To our knowledge, this is the first description of TLR-4 urothelial expression hormonal modulation. The described castration-mediated immunomodulation will help to improve the knowledge of urothelial cancer gender diversities and PRRs modulations with treatment implications.

After treatment with MNU, the rats were distributed into four experimental groups: Control (without MNU) group, MNU (cancer) group, MNU-BCG (Bacillus Calmette-Guerin) group, and MNU-P-MAPA group...These alterations were fundamental for histopathological recovery from cancer and for suppress abnormal cell proliferation. This action of P-MAPA on apoptotic pathways may represent a new strategy for treating NMIBC.

The new modalities for treating patients with high-grade non-muscle invasive bladder cancer (HGNMIBC) for whom Bacillus Calmette-Guerin (BCG) has failed or is contraindicated are recently increasing due to the development of new drugs...Immunohistochemical analysis demonstrated that while the conventional BCG treatment stimulated the canonic pathway, OncoTherad® (MRB-CFI-1) stimulated the non-canonical pathway (increasing expression of TLR4, TRIF, IRF, and IFNγ). OncoTherad® (MRB-CFI-1) could be considered a promising therapy in the treatment of NMIBC.
