Web12 apr. 2024 · Summary Cytotoxic T Lymphocytes (CTLs) control tumours via lysis of antigen presenting targets, or through secretion of cytokines such as interferon-γ (IFNG) which inhibit tumour cell proliferation. Improved understanding of CTL interactions within solid tumours will aid the development of immunotherapeutic strategies against cancer. IFNγ up-regulates antigen presentation on epithelial cells. To determine whether in our model IFNγ was acting directly on CTL or on targets, we pre-treated CTL with IFNγ. OVA-primed CTL were treated for 4 h with rIFNγ, and then co-cultured with KC and imaged for 30 h. CTL pre-stimulated with rIFNγ killed … Meer weergeven Rejection of antigen-expressing skin grafts is a model of CTL-dependent immunopathology.
