Insights Into Gut Barrier Dysfunction and Metabolic Alterations in Mycophenolate‐Induced Enteropathy

Basic &Clinical Pharmacology &Toxicology, Volume 138, Issue 3, March 2026.
ABSTRACT Mycophenolic acid (MPA) is a widely used immunosuppressant whose use is often limited by gastrointestinal toxicity. Gut bacterial hydrolysis of liver‐derived MPA glucuronides increases local exposure to MPA, potentially impairing epithelial barrier function and cellular metabolism.

Timing of NAD Deficiency During Organogenesis Dictates Defect Type and Penetrance

The FASEB Journal, Volume 40, Issue 3, 15 February 2026.
Pregnant mice on a vitamin B3‐free and tryptophan‐limited diet have embryos with Congenital NAD Deficiency Disorder, characterized by malformations and/or death. We longitudinally tracked the maternal NAD metabolome, embryo growth, and malformation occurrence. Mice with lower NAD Salvage Pathway metabolite levels and minimal levels of derived excretion

Impaired Kynurenine Pathway in Inflammatory Bowel Disease

Journal of Clinical Medicine
Background/Objectives: Inflammatory bowel diseases primarily encompass Crohn’s disease and ulcerative colitis. Insufficient levels of tryptophan cause an imbalance in the gut microbiota, leading to inflammation in the gastrointestinal tract. The main catabolic pathway of tryptophan is the kynurenine pathway. Our study aims to evaluate serum tryptophan,

Indoleamine 2,3‐dioxygenase 1 inhibition reverses cancer‐associated fibroblast‐mediated immunosuppression in high‐grade serous ovarian cancer

FEBS Open Bio, Volume 16, Issue 2, Page 432-446, February 2026.
CAF‐mediated immunosuppression in ovarian cancer is driven by IDO1, reducing T‐cell function. Inhibiting IDO1 restores T‐cell proliferation and cytotoxicity, increases cancer cell apoptosis, and may help overcome CAF‐induced immune suppression in high‐grade serous ovarian cancer. Targeting IDO1 may improve antitumor immunity.

Metabolic reprogramming of efferocytosis in the tumour microenvironment: From apoptotic‐cell clearance to therapeutic targeting

Clinical and Translational Medicine, Volume 16, Issue 2, February 2026.
This review systematically deconstructs the pathological efferocytic—metabolic axis in tumours, framing it as a three‐stage, self‐reinforcing cycle: from metabolite‐driven macrophage recruitment, through hijacked surface recognition, to post‐phagocytic metabolic reprogramming that locks in immunosuppression.

Elevating Circulating L‐Kynurenine Promotes Frailty in Aging Mice

Journal of Cachexia, Sarcopenia and Muscle, Volume 17, Issue 1, February 2026.
ABSTRACT Background L‐Kynurenine (L‐Kyn), a product of tryptophan catabolism, increases with age and has been associated with reduced physical function and increased frailty in humans. Robustly expressed in skeletal muscle, kynurenine aminotransferases (KATs) degrade L‐Kyn into kynurenic acid and are regulated by the transcriptional co‐regulator ...

Epstein‐Barr Virus Infection at Single‐Cell Resolution

Journal of Medical Virology, Volume 98, Issue 2, February 2026.
ABSTRACT Epstein‐Barr virus (EBV) infection has been studied at single‐cell resolution for six decades and counting. Such investigations can reveal virus‐host interactions and their dependence on viral strain, cellular niche, infection program, immune response regulation, and time.
