Blocking IL-10 enhances bacillus Calmette-Guérin induced T helper Type 1 immune responses and anti-bladder cancer immunity

چکیده

Proper induction of Th1 immunity is required for effective immunotherapy of bladder cancer with the bacillus Calmette-Guérin (BCG). Interleukin-10 (IL-10) downregulates the Th1 immune response and is associated with BCG therapy failure. We evaluated BCG plus IL-10 blocking antibodies and found that this combination therapy induces enhanced Th1 immune responses and anti-bladder cancer immunity in preclinical animal models.

Role of IL-10 in Urinary Bladder Carcinoma and Bacillus Calmette-Guerin Immunotherapy

Problem statement: Bladder cancer is a common urologic cancer and intravesical Mycobacterium bovis Bacillus Calmette-Guerin (BCG) is the mainstay in the treatment of superficial bladder cancer. However, the current BCG therapy is not desirable with respect to its efficacy and side effects. Interleukin (IL)-10, a T helper type (Th) 2 cytokine, plays an important regulatory role in bladder cancer...

IFN-alpha 2B enhances Th1 cytokine responses in bladder cancer patients receiving Mycobacterium bovis bacillus Calmette-Guérin immunotherapy.

Combination therapy with intravesical bacillus Calmette-Guérin (BCG) plus IFN-alpha for superficial bladder cancer has been demonstrated to be more effective than either single agent alone in animal studies and of suggested greater efficacy in clinical studies. However, the mechanism by which IFN-alpha enhances BCG-mediated antitumor activity is poorly understood. Using PBMCs from bladder cance...

Neutrophil granulocytes are required for effective Bacillus Calmette-Guérin immunotherapy of bladder cancer and orchestrate local immune responses.

The role of polymorphonuclear neutrophil granulocytes (PMN) in antitumoral immune responses displays a striking dichotomy. Under inflammatory conditions, PMN may promote tumor growth and progression. In contrast, especially in the context of therapeutic interventions, PMN can exert important antitumor functions. However, until now, the mechanisms of PMN-mediated activation of tumor immunity are...

Th1 Cytokine-Secreting Recombinant Mycobacterium bovis Bacillus Calmette-Guérin and Prospective Use in Immunotherapy of Bladder Cancer

Intravesical instillation of Mycobacterium bovis bacillus Calmette-Guérin (BCG) has been used for treating bladder cancer for 3 decades. However, BCG therapy is ineffective in approximately 30-40% of cases. Since evidence supports the T helper type 1 (Th1) response to be essential in BCG-induced tumor destruction, studies have focused on enhancing BCG induction of Th1 immune responses. Although...

Early Secreted Antigen ESAT-6 of Mycobacterium tuberculosis Promotes Protective T Helper 17 Cell Responses in a Toll-Like Receptor-2-dependent Manner

Despite its relatively poor efficacy, Bacillus Calmette-Guérin (BCG) has been used as a tuberculosis (TB) vaccine since its development in 1921. BCG induces robust T helper 1 (Th1) immune responses but, for many individuals, this is not sufficient for host resistance against Mycobacterium tuberculosis (M. tb) infection. Here we provide evidence that early secreted antigenic target protein 6 (ES...
