Tech Note Measuring Immune Checkpoint Genes from FFPE Tissue Other Applications Tech Note Measuring Immune Checkpoint Genes from FFPE Tissue The immune system’s response to a tumor is modulated by a series of receptor-ligand interactions commonly known as immune checkpoints. Encompassing an intricate balance of stimulatory and inhibitory signals, dysregulation of this system of checks and balances is believed to facilitate tumor immune escape. Due to their critical role in immune response, many of these checkpoints have be targeted for therapeutic intervention, however, due to the large number of potential checkpoints and varying contributions to specific regulatory processes, obtaining a full picture of expression is challenging with existing immunohistochemistry technologies. The HTG EdgeSeq Precision Immuno-Oncology Panel quantitatively measures all described checkpoint Other applications: molecules from a single section of formalin-fixed, paraffin-embedded (FFPE) tissue, providing a fuller view of the immune response to the tumor.

Read Full License Page 1/24 Abstract Colorectal cancer is an overall bad player and accounts for 9% of all cancers. Today, advancements in immune checkpoint inhibition has provided therapeutics for many, but not all cancer patients. This issue is in part due to the tumoral microenvironment; which plays a signicant role in determining response to immune check point therapeutics. This study serves as the rst to evaluate a potent inhibitory checkpoint: V-domain immunoglobulin suppressor of T cell activation (VISTA) and its role in CRC. This was evaluated with both conventional light microscope and superpixel image segmentation. Here we found VISTA expression to be associated with low tumor budding, lower tumor stage, high tumor inltrating lymphocytes, mature stromal differentiation, BRAF mutation status and better disease-free survival in colorectal cancer. When comparing methodologies; superpixel image segmentation better stratied patients into prognostic groups. Anti-VISTA clinical trials are now open and recruiting for patient enrollment for patients with certain advanced solid tumors.

  • VISTA Is a Novel Broad-Spectrum Negative Checkpoint Regulator for Cancer Immunotherapy
    Cancer Immunology Cancer Immunology at the Crossroads: Experimental Immunotherapies Research VISTA Is a Novel Broad-Spectrum Negative Checkpoint Regulator for Cancer Immunotherapy J. Louise Lines1,2, Lorenzo F. Sempere3, Thomas Broughton4,5, Li Wang7, and Randolph Noelle1,2,4,5,6 Abstract In the past few years, the field of cancer immunotherapy has made great progress and is finally starting to change the way cancer is treated. We are now learning that multiple negative checkpoint regulators (NCR) restrict the ability of T-cell responses to effectively attack tumors. Releasing these brakes through antibody blockade, first with anti-CTLA4 and now followed by anti-PD1 and anti-PDL1, has emerged as an exciting strategy for cancer treatment. More recently, a new NCR has surfaced called V-domain immunoglobulin (Ig)-containing suppressor of T-cell activation (VISTA). This NCR is predominantly expressed on hematopoietic cells, and in multiple murine cancer models is found at particularly high levels on myeloid cells that infiltrated the tumors. Preclinical studies with VISTA blockade have shown promising improvement in antitumor T-cell responses, leading to impeded tumor growth and improved survival. Clinical trials support combined anti-PD1 and anti-CTLA4 as safe and effective against late-stage melanoma. In the future, treatment may involve combination therapy to target the multiple cell types and stages at which NCRs, including VISTA, act during adaptive immune responses.

  • Changes in the Adipose Tissue Expression of CD86 Costimulatory
    Sindhu et al., J Glycomics Lipidomics 2015, 5:4 DOI: 10.4172/2153-0637.1000135 Journal of Glycomics & Lipidomics Research Article Open Access Changes in the Adipose Tissue Expression of CD86 Costimulatory Ligand and CD163 Scavenger Receptor in Obesity and Type-2 Diabetes: Implication for Metabolic Disease Sardar Sindhu1*, Reeby Thomas1, Shihab Kochumon1, Eman Alshawaf2, Amal Hasan1, Munera Alghanim1, Kazem Behbehanil2 and Rasheed Ahmad1* 1Immunology & Innovative Cell Therapy Unit, Dasman Diabetes Institute (DDI), Dasman 15462, Kuwait 2Pancreatic Islet Biology and Transplantation Unit, Dasman Diabetes Institute (DDI), Dasman 15462, Kuwait Abstract Background: The CD86 costimulatory ligand and CD163 scavenger receptor are expressed on monocytes/macrophages. However, modulations in the expression of these immune regulatory receptors in metabolic disease remain unclear. We, therefore, compared the adipose tissue expression of CD86/CD163 and signature inflammatory cytokines/chemokines in non-diabetic and diabetic individuals. Methods: Subcutaneous adipose tissue biopsies were collected from 57 non-diabetics and 46 diabetics classified based on body mass index as obese, overweight and lean and the expression of CD86/CD163 was assessed by quantitative RT-PCR, immunohistochemistry/ confocal microscopy. Results: The data show that CD86 and CD163 gene expression was elevated in non-diabetic obese individuals as compared with their lean counterparts (P [CD86] = 0.0035; P [CD163] = 0.0028). As expected, CD86 and CD163 protein expression was also found to be elevated in the adipose tissue samples of obese individuals. The CD86 gene expression in non-diabetic and diabetic individuals correlated positively (P<0.05) with that of TNF-α (r [non-diabetic] = 0.26; r [diabetic] = 0.49), IL-18 (r [non-diabetic] = 0.67; r [diabetic] = 0.63), and IL-8 (r [non-diabetic] = 0.38; r [diabetic] = 0.33).

  • VISTA Regulates the Development of Protective Antitumor Immunity
    Cancer Microenvironment and Immunology Research VISTA Regulates the Development of Protective Antitumor Immunity Isabelle Le Mercier1, Wenna Chen1, Janet L. Lines3,4, Maria Day2, Jiannan Li1, Petra Sergent1, Randolph J. Noelle1,3,4, and Li Wang1 Abstract V-domain Ig suppressor of T-cell activation (VISTA) is a novel negative checkpoint ligand that is homologous to PD-L1 and suppresses T-cell activation. This study demonstrates the multiple mechanisms whereby VISTA relieves negative regulation by hematopoietic cells and enhances protective antitumor immunity. VISTA is highly þ þ expressed on myeloid cells and Foxp3 CD4 regulatory cells, but not on tumor cells within the tumor microenvironment (TME). VISTA monoclonal antibody (mAb) treatment increased the number of tumor- specific T cells in the periphery and enhanced the infiltration, proliferation, and effector function of tumor- reactive T cells within the TME. VISTA blockade altered the suppressive feature of the TME by decreasing the presence of monocytic myeloid-derived suppressor cells and increasing the presence of activated dendritic cells within the tumor microenvironment. In addition, VISTA blockade impaired the suppressive function and reduced þ þ the emergence of tumor-specific Foxp3 CD4 regulatory T cells. Consequently, VISTA mAb administration as a monotherapy significantly suppressed the growth of both transplantable and inducible melanoma. Initial studies explored a combinatorial regimen using VISTA blockade and a peptide-based cancer vaccine with TLR agonists as adjuvants. VISTA blockade synergized with the vaccine to effectively impair the growth of established tumors. Our study therefore establishes a foundation for designing VISTA-targeted approaches either as a monotherapy or in combination with additional immune-targeted strategies for cancer immunotherapy.
