    Applications
    Mesothelin (MSLN) has been identified as a potential therapeutic target due to its unique characteristics. It is not expressed on vital organs, is differentially expressed on certain cancer types with poor prognosis, and is accessible to targeted therapies. However, the precise function and biological role of MSLN in cancer are not fully understood. The existing literature suggests that MSLN's function and prognostic significance may vary depending on the type of tumor. Researchers have developed strategies to enhance the function of MSLN-targeted T cells by incorporating chimeric switch receptors (CSRs) that co-opt the immunosuppressive PD-1/PD-L1 axis and deliver a costimulatory signal. These engineered T cells have shown improved effector function and resistance to exhaustion. Additionally, a novel human antibody VH domain targeting MSLN has been isolated and characterized, demonstrating high affinity and specificity. This antibody has the potential to be used as an antibody-drug conjugate for MSLN-expressing cancers. Further research is needed to fully understand the function and therapeutic implications of MSLN in cancer treatment.

    Published Data

    Fig.1 Reduction in soft agar colony formation and tumor sphere formation is observed when MSLN is knocked down.

    In several stable knockdown clones, MSLN was subjected to Western blot analysis using shMSLN RNA. Representative images were captured, and soft agar colony formation of shC and shMSLN H2052 and H460 cells was quantified.

    Research Highlights

    L, Brendan; Taka, Kazuaki. "Biology of Mesothelin and Clinical Implications: A Review of Existing Literature." World journal of oncology, 2023.
    Since its discovery in 1992, mesothelin (MSLN) has been a topic of interest in the field of therapeutics. It possesses certain qualities that make it a favorable target for therapy. To start with, it is not expressed on any vital organ parenchyma. Additionally, it is differentially expressed on numerous cancer types with poor prognosis and limited systemic treatment options. Its location on the cell membrane allows for targeted therapies with large molecules. While other drug targets have been extensively studied for their therapeutic potential, the exact function and role of MSLN in cancer biology have not been fully elucidated. In this review, the existing literature on the expression patterns and cellular function of MSLN in different tumor types is examined to gain a better understanding of this peculiar molecule. However, the current understanding of MSLN is far from conclusive and there is considerable uncertainty surrounding its precise function and impact on tumor biology. It has also been observed that the expression of MSLN and its relation to prognosis varies among different tumor types. The overall mechanism by which MSLN contributes to tumor aggressiveness remains unclear. Nevertheless, it is evident that there is still much to be uncovered in this area and further research may have significant implications for the treatment of lethal malignancies.

    McCarthy, Derrick. et al. "Functional enhancement of mesothelin-targeted TRuC-T cells by a PD1-CD28 chimeric switch receptor." Cancer immunology, immunotherapy : CII, 2023.
    A novel approach to cancer immunotherapy involves the use of third generation T cells expressing a fusion construct of a mesothelin (MSLN)-specific T cell receptor (TCR) and a CD28 costimulatory domain. These TRuC T cells have demonstrated potent antitumor activity against MSLN-expressing tumors in preclinical models. Additionally, they have been engineered to exhibit increased persistence and decreased potential for immune exhaustion. These promising findings suggest that TRuC T cells have the potential to be a highly effective treatment for cancer patients.
