    Preface

    Cytokines and their receptors have been extensively studied as tumor targets or therapeutic strategies, and have been used for the treatment of cancer patients for more than 40 years



    1

    Cytokines and tumor microenvironment

    Cytokines are secreted by a variety of cell types and are regulators



    Cytokines are key proteins for signaling in the tumor microenvironment (TME) and are multi-potent


    Role of cytokines in the tumor microenvironment (from references)


    2

    Cytokines occur with cancer


    Chronic inflammation is one


    Mechanism of carcinogenic action of interleukins (from references)


    3

    Cytokines and cancer treatment


    Through more than 40 years of research on cytokines, it has been confirmed that it helps anti-tumor immunity, and it has been tried to be used in disease treatment


    Key cytokines in clinical research in cancer therapy (from references)



    With the widespread use of anti-cytokine therapy, especially anticytokine therapy targeting TNF, IL-6 and IL-1, in some inflammatory and autoimmune diseases, preclinical research has provided a basis



    Most clinical trials of the anti-cytokine mAb are early, dose-exploratory safety studies
    conducted in patients with advanced cancer.

    These drug monotherapy have limited or no observed efficacy, but the treatment is generally well tolerated and there are few
    safety issues.

    Therefore, these antagonists are currently being used in combination with other immunotherapy and cancer treatments
    .

    Major cytokines or their receptor antagonists in clinical research in cancer therapy (from the references)

    In summary, cytokines are key elements
    in coordinating TME and controlling tumor-immune cell interactions.

    Although there are still many obstacles to be overcome on the road to clinical development, in-depth study of cytokines in tumor biology can help better understand their mechanism of action and contribute to
    the development of new treatment strategies.

    And the new generation of cytokine therapy for cancer has made a lot of exciting results in preclinical and clinical research, so cytokines can be expected
    in the future of tumor immunotherapy.

    Measured in a cytotoxicity assay using L929 mouse fibrosarcoma cells in the presence of the metabolic inhibitor actinomycin D.
    The ED50 for this effect is typically 3-30 pg/mL.

    High-quality cytokine preparation technology of Yiqiao Shenzhou

    At present, Yiqiao Shenzhou has developed more than 1,100 kinds of cytokine products, covering 240 cytokine targets, including interleukins, interferons, tumor necrosis factors, chemokines, growth factors, lymphocytes, etc
    .

    In order to obtain high-quality cytokine recombinant proteins, Yiqiao Shenzhou has successfully developed a platform for expression including baculovirus-insect cells, mammalian cells and prokaryotic proteins, with the ability to develop more than 1,000 new proteins per year, with production scales ranging from micrograms to kilograms
    .

    Among them, the baculovirus-insect cell expression platform is a eukaryotic expression system that uses baculovirus as a carrier to express exogenous proteins in insect cells, which has the characteristics of high expression efficiency, large capacity of inserted exogenous genes, no threat to operators and the environment, and can modify and process the expressed exogenous proteins after translation, so that the expressed proteins have biological activity
    .

    This system is suitable for the recombinant expression of different types of proteins and can also express multiple proteins
    at the same time.

    So, how do you confirm that the protein is suitable for baculovirus-insect cell expression platforms? How to design the program? In this lecture, Dr.
    Zhang Xuejiao will share the experience of recombinant expression of baculovirus-insect cells based on practical cases, focusing on the construction strategy of baculovirus vectors, the expression of recombinant proteins and the optimization
    of purification protocols.
