Claudins are major components of tight junctions and contribute to the epithelial-barrier function by restricting free diffusion of solutes through the paracellular pathway. We have mapped a new...
Systematic Association Mapping Identifies NELL1 as a Novel IBD Disease Gene
Franke, Andre, Hampe, Jochen, Rosenstiel, Philip, Becker, Christian, Wagner, Florian, Häsler, Robert, ...
Crohn disease (CD), a sub-entity of inflammatory bowel disease (IBD), is a complex polygenic disorder. Although recent studies have successfully identified CD-associated genetic variants, these...

We observed two unrelated consanguineous families with malformation syndromes sharing anophthalmia and distinct eyebrows as common signs, but differing for alveolar capillary dysplasia or complex...
Crisponi, Laura, Crisponi, Giangiorgio, Meloni, Alessandra, Toliat, Mohammad Reza, Nürnberg, Gudrun, Usala, Gianluca, ...
Crisponi syndrome is a severe autosomal recessive condition that is phenotypically characterized by abnormal, paroxysmal muscular contractions resembling neonatal tetanus, large face, broad nose,...
Cyclic adenosine monophosphate is a key component of regulatory T cell–mediated suppression
Bopp, Tobias, Becker, Christian, Klein, Matthias, Klein-Heßling, Stefan, Palmetshofer, Alois, Serfling, Edgar, ...
Naturally occurring regulatory T cells (T reg cells) are a thymus-derived subset of T cells, which are crucial for the maintenance of peripheral tolerance by controlling potentially autoreactive T...
Specht, Christoph, Pauels, Hans-Gerd, Becker, Christian, Kölsch, Eckehart
The involvement of counteractive CD8+ T-cell subsets during tumor-specific immune responses was analyzed in a syngeneic murine plasmacytoma model. CD8+ Tc cells against the immunogenic...

A Systematic Approach to Mapping Recessive Disease Genes in Individuals from Outbred Populations
Hildebrandt, Friedhelm, Heeringa, Saskia F., Rüschendorf, Franz, Attanasio, Massimo, Nürnberg, Gudrun, Becker, Christian, ...
The identification of recessive disease-causing genes by homozygosity mapping is often restricted by lack of suitable consanguineous families. To overcome these limitations, we apply homozygosity...
