    • Introduction

      CTLA-4 is a member of the immunoglobulin superfamily and encodes a protein which transmits an inhibitory signal to T cells. The protein contains a V domain, a transmembrane domain, and a cytoplasmic tail. Alternate transcriptional splice variants, encoding different isoforms, have been characterized. The membrane-bound isoform functions as a homodimer interconnected by a disulfide bond, while the soluble isoform functions as a monomer. Mutations in this gene have been associated with insulin-dependent diabetes mellitus, Graves disease, Hashimoto thyroiditis, celiac disease, systemic lupus erythematosus, thyroid-associated orbitopathy, and other autoimmune diseases.

    • Introduction

      Cytotoxic T-lymphocyte-associated protein 4 or CTLA4 or CD152 is a receptor that takes part in the immune checkpoint and inhibits immune response. This protein is fundamentally found in regulatory T cells; however, it acts as an enhancer in regular T cells following its activation, this is eminent in cancers. CTLA4 bounds to CD80 or CD86 on the membrane of antigen presenting cells and downregulates transductions.

      Title: Cytotoxic T-Lymphocyte Associated Antigen-4 Human Recombinant: A Potential Immunotherapeutic Target

      Abstract:


      Cytotoxic T-lymphocyte associated antigen-4 (CTLA-4) is a key immune checkpoint receptor that plays a crucial role in regulating T-cell responses. This research paper provides an in-depth analysis of human recombinant CTLA-4, focusing on its production, characterization, and potential applications in immunotherapy. The paper discusses the significance of CTLA-4 in immune regulation, tumor immunity, and autoimmune diseases. Furthermore, it explores ongoing research and clinical trials investigating the therapeutic potential of recombinant CTLA-4 in various pathological conditions. The information presented in this paper aims to enhance our understanding of human recombinant CTLA-4 and its utility as a research tool and a potential immunotherapeutic agent.

      Introduction:


      Cytotoxic T-lymphocyte associated antigen-4 (CTLA-4) is a cell surface receptor primarily expressed on T-cells. It functions as a negative regulator of T-cell activation, dampening immune responses to prevent excessive inflammation. Human recombinant CTLA-4, produced through genetic engineering techniques, provides researchers with a valuable tool to study its biological functions and explore its therapeutic potential.

      Production and Characterization:


      Recombinant CTLA-4 is typically generated using expression systems such as mammalian cells or bacteria. The protein is then purified and characterized to ensure its structural integrity and functional activity. Quality control measures are implemented to confirm the specificity and bioactivity of the recombinant CTLA-4.

      Role in Immune Regulation:


      CTLA-4 plays a critical role in immune regulation by downregulating T-cell activation and suppressing immune responses. It competes with the co-stimulatory receptor CD28 for binding to its ligands, CD80 and CD86, on antigen-presenting cells. This interaction inhibits T-cell activation and promotes immune tolerance. Recombinant CTLA-4 serves as a valuable tool for studying immune checkpoint mechanisms and their impact on immune responses.

      Therapeutic Implications:


      The blockade of CTLA-4 has emerged as a promising immunotherapeutic strategy in cancer treatment. Monoclonal antibodies targeting CTLA-4, such as ipilimumab, have shown significant clinical efficacy in enhancing anti-tumor immune responses. Recombinant CTLA-4-based therapies, including fusion proteins and engineered T-cell receptors, are being explored as potential immunotherapeutic interventions. Additionally, CTLA-4 plays a role in autoimmune diseases, making it a potential target for the development of novel treatments.

      Conclusion:


      Human recombinant CTLA-4 is a valuable research tool and a potential immunotherapeutic target. Its production, characterization, and applications in immune regulation contribute to our understanding of T-cell biology and the development of novel immunotherapies. Continued research and clinical trials investigating the therapeutic potential of recombinant CTLA-4 offer promising prospects for improving outcomes in cancer and autoimmune diseases.

    • Introduction

      CTLA-4 is a member of the immunoglobulin superfamily and encodes a protein which transmits an inhibitory signal to T cells. The protein contains a V domain, a transmembrane domain, and a cytoplasmic tail. Alternate transcriptional splice variants, encoding different isoforms, have been characterized. The membrane-bound isoform functions as a homodimer interconnected by a disulfide bond, while the soluble isoform functions as a monomer. Mutations in this gene have been associated with insulin-dependent diabetes mellitus, Graves disease, Hashimoto thyroiditis, celiac disease, systemic lupus erythematosus, thyroid-associated orbitopathy, and other autoimmune diseases.

    • Synonyms

      GSE, CD152, IDDM12, CELIAC3, CTLA-4.

    • Physical Appearance

      Sterile filtered colorless solution.

    • Immunogen

      Anti-human CTLA4 mAb, clone PAT4F2AT, is derived from hybridization of mouse F0 myeloma cells with spleen cells from BALB/c mice immunized with a recombinant human CTLA4 protein 36-161 amino acids purified from E. coli.

    • Ig Subclass

      Mouse IgG1 heavy chain and Kappa light chain.

    • Clone

      PAT4F2AT.

    • Applications

      The antibody has been tested by ELISA, Western blot analysis to assure specificity and reactivity. Since application varies, however, each investigation should be titrated by the reagent to obtain optimal results. Recommended starting dilution is 1:3000.

    • Type

      Mouse Anti Human Monoclonal.

    • Storage Procedures

      For periods up to 1 month store at 4°C, for longer periods of time, store at -20°C. Prevent freeze thaw cycles.

    • Purification Method

      CTLA4 antibody was purified by protein-A affinity chromatography.
