Human keratinocyte caspase-14 expression is altered in human epidermal 3D models by dexamethasone and by natural products used in cosmetics

Caspase-14 is a cysteinyl-aspartate-specific proteinase that is specifically expressed in epidermal keratinocytes. Dysregulation of caspase-14 expression is implicated in impaired skin barrier formation. To elucidate the regulation of caspase-14 in differentiated keratinocytes, we characterized the expression of caspase-14 in normal... Read More

Novel Approach for Characterizing Exposure and Response to Engineered Nanomaterials in the Gut

Despite the expanding number of applications for engineered nanoparticles (ENP), human health concerns associated with ingested nanoparticles are poorly understood. In this study, we utilized a 3D human small intestinal tissue model to develop a physiologically relevant test system that... Read More

Hydrophobic binary mixtures containing amphotericin B as lipophilic solutions for the treatment of cutaneous leishmaniasis

Cutaneous leishmaniasis, caused by Leishmania parasites, requires treatments with fewer side effects than those currently available. The development of a topical solution based on amphotericin B (AmB) was pursued. The considerable interest in deep eutectic solvents (DESs) and their remarkable... Read More
