CS1 or SLAMF7, CD319 is a cell-surface glycoprotein, which is manifested as a robust marker in CD138-purified primary tumor cells from the majority of multiple myeloma (MM) patients, while exists at low levels on normal NK cells, some T-cell subsets, plasma cells (PCs) and almost undetectable on myeloid cells and the majority of other healthy tissues, especially hematopoietic stem cells. Pathological augment of CS1 may cooperate with CD138 to promote MM cell adhesion, clonogenic growth, and tumorigenicity via c-Maf-mediated interaction with bone marrow stromal cells. Since CS1 is highly and nearly ubiquitously expressed on MM cells other than normal cells especially the hematopoietic stem cells, CS1-targeted cytotoxic leukocytes will not impair major immune cell subsets, which makes anti-CS1 CAR-T a promising immunotherapy.

Anti-CS1 CAR-T Cell Therapy
As a humanized anti-CS1 monoclonal IgG1 antibody, Elotuzumab (HuLuc63) is found to inhibit myeloma cell adhesion to the bone marrow stromal cell, subsequently, induce NK cell-mediated antibody-dependent cellular cytotoxicity and promote NK cell activation without killing autologous NK cells. The efficiency study of anti-MM in preclinical models and several phase 1/2 clinical trials (NCT00742560, NCT00726869, and NCT00425347) has manifested the therapeutic potential of targeting CS1 for the treatment of MM. Therefore, anti-CS1 CAR-T cell immunotherapy will be a promising mean to augment the anti-MM capacity in the near future. Creative Biolabs is dedicated to assisting researchers to initiate and develop the cutting-edge anti-CS1 CAR-T cell therapy.
Animal Models for in vivo Study of anti-CS1 CAR-T Cell Therapy
As an almost incurable plasma-cell malignancy, MM is characterized by osteolytic bone disease and immunosuppression. Creative Biolabs provides multiple murine models of MM for the better understanding of the elusive pathogenesis and the unceasing development of novel therapeutic strategies. The MM animal models of Creative Biolabs are generated from the major techniques including the conventional carcinogen-induction (such as pristine oil), the mosaic transposon- or virus-induction, the transgenesis and the subcutaneous or patient-derived xenograft (such as 5T2MM, 5T33). 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.
