Cancer treatment has witnessed transformative advancements over the past few decades, notably with the emergence of CAR-T (Chimeric Antigen Receptor T-cell) therapy. This revolutionary therapy harnesses the body's immune system by genetically engineering T-cells to target and destroy cancer cells. Among the pioneering companies at the forefront of this innovation is Alfa Cytology, renowned for ...
Leukemia, a malignant disorder of the blood and bone marrow, poses significant challenges to both patients and healthcare providers. Traditional treatments, including chemotherapy and radiation, while effective for some, often come with severe side effects and varied success rates. Enter immunotherapy - a groundbreaking approach that is not only redefining leukemia treatment but also offering ...
Gene editing has emerged as a transformative tool in the field of biomedical science, with significant implications for the treatment of various diseases. The primary focus is on harnessing this technology for modifying primary T cells, a type of white blood cell crucial for the immune response. This approach has opened new avenues for immunotherapy, providing hope for treating conditions like ...
Gene delivery is a therapeutic strategy that’s revolutionizing biotechnology and pharmaceuticals. It involves the delivery of new genetic molecules into target cells to treat diseases. This technology has the implicit to revise the treatment of inherited genetic disorders, cancer and other intractable driseases. Scientists are using a variety of gene delivery strategies to insert new ...
As a biology researcher, staying at the cutting edge of technology is crucial to advancing research in the field. The emergence of chimeric antigen receptor T-cell (CAR-T) therapy has revolutionized the treatment of certain cancers, providing a promising targeted approach to eliminate cancer cells. However, the monitoring and detection of CAR-T cells in vivo remain a challenge in the evaluation ...
The T cell antigen receptor (TCR) is a characteristic marker of T cells, playing a crucial role in the immune system. Each T cell typically expresses a specific TCR, which has a unique structure and sequence that can recognize different antigens, including bacteria, viruses, tumor cells, and other pathogens. Once the TCR binds to the antigen, the T cell initiates an immune response, generating ...
In the field of medicine, effectively delivering drugs to the target site in the body is crucial for successful treatment. Over the years, several innovative drug delivery systems have been developed to improve drug efficacy and patient outcomes. In this article, we will discuss four novel drug delivery systems that have shown promising results in recent research. These systems include ...
What is CAR T-cell therapy? Car-t cell therapy involves genetically engineering T cells isolated from patients or allogeneic donors to express chimeric antigen receptors (CAR) that specifically recognize and kill tumor cells. As a "living" drug, CAR-T therapy is very different from traditional drugs. It is a new type of precision targeted therapy for the treatment of tumors. Compared with ...
In the search for innovative and effective ways to target cancer, we are faced with more than just a challenging problem; we are faced with our own cells as opponents. Cancer cells evolve to achieve an optimum of physical fitness, giving them an array of abilities that no cell should possess in a healthy organism. One way to find novel therapies against cancer therefore could imply finding a ...
Mesothelin is a glycosylphosphatidylinositol (GPI)-anchored cell surface glycoprotein. Its biological function has not yet been clarified, but due to its limited distribution in normal tissues and high expression in some tumor tissues, it is expected to be used in tumor-specific treatment. In existing studies of human epidermoid carcinoma cell lines expressing mesothelin, biodistribution analysis ...
Antibody-drug conjugates (ADCs) usually consist of monoclonal antibodies (mAbs) covalently linked to cytotoxic drugs via chemical linkers. With high specific targeting ability and strong killing effect, it has achieved precise and efficient removal of cancer cells, and has become one of the hot spots in the development of anticancer drugs. In 2000, the FDA first approved the ADC drug Mylotarg ...
Cytokines-mediated signaling is a primary way of immune system communication. The common gamma-chain family of cytokines is a set of six cytokines that signal through the common cytokine γ chain receptor (γc/CD132/IL2RG). These cytokines include IL-2, IL-4, IL-7, IL-9, IL-15, and IL-21. Besides the IL-2RG receptor subunit, the γc family cytokine receptors include IL-2RB ...
Chimeric antigen receptor T cells (CAR-T) and T cell antigen receptor chimeric T cells (TCR-T) are currently the "top stream" in adoptive T cell tumor immunotherapy. In particular, CAR-T therapy, which has been approved by the FDA, is rewriting the treatment paradigm of some hematological tumors. However, adoptive T cell therapy remains of little success in solid tumors. The main reason is that ...
Celdara Medical, LLC today announced that the National Cancer Institute of the National Institutes of Health (NIH) has awarded a Small Business Innovation Research (SBIR) Phase I award to fund the company’s proof of concept studies on a new platform to improve chimeric antigen receptor (CAR) T cells efficacy to treat solid tumors. Dr. Joana Murad-Mabaera, who leads this effort, stated, ...
Researchers at Massachusetts General Hospital (MGH) have found that interferon gamma receptor (IFNgR) signaling is essential for the susceptibility of CAR-T cell immunotherapy to kill malignant gliomas. The same phenomenon has been observed in other solid tumors. The findings may partially explain why liquid and solid tumors respond very differently to CAR-T cell therapy. Chimeric antigen ...
At present, chimeric antigen receptor T cell therapy (CAR-T) has made significant achievements in the treatment of specific hematological cancers, allowing patients with relapsed/refractory disease to survive longer and become healthier, but in clinical studies, cell therapy has actually not been successful in the treatment of patients with solid tumors, in part due to the lack of tumor targets ...
Glycosylation is a sophisticated type of post-translational modification that impacts over 50% of cellular proteins and is a critical regulator of many eukaryotic processes. Aberrant glycosylation is a common hallmark of many malignancies and is important at all stages of tumor growth. Glycosylation regulates a range of physiopathological processes, including cell-cell adhesion, cell-matrix ...
Adoptive cell transfer (ACT) therapy is one of the most effective therapeutic options for tumor immunotherapy that is currently emerging in clusters. Chimeric antigen receptors (CARs) and engineered T cell receptors (TCRs) are the main adoptive immunotherapies in recent years. TCR-engineered T cells express tumor antigen-specific receptors with alpha and beta chains generated from high-quality, ...
Immunotherapy, in addition to surgery, chemotherapy, and radiotherapy, has now become the fourth pillar of anticancer treatment, with T cell-based immunotherapy being a successful cancer treatment technique. T cells can be separated into two subpopulations based on the expression of T-cell receptors (TCRs). αβ T cells, expressing expressing αβ TCR, recognize peptide antigens, such as those ...
January 6, 2022—Researchers at the Perelman School of Medicine at the University of Pennsylvania published a research paper in Science titled: CAR-T cells produced in vivo to treat cardiac injury. Heart damage or inflammation can induce fibroblasts to overproduce fibrous material, causing cardiac fibrosis, which hardens the heart muscle and impairs heart function. Heart failure, liver ...
