Figure Lengend Snippet: a Mean fluorescence intensity (MFI) of CXCL8 within FluoroSpot eluates after stimulation with either S1 or S2 spike peptides from SARS-CoV-2 or OC43 and HKU1 compared to DMSO control. Donors were SARS-CoV-2 vaccinated donors and >65 years of age ( n = 15). Kruskal–Wallis (uncorrected Dunn’s test). Black lines indicate the median MFI with interquartile range. b Mean fluorescence intensity (MFI) of CXCL10, TNFɑ, IFN-ɑ2, IL-7 and IL-10 within FluoroSpot eluates after stimulation with SARS-CoV-2 S1 or S2 peptides compared to a DMSO control in vaccinated donors over the age of 65 ( n = 15). Kruskal–Wallis (uncorrected Dunn’s test). Black lines indicate the median MFI with interquartile range. Source data: Supplementary Data .

Figure Lengend Snippet: (A) IF of (PR) 97 HA (red) and FBL (green), in liver sections from littermate PR +/+ and PR KI/KI mice, 3 weeks after treatment with dox in the drinking water. Scale bar (white) represents 10 μm. (B) Quantification of nucleolar FBL+ area from the images shown in (A). (C) GSEA enrichment plots for the “cytoplasmic r-proteins” class from RNA-seq data comparing liver RNA from PR +/+ and PR KI/+ littermates after 17 weeks of treatment with dox. (D) Normalised read counts of all detected r-protein mRNAs, quantified by RNA-seq in total RNA of livers from non-inducible (grey, PR +/+ ) and inducible (blue, PR KI/+ ) littermates, after 17 weeks of treatment with dox. (E) WB evaluating the levels of mTOR signalling (pRPS6), and of total RPS6 and RPS2 levels in livers from non-inducible PR +/+ and inducible PR KI/+ littermates after 20 weeks of treatment with dox. (F) RPS6 and pRPS6 IHC in liver sections from a non-inducible mouse (PR +/+ ) and an inducible littermate (PR KI/KI ), after 3 weeks of treatment with dox. (F) Diagram illustrating the experimental pipeline for the treatment of PR +/+ and PR KI/KI animals with rapamycin and dox. (G) Kaplan-Meyer representation of the lifespan of non-inducible PR +/+ ( n = 13), and inducible PR KI/KI ( n = 13) littermates. Animals started treatment with rapamycin in their diet at week 9, and the treatment with dox started on the following week. Note that rapamycin extends the median lifespan by 60% in inducible mice.
