Atherosclerosis (AS) is a chronic inflammatory vascular disease closely tied to cellular metabolism. Recent genome-wide association study data have suggested the significant roles of endothelial cells, smooth muscle cells, and macrophages in the regression and exacerbation of AS. However, the impact of cellular crosstalk and cellular metabolic derangements on disease progression in AS is vaguely understood. In this review, we analyze the roles of the three cell types in AS. We also summarize the crosstalk between the two of them, and the associated molecules and consequences involved. In addition, we emphasize potential therapeutic targets and highlight the importance of the three-cell co-culture model and extracellular vesicles in AS-related research, providing ideas for future studies.

The global incidence of biliary tract cancer (BTC) is on the rise, presenting a substantial healthcare challenge. The integration of immune checkpoint inhibitors (ICIs) with molecularly targeted therapies is emerging as a strategy to enhance immune responses. However, the efficacy and underlying mechanisms of these treatments in BTC are still largely unexplored.

Objectives: Blocking interleukin (IL)-6-receptor with tocilizumab has been a major advance in the treatment of giant-cell arteritis (GCA), supporting a crucial role of IL-6 receptor signalling. However, nearly half of the patients are not able to maintain glucocorticoid- free remission with tocilizumab. The impact of tocilizumab on vascular lesions of GCA is largely unknown since conflicting results have been obtained by imaging.

During angiogenesis, sprouting endothelial cells (ECs) migrate and eventually connect to target vessels to form new vessel branches. However, it remains unclear how these sprouting vessels migrate toward the target vessels in three-dimensional space. We performed in vivo imaging of the cerebral capillary network formation in zebrafish to investigate how sprouting tip cells migrate toward their targets.

L-asparaginase is a critical therapeutic enzyme for treating acute lymphoblastic leukemia (ALL), a common childhood malignancy. In this study, the L-asparaginase coding sequence from halophilic Vibrio sp. (GBPx3) was cloned, expressed in Escherichia coli, and characterized.

Mammalian cells synthesize hundreds of different variants of their prominent membrane lipid phosphatidylcholine (PC), all differing in the side chain composition. This batch is constantly remodeled by the Lands cycle, a metabolic pathway replacing one chain at the time. Using the alkyne lipid lyso-phosphatidylpropargylcholine (LpPC), a precursor and intermediate in PC synthesis and remodeling, we study both processes in brain endothelial bEND3 cells.
