Heart Failure Promotes Multimorbidity Through Innate Immune Memory

Heart Failure Promotes Multimorbidity Through Innate Immune Memory

Heart Failure Promotes Multimorbidity through Innate Immune Memory Research Background Despite significant medical advances, the mortality rate of heart failure (HF) remains high, necessitating new therapeutic targets. HF patients often experience acute decompensation and develop comorbidities such as chronic kidney disease and frailty syndrome. Th...

LRIG1 Engages Ligand VISTA and Impairs Tumor-Specific CD8+ T Cell Responses

Interaction and Attenuation of Tumor-Specific CD8+ T Cell Responses by LRIG1 and VISTA Academic Background In recent years, the importance of immune checkpoint inhibitors (ICIs) such as Programmed Cell Death Protein 1 (PD-1) and Cytotoxic T-Lymphocyte Antigen 4 (CTLA-4) has received increasing attention. These inhibitors significantly improve the s...

TREM2 Deficiency Reprograms Intestinal Macrophages and Microbiota to Enhance Anti–PD-1 Tumor Immunotherapy

TREM2 Deficiency Reprograms Gut Macrophages and Microbiota to Enhance Anti-PD-1 Tumor Immunotherapy Background Immune checkpoint inhibitors (CPIs), such as drugs that block programmed cell death protein-1 (PD-1), programmed death-ligand 1 (PD-L1), and cytotoxic T-lymphocyte-associated protein-4 (CTLA-4), have been successfully used to activate anti...

A Lactate-SREBP2 Signaling Axis Drives Tolerogenic Dendritic Cell Maturation and Promotes Cancer Progression

The Tumor Lactate-SREBP2 Signaling Pathway Drives Tolerogenic Dendritic Cell Maturation and Promotes Cancer Progression In recent years, the critical role of dendritic cells (DCs) in antitumor immunity has been widely recognized. However, many cancers cause DC dysfunction through mechanisms that are not fully understood. In a newly published study ...

Reactivating PTEN to Impair Glioma Stem Cells by Inhibiting Cytosolic Iron-Sulfur Assembly

Using the Suppression of Cytoplasmic Iron-Sulfur Cluster Assembly to Restore PTEN and Inhibit Glioma Stem Cells Background Glioblastoma (GBM) is one of the most lethal primary brain tumors. Glioma stem cells (GSCs) not only initiate and sustain the malignant phenotype but also enhance treatment resistance. Although PTEN frequently mutates in gliobl...

Mechanism of SRC Inhibition in IDH-Mutant Cholangiocarcinoma

Scientists Reveal the Anti-Tumor Mechanism of Src Inhibitors in IDH Mutant Cholangiocarcinoma Background Introduction In recent years, the incidence of intrahepatic cholangiocarcinoma (ICC) has been rising worldwide. ICC is a highly invasive tumor usually lacking noticeable symptoms in the early stages, with cases often being inoperable by the time...
