Introduction: Obesity has been linked to vascular dysfunction, cognitive impairment and neurodegenerative diseases. However, experimental models that recapitulate brain pathology in relation to obesity and vascular dysfunction are still lacking.

Methods: In this study we performed the histological and histochemical characterization of brains from Ldlr-/-.

Background: Non-alcoholic steatohepatitis (NASH) has become one of the most common liver diseases and is still without approved pharmacotherapy. Lifestyle interventions using exercise and diet change remain the current treatment of choice and even a small weight loss (5-7%) can already have a beneficial effect on NASH. However, the underlying molecular mechanisms of exercise and diet interventions remain largely elusive, and it is unclear whether they exert their health effects via similar or different pathways.

Non-alcoholic steatohepatitis (NASH) is a fast-growing liver disorder that is associated with an increased incidence of cardiovascular disease and type 2 diabetes. Animal models adequately mimicking this condition are scarce. We herein investigate whether Ldlr-/-.

The cellular composition of atherosclerotic lesions is determined by many factors including cell infiltration, proliferation and cell death. Tumor suppressor gene p53 has been shown to regulate both cell proliferation and cell death in many cell types. In the present study, we investigated the role of macrophage p53 in the pathogenesis of early and advanced atherosclerosis.

The cellular composition of an atherosclerotic lesion is determined by cell infiltration, proliferation, and apoptosis. The tumor suppressor gene retinoblastoma (Rb) has been shown to regulate both cell proliferation and cell death in many cell types. To study the role of macrophage Rb in the development of atherosclerosis, we used apoE-deficient mice with a macrophage-restricted deletion of Rb (Rb(del) mice) and control littermates (Rb(fl) mice).

Article Synopsis
  • The study presents a method to selectively alter genes in specific blood vessel regions using a specialized drug delivery device.
  • A 4-hydroxytamoxifen (4-OHT)-releasing device was tested on mice with a specific genetic setup to target smooth muscle cells (SMCs) in arteries.
  • The results showed that optimal gene modification occurred with a 1% concentration of 4-OHT applied locally for 7 days, significantly enhancing targeted gene changes while sparing surrounding cells.

Objective: Tumor necrosis factor-alpha (TNFalpha) is a pleiotropic cytokine exerting both inflammatory and cell death modulatory activity, and is thought to play a role in the pathogenesis of atherosclerosis. Studies in mice indicated that TNFalpha affects atherosclerosis minimally or not under conditions that allow fatty streak formation. Here, we examined the possible role of TNFalpha in advanced and complex atherosclerotic lesions.
