Immune cells in the pathogenesis of abdominal aortic aneurysm: Roles, regulation and targeted interventions

Clinical and Translational Discovery, Volume 6, Issue 5, October 2026.
This review provides a comprehensive overview of how macrophages, neutrophils, T cells and other immune cells infiltrate the aortic wall, undergo phenotypic shifts and interact with one another in abdominal aortic aneurysm (AAA). Background Abdominal aortic aneurysm (AAA) is a lethal degenerative vascular disease with no approved clinical drugs. Immune

Inhibition of indoleamine 2,3 dioxygenase activity by H2O2

, 2006
Indoleamine 2,3-dioxygenase is the first and rate limiting enzyme of the kynurenine pathway of tryptophan metabolism, has potent effects on cell proliferation and mediates antimicrobial, antitumorogenic, and immuno suppressive effects.

Kynurenine acts as a signaling molecule to attenuate pulmonary fibrosis by enhancing the AHR-PTEN axis

Journal of Advanced Research
Introduction: Pulmonary fibrosis (PF) is a fatal fibrotic lung disease without any options to halt disease progression. Feasible evidence suggests that aberrant metabolism of amino acids may play a role in the pathoetiology of PF.

Microbiome‐Derived Tryptophan Metabolites Regulate AhR Signaling to Restore Epithelial Barrier Integrity in Inflammatory Bowel Disease

MicrobiologyOpen, Volume 15, Issue 5, October 2026.
The graphical abstract illustrates how microbiome‐derived indoles activate the aryl hydrocarbon receptor to restore the intestinal barrier. The picture contrasts the “leaky gut” state with the restored homeostasis achieved through AMPK, Nrf2, and IL‐22 signaling.

Harnessing Natural Killer Cells: From Neuroimmunology to Novel Therapies for Central Nervous System Diseases

MedComm, Volume 7, Issue 10, October 2026.
This review delineates the multifaceted roles of natural killer (NK) cells in the central nervous system, spanning direct cytolysis, immunoregulation, and crosstalk with the brain microenvironment. We evaluate the translational potential and challenges of NK cell immunotherapies for a spectrum of neurological conditions.

H2S induces apoptosis of tumors with high IDO1 expression via NR4A1-BCL-2 and SOCS3 pathways

Cellular & Molecular Biology Letters
Background Hydrogen sulfide (H2S) has been reported to exert both protumor and antitumor functions. It is worthy to clarify the condition under which H2S exerts antitumor effects and its underlying mechanism.

The role of indoleamine 2,3 dioxygenase 1 in the osteoarthritis.

American journal of translational research
Osteoarthritis (OA) is a chronic degenerative joint disease and a leading cause of disability. It involves articular cartilage destruction and a whole joint inflammation. In spite of OA pathogenesis is still unclear, new studies on the OA pathophysiological aetiology and immunomodulation therapy continuously achieve significant advances with new ...

Ineffectiveness of immune checkpoint inhibitors in prostate cancer: is it just a question of ‘‐mabs’?

The Journal of Pathology, Volume 270, Issue 2, Page 139-162, October 2026.
Abstract Prostate cancer (PCa) is the second most common type of neoplasm, currently treated with a variety of therapeutic agents. Although advances in treatment over the past decade have improved overall survival, patients with advanced PCa eventually progress from hormone‐sensitive PCa to metastatic castration‐resistant PCa.

Nonpathogenic SIV Infection in Sooty Mangabeys Is Characterized by a Lack of Activation and Expansion of Monocytes

Journal of Medical Primatology, Volume 55, Issue 5, October 2026.
ABSTRACT Introduction Natural hosts of simian immunodeficiency virus (SIV), including sooty mangabeys (SMs), maintain high viremia without progressing to AIDS and AIDS‐associated histopathogenesis. The mechanisms underlying this protection and lack of pathogenesis remain incompletely understood, particularly in relation to monocyte/macrophage ...
