Human peripheral late/exhausted memory B cells express a senescent-associated secretory phenotype and preferentially utilize metabolic signaling pathways
Abstract
The percentage of late/exhausted memory (LM) B cells increases with age and we show here that this is associated with a lower influenza vaccine response. To identify novel contributors to the phenotypic and functional changes observed in aged B cells, we sorted the major peripheral B cell subsets [naïve, IgM memory, switched memory (swIg) and late/exhausted memory (LM)] and determined their percentages in the peripheral blood as well as their level of immune activation by measuring basal levels of expression of multiple senescence-associated secretory phenotype (SASP) markers, such as pro-inflammatory cytokines (TNF-α/IL-6/IL-8), inflammatory micro-RNAs (miRs, miR-155/16/93), cell cycle regulators (p16 INK4). We found that only memory B cells express SASP markers, and especially the LM B cell subset, which is also showing spontaneous activation of AMP-activated protein kinase (AMPK), the energy sensing enzyme which is ubiquitously expressed in mammalian cells. LM B cells, but not IgM memory B cells, activate a p38MAPK signaling pathway, downstream of AMPK, leading to the expression of SASP mediators, while class switch recombination is downregulated. These data show that some B cell subsets are more inflammatory than others, that they are pre-activated and that this signaling through metabolic pathways is associated with a senescence phenotype, demonstrating for the first time in human B lymphocytes the link between aging, cellular senescence, SASP and metabolism.

“The quality of the humoral immune response declines with age, as aged B cells display a diminished potential to undergo somatic hypermutation154, which could prevent the aged from generating robust neutralizing antibody titers to aid the clearance of natural infection and generate effective immunity against re-infections.”

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.
