Immunotherapies aimed at strengthening immune effector responses against malignant cells are growing at exponential rates. Alongside, the impressive benefits obtained by patients with advanced melanoma who received adoptively transferred tumor-infiltrating lymphocytes (TILs) have encouraged the scientific community to pursue adoptive cell transfer (ACT)-based immunotherapy. ACT involves autologous or allogenic effector lymphocytes that are generally obtained from the peripheral blood or resected tumors, expanded and activated ex vivo, and administered to lymphodepleted patients...

Tumor infiltrating lymphocytes (TIL) in Epstein-Barr virus (EBV)-associated/microsatellite-unstable (MSI) gastric carcinomas (GC) constitute immune-active principal cellular components of tumor microenvironment and contribute to better prognosis. With the remarkable success of cancer immunotherapies, there is an urgent need for a comprehensive understanding of tumor-immune interactions in patients with GC in the context of host immune response. To identify GC subtype-specific immune response gene set, we tested differentially expressed genes for MSI and EBV+ GC subtypes in randomly selected test set (n = 278) in merged ACRG-SMC microarray and TCGA RNA sequencing data set...

Background - The presence of tumor-infiltrating lymphocytes (TILs) in the tumor microenvironment is associated with an improved prognosis and a better response to therapy in different types of cancer. In this systematic review and meta-analysis, we investigated the prognostic value of T cells in head and neck squamous cell carcinoma (HNSCC). Methods - In a systematic review, Pubmed and Embase were searched for publications that investigated the prognostic value of T cells in HNSCC. A meta-analysis was performed including all studies assessing the association between CD3+, CD4+, CD8+, and FoxP3+ TILs and overall survival (OS), disease-free survival (DFS), or locoregional control (LRC)...

Patients with EGFR mutations showed unfavorable response to programmed cell death-1 (PD-1) blockade immunotherapy in non-small cell lung cancer (NSCLC). Yet the underlying association between EGFR mutation and immune resistance remains largely unclear. We performed an integrated analysis of PD-ligand 1(PD-L1)/CD8 expression and mutation profile based on the repository database and resected early-stage NSCLC in Guangdong Lung Cancer Institute (GLCI). Meanwhile, 2 pool-analyses were set to clarify the correlation between EGFR mutation and PD-L1 expression, and the association of EGFR status with response to anti-PD-1/L1 therapy...

Programmed death ligand 1 (PD-L1) expression is a predictive biomarker of the success of PD-1/PD-L1 inhibitor therapy for patients with advanced non-small cell lung cancer (NSCLC) but its role as a prognostic marker for early stage resectable NSCLC remains unclear. Here, we studied PD-L1 expression and tumor infiltrating lymphocytes (TILs) in surgically resectable NSCLC and correlate the finding with clinicopathological features and patient outcomes. Total of 170 archival samples of resectable NSCLC were probed for PD-L1 expression using the clone 22C3 pharmDx kit...

Recent evidence indicates that tumor infiltrating lymphocytes (TILs), including cytotoxic T cells, are present in the tumor microenvironment of triple-negative breast cancers (TNBC). Despite the presence of cytotoxic T cells, these tumors still develop, progress, and metastasize, suggesting evasion of immune response. One mechanism of immunosuppression is the presence of the T cell inhibitory molecule, programmed death protein 1 (PD-1), on infiltrating T cells and its cognate ligand programmed death ligand 1 (PD-L1) on tumor cells, myeloid dendritic cells (DCs), and macrophages, in the tumor microenvironment...

Triple-negative breast cancer (TNBC) is associated with a poor prognosis, due to its aggressive behaviour and lack of effective targeted therapies. Immunocheckpoint inhibitors, such as anti-programmed cell death 1 (PD-1) and anti-PD-ligand(L)1 agents, are in course of investigation in TNBC, used alone or in combination with other systemic or local approaches. However, the high cost of these drugs and the lack of validated predictive biomarkers support the development of strategies aimed to overcome resistance and optimize the efficacy of these approaches...

γδ T cells usually infiltrate many different types of cancer, but it is unclear whether they inhibit or promote tumor progression. Moreover, properties of tumor-infiltrating γδ T cells and those in the corresponding normal tissue remain largely unknown. Here we have studied features of γδ T cells in colorectal cancer, normal colon tissue and peripheral blood, and correlated their levels with clinicopathologic hallmarks. Flow cytometry and transcriptome analyses showed that the tumor comprised a highly variable rate of TILs (5-90%) and 4% γδ T cells on average, with the majority expressing Vδ1...

Invasive ductal carcinomas of breast with marked stromal lymphocytic infiltration have come to be classified as lymphocyte predominant breast cancer (LPBC) because it obtains high pathological complete response rates with neoadjuvant chemotherapy. Medullary carcinoma (MC), which is independent from LPBC, is a rare histological subtype of invasive breast carcinoma accompanied by abundant lymphoplasmacytic infiltration as LPBC. Although MC shows marked cellular and structural atypia, it usually has a favorable outcome...

Glioblastoma multiforme (GBM) presents the most malignant form of glioma, with a 5-year survival rate below 3% despite standard therapy. Novel immune-based therapies in improving treatment outcomes in GBM are therefore warranted. Several molecularly defined targets have been identified mediating anti-GBM cellular immune responses. Mesothelin is a tumor-associated antigen (TAA) which is expressed in several solid tumors with different histology. Here, we report the immunological significance of mesothelin in human malignant glioma...

Subsets of human tumors are infiltrated with tumor antigen-specific CD8(+) T cells (TILs) despite tumor progression. These TILs are thought to be inactivated by the immunosuppressive tumor microenvironment, through the engagement of inhibitory receptors such as CTLA-4 and PD-1. However, antigen-specific CD8+ TILs are not functionally inert, but are undergoing activation in situ. Here, we show that antigen-specific CD8(+) TIL are actively proliferating, yet also undergo high rates of apoptosis, leading to a vicious cycle of activation and death that limits immune efficacy...

In most eubacteria, the minor AUA isoleucine codon is decoded by tRNAIle2, which has a lysidine (L) in the anticodon loop. The lysidine is introduced by tRNAIle-lysidine synthetase (TilS) through post-transcriptional modification of cytidine to yield an LAU anticodon. Some bacteria, Lactobacillus plantarum for example, possess two tRNAIle2(UAU) genes in addition to, two tRNAIle2(CAU) genes and the tilS gene. tRNA expression from all these genes would generate redundancy in a tRNA that decodes a rare AUA codon...
