1.MECHANISM OF ACTION

This peptide functions as a defined T-cell epitope. When processed and presented by antigen-presenting cells via MHC class I molecules, it engages with specific T-cell receptors on CD8+ cytotoxic T lymphocytes. This interaction triggers T-cell activation, proliferation, and the release of cytotoxic molecules and cytokines, initiating an adaptive immune response targeted against cells expressing the native tyrosinase antigen, a key process in anti-melanoma immunity and vitiligo pathogenesis.

2.PRODUCT INDICATIONS

The peptide is indicated for research applications in cancer immunology and autoimmunity, including in vitro T-cell activation and proliferation assays, epitope mapping, immune monitoring of melanoma patients, and preclinical evaluation of tyrosinase-targeted immunotherapies such as peptide vaccines and adoptive T-cell transfer. It is also used in studies exploring the mechanisms of immune tolerance and breakdown in autoimmune vitiligo.

3.CLINICAL EFFICACY OF PRODUCT

[Asn370] Tyrosinase(368-376) is a research-grade reagent and is not an approved therapeutic. However, tyrosinase-derived epitopes are central to numerous clinical-stage melanoma vaccine trials. Early-phase clinical studies have demonstrated that immunization with such peptides can induce tyrosinase-specific T-cell responses, and in some cases, correlate with clinical benefit, supporting the continued investigation of this epitope in cancer immunotherapy, though its standalone efficacy requires further validation in larger controlled trials.
