Aselizumab Biosimilar – Anti-SELL, CD62L mAb – Research Grade

Description of Aselizumab Biosimilar - Anti-SELL, CD62L mAb - Research Grade

Introduction to Aselizumab Biosimilar – Anti-SELL, CD62L mAb – Research Grade Aselizumab Biosimilar is a monoclonal antibody (mAb) that targets the SELL protein, also known as CD62L. This protein is found on the surface of leukocytes, specifically on the surface of T cells and B cells. Aselizumab Biosimilar is a biosimilar version of the original Aselizumab, which has been approved for the treatment of multiple sclerosis in Japan. In this article, we will explore the structure, activity, and potential applications of Aselizumab Biosimilar as a therapeutic antibody.

Structure of Aselizumab Biosimilar

Aselizumab Biosimilar is a recombinant, humanized IgG1 monoclonal antibody. It is composed of two heavy chains and two light chains, each containing a variable region and a constant region. The variable region is responsible for binding to the SELL protein, while the constant region determines the effector function of the antibody.

The variable region of Aselizumab Biosimilar is designed to be highly specific for the SELL protein. This is achieved through the use of recombinant DNA technology, where the variable region is derived from a hybridoma cell line that produces the original Aselizumab. The constant region, on the other hand, is derived from human immunoglobulin sequences to minimize potential immunogenicity.

Mechanism of Action of Aselizumab Biosimilar

Aselizumab Biosimilar works by binding to the SELL protein on the surface of leukocytes. This binding prevents the interaction between SELL and its ligand, which is necessary for leukocytes to migrate from the blood into the tissues. As a result, the migration of leukocytes to sites of inflammation is inhibited, reducing the inflammatory response.

In addition, Aselizumab Biosimilar can also induce antibody-dependent cellular cytotoxicity (ADCC) and complement-dependent cytotoxicity (CDC). This means that the antibody can recruit immune cells and complement proteins to target and destroy cells expressing the SELL protein, such as activated leukocytes.

Title: Potential Applications of Aselizumab Biosimilar

Aselizumab Biosimilar has shown promising results in preclinical studies for the treatment of various inflammatory and autoimmune diseases, such as multiple sclerosis, rheumatoid arthritis, and psoriasis. This is due to its ability to inhibit leukocyte migration and reduce inflammation.

In addition, Aselizumab Biosimilar has also been studied for its potential in preventing organ rejection in transplant patients. By inhibiting leukocyte migration, it can prevent the infiltration of immune cells into the transplanted organ, reducing the risk of rejection.

Conclusion

In conclusion, Aselizumab Biosimilar is a recombinant, humanized monoclonal antibody that targets the SELL protein on the surface of leukocytes. Its unique mechanism of action makes it a promising therapeutic option for various inflammatory and autoimmune diseases, as well as for preventing organ rejection in transplant patients. With further research and clinical trials, Aselizumab Biosimilar has the potential to provide effective treatment for these conditions.
