Gut microbiota has been widely recognised as playing a critical role in maintaining immune imbalance and the development of rheumatoid arthritis (RA). As key roles mediating interkingdom crosstalk among plants, microbiomes and mammals, plant-derived exosome-like nanoparticles (ELNs) could use lipids and microRNA components to precisely modulate gene expression of gut microbiota, showing potential as a dietary intervention for RA treatment.

Metabolic dysfunction-associated steatohepatitis (MASH) is a multifactorial metabolic liver disease that occurs in the context of obesity, insulin resistance and cardiometabolic comorbidities. Monotherapy targeting single pathways often provides only partial improvements in histological liver fibrosis and systemic metabolic parameters, prompting growing interest in multitargeted combination therapies. Multitargeted and combination strategies for MASH can modulate multiple and complementary pathogenic processes, potentially improving efficacy, promoting liver fibrosis regression, optimising systemic metabolic outcomes and reducing treatment-related adverse effects. Liver-directed combination therapies, such as thyroid hormone receptor-beta (THR-β) agonists along with acetyl-CoA carboxylase (ACC) inhibitors or peroxisome proliferator-activated receptor agonists, aim to improve histological features of MASH. Regimens combining systemic metabolic and liver-specific agents, such as glucagon-like peptide-1 (GLP-1) receptor agonists with fibroblast growth factor-21 analogues or THR-β agonists, aim to optimise metabolic outcomes, including body weight, insulin resistance and plasma lipids. Thoughtfully designed drug pairings, such as diacylglycerol O-acyltransferase 2 inhibitors combined with ACC inhibitors or GLP-1 and glucagon receptor dual agonists, could improve safety and tolerability by leveraging complementary mechanisms that may mitigate adverse effects. These therapeutic strategies aim to achieve more comprehensive and durable improvements in both liver pathology and systemic health than single-agent therapy alone. This review integrates current knowledge on multitargeted and combination therapies for MASH, examines mechanistic rationales and emerging clinical evidence and addresses practical considerations for patient-centred implementation. Therefore, we aim to provide clinicians and researchers with a comprehensive framework to optimise individualised management and improve both hepatic and systemic outcomes in individuals living with MASH.

The efficacy of pharmacological glycogen synthase kinase-3β (GSK3β) inhibition is currently being investigated in unselected cohorts of metastatic pancreatic ductal adenocarcinoma (PDAC). Here, we sought to determine the clinical significance of nuclear GSK3β accumulation in patients with resectable PDAC.

Perianal fistulising disease (PFD) is a complication that affects about 20% of patients with Crohn's disease (CD) whose aetiology remains unknown.

Parasutterella excrementihominis (P. excrementihominis), a Betaproteobacteria species enriched in ulcerative colitis (UC) patients, is implicated in chronic inflammation. However, its mechanistic role in UC progression and colitis-associated colorectal cancer (CAC) remains unclear.

Metabolic dysfunction-associated steatotic liver disease-related hepatocellular carcinoma (MASLD-HCC) is an emerging malignancy with limited therapeutic options. The identity and function of cancer stem cells (CSCs) in MASLD-HCC remain poorly understood. In this study, we characterised CSCs in MASLD-HCC and investigated their contribution to MASLD-HCC tumourigenesis and therapy response.

High ultra-processed food (UPF) intake has been linked to colorectal cancer (CRC), but underlying mechanisms remain unclear.

Colonic diverticulosis is the most common structural abnormality of the colon in developed countries, with an increasing global prevalence. Approximately 20-25% of affected individuals develop symptoms, collectively referred to as diverticular disease. Given its wide clinical spectrum, evolving pathophysiological insights and growing disease burden, updated guidance is essential.

PD-1 blockade has emerged as a promising approach for functional cure of chronic hepatitis B (CHB).

Germline RNF43 mutations cause a dominantly inherited syndrome of colorectal cancer (CRC) and serrated polyps. However, these data originate from highly selected families.

Withdrawal of prolonged nucleos(t)ide analogue (NA) treatment results in hepatitis B surface antigen (HBsAg) loss in some subjects with chronic hepatitis B (CHB), potentially revealing immune correlates of functional cure.

HBV surface antigen (HBsAg) seroconversion indicates the clearance of HBV in patients with chronic HBV infection.

Chronic pancreatitis (CP) is a risk factor for pancreatic cancer, with inherited cases conferring a markedly increased risk. The underlying mechanisms driving malignant transformation by CP remain poorly understood.
