Long-term Model for Studying Tumor Microenvironment Complexity: Patient-derived Mini-colons Background: The interaction between tumors and their surrounding microenvironment has profound implications for cancer development and treatment. However, existing in vitro tumor models lack the ability to capture these complex interactions. To address this ...

Using Genome Synteny Analysis for Strain Tracking in Complex Microbiomes Reveals Species-Specific Evolutionary Patterns Background Microbial populations differentiate into distinct strains through single-nucleotide mutations and structural variations such as recombination, insertions, and deletions. Most strain comparison methods primarily quantify...

Single-Sample Tumor Subclonal Reconstruction Algorithm Based on Crowd-Sourced Resources Background The evolution of cancer and the genetic heterogeneity of tumors are critical fields in modern oncology research. Tumors evolve from normal cells through progressive acquisition of somatic mutations. These mutations occur probabilistically, influenced ...

Central Nervous System (CNS) autoimmune diseases, such as Neuromyelitis Optica Spectrum Disorders (NMOSD), are inflammatory demyelinating conditions characterized by relapses of optic neuritis and myelitis. Despite significant progress in the treatment of NMOSD, a subset of patients responds poorly to current therapies, with recurrent and difficult...

Oxidative Phosphorylation Regulates B Cell Effector Cytokines and Promotes Inflammation in Multiple Sclerosis Background Introduction In recent years, the antibody-independent functions of B cells in health and disease have become a research hotspot, particularly their ability to secrete different cytokines that can activate or downregulate local i...

Nucleotide Base Adducts Bind MR1 and Stimulate MR1-Restricted T Cells Abstract This article provides an overview of the latest research by Vacchini et al. on MR1-restricted T cells (MR1T cells), which discovered the presence of nucleotide base adducts as MR1T cell antigens and unveiled their metabolic pathways and physiological functions in tumor c...

TREM2 Deficiency Remodels Intestinal Macrophages and Microbiota to Enhance Anti-PD-1 Tumor Immunotherapy A research team from the Washington University School of Medicine, led by Blanda Di Luccia and other scientists, recently published a study in the journal Science Immunology, revealing how intestinal microbiota and tumor-associated macrophages i...

Immunoglobulin Superfamily Ligand B7H6 Enables T Cell Responses under NK Cell Surveillance Background In the field of immunology, understanding the mechanisms regulating T cell immunity is crucial for developing effective therapies for diseases related to T cell dysfunction, such as autoimmune diseases, chronic infections, and cancer. T cells media...

Major Breakthrough in Research for Autoimmune Neuroinflammation Treatment Background Introduction Steroid resistance is a significant challenge in the treatment of many inflammatory diseases, particularly autoimmune neuroinflammation. In these diseases, TH17 cells (T helper 17 cells) are widely regarded as key contributors to steroid resistance; ho...
