Summary
Impaired lymphatic drainage in lymphoedema causes cholesterol buildup, leading to tissue damage. Cholesterol reduction, potentially via agents like cyclodextrin, may treat this chronic condition.
Area of Science:
- Biomedical Science
- Vascular Biology
- Pathophysiology
Background:
- Lymphoedema is a chronic disease from poor lymphatic drainage, causing swelling, inflammation, and fibrosis.
- The precise mechanisms driving lymphoedema progression are not fully understood.
- The role of lymphatic cholesterol transport in lymphoedema pathogenesis is unknown.
Purpose of the Study:
- To investigate the link between impaired lymphatic drainage, cholesterol accumulation, and lymphoedema development.
- To explore cholesterol as a therapeutic target for lymphoedema.
Main Methods:
- Analysis of human lymphoedema tissue to assess cholesterol levels and lymphatic function.
- Development and utilization of mouse models mimicking human lymphoedema.
- Treatment of mouse models with cyclodextrin, a cholesterol-depleting agent.
Main Results:
- Human lymphoedema tissue showed excessive dermal cholesterol accumulation due to impaired lymphatic drainage.
- Cholesterol deposition led to adipose tissue remodeling, adipocyte dysfunction, and fibrosis.
- Cyclodextrin treatment ameliorated swelling and adipose tissue changes in mouse models by restoring lymphatic function and promoting vessel regeneration.
Conclusions:
- Impaired lymphatic cholesterol clearance is a key driver of lymphoedema.
- Tissue cholesterol accumulation contributes to adipose tissue remodeling and fibrosis in lymphoedema.
- Targeting tissue cholesterol represents a potential therapeutic strategy for lymphoedema.

01:29Cholesterol: Significance and Regulation
1.5K
Although not a source of energy, cholesterol plays a significant role as a foundational structure for bile salts, steroid hormones, and vitamin D, as well as being a crucial component of plasma membranes. Approximately 15% of blood cholesterol is derived from our diet, with the remainder synthesized from acetyl CoA by the liver and intestines. Cholesterol is eliminated from the body through its conversion into bile salts, which are eventually discarded in the feces.

138.2K
One example of how cells use the energy contained in electrochemical gradients is demonstrated by glucose transport into cells. The ion vital to this process is sodium (Na+), which is typically present in higher concentrations extracellularly than in the cytosol. Such a concentration difference is due, in part, to the action of an enzyme “pump” embedded in the cellular membrane that actively expels Na+ from a cell. Importantly, as this pump contributes to the high concentration of...

3.5K
The shape of a small drop of liquid can be considered spherical, neglecting the effect of gravity. This drop can further be considered as two equal hemispherical drops put together due to surface tension. The forces acting on the spherical drop are due to the pressure of the liquid inside the drop, the pressure due to air outside the drop, and the force due to the surface tension acting on the two hemispherical drops.

Secondary healthcare is offered by a specialist, generally in hospitals or clinics for patients referred by primary healthcare providers. It occurs when a person has an illness or injury that requires specific medical care. Secondary care is often referred to as acute care. Secondary care can range from uncomplicated care to repair a minor laceration or treat a strep throat infection to more complicated emergent care, such as treating a head injury sustained in an automobile accident.

02:33Phase Transitions: Sublimation and Deposition
20.3K
Some solids can transition directly into the gaseous state, bypassing the liquid state, via a process known as sublimation. At room temperature and standard pressure, a piece of dry ice (solid CO2) sublimes, appearing to gradually disappear without ever forming any liquid. Snow and ice sublimate at temperatures below the melting point of water, a slow process that may be accelerated by winds and the reduced atmospheric pressures at high altitudes. When solid iodine is warmed, the solid sublimes...
