Summary:
- The article discusses new research from the National Institutes of Health (NIH) that provides insights into how low-density lipoprotein (LDL), or "bad" cholesterol, works in the body.
- The study found that LDL particles can enter cells and deliver cholesterol even when the LDL receptor, the primary receptor that removes LDL from the bloodstream, is blocked or absent.
- This suggests that there are alternative pathways for LDL to deliver cholesterol to cells, which could have implications for understanding and treating conditions related to high cholesterol levels.
