Protective role of Pannexin1 in lymphatic endothelial cells in the progression of atherosclerosis in female mice.

Atherosclerosis is a progressive arterial disease arising from imbalanced lipid metabolism and a maladaptive immune response. The lymphatic system ensures tissue fluid homeostasis, absorption of dietary fats and trafficking of immune cells to draining lymph nodes, thereby potentially affecting atherogenesis. Endothelial cell-specific deletion of Pannexin1 (Panx1) in apolipoprotein E-deficient (Apoe-/-) mice increased atherosclerosis, suggesting a protective role for Panx1 channels in arterial endothelial function.

Unravelling molecular mechanisms in atherosclerosis using cellular models and omics technologies.

Despite the discovery and prevalent clinical use of potent lipid-lowering therapies, including statins and PCSK9 inhibitors, cardiovascular diseases (CVD) caused by atherosclerosis remain a large unmet clinical need, accounting for frequent deaths worldwide. The pathogenesis of atherosclerosis is a complex process underlying the presence of modifiable and non-modifiable risk factors affecting several cell types including endothelial cells (ECs), monocytes/macrophages, smooth muscle cells (SMCs) and T cells. Heterogeneous composition of the plaque and its morphology could lead to rupture or erosion causing thrombosis, even a sudden death.

Channel-assembling tumor microenvironment on-chip for evaluating anticancer drug efficacy.

Organ-on-a-chip is an advanced system for evaluating drug response in diseases. It simulates the in vivo tumor microenvironment, aiding in the understanding of drug mechanisms and tumor responses. It mimics the structure of the tumor microenvironment and the dynamic conditions within the body.

Anisotropic tumor spheroid remission with binary tumor-microenvironment-on-a-chip.

Microphysiological system (MPS) is a powerful tool for the in vitro disease validation platform. It is employed to substantially enhance understanding of tumor and their microenvironments. It aims to assist or replace preclinical studies for validating the efficacy of anti-cancer drugs, precision medicine, and investigating metastatic mechanisms.
