Image for: FMP and MDC Researchers Identify a Fundamental Process in Lysosomal Function and Protein Degradation


CT scan of the tibia. Healthy bone (left) is characterized by a lattice of trabecular bone and a clear marrow cavity. The bones of mice, in which the chloride/hydrogen ion exchanger CIC-7 has been converted into a pure chloride conductor (middle) show an irregular cluster of bone tissue, a mild form of osteopetrosis. If the protein CIC-7 is totally lacking (right) the function of the bone degrading cells is completely disrupted, leading to a severe form of osteopetrosis, also known as marble bone disease.

Combination of search terms

You can combine search terms with and, or and/or not, e.g. Philo not logy.

Brackets

You can use brackets to separate combinations from each other, e.g. (Philo not logy) or (Psycho and logy).

Phrases

Coherent groups of words will be located as complete phrases if you put them into quotation marks, e.g. “Federal Republic of Germany”.

Selection criteria

You can also use the advanced search without entering search terms. It will then follow the criteria you have selected (e.g. country or subject area).

If you have not selected any criteria in a given category, the entire category will be searched (e.g. all subject areas or all countries).
