Function of gene mutations linked to neurological diseases identified

Several gene mutations have been linked to Parkinson's disease, but exactly how and where some of them cause their damage has been unclear. A new Yale study, published in the Journal of Cell Biology, shows that one of the ...

A new puzzle piece to control the aging and age-related diseases

A basic discovery of how the cellular functions are connected to control aging is presented in the journal Cell Metabolism. The study shows that an increasingly deteriorating communication between the cells' organelles is ...

Peroxisomes—the hybrid organelle

Like the human body itself, cells have structures within them that perform special tasks. These cellular structures are called organelles, and discovering more about organelles is key to unlocking the reasons why certain ...

Plant science could aid Alzheimer's research

A finding by an international team of plant biologists could be important in research into Alzheimer's and other age-related diseases.The study is published this week in the prestigious journal Proceedings of the National ...

Researchers reformulate the model of mitochondrial function

The discovery confirms the model proposed by the team in 2008 to account for observations that could not be explained by the established model of mitochondrial function. Mitochondria are the organelles in the interior of ...

When DNA is out of place

When DNA that turns up in the wrong place in mammalian cells, the innate immune system reacts by secreting interferons. The structure and mode of action of the enzyme that mediates this response have now been elucidated.

How disease mutations affect the Parkin protein

Researchers at the MRC Laboratory of Molecular Biology in the United Kingdom have determined the crystal structure of Parkin, a protein found in cells that when mutated can lead to a hereditary form of Parkinson's disease. ...

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.
