Tumor escape and recurrence are major impediments for successful immunotherapy. It is well-documented that the emergence of Ag-loss variants, as well as regulatory mechanisms suppressing T cell function, have been linked to inadequate antitumor activity. However, little is known regarding the role of Fas-mediated cytotoxicity by tumor-specific CD8(+) CTL in causing immune evasion of Fas resista...
Background: Tumor microenvironment is an active factor participating in immunoregulation, thereby preventing immunosurveillance and limiting the efficacy of anticancer therapies. Hypoxia as a major characteristic of solid tumors causes the expression of Hypoxia-Inducible Factor-1α (HIF-1α). This is a transcription factor that mediates hypoxic responses of tumor cells and involves in the express...
Introduction: Human papillomavirus (HPV) 16 E7 protein is expressed constitutively by HPV-infected tumor cells. Mutant versions of E7 are considered as safer candidates for immunotherapy of cervical cancer. Different strategies including formulation with adjuvants are used to induce a potent immune response against antigenic proteins. Methods: In this experimental study, we used Escherichia co...
