Purinergic P2X7R expressed on regulatory T cells potentially links molecular mimicry to autoimmune responses

AIMS Allergy and Immunology
The immune system is meant to protect against invading microbes. Although this system is effective against many microbes, some can use molecular mimicry to turn the immune system against the host and activate autoimmune responses.

Immunity to self co-generates regulatory T cells [PDF]

, 2008
Immune responses to self are kept in check by tolerance mechanisms, including suppression by regulatory T cells (Tregs). The defective generation of Tregs specific for self-antigens may lead to autoimmune disease.

HRS Degradation‐Induced Nicotinamide Deficiency in Placental Extracellular Vesicles Triggers Preeclampsia by Disrupting Maternal‐Fetal Immune Homeostasis

Advanced Science, EarlyView.
This study shows that lower NAM levels in PE‐derived pEVs correlate with disease severity. NAM‐deficient pEVs reduce Th1 and Th17 inhibition, leading to PE‐like symptoms. NAM in pEVs inhibits Th1 via SIRT1 and Th17 via macrophages. Reduced NAM in PE‐EVs is due to decreased HRS expression in trophoblasts, resulting from elevated HSP27.

PLA2G16‐Mediated Tetracosatetraenoic Acid Rewires Fatty Acid Oxidation to Impair CD8+ T Cell Immune Function in Promoting Breast Cancer Lung Metastasis

Advanced Science, EarlyView.
Illustrating how tumor‐derived PLA2G16 regulates tetracosatetraenoic acid (C24:4 (n‐6)) accumulation and CD8+ T cell activation via the C24:4‐PPARα‐FAO axis in early metastatic niches, thereby promoting lung metastasis of triple‐negative breast cancer.

Galectin‐1‐Induced Tumor Associated Macrophages Repress Antitumor Immunity in Hepatocellular Carcinoma Through Recruitment of Tregs

Advanced Science
Tumor‐associated macrophages (TAMs) are commonly considered accomplices in tumorigenesis and tumor development. However, the precise mechanism by which tumor cells prompt TAMs to aid in evading immune surveillance remains to be further investigated. Here,

Targeting NRP1 in Endothelial Cells Facilitates the Normalization of Scar Vessels and Prevents Fibrotic Scarring

Advanced Science, EarlyView.
Scars exhibit vascular abnormal alterations, including upregulated NRP1 expression in endothelial cells, increased vascular density and branching, compromised vessel wall integrity, and incomplete pericyte coverage. Therapeutic targeting of NRP1 through hydrogel spray delivery offers a promising approach to normalize aberrant vasculature and prevent ...

Type I Interferon Pathway Activation Disrupts Monocyte Maturation and Enhances Immune Evasion in Multiple Myeloma

Advanced Science, EarlyView.
This study shows that monocytes in multiple myeloma display an excessive interferon response, leading to transcriptional reprogramming and altered differentiation. Using single‐cell sequencing, coculture experiments, and patient samples before and after therapy, the authors demonstrate that induction treatment reduces this interferon response ...

Characterizing Stage‐Specific Cellular Dynamics and Microenvironmental Remodeling in Lung Adenocarcinoma by Single‐Cell RNA Sequencing

Advanced Science, EarlyView.
This study integrated early‐stage patient specimens with publicly available datasets encompassing non‐malignant lung tissues and advanced‐stage LUAD through single‐cell sequencing, revealing a dynamically remodeled tumor microenvironment characterized by a hypoxia‐adapted malignant subset (C5), immunosuppressive LGMN+ macrophages, STAT1‐driven ...
