Antigen presentation of the Oct4 and Sox2 peptides by CD154-activated B lymphocytes enhances the killing effect of cytotoxic T lymphocytes on tumor stem-like cells derived from cisplatin-resistant lung cancer cells

The present study investigated whether antigen presentation of the Oct4 and Sox2 peptides by CD154-activated B lymphocytes can enhance the killing effect of CD8+ cytotoxic T lymphocytes (CTLs) on lung stem-like cancer cells (SLCCs). The CTLs were generated using an accelerated co-cultured dendritic cells (DC) (acDC) assay by incubating human peripheral blood mononuclear cells (PBMCs) from non-small-cell lung cancer patients with antigen peptides of Oct4 and Sox2 in the presence of several DC-activating agents. CD154+ NIH3T3 cells prepared by CD154 lentiviral transfection were used as feeder layer to activate primary B cells (CD19+) obtained from PBMCs. Activated B cells were co-cultured with CTLs to present antigen peptides of Oct4 and Sox2. CTLs co-cultured with activated B cells were evaluated for the levels of secreted inflammatory cytokines using ELISA. In addition, the killing effect of the CTLs on SLCCs derived from cisplatin-resistant strain of human lung cancer cell line PC9 was evaluated by flow cytometry using CFSE labeling of the target cells. After the acDC assay, the PBMCs exhibited a significant (p

Authors: Yang G, Yang C, She Y, Shen Z, Gao P Abstract Recent studies showed that long non-coding RNAs (lncRNAs) could play critical roles in tumors progression. However, the performance of LINC01354 is still limited in non-small cell lung cancer (NSCLC). In the current study, our results showed that LINC01354 was significantly increased in NSCLC tissues and cell lines. High LINC01354 expression was associated with advanced TNM stage and poor prognosis in NSCLC patients. Loss-of-function assays revealed that knockdown of LINC01354 reduced lung cancer cells proliferation and invasive ability in vitro. Subsequently, ...

Authors: Palussière J, Catena V, Lagarde P, Cousin S, Cabart M, Buy X, Chomy F Abstract Non-small cell lung cancer (NSCLC) remains the leading cause of cancer death; percutaneous thermal ablation (TA) has proven feasibility, good local control and good tolerance in stage I tumors for patients with medical comorbidities and who are ineligible for surgery. In this context, stereotactic body radiotherapy (SBRT) has demonstrated high efficacy in treating T1 NSCLC and will need to be compared with percutaneous ablation. TA is also indicated in oligoprogressive disease; and can be proposed as a salvage treatment o...

Authors: Ichihara E, Miyahara N, Maeda Y, Kiura K Abstract Systemic therapy for advanced non-small cell lung cancer (NSCLC) has dramatically changed in the latest 15 years. Molecular-targeted therapy has brought about an era of precision medicine, and immune checkpoint inhibitors have brought hope for a cure for advanced NSCLC. In the wake of this remarkable advancement, lung cancer with comorbid interstitial pneumonia (IP) has been completely left behind, as most clinical trials exclude patients with comorbid IP. IP, especially idiopathic pulmonary fibrosis (IPF), is often accompanied by lung cancer, and acute exa...
