doi: 10.64898/2026.03.16.712079
Figure Lengend Snippet: a ) CD4 or CD8 T cells were enriched using AutoMACS selection, lysed and OPA1 presence determined. Shown is a representative Western blot from three biological repeats. b-e ) Memory CD8 T cells were isolated from spleens from YME1L1 f/f littermate controls and YME1L1 ΔTB animals, purified via flow sorting (CD8 + CD44 hi ), and analysed using an electron microscope. b) Representative EM images, were processed to segment mitochondria and cristae respectively, and measurements were made. c) Mitochondrial section area (nm2), d) Mitochondrial section roundness (4π·Area/Perimeter² in arbitrary units (a.u.)) (n=94 controls, n=37 YME1L1 ΔTB ), e) Percentage of branched cristae (n=29 controls, n=9 YME1L1 ΔTB ), f) Cristae Feret diameter (nm), and g) Tortuosity calculated as 1-Feret diameter (FD)/longest shortest path (LSP) (n=371 controls, n=138 YME1L1 ΔTB ). Statistical analysis: Mann-Whitney tests.
Article Snippet: Cell suspensions were incubated with CD4-, CD8- or CD19-APC antibodies (Supplementary Table 1) and subsequently with anti-APC Microbeads (Milteny Biotech), for the isolation of CD4+ or CD8+ T cells or CD19+ B cells, respectively, by the autoMACS Pro Separator (Milteny Biotech).
