Spheroid glioblastoma culture conditions as antigen source for dendritic cell-based immunotherapy: spheroid proteins are survival-relevant targets but can impair immunogenic interferon γ production.
Pretreatment with BTZ further increased stress-ligands, induced TRAIL-R2 expression and enhanced GBM lysis to 33-76% through augmented IFNγ release (<i>p</i> < 0.05).
Univariate analysis indicated that the combination of three cytokines (IL-4/IL-5/IL-6, p = .0022; IFN-γ/TNF-α/IL-17A, p = .0083) but not a 'partial' combination of these cytokines, the IFN-γ immune response to EBV-EBNA-1 (p < .0001) as well as T-cell responses to the survivin<sub>97-111</sub> peptide (p = .0152) correlated with longer survival among patients with GBM.
Using CTL of GBM patients stimulated with GBM lysate-pulsed DCs increased IFN-γ messenger RNA levels, and intracellular IFN-γ protein expression was positively correlated with specificity against GBM antigens.
EGFR-CAR-engineered NK cells displayed enhanced cytolytic capability and IFN-γ production when co-cultured with GB cells or patient-derived GB stem cells in an EGFR-dependent manner.
The present investigation was designed to unravel the molecular mechanisms of the inhibition of cell proliferation, migration, and invasion of human glioblastoma SNB-19 and LN-18 cell lines after knockdown of hTERT using a plasmid vector based siRNA and concurrent treatment with IFN-gamma.
In this study, we examined the inhibitory effect of IFNgamma on hypoxia-induced CXCR4 gene expression in human glioblastoma cell lines and explored the mechanism of inhibition.
We investigated the possibility of modulation of signal transduction pathways for induction of apoptosis in human glioblastoma T98G (PTEN-harboring) and U87MG (PTEN-deficient) cell lines after treatment with the combination of all-trans retinoic acid (ATRA) and interferon-gamma (IFN-gamma).
T98G glioblastoma cells were cultured with cytokines (interferon-gamma 100 U/ml, tumor necrosis factor-alpha 20 ng/ml and interleukin-1beta 10 ng/ml) under normoxia or hypoxia (1% O(2)).
Northern blot analysis showed that treatment with interferon-gamma and with interleukin-1beta for 24 h decreased the expression levels of heme oxygenase-1 mRNA to approximately 20 and approximately 50% of the control levels, respectively, in a human glioblastoma cell line, T98G.
By using human fibroblasts, human glioblastoma cell line A172 and monocytes, we investigated the signal-transduction mechanism for IFN-gamma-induced synthesis of C2 and factor B.
Modulation of proliferation and antigen expression of a cloned human glioblastoma by interleukin-4 alone and in combination with tumor necrosis factor-alpha and/or interferon-gamma.
Interferon gamma induces class II expression in this glioblastoma cell line and, in parallel, up-regulates X1 and X2 box protein-DNA interactions, while all other interactions remain unchanged.
The results of the present study indicate that multidrug-resistant human glioblastoma multiforme cells retain their increased sensitivity to the antiproliferative activity of the combination of IFN-beta plus IFN-gamma, and differences in antigenic phenotype are apparent in independent multidrug-resistant glioblastoma multiforme clones.
