Planarian flatworms can regenerate their head, including a functional brain, within less than a week. Despite the enormous potential of these animals for medical research and regenerative medicine, the mechanisms of regeneration and the molecules involved remain largely unknown. To identify genes that are differentially expressed during early stages of(More)
Graves' disease is an organ-specific autoimmune disease, and intrathyroidal lymphocytes seem to be the major source of thyroid autoantibodies. Consequently, the intensity of the intrathyroidal lymphocytic infiltration is generally believed to reflect the activity of the autoimmune process. We, therefore, investigated the correlation of microsomal (enzyme(More)
Wnt/β-catenin signaling regulates tissue homeostasis and regeneration in metazoans. In planarians-flatworms with high regenerative potential-Wnt ligands are thought to control tissue polarity by shaping a β-catenin activity gradient along the anterior-posterior axis, yet the downstream mechanisms are poorly understood. We performed an RNA sequencing(More)
Planarians can regenerate their head within days. This process depends on the direction of adult stem cells to wound sites and the orchestration of their progenitors to commit to appropriate lineages and to arrange into patterned tissues. We identified a zinc finger transcription factor, Smed-ZicA, as a downstream target of Smed-FoxD, a Forkhead(More)
Declining thyroid autoantibodies during treatment and decreased lymphocytic infiltration after treatment of patients with Graves' disease suggest immunosuppressive actions of antithyroid drugs. However, the recent report of similar relapse rates after low and high dose carbimazole treatment of Graves' disease seems to contradict the immunosuppression(More)
Several lines of evidence support an etiological role of iodine for the initiation and perpetuation of autoimmune thyroid disease. However, varying relapse rates after increased iodine supplementation have been reported for Graves' disease. Furthermore the effects of iodine on the intensity of human autoimmune thyroiditis have previously only been(More)
Tissue regeneration depends on proliferative cells and on cues that regulate cell division, differentiation, patterning and the restriction of these processes once regeneration is complete. In planarians, flatworms with high regenerative potential, muscle cells express some of these instructive cues. Here, we show that members of the integrin family of(More)
The growth and patterning of anatomical structures from specific cellular fields in developing organisms relies on organizing centers that instruct surrounding cells to modify their behavior, namely migration, proliferation, and differentiation. We discuss here how organizers can form in adult organisms, a process of utmost interest for regenerative(More)
