4-1BB-encoding CAR causes cell death via sequestration of the ubiquitin-modifying enzyme A20

Background Introduction Chimeric antigen receptor T cells (CAR-T cells) have shown great potential in immunotherapy for certain hematological malignancies. However, how the CD28 and 4-1BB costimulatory domains included in CAR molecules function in CAR-T cells is still not fully understood. Both CD28 and 4-1BB domains exhibit significantly different...

Targeting the Intestinal Circadian Clock by Meal Timing Ameliorates Gastrointestinal Inflammation

Research on Alleviating Gastrointestinal Inflammation by Adjusting Intestinal Circadian Rhythm through Feeding Time Background Information Impaired expression of intestinal circadian rhythm genes has been observed in biopsies from patients with inflammatory bowel disease (IBD). Disruption of circadian rhythms, such as that occurring in shift worker...

Exportin 1 governs the immunosuppressive functions of myeloid-derived suppressor cells in tumors through Erk1/2 nuclear export

Paper Report Research Background Myeloid-Derived Suppressor Cells (MDSCs) are a major driving force in tumor immune suppression. Understanding their mechanisms can provide new therapeutic targets to improve anti-tumor immunity, as the development and immunosuppressive function of these cells directly affect anti-tumor immune responses. In preclinic...

Depleting Profibrotic Macrophages Using Bioactivated In Vivo Assembly Peptides Ameliorates Kidney Fibrosis

Preface Chronic Kidney Disease (CKD) is a condition characterized by long-term damage to kidney structure, leading to gradual loss of kidney function. Currently, about 10% of adults worldwide are affected by CKD, causing approximately 1.2 million deaths annually. Renal fibrosis is one of the pathological manifestations of CKD, characterized by the ...

Neutrophil-derived PAD4 induces citrullination of CKMT1 exacerbates mucosal inflammation in inflammatory bowel disease

In recent years, increasing evidence from research on Inflammatory Bowel Disease (IBD) has shown that neutrophils play a crucial role in the occurrence and development of intestinal inflammation. IBD includes Crohn’s Disease (CD) and Ulcerative Colitis (UC), and while its pathogenesis is not yet fully understood, abnormal immune responses are clear...

Mechanistic Study on SENP6 Regulation of IFN-I Signaling Pathway and Antiviral Activity

Academic Background and Research Question In antiviral efficacy research, type I interferon (IFN-I) has been widely used clinically due to its broad-spectrum antiviral properties. However, the specific signaling mechanism and regulatory modes of IFN-I remain complex and not fully elucidated. In light of this, experts have begun to pay attention to ...

Chaperone- and PTM-mediated Activation of IRF1 Tames Radiation-induced Cell Death and the Inflammatory Response

Study on IRF1 Transcriptional Activation Regulation of Radiation-Induced Cell Death and Inflammatory Response under Mutagenic Stress Background Recent multi-omics studies have revealed the key role of structural cells in immune regulation, but the mechanism remains unclear. Based on this, this study mainly explores how the transcriptional activatio...

Synergy of TL1A and IL-18 promotes GM-CSF-dependent thymic granulopoiesis in mice

Background Introduction In acute systemic inflammatory conditions, the immune system undergoes significant changes, typically characterized by increased myeloid cell generation and suppressed lymphocyte production. In the thymus specifically, systemic inflammation leads to acute thymic atrophy and subsequent impairment of T lymphocyte generation. H...

HIF-1α and MIF Enhance Neutrophil-Driven Type 3 Immunity and Chondrogenesis in a Murine Spondyloarthritis Model

Research Background and Research Questions Spondyloarthritis (SpA) is a typical disease characterized by type 3 immune-driven inflammation and new bone formation (NBF). Although previous studies have shown that Macrophage Migration Inhibitory Factor (MIF) plays a key role in the pathogenesis of SpA, its interactions with other molecules and specifi...

Distinct Palmitoylation of FoxP3 Regulates the Function of Regulatory T Cells via Palmitoyltransferases

Unique Foxp3 Palmitoylation Regulates Tregs Function through Palmitoyltransferases Regulatory T cells (Tregs) play a crucial role in maintaining immune homeostasis and preventing excessive immune responses. As important suppressors of immune reactions, Tregs help maintain immune tolerance, thereby preventing autoimmune diseases. However, in the tum...
