Bacterial Indole-3-Lactic Acid Affects Epithelium–Macrophage Crosstalk to Regulate Intestinal Homeostasis

[Proceedings Of The National Academy Of Sciences Of The United States Of America] Escherichia coli strain and indole-3-lactic acid contributed to the relief of colitis by inhibiting the production of epithelial CCL2/7, thereby reducing the accumulation of inflammatory macrophages in vitro and in vivo.

E-Selectin-Mediated Rapid NLRP3 Inflammasome Activation Regulates S100A8/S100A9 Release from Neutrophils via Transient Gasdermin D Pore Formation

[Nature Immunology] Mechanistically, E-selectin engagement triggered Bruton’s tyrosine kinase-dependent tyrosine phosphorylation of NLRP3.

Selective Control of Transposable Element Expression during T Cell Exhaustion and Anti–PD-1 Treatment

[Science Immunology] Researchers used bulk and single-cell transcriptomics to analyze expression of transposable elements in subpopulations of mouse and human CD8+ tumor-infiltrating T lymphocytes.

A Mechanosensitive Caveolae–Invadosome Interplay Drives Matrix Remodelling for Cancer Cell Invasion

[Nature Cell Biology] Scientists described a unique juxtaposition of caveola clusters and matrix degradative invadosomes at contact sites between the plasma membrane of cancer cells and constricting fibrils both in 2D and 3D type I collagen matrix environments.

Ikaros Is a Principal Regulator of Aire+ mTEC Homeostasis, Thymic Mimetic Cell Diversity, and Central Tolerance

[Science Immunology] Thymic epithelial cell (TEC)-specific deletion of Ikzf1 in mice resulted in a profound decrease in Aire+ medullary TECs, a global loss of tissue-specific antigengene expression, and the development of autoimmunity.

Preclinical Long-Term Safety of Intraspinal Transplantation of Human Dorsal Spinal GABA Neural Progenitor Cells

[iScience] Investigators characterized the long-term fate and safety of human dorsal spinal γ-aminobutyric acid (GABA) neural progenitor cells (NPCs) in naïve rats over one year. All grafted NPCs had undergone differentiation, yielding mainly neurons and astrocytes.
