Restriction enzyme analysis was done on total cellular DNA extracted from whole blood in two patients with mitochondrial myopathy and multisystem involvement and their families. The two patients had an abnormal mitochondrial genome with a large (about 8 kb) duplication present in several tissues. Normal mitochondrial DNA (mtDNA) was also present, but within(More)
Intrathymic T-cell development is critically dependent on cortical and medullary thymic epithelial cells (TECs). Both epithelial subsets originate during early thymus organogenesis from progenitor cells that express the thymoproteasome subunit β5t, a typical feature of cortical TECs. Using in vivo lineage fate mapping, we demonstrate in mice that β5t(+) TEC(More)
Two patients with direct tandem duplications of mitochondrial DNA (mtDNA) and mitochondrial myopathy are described. The breakpoint regions between duplicated segments were amplified using the polymerase chain reaction (PCR), cloned and sequenced. The distribution of normal and abnormal genomes in different tissues was investigated using Southern(More)
Neisseria meningitidis is a major global pathogen causing invasive disease with a mortality of 5-10%. Most disease in developed countries is caused by serogroup B infection, against which there is no universal vaccine. Opacity-associated adhesin (Opa) proteins are major meningococcal outer membrane proteins, which have shown recent promise as a potential(More)
