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 ...

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...

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...

Redefining the ontogeny of hyalocytes as yolk sac-derived tissue-resident macrophages of the vitreous body

The purpose of this paper is to explore the developmental origin, biological characteristics, and association with eye diseases of tissue-resident macrophages in the field of ophthalmology—hyalocytes. The eye is a highly specialized sensory organ that contains the retina, part of the central nervous system, as well as non-neuronal parts like the tr...

Morphotype-Specific Calcium Signaling in Human Microglia

Morphology-Specific Calcium Signaling Characteristics in Human Microglia Background and Research Objectives Microglia are the primary immune cells of the central nervous system (CNS), involved in almost all physiological and pathological processes, including development, synaptic transmission, neuroplasticity, sleep, trauma, glioblastoma, and neuro...

Inflammatory Mechanisms in Traumatic Brain Injury and Post-Traumatic Epilepsy: A Study

Neuroinflammation and Epilepsy: The Role of Inflammasomes in Traumatic Brain Injury Background and Purpose Traumatic Brain Injury (TBI) refers to changes in brain function and pathology resulting from physical trauma to the head or neck. Apart from common behavioral and psychological disorders, post-traumatic epilepsy (PTE) is one of the most sever...

The impact of high-fat diet on microglial cells and its effects on brain function

Research on Saturated Fatty Acids and Brain Function Background Introduction Obesity and metabolic syndrome are major global health challenges today. Numerous studies have shown that excessive consumption of diets rich in saturated fats leads to obesity, accompanied by a series of metabolic complications such as insulin resistance and diabetes. How...
