The liver's role in metabolism, detoxification, and immune regulation underscores the urgency of addressing liver diseases, which claim millions of lives annually. Due to donor shortages in liver transplantation, liver tissue engineering (LTE) offers a promising alternative. Hydrogels, with their biocompatibility and ability to mimic the liver's extracellular matrix (ECM), support cell survival and function in LTE. This review analyzes recent advances in hydrogel-based strategies for LTE, including decellularized liver tissue hydrogels, natural polymer-based hydrogels, and synthetic polymer-based hydrogels. These materials are ideal for in vitro cell culture and obtaining functional hepatocytes. Hydrogels' tunable properties facilitate creating artificial liver models, such as organoids, 3D bioprinting, and liver-on-a-chip technologies. These developments demonstrate hydrogels' versatility in advancing LTE's applications, including hepatotoxicity testing, liver tissue regeneration, and treating acute liver failure. This review highlights the transformative potential of hydrogels in LTE and their implications for future research and clinical practice.

Background: () is a widely prevalent intracellular parasite that infects almost all warm-blooded animals and causes serious public health problems. The drugs currently used to treat toxoplasmosis have the disadvantage of being toxic and prone to the development of resistance, and the only licensed vaccine entails a risk of virulence restoration. The development of a safe and effective vaccine against is urgently needed.

Macrophages play crucial roles in immune response and tissue homeostasis, with their functions becoming increasingly complex in obesity-mediated metabolic disorders. This review explores the extensive range of macrophage activities within adipose and liver tissues, emphasizing their contribution to the pathogenesis and progression of obesity and its related metabolic dysfunction-associated steatotic liver disease (MASLD). In the context of obesity, macrophages respond adaptively to lipid overloads and inflammatory cues in adipose tissue, profoundly influencing insulin resistance and metabolic homeostasis.

Background And Aims: The diagnostic value of primary biliary cholangitis (PBC)-specific antibodies in patients with elevated alkaline phosphatase (ALP) and gamma-glutamyl transferase (GGT) levels, and other identifiable causes, was unclear. Our study aimed to determine whether etiological treatments in PBC-specific antibody-positive patients could improve liver biochemical tests, thereby distinguishing them from individuals with PBC.
Methods: We enrolled patients who were positive for PBC-specific antibodies and elevated ALP and/or GGT levels but with other identifiable etiologies.

Background And Aims: Notch1 protein plays a significant role in hepatic metabolism, as evidenced by its correlation with insulin resistance in the livers of obese individuals, making it an intriguing research target. Therefore, this study aims to investigate the impact of aerobic exercise on Notch1 pathways in the hepatic tissue of obese mice and its role in controlling hepatic metabolism.
Methods: Therefore, we conducted a cross-sectional study utilising liver biopsies from lean and obese humans, as well as an intervention study involving mice subjected to a high-fat diet.
