Nerve- and Airway-Associated Interstitial Macrophages Mitigate SARS-CoV-2 Pathogenesis via Type I Interferon Signaling

1. Academic Background The COVID-19 pandemic has highlighted the importance of immunoregulatory mechanisms in respiratory viral infections. Despite vaccine advancements, the rapid mutation of SARS-CoV-2 continues to threaten public health. Studies indicate that severe COVID-19 cases are often associated with dysregulated immune responses rather tha...

Intestinal Epithelium–Derived IL-34 Reprograms Macrophages to Mitigate Gastrointestinal Tract Graft-Versus-Host Disease

Academic Report on the Role of Intestinal Epithelium-Derived IL-34 in Alleviating Graft-versus-Host Disease 1. Academic Background Graft-versus-Host Disease (GVHD) is a severe complication following allogeneic hematopoietic stem cell transplantation (allo-HSCT), and gastrointestinal (GI) GVHD is the primary determinant of morbidity and mortality du...

Myeloid Beta-Arrestin 2 Depletion Alleviates Metabolic Dysfunction-Associated Steatohepatitis through Metabolic Reprogramming of Macrophages

The Loss of β-arrestin 2 in Hepatic Macrophages Alleviates Metabolic Dysfunction-associated Steatohepatitis — Through Metabolic Reprogramming of Macrophages Background and Motivation Metabolic dysfunction-associated fatty liver disease (MASLD) is a globally prevalent health issue, affecting approximately 25% of the population. This disease includes...

Nicotinamide Metabolism Face-off Between Macrophages and Fibroblasts Manipulates the Microenvironment in Gastric Cancer

Macroscopic and Microscopic Mechanisms of Nicotinamide Metabolism Antagonism: Manipulation of the Gastric Cancer Microenvironment Background Introduction Gastric cancer (GC) is a type of cancer characterized by a unique and heterogeneous tumor microenvironment (TME). Despite advances in immune checkpoint blockade (ICB) therapy for gastric cancer, n...

Role of Macrophages in CL-Enhanced Regeneration After Peripheral Nerve Injury

Key Research on the Role of Macrophages in Peripheral Nerve Regeneration Background and Research Objectives Since the 1990s, research has shown that macrophages play a promoting role in peripheral nerve regeneration, and are particularly important in the conditioning lesion (CL) response. After sciatic nerve injury, macrophages accumulate at the in...
