背景信息

LRRC15 (leucine-rich repeat-containing protein 15) is a transmembrane or secreted protein belonging to the leucine-rich repeat (LRR) superfamily, characterized by repeating units of 20-30 amino acids rich in leucine. These repeats mediate protein-protein interactions, enabling LRRC15 to function as a scaffold or signaling modulator. First identified in 2003. LRRC15 is expressed in developing tissues like bone, skin, and muscle, but shows limited distribution in healthy adults. However, its expression is significantly upregulated in pathological conditions, particularly in cancer-associated fibroblasts (CAFs), fibrotic tissues, and inflamed microenvironments.

Recent studies highlight LRRC15 as a dynamic player in tissue remodeling and disease. In cancers (e.g., pancreatic, breast, glioblastoma), LRRC15 overexpression correlates with poor prognosis, potentially promoting tumor progression by modulating TGF-β signaling and extracellular matrix (ECM) stiffness. Its unique expression pattern has made it an emerging biomarker for targeted therapies; antibody-drug conjugates targeting LRRC15 are currently in clinical trials. Intriguingly, LRRC15 also serves as a receptor for SARS-CoV-2 spike protein in certain cell types, revealing an unexpected role in viral entry.

Recombinant LRRC15 proteins, typically produced in mammalian or insect expression systems, enable functional studies of its ectodomain interactions. These tools help decipher its binding partners (e.g., integrins, growth factors) and therapeutic potential. Challenges remain in fully characterizing its dual roles in tissue repair versus pathological fibrosis and its context-dependent signaling. Nevertheless, LRRC15 represents a promising target for precision medicine, bridging regenerative biology and disease intervention.
