Beate Lichtenberger investigates the mechanisms behind cutaneous calcinosis caused by over-activation of Hedgehog signaling in the dermis to improve treatment options.
Cutaneous calcinosis (CUC) is a debilitating condition characterized by the abnormal deposition of calcium salts in the skin and subcutaneous tissues, leading to pain, impaired mobility, and disfigurement. Despite its significant impact on patient quality of life, effective therapeutic interventions for CUC remain lacking, and there is no model system to study the disease. Beate Lichtenberger and her team serendipitously discovered that over-activation of Hedgehog (Hh) signaling in dermal fibroblasts leads to calcium precipitates and inflammation in limb and tail skin of mice, recapitulating the human disease
Beate Lichtenberger will elucidate the underlying mechanisms driving calcium deposition, inflammation, and tissue damage in cutaneous calcinosis. Furthermore, she will perform single cell RNA sequencing (scRNA-Seq) of human CUC tissue to assess which cell types apart from fibroblasts contribute to the pathogenesis and how
By advancing the understanding of the pathogenesis of CUC and developing targeted therapeutic strategies like repurposing of existing Hh inhibitors, Beate Lichtenberger’s project has the potential to revolutionize the treatment landscape and significantly improve the lives of individuals afflicted by this condition.
