About LRRC15
Leucine-rich repeat-containing protein 15 (LRRC15) is a type I transmembrane protein involved in cell-cell and cell-extracellular matrix (ECM) interactions. It is overexpressed in various mesenchymal tumors such as sarcoma, glioblastoma and melanoma, where it promotes tumor metastasis. Additionally, LRRC15 is upregulated in cancer-associated fibroblasts (CAFs) across various cancer types, contributing to immune-excluded and immune-suppressive tumor microenvironment (TME). This makes LRRC15 an appealing target for cancer therapy.
