An Engineered IL-15 Cytokine Mutein Fused to an Anti-PD1 Antibody Improves Intratumoral T Cell Function and Anti-tumor Immunity (human)

Project description:Background: Cancer Immunotherapy with cytokines has demonstrated clinical efficacy but is frequently accompanied with severe adverse events caused by excessive and systemic immune activation. Here, we addressed these challenges by engineering a fusion protein of a single, potency-reduced, IL-15 mutein and an anti-PD1 antibody (αPD1-IL15m). This immunocytokine is designed to deliver PD1-mediated avidity-driven IL-2/15 receptor stimulation preferentially to PD1-positive tumor-infiltrating lymphocytes (TILs) while reducing the natural preference of IL-15 for circulating peripheral NK or T cell Methods: We isolated human lymphocytes from resected hepatocellular carcinoma tissue and cultured these tumor-infiltrating lymphocytes (TILs) in vitro in the presence or absence of an PD1-targeted IL15 mutein, anti-PD1 antibody or IL-15 agonist. After 9 days, CD4+ TILs and CD8+ TILs were sorted by FACS and RNA of 3,000 to 150,000 cells was isolated. Results: The PD1-IL15 fusion cytokine enhanced pro-survival, proliferation and activation pathways in tumor-infiltrating CD4+ and CD8+ cells compared to untreated controls as well as to the combined treatment of single agents (anti-PD1 antibody and IL-15 agonist)

Non-cancerous liver infiltrating lymphocytes of hepatitis C and tumor-infiltrating lymphocytes

Project description:Study goal is to disclose features of gene expressio profile of non-cancerous liver-infiltrating lymphocytes of type C hepatitis patients with hepatocellular carcinomas and tumor-infiltrating lymphocytes of type C hepatitis patients with hepatocellular carcinomas. Keywords: gene expression profile, non-cancerous liver-infiltrating lymphocytes, tumor-infiltrating lymphocytes, type C hepatitis, hepatocellular carcinoma Non-cancerous liver-infiltrating lymphocytes were obtained by laser capture microdissection from surgically resected liver tissues of 12 type C hepatitis patients with hepatocellular carcinoma. The mRNA was amplified and expression profile was comprehensively analyzed with reference RNA using oligo-DNA chip.

Over-expression of GUSB leads to primary resistance of anti-PD1 therapy in hepatocellular carcinoma

Project description:Treatment with immunotherapy, particularly immune checkpoint blockade, can lead to benefit in the clinical setting. However, many preclinical and clinical studies suggest that resistance to anti-PD1 treatment frequently occurs, resulting in tumor relapse and treatment failure in cancer including hepatocellular carcinoma (HCC) patients. In this study ,10 HCC patients were treated with anti-PD1, and the biopsy samples before treatment were used for 289 nanostring panel RNA sequencing to compare responding and non-responding tumors to find possible pretreatment biomarkers or targets of the anti-PD1 therapy response

miRNA expression between CD4+PD1+ and CD4+PD1- T cells

Project description:Recent success in cancer immunotherapy has come from the blockade of inhibitory receptors on T cells, such as programmed cell death-1, which can induce a state of T cell exhaustion upon constant antigen stimulation. Understanding miRNA regulation of PD1 can be useful to discover miRNAs for use in therapy or as prognostic markers in various diseases including cancer, autoimmunity and transplantation. We used microarrays to discover global miRNA expression changes upon PD1 upregulation and identified miRNAs that are both up- and down-regulated. B16F10 cells were injected subcutaneously into C57BL/6 mice and 16 days later CD4+PD1+ and CD4+PD1- were sorted from the lymph nodes and spleen for RNA extraction and hybridization on Affymetrix miRNA array.

PD1 completely suppresses the transcriptional response induced by the T cell receptor

Project description:Functional impairment of the immune response to chronic viral infections and malignancies is characterised by exhausted T cells, which do not respond to antigen. The cell surface receptor PD1 has been implicated in the maintenance of T cell exhaustion and is an attractive target for immunomodulatory approaches to the treatment of such conditions. However, the mechanisms by which PD1 signalling causes exhaustion and the exact response of T cells to PD1 activation are not clear although it has been suggested that PD1 up regulates a number of anti-proliferative factors. Here we perform cytokine and transcriptional profiling of uninfected primary human T cells to characterise these events. We find that PD1 completely prevents cytokine and transcrip- tional changes induced by CD3/28 stimulation. We do not see any factors specifically induced by PD1, including BATF or IL10 which have previously been linked to PD1 activity. Together with the work of others this confirms that PD1 is the sole effector of T cell exhaustion and that infection is responsible for BATF and IL10 up regulation. As a consequence future therapeutic strategies will be confined to the inhibition of PD1 and not a downstream effector.
