Lipids produced within the thymus give immune cells the initial boost they need to fight off infection
Semi-invariant natural killer T (iNKT) cells wage war against infectious threats, attacking microbial cells and generating signals that enable other immune cells also to respond aggressively. iNKT cells initially ...

Why do neurons die in Parkinson's disease?
Current thinking about Parkinson's disease is that it's a disorder of mitochondria, the energy-producing organelles inside cells, causing neurons in the brain's substantia nigra to die or become impaired. A study from Children's ...

Organelle
In cell biology, an organelle ( /ɔrɡəˈnɛl/) is a specialized subunit within a cell that has a specific function, and is usually separately enclosed within its own lipid bilayer.
The name organelle comes from the idea that these structures are to cells what an organ is to the body (hence the name organelle, the suffix -elle being a diminutive). Organelles are identified by microscopy, and can also be purified by cell fractionation. There are many types of organelles, particularly in eukaryotic cells. Prokaryotes were once thought not to have organelles, but some examples have now been identified.
