoblots for the podocyte markers. Data represents three biologically independent experiments and is defined as ± standard error of the mean. We performed one-way ANOVA with Dunnett’s multiple comparison post hoc analyses with a family-wise alpha threshold of 0.05. Panel C shows electron micrograph of differentiated podocytes with protein aggresomes in the ER of Duke 5 and Duke 7 podocytes. Panel D shows LAMP1 vesicles, Podocin, and TRPC6 expression in podocytes. The LAMP1 vesicle number remains unchanged in the podocytes. Panel E shows lysosomal biogenesis-associated RAB7 expression in the podocytes. RAB7 expression was reduced in the mutants. Data is representative of three biologically independent experiments and the data is defined as ± standard error of the mean. We performed one-way ANOVA with Sidak’s multiple comparison post hoc analyses with a family-wise alpha threshold of 0.05. Scale bar: Panel C, top row 1000 µm, bottom row 500 nm; Panel D, top row 20 µm, bottom row 5 µm; Panel E, 100 µm.
