What are the current research efforts aimed at understanding the role of tumor-infiltrating immune cells in cancer immunotherapy? 


Best insight from top research papers

Current research efforts are focused on understanding the role of tumor-infiltrating immune cells (TIICs) in cancer immunotherapy. TIICs, such as tumor-associated myeloid cells (TAMCs) and tumor infiltrating lymphocytes (TILs), have been found to play a significant role in the tumor microenvironment and the efficacy of immune checkpoint blockade . Studies have shown that the origin of TAMCs is not limited to myeloid-biased differentiation in the bone marrow, but also includes abnormal differentiation of splenic hematopoietic stem and progenitor cells, erythroid progenitor cells, B precursor cells, and embryo-derived TAMCs . TILs, on the other hand, reflect the local tumor microenvironment and have been proposed as a superior endpoint in cancer vaccination trials . Various immunotherapy strategies, including immune checkpoint blockade, adoptive cell therapies, chimeric antigen receptor T cells, and monoclonal antibodies, have been developed to target TIICs and improve the clinical outcome of tumor patients . Additionally, the use of imaging methods, such as ultrasonography, magnetic resonance imaging, and positron emission tomography-computed tomography, has been explored to assess the level of TILs in different cancer types .

Which cell receptors should i use for a comprehensive analysis of immune cell infiltration in mouse bone?5 answersFor a comprehensive analysis of immune cell infiltration in mouse bone, utilizing receptor-ligand pairs involved in intercellular interactions is crucial. The immune cell infiltration in bone metastasis involves various immune cell types interacting with tumor and bone cells, influencing metastasis and tumor progression. Notably, the Notch3 receptor plays a significant role in orchestrating leukocyte infiltration and organ fibrosis in kidney injuries, highlighting its importance in immune cell behavior. Additionally, exploring the immune-related role of macrophage scavenger receptor 1 (MSR1) can provide insights into immune cell involvement in gliomas, which can be relevant for bone metastasis studies. By considering these receptors along with other potential immune cell interaction pathways identified in the literature, a more comprehensive understanding of immune cell infiltration in mouse bone can be achieved.
What drives T cell infiltration at tumors?5 answersT cell infiltration into tumors is a crucial factor for the success of T-cell mediated cancer immunotherapies. Several strategies have been explored to enhance T cell trafficking into tumors. One approach is to engineer T cells with synthetic cytokine circuits that locally deliver interleukin-2 (IL-2) to the tumor microenvironment, bypassing tumor suppression mechanisms. Another strategy involves modifying candidate genes in T cells to drive intratumoral T-cell accumulation. A genetic screen identified over 400 candidate genes, including Aak1, which when inhibited, enhanced T-cell trafficking into tumors. Additionally, endogenous nitric oxide (NO) production by T cells has been shown to play a critical role in T cell-mediated tumor immunity. Genetic deletion of Nos2, a gene involved in NO synthesis, in T cells resulted in reduced tumor infiltration and impaired tumor immunity. These findings highlight the importance of cytokine delivery, genetic modifications, and NO production in driving T cell infiltration at tumors.
What are the mechanisms of TLS-mediated intratumoral immune suppression?3 answersTLS-mediated intratumoral immune suppression involves the bypass of DNA lesions by specialized DNA polymerases, including Rev1, which forms a heteroprotein complex. This process allows cancer cells to tolerate DNA adducts formed by chemotherapeutics and promotes chemoresistance. The suppression of TLS has been shown to increase sensitivity of cancer cells to chemotherapy and decrease mutagenesis. The immunosuppressive tumor microenvironment plays a crucial role in limiting the effectiveness of immunotherapy in cancer patients. This microenvironment is orchestrated by stromal myeloid and lymphoid cells, which display inducible suppressive mechanisms triggered by the anti-tumor inflammatory response. These mechanisms include the activation of negative costimulatory signals, impairment of antigen presentation, and the production of immunosuppressive factors. Regulatory cell populations, such as regulatory T cells and immature/mature dendritic cells, also contribute to this immunosuppressive network.
What is markers\ of Tumor infiltrating lymphocytes?4 answersTumor-infiltrating lymphocytes (TILs) are considered to be a manifestation of the host anti-tumor response. The immunophenotype, density, and distribution of TILs have been evaluated in breast cancer samples. TILs can be used as a clinically useful biomarker that has the ability to stratify breast cancer patients in prognostic function. In melanoma, the presence of a dense TIL is associated with good prognosis, and the pattern and activation state of TILs modulate the clinical outcome. Immune infiltrate and programmed death-ligand 1 (PD-L1) expression have been correlated with clinicopathologic characteristics in non-small cell lung cancer (NSCLC). Gene expression assays have been used to measure the intratumoral abundance of immune cell populations, and a list of marker genes has been identified to quantify different immune cell populations, providing insights into the immune infiltrate in tumors.
What is TCR markers of Tumor infiltrating lymphocytes?5 answersT-cell receptor (TCR) markers are used to identify and analyze tumor-infiltrating lymphocytes (TILs) in various types of cancer. TCR gene therapy is a promising treatment approach that involves analyzing the TCR repertoire of TILs. CD8 is a commonly used TCR marker that is associated with cytotoxic T cells. CD8+ T cells have been shown to have prognostic value in multiple tumor types, including colon cancer, breast cancer, and head and neck squamous cell carcinoma (SCCHN). High CD8+ T-cell counts have been associated with better survival and lower risk of metastasis in these cancers. Additionally, the presence of clonally expanded populations of CD8+ T cells within TILs indicates a response to specific antigens in the tumor environment. These findings suggest that CD8 is an important TCR marker for assessing TIL infiltration and predicting patient outcomes in cancer.
