Extended Data Fig. 5

a. Representative IHC for myeloperoxidase (MPO) from kidneys harvested from 18-month-old Rragc+/+ and RragcS74N/+ male mice. Bars represents 100 μm. b. Representative IHC for myeloperoxidase (MPO) from livers harvested from 18-month-old Rragc+/+ and RragcS74N/+ male mice. Bars represents 100 μm. c. Volcano plot from RNA-seq performed in 6-8-week-old RragcS74N/+ (n = 4) versus 6-8-week-old Rragc+/+ (n = 5) neutrophils isolated from BM. Differential expression was performed with DESeq, using a 0.05 FDR. d. Gene set enrichment analysis (GSEA) related to TFEB target genes, NFKBIA target genes and genes involved in apoptosis in 6-8-week-old RragcS74N/+ (n = 4) versus 6-8-week-old Rragc+/+ (n = 5) neutrophils isolated from BM. e. Quantification of aged neutrophils (CD11b+/Ly6G+/CD62L-/CXCR4+, left) and fresh neutrophils (CD11b+/Ly6G+/CD62L+/CXCR2+, right) by flow cytometry in 2-month-old Rragc+/+ (n = 2) and RragcS74N/+ (n = 3) male mice and in 16-month-old Rragc+/+ (n = 5) and RragcS74N/+ (n = 5) male mice. Statistical significance was calculated by two-way ANOVA. Data are presented as mean values ± SD. f. Experimental setup of the neutrophil adoptive transplant experiment. BM-derived neutrophils were isolated from 10-week-old Rragc+/+ mice (CD45.1.2) and 10-week-old RragcS74N/+ (CD45.2.2) and transplanted at 1:1 ratio to 16-week-old Rragc+/+ (CD45.1.1) hosts. g. Ratio of CD45.2.2/CD45.1.1 transplanted neutrophils in blood, spleen and BM 16 h (n = 3 biological replicates) and 40 h (n = 3 biological replicates) after adoptive transfer as described in f. Data are presented as mean values ± SD. Statistical significance was calculated by two-tailed Student’s t-test. h. Representative images of IF depicting CD45.1 positive cells in kidneys from young male hosts. Bars represent 20 μm. i. Representative images of IF depicting CD45.1 positive cells in kidneys from old male hosts. Bars represent 20 μm.
