A cAMP signalosome in primary cilia drives gene expression and kidney cyst formation

The primary cilium constitutes an organelle that orchestrates signal transduction independently from the cell body. Dysregulation of this intricate molecular architecture leads to severe human diseases, commonly referred to as ciliopathies. However, the molecular underpinnings how ciliary signaling orchestrates…

New approach against chronic inflammation

Researchers at the Universities of Bonn and Sao Paulo have succeeded in mitigating chronic inflammation in mice using customized “mini-antibodies.” These nanobodies enabled them to dissolve molecular complexes in tissue that normally activate the immune system. The nanobodies produced may in future…

Immune cells in the brain share the work

This cooperation is impaired in mutations that can cause Parkinson’s disease To break down toxic proteins more quickly, immune cells in the brain can join together to form networks when needed. This is shown by a joint study of the University of Bonn, the German Center for Neurodegenerative Diseases (DZNE) and the Institut François Jacob…

Guidelines for the use of flow cytometry and cell sorting in immunological studies (second edition)

Guidelines for the use of flow cytometry and cell sorting in immunological studies (second edition)

The European Journal of Immunology has published the second edition of the very comprehensive guide to flow cytometry  and cell sorting in immunological studies. And we contributed to that edition. Here is the information from the abstract: “These guidelines are a consensus work of a considerable number of members of the immunology and flow cytometry…

A comprehensive overview of all new devices of the Flow Cytometry Core Facility

A comprehensive overview of all new devices of the Flow Cytometry Core Facility

In 2018 the Flow Cytometry Core Facility was able to acquire five new instruments. A FACSAria Fusion cell sorter, a second LSRFortessa cell analyzer and an ImageStream  image cytometer were granted by the DFG through a large device application. (“Forschungsgroßgeräte” nach Art.91b GG) Special thanks goes to the excellence cluster “ImmunoSensation”and to the SFB TR57 .  A…

A Genome-wide CRISPR Screen Identifies NEK7 as an Essential Component of NLRP3 Inflammasome Activation

A Genome-wide CRISPR Screen Identifies NEK7 as an Essential Component of NLRP3 Inflammasome Activation

The Journal of Biological Chemistry, 291, 103-109. The mechanisms of NLRP3 activation are still poorly understood. Jonathan Schmid-Burgk and colleagues present new data on the identification of NEK7, which specifically functions upstream of NLRP3 activation. NEK7 was identified in an unbiased genetic screening approach, which employed the CRISPR technology to identify macrophages that were rendered…

50th Anniversary

50th Anniversary

This would be the perfect time to ask something like ” how old is this flow cytometry stuff”. This month sees the 50 years anniversary of the first publication on cell sorting by Mack Fulwyler (Science 1965) and a first description of a Spectrophotometer for ultrarapid cell analysis by Louis Kamentsky and Myron Melamed (Science…
