PD‐1 Inhibits CD4+ TRM‐Mediated cDC1 Mobilization via Suppressing JAML in Human NSCLC

Advanced Science, EarlyView.
CD4+ tissue‐resident memory T cells (TRMs) in non‐small cell lung cancer recruit conventional type 1 dendritic cells via XCL1‐XCR1 signaling, orchestrating antitumor immunity. The costimulatory molecule JAML is essential for this process. PD‐1 blockade restores JAML expression and cDC1 mobilization, while JAML agonists synergize with anti‐PD‐1 therapy,

Single‐Cell Transcriptome Atlas Reveals the Underlying Mechanism of Kynurenic Acid in the Regulation of Tumor Immune Microenvironment in Glioblastoma

Advanced Science, EarlyView.
KYNA regulates the tumor immune microenvironment in glioblastoma. KYNA reprograms the balance between T cell exhaustion and activation to suppress glioblastoma progression through inhibiting exhaustion‐associated markers (such as PD‐1, LAG3, and TOX) and enhancing immune activation and cytotoxicity markers including granzymes GZMA and GZMB.

Regulating Tumor Metabolic Reprogramming with Biomimetic Co‐Delivery of Simvastatin and Kynureninase for Immunotherapy

Advanced Science, EarlyView.
After the intravenous injection of biomimetic and pH/ROS‐responsive PTSK@CRM, the nanoparticles can be accumulated in tumors and release Sim and KYNase to inhibit the tumor growth, regulate the metabolism of cholesterol and Kyn, and reverse the immunosuppressive tumor microenvironment.

Dysfunctional TRIM31 of POMC Neurons Provokes Hypothalamic Injury and Peripheral Metabolic Disorder under Long‐Term Fine Particulate Matter Exposure

Advanced Science, EarlyView.
Particulate matter ≤2.5 µm (PM2.5) elevates risks of neurological and chronic metabolic diseases, but the underlying mechanisms linking PM2.5‐induced central nervous system (CNS) injury to metabolic dysfunction remain unclear. Hypothalamic pro‐opiomelanocortin‐expressing (POMC+) neurons regulate systemic metabolic homeostasis, and tripartite motif ...

Antigenic: An improved prediction model of protective antigens

Artificial Intelligence in Medicine, 2019
An antigen is a protein capable of triggering an effective immune system response. Protective antigens are the ones that can invoke specific and enhanced adaptive immune response to subsequent exposure to the specific pathogen or related organisms. Such proteins are therefore of immense importance in vaccine preparation and drug design.

Protective Cellular Antigen of Clostridium chauvoei

American Journal of Veterinary Research, 1980
SUMMARY Cellular antigens of Clostridium chauvoei, strain IRP-128, were demonstrated to be important in induction of immunity against this bacterium in guinea pigs. At least one major component of the cellular antigen complex was heat-labile. Acid extraction of the bacterial cells, followed by selective purification for flagella, led to the preparation

Non-CS pre-erythrocytic protective antigens

Immunology Letters, 1990
Three novel non-CS antigens have been identified on P. falciparum and P. berghei sporozoites and exoerythrocytic parasites. CSP-2 is a sporozoite surface protein common to P. falciparum and P. berghei that elicits antibody-mediated protection, and is also found within P. berghei EE parasites. LSA is a P.

Finding Protective Bacterial Antigens

2012
Current vaccine development efforts are mainly focused on opportunistic pathogens that are frequent colonizers and have complex pathogenesis and interaction with the human host. Therefore, more sophisticated and comprehensive vaccine development approaches have to be considered than for strictly pathogenic bacteria with well-defined virulence ...
