Recent Advances in Top‐Down Proteomics for Single‐Cell Research
Mass Spectrometry Reviews, EarlyView.ABSTRACT Individual cells have distinctive molecular characteristics, including biologically relevant proteoforms. Although single‐cell (SC) molecular omics offer unprecedented insights into cellular heterogeneity and function, the characterization of proteoforms in SCs remains an uncharted territory.

Small Methods, EarlyView.A multimodal imaging approach combines AFM micro‐indentation and MALDI mass spectrometry imaging on the same fresh‐frozen human meniscus section to directly associate microscale mechanics with molecular composition. Collagen‐rich regions exhibit increased stiffness, whereas zones enriched in other extracellular matrix proteins are mechanically less ...

Spatially resolved mapping of histones reveals selective neuronal response in Rett syndrome
The FEBS Journal, EarlyView.Loss of Mecp2 function is associated with Rett syndrome (RTT). MeCP2 regulates chromatin, yet its influence on histone composition and dynamics is unclear. Combining MALDI‐MSI with LCM–LC–MS/MS, we mapped histone proteoforms across the dentate gyrus, cornu ammonis, and cerebellum in two mouse models of RTT.

Methionine Regulates Antitumour Function of CD8+ T Cells Through Polyamine Synthesis
Immunology, EarlyView.Methionine restriction in vitro enhances CD8+ T cell effector function by suppressing polyamine synthesis and progressively induces the co‐expression of PD‐1 and TIM‐3. Consistently, sustained dietary methionine restriction diminishes the efficacy of adoptive T cell therapy (ACT) and promotes the expression of terminal exhaustion‐associated markers ...
