Autologous haematopoietic stem cell transplantation has been tried as one experimental strategy for the treatment of patients with aggressive multiple sclerosis refractory to other immunotherapies. The procedure is aimed at ablating and repopulating the immune repertoire by sequentially mobilizing and harvesting haematopoietic stem cells, administering an(More)
Macroautophagy (hereafter autophagy) is the major pathway by which macromolecules and organelles are degraded. Autophagy is regulated by the mTOR signaling pathway-the focal point for integration of metabolic information, with mTORC1 playing a central role in balancing biosynthesis and catabolism. Of the various inputs to mTORC1, the amino acid sensing(More)
Huntington’s Disease (HD) is an inherited neurodegenerative disorders caused by CAG repeat expansions in exon 1 of the huntingtin gene (htt). Patients with HD experience profound region specific neural degeneration for reasons that remain incompletely understood. Early studies in HD brain suggest that transcriptional misregulation occurs early in disease,(More)
In addition to its established hematological indications, autologous hematopoietic SCT (HSCT) can ameliorate the course of severe autoimmune disorders through a reconditioning of the immune system. We have shown earlier that HSCT determines extensive renewal of the TCR repertoire in multiple sclerosis patients. However, the observed persistence post-therapy(More)
