Abstract

Hutchinson–Gilford progeria syndrome (HGPS) causes premature aging in children, with adipose tissue, skin and bone deterioration, and cardiovascular impairment. In HGPS cells and mouse models, high levels of interleukin‐6, an inflammatory cytokine linked to aging processes, have been detected. Here, we show that inhibition of interleukin‐6 activity by tocilizumab, a neutralizing antibody raised against interleukin‐6 receptors, counteracts progeroid features in both HGPS fibroblasts and Lmna G609G / G609G progeroid mice. Tocilizumab treatment limits the accumulation of progerin, the toxic protein produced in HGPS cells, rescues nuclear envelope and chromatin abnormalities, and attenuates the hyperactivated DNA damage response. In vivo administration of tocilizumab reduces aortic lesions and adipose tissue dystrophy, delays the onset of lipodystrophy and kyphosis, avoids motor impairment, and preserves a good quality of life in progeroid mice. This work identifies tocilizumab as a valuable tool in HGPS therapy and, speculatively, in the treatment of a variety of aging‐related disorders.

  • The LmnaG609G mouse model closely resembles human phenotypes, including heightened inflammation markers like IL-6, caspase 1, and Nlrp3, increased oxidative stress, persistent DNA damage, and cell cycle arrest.

    “Among these models, the LmnaG609G mouse model (featuring the mutation 1827C > T; Gly609Gly) closely resembles human phenotypes.305 This includes heightened inflammation markers like IL-6, caspase 1, and Nlrp3, increased oxidative stress, persistent DNA damage, and cell cycle arrest.306,307”

    From Inflammation and aging: signaling pathways and intervention therapies (2023) · cites this paper as [306]

    Citation 305 is attached to the first sentence, not the subsequent list of inflammation and damage markers, which cites 306 and 307. The Materials and Methods (Mice; page unavailable) identifies the Lmna G609G mouse mutation as equivalent to the human HGPS LMNA G608G mutation, and the Results describe HGPS-related disease features in the mice. Our copy does not specify the claimed 1827C>T nucleotide change. (LLM, conf=0.82)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
