Genome-Wide Screening Identifies TRIM33 as an Essential Regulator of Dendritic Cell Differentiation

Genome-wide screening identifies TRIM33 as an essential regulator of dendritic cell differentiation Background Dendritic cells (DCs) serve as a bridge between innate and adaptive immunity by recognizing pathogens through pattern recognition receptors (such as TLRs) and modulating antigen-specific T cell responses. DCs are mainly divided into two ty...

TH17-Intrinsic IL-1β–STAT5 Axis Drives Steroid Resistance in Autoimmune Neuroinflammation

TH17-Intrinsic IL-1β–STAT5 Axis Drives Steroid Resistance in Autoimmune Neuroinflammation

TH17 Endogenous IL-1β–STAT5 Axis Drives Steroid Resistance in Autoimmune Neuroinflammation Academic Background Steroid resistance is a major challenge in managing various inflammatory diseases, including autoimmune neuroinflammation. T helper 17 (TH17) cells are widely believed to be associated with steroid resistance. However, the specific mechani...

Nucleobase Adducts Bind MR1 and Stimulate MR1-Restricted T Cells

Nucleotide Adduct Binding MR1 and Activation of MR1-Restricted T Cells Academic Background MR1T cells, a recently discovered class of T cells, can recognize antigens presented by MHC class I-related molecule MR1 without microbial infection. These cells exhibit both helper and cytotoxic properties in vitro, but the endogenous antigens they recognize...

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 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...

mRNA-LNP Prime Boost Evolves Precursors Toward VRC01-Like Broadly Neutralizing Antibodies in Preclinical Humanized Mouse Models

Inducing and Optimizing VRC01-like Broadly Neutralizing Antibodies in Mouse Models with mRNA-LNP Background Introduction In recent years, the importance of acquiring broadly neutralizing antibodies (bnAbs) has been increasingly recognized in vaccine development, particularly in the field of HIV (Human Immunodeficiency Virus) vaccine research. The H...

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 ...

Intratumoral Antigen Signaling Traps CD8+ T Cells to Confine Exhaustion to the Tumor Site

Intratumoral Antigen Signaling Traps CD8+ T Cells to Confine Exhaustion to the Tumor Site

Research Progress in Cancer Immunology: Tumor-derived Antigen Signals Induce CD8+ T-cell Exhaustion Localized to the Tumor Site Research Background and Purpose In recent years, immunotherapy has shown great potential in cancer treatment. However, tracking the behavior of immune cells after receiving antigen signals remains a challenge. Within tumor...

TDRD3-null Mice Show Post-Transcriptional and Behavioral Impairments Associated with Neurogenesis and Synaptic Plasticity

TDRD3 Deficient Mice Exhibit Deficits in Neurogenesis and Synaptic Plasticity at Both Post-transcriptional and Behavioral Levels Research Background Topoisomerase 3b (top3b) is a dual-activity topoisomerase capable of resolving DNA and RNA topological problems. An increasing body of evidence indicates that top3b functions as a conserved complex wit...
