Tyrosinase Driven‐Intracellular Polymerization of a Porphyrin Derivative Induced Immunogenic Death of Melanoma Cells and Strengthened Photodynamic Therapy

Advanced Science, EarlyView.
This study uses tyrosinase, which is highly expressed in melanoma, to drive porphyrins to polymerize and self‐assemble within tumor cells to form retented microstructures. This process induces immunogenic death and activates immune responses (M1 macrophages, dendritic cells, CD8+T cells), turning “cold” tumors into “hot” tumors.

Antamanide Analogs as Potential Inhibitors of Tyrosinase

International Journal of Molecular Sciences, 2022
The tyrosinase enzyme, which catalyzes the hydroxylation of monophenols and the oxidation of o-diphenols, is typically involved in the synthesis of the dark product melanin starting from the amino acid tyrosine. Contributing to the browning of plant and fruit tissues and to the hyperpigmentation of the skin, leading to melasma or age spots, the ...
