Stromal‐Derived IL‐8 Promotes M2 Macrophage Polarization via the RhoA/MRTF‐A/SRF Transcriptional Axis to Impair CD8+ T Cell Cytotoxicity in Lung Cancer

Advanced Science, EarlyView.
In the recondite pulmonary neoplastic milieu, DESMIN+ cancer‐associated fibroblasts function as the paramount stromal source of IL‐8, precipitating a deleterious immunological metamorphosis by engaging CXCR2 receptors on the myeloid lineage. This paracrine stimulus triggers a mechanotransduction cascade characterized by RhoA‐dependent actin ...

Characteristics of the Preliminary Breakdown in Inverted-polarity Intracloud Lightning Flashes

应用气象学报, 2023
The intracloud (IC) flashes can be classified into normal and inverted-polarity types according to their initial leader propagation directions. Due to the rare occurrence of inverted-polarity IC flashes with downward preliminary breakdown (PB) processes,
