Tryptophan 2,3-Dioxygenase-Positive Matrix Fibroblasts Fuel Breast Cancer Lung Metastasis via Kynurenine-Mediated Ferroptosis Resistance of Metastatic Cells and T Cell Dysfunction

Mechanism of Stromal Fibroblasts in Breast Cancer Lung Metastasis Background Introduction Breast cancer is one of the most common cancers among women worldwide, and metastasis is the leading cause of death in breast cancer patients. The lung is one of the most common sites of breast cancer metastasis, yet the mechanisms underlying this process rema...

Local TSH/TSHR Signaling Promotes CD8+ T Cell Exhaustion and Immune Evasion in Colorectal Carcinoma

TSH/TSHR Signaling Promotes CD8+ T Cell Exhaustion and Immune Evasion in Colorectal Cancer Background Colorectal cancer (CRC) is one of the most common malignancies worldwide with high morbidity and mortality rates. Although immune checkpoint blockade (ICB) therapy has shown significant efficacy in some patients, the majority of CRC patients, parti...

Microglia and Macrophages in Glioblastoma: Landscapes and Treatment Directions

Microglia and Macrophages in Glioblastoma Academic Background Glioblastoma (GBM) is the most common primary malignant tumor of the central nervous system, characterized by high invasiveness and lethality. Despite standard treatments such as surgery, chemotherapy, and radiotherapy, the survival rate of patients remains extremely limited, with a medi...

In Vivo Brain Delivery of BBB-Enabled Iduronate 2-Sulfatase in Rats

Delivery of Enzyme Replacement Therapy Across the Blood-Brain Barrier for Hunter Syndrome Background Hunter syndrome (Mucopolysaccharidosis II, MPS II) is a rare inherited metabolic disorder caused by a deficiency of the iduronate-2-sulfatase (IDS) enzyme. This enzyme deficiency leads to the accumulation of glycosaminoglycans (such as heparan sulfa...

Plasma S100β as a Predictor for Pathology and Cognitive Decline in Alzheimer’s Disease

Plasma S100β as a Predictor for Pathology and Cognitive Decline in Alzheimer’s Disease Academic Background Alzheimer’s Disease (AD) is the most common form of dementia, characterized by the deposition of β-amyloid (Aβ) plaques and the aggregation of hyperphosphorylated microtubule-associated protein tau (tau). These pathological changes lead to gra...

A Novel Method to Study CSF Flow and BOLD Coupling Using Real-Time Phase Contrast Interleaved with Cortical BOLD MRI

New Method for Studying the Coupling Between Cerebrospinal Fluid Flow and Cortical BOLD Signals Academic Background In recent years, the role of cerebrospinal fluid (CSF) in brain waste clearance has garnered significant attention. Traditionally, CSF was thought to primarily serve as a cushion and provide immune surveillance. However, growing evide...

Development and Application of an Automated In Vitro Model for Hydrocephalus Research

Application of Automated In Vitro Models in Hydrocephalus Research Background Introduction Hydrocephalus is a neurological condition caused by the accumulation of cerebrospinal fluid (CSF) in the brain’s ventricles. If left untreated, it can lead to severe complications and permanent brain damage. It is estimated that 1 in every 500 newborns is bor...

Numerical Study of the Effects of Minor Structures and Mean Velocity Fields in the Cerebrospinal Fluid Flow

Study on Cerebrospinal Fluid Flow Dynamics and Its Application in Drug Delivery Background Introduction Cerebrospinal fluid (CSF) plays a crucial role in the human spinal canal, responsible for transporting dissolved nutrients and waste products. Due to its pulsatile nature, CSF flow is influenced by cardiac and respiratory cycles. In recent years,...

Brain Endothelial Permeability, Transport, and Flow Assessed Over 10 Orders of Magnitude Using the In Situ Brain Perfusion Technique

Assessment of Brain Endothelial Permeability, Transport, and Flow Background Introduction The blood-brain barrier (BBB) is a critical barrier that protects the brain from harmful substances while also serving as a key obstacle for drug delivery to the brain. The permeability and transport properties of the BBB directly influence the distribution of...

Role of the Transcription Factor Nrf2 in Maintaining the Integrity of the Blood-Brain Barrier

The Role of Nrf2 in Maintaining the Integrity of the Blood-Brain Barrier Academic Background The blood-brain barrier (BBB) is a crucial barrier between the central nervous system (CNS) and the peripheral blood circulation, composed of endothelial cells, pericytes, smooth muscle cells, astrocytes, and neurons. The primary function of the BBB is to s...
