Individuals >65 years old account for a large proportion of cancer patients, and usually have poor prognoses due to relative weaker physiological function and lower drug tolerance. To characterize the efficacy and safety of dendritic cell (DC)-activated cytokine-induced killer cell (CIK)-mediated treatment, and develop an adoptive immunotherapy for cancer patients >65 years old, a retrospective study was performed in 58 cancer sufferers who received 1-4 cycles of DC-activated CIK (DC-CIK) treatment and evaluated the response (tumor remission rate) and toxicity (side effects to the treatment)...

OBJECTIVE: Long-term prognosis of hepatocellular carcinoma (HCC) remains poor owing to the lack of treatment options for advanced HCC. Cytokine-induced killer (CIK) cells are ex vivo expanded T lymphocytes expressing both NK- and T-cell markers. CIK cell therapy alone is insufficient for treating advanced HCC. Thus, this study aimed to determine whether treatment with CIK cells combined with valproic acid (VPA) could provide a synergistic effect to inhibit tumor growth in a mouse model of HCC...

With the development of chemotherapy and hematopoietic stem cell transplantation (HSCT), the prognosis of leukemia patients has been improved greatly in the past few decades. However, relapsed and refractory leukemia is still the major cause of mortality in leukemia patients. Besides, advancing age, poor performance status and severe co-morbidities limit the applicability of cytotoxic chemotherapy in certain groups of leukemia patients. Novel agents including nucleoside analogues, kinase inhibitors targeting oncoproteins and monoclonal antibodies are under investigation for the management of leukemia...

Tumor cells are inhibited effectively by As2O3in vitro and in vivo, although the underlying immune regulatory mechanisms remain unknown. Regulatory T cells play a key role in tumor immune escape. In the present study, we aimed to assess the in vivo effects of As2O3 on the immune status in hepatic cancer and its in vitro regulatory role in cytokine-induced killers(CIKs)cytotoxicity. In a tumor H22 xenograft model of hepatic cancer, we demonstrated that As2O3 treatment decreased tumor volumes and weights, and improved survival by reducing Tregs infiltration into the tumor...

The extracellular pH is lower inside solid tumors than in normal tissue. The acidic environment inhibits the cytotoxicity of lymphocytes in vitro and promotes tumor cell invasion. In the present study, both in vitro and in vivo experiments were conducted to investigate how NaHCO3 would affect the antitumor activities of cytokine-induced killer (CIK) cells against hepatocellular carcinoma (HCC) cells. For the in vitro experiments, HepG2 cells were cultured at pH 6.5 and 7.4 in the presence of CIK cells or CIK cell-conditioned medium (CMCIK)...

BACKGROUND: Ayurved Siriraj Wattana recipe (AVS073), has been prescribed as tonic, to increase appetite, and for pain relief. It also exhibits antioxidant, anti-inflammatory, immunomodulating and anti-cancer activities. However, the immunomodulatory effects on antigen-presenting cells and effector T cells remained elusive. We thus aimed to study the effects of AVS073 on differentiation, maturation, functions and proportions of CIK cells and monocyte-derived DCs. METHODS: CIK cells and monocyte-derived DCs were treated with AVS073, followed by the assessment of T-helper (Th) phenotypes using real-time RT-PCR and flow cytometry...

Adoptive immunotherapy using cytokine-induced killer (CIK) cells has shown potential antitumor ability against several kinds of cancers, including melanoma. However, little is known about the achievable outcome of CIK cells in melanoma patients at different pathological stages. Here we recruited 55 patients treated with conventional therapy plus CIK cells as the CIK group, and 49 patients treated with conventional therapy alone as the control group. The pathological characteristics were comparable between two groups, with a follow-up period up to 40 months...

Cytotoxicity of cytokine-induced killer (CIK) cells depends mainly on their encounters with target cells, but how many CIK cells are required to kill an individual cancer cell is unknown. Here we used time-lapse imaging to quantify the critical effector cell number required to kill an individual target cell. CIK cells killed MHC-I-negative and MHC-I-positive cancer cells, but natural killer (NK) cells destroyed MHC-I-negative cells only. The average threshold number of CIK cells required to kill an individual cancer cell was 6...

Cytokine induced killer (CIK) cells have a powerful tumor cells killing activity both in vitro and in vivo and transfusion of these cells have become an adjuvant treatment for tumors. CIK cells are induced and amplified from peripheral blood mononuclear cells (PBMCs) with multiple cytokines. As CD4(+)CD25(bri) regulatory T cells can be also induced by high dose of interleukin 2 (IL-2) which is used for CIK cells amplification in the CIK cell culture system, the anti-tumor activity of CIK cells was suppressed to some extent...

Patients with hepatocellular carcinoma (HCC), a fatal cancer, have benefited significantly from TACE (transcatheter arterial chemoembolization) and immunotherapy treatments. Immunotherapy that includes dendritic cells and cytokine-induced killer cells (DC-CIK) in combination with TACE has been extensively applied in cases of HCC. Few decisive conclusions about these combined effects on the outcomes of HCC patients have been reached. Therefore, the present meta-analysis was performed to compare the efficacy of the combined usage of DC-CIK with TACE with a TACE therapy alone on the outcomes of HCC patients...

Cytokine-induced Killer (CIK) cells are a heterogeneous population of ex vivo expanded T lymphocytes capable of MHC-unrestricted antitumor activity, which share phenotypic and functional features with both NK and T cells. Preclinical data and initial clinical studies demonstrated their high tolerability in vivo, supporting CIK cells as a promising cell population for adoptive cell immunotherapy. In this study, we report for the first time that CIK cells display a donor-dependent expression of CD16, which can be engaged by trastuzumab or cetuximab to exert a potent antibody-dependent cell-mediated cytotoxicity (ADCC) against ovarian and breast cancer cell lines, leading to an increased lytic activity in vitro, and an enhanced therapeutic efficacy in vivo...
