PSPro Maps Single-Cell Spatial Proteomes
2026-08-13
Mao and colleagues introduce PSPro, a proximity-labeling workflow that captures cell-type-associated proteomes directly from complex tissue slices with sub-micrometer spatial resolution. Its application to pancreatic tumor and spleen tissue demonstrates all-at-once profiling of ten cell types and exposes spatial heterogeneity that is difficult to resolve with conventional region-based proteomics.

Dual-Action Inhibitors Reprogram p38α Dephosphorylation
2026-08-09
The reference preprint shows that selected p38α MAP kinase inhibitors do more than suppress catalytic activity: they stabilize an activation-loop conformation that accelerates dephosphorylation by the phosphatase WIP1. Biochemical assays and X-ray structures connect inhibitor binding, phospho-threonine accessibility, and kinase inactivation, suggesting a route to more durable and selective kinase control.
