Anti-MAGEA4 CAR-T Preclinical in vivo Assay

Target Background

MAGEA4 (melanoma-associated antigen 4) is very similar to MAGEA3. It is expressed only in immune privileged reproductive tissues (primary spermatocytes, spermatogonia in male and placental trophoblast in female). As a tumor-specific protein, MAGEA4 also expresses exclusively and aberrantly on multiple tumors (melanoma, non-small cell lung cancer, hematologic malignancies, etc.) excluding most normal somatic cells, and plays an active role in driving cancer progression and indicates bad prognosis. Therefore, MAGEA4 is an attractive immunotherapeutic target for the anti-MAGEA4 CAR-T cell therapy.

Anti-MAGEA4 CAR-T Cell Therapy

Since MAGEA4 plays a critical role in multiple human malignancies, several phase 1 clinical trials (NCT02239861, NCT02291848, NCT01333046) try to apply tumor-associated antigen (TAA)-specific cytotoxic T lymphocytes for the treatment of multiple human malignancies. Creative Biolabs is dedicated to assisting researchers to initiate and develop the cutting-edge anti-MAGEA4 CAR-T cell therapy.

Animal Models for in vivo Study of anti-MAGEA4 CAR-T Cell Therapy

Creative Biolabs offers researchers almost all the animal models generated from the major techniques including the conventional carcinogen-induced models, the mosaic transposon- or virus-induced models, the transgenic models and the subcutaneous or patient-derived xenograft models for a variety of human malignancies. In addition, Creative Biolabs also assists customers in creating clinically relevant animal models including but not limited to the above categories. You request, Creative Biolabs offers the best.
