Colorectal cancer (CRC) is the second leading cause of cancer-related death worldwide. Cytokine-induced killer (CIK) cells are an adoptive immunotherapy reported to have strong anti-tumour activity across a range of cancers. They are a heterogeneous mix of lymphoid cells generated by culturing human peripheral blood mononuclear cells with cytokines and monoclonal antibodies in vitro. In this study, we investigated the yield and function of CIK cells generated from patients with CRC liver metastases. We first showed that CIK cells generated in serum free medium X-VIVO 15 were comparable to those from RPMI medium with 10% FBS in terms of the number and percentages of the main subsets of cells in the CIK culture, and the intracellular levels of granzyme B and perforin, and the pro-inflammatory cytokines IL-2, IFN-γ and TNF-α. The CIK cells were cytotoxic to CRC cell lines grown in 2D cultures or as spheroids, and against autologous patient-derived tumour organoids. Donor attributes such as age, sex, or prior chemotherapy exposure had no significant impact on CIK cell numbers or function. These results suggest that functional CIK cells can be generated from patients with CRC liver metastatic disease, and support further investigations into the therapeutic application of autologous CIK cells in the management of patients with CRC liver metastases.

Tumors frequently evade immune destruction by impairing cytotoxic CD8 T-cell responses, highlighting the need for strategies that restore T-cell functionality. Here, we identify SLAMF7 (CD319) as a key enhancer of human CD8 T-cell responses against tumors. SLAMF7 expression is induced by pro-inflammatory signals such as IL-12 and CD28 co-stimulation.

Although checkpoint immunotherapy has primarily focused on CD8⁺ T cells, emerging evidence highlights an important role for cytotoxic CD4⁺ T cells in mediating therapeutic responses. However, research on the functional properties of cytotoxic CD4⁺ T cells in the context of immunotherapy is still at an early stage and remains insufficiently defined. Utilizing single-cell RNA-sequencing datasets obtained from metastatic melanoma patients treated with checkpoint inhibitors targeting PD-1 and/or CTLA-4, we performed transcriptomic profiling of conventional CD4⁺ T cells, excluding proliferative and regulatory (FOXP3⁺) subsets, and compared responders and non-responders as distinct groups.

Non-small cell lung cancer (NSCLC) remains a leading cause of cancer-related mortality worldwide, with only modest improvements in survival despite advances in conventional therapies. Cell-based immunotherapy, which utilizes ex vivo expanded or genetically modified immune cells, has emerged as a promising therapeutic alternative. Approaches such as natural killer (NK) cells, tumor-infiltrating lymphocytes (TILs), dendritic cell (DC)-based vaccines, cytokine-induced killer (CIK) cells, and chimeric antigen receptor T (CAR-T) cells have shown encouraging potential in preclinical and early clinical studies.

A previous study in our laboratory revealed that microRNA-33 (miR-33) regulated autophagy initiation and inflammatory response by targeting Atg5; furthermore, in this study, chloroquine (CQ), lipopolysaccharide (LPS) and the miR-33 inhibitor were transfected into Ctenopharyngodon idella kidney (CIK) cells to explore whether miR-33 regulated late-stage autophagy and inflammatory response induced by LPS. The results showed that CQ inhibited the fusion of autophagosome and lysosome and significantly increased the secretion of pro-inflammatory cytokines (p < 0.05).

Viruses use a range of sophisticated strategies to evade detection by cytotoxic T-lymphocytes (CTLs) within host cells. Beyond elaborating dedicated viral proteins that disrupt the MHC class I antigen-presentation machinery, some viruses possess intrinsic, cis-acting genome-encoded elements that interfere with antigen processing and display. These protein features, including G-quadruplex motifs, repetitive peptide sequences, and rare-codon usage, counterintuitively limit production of proteins critical to virus survival, particularly during latency.
