Hypothesis

Can Mycobacterium indicus pranii (MIP) activate anti-tumor immune responses in tumor-bearing mice?

Conclusion

MIP therapy is effective in protecting mice from tumor by activating immune cells and reducing regulatory T cells.

Supporting Evidence

  • MIP treatment delayed tumor growth and reduced tumor volume in mice.
  • MIP-treated mice showed higher infiltration of immune cells in tumors.
  • The percentage of regulatory T cells was lower in MIP-treated mice compared to controls.
  • MIP therapy improved survival rates in tumor-bearing mice.

Takeaway

Researchers found that a treatment using a type of bacteria helped mice fight tumors better by boosting their immune system.

Methodology

B16F10 melanoma cells were injected into mice, and the effects of MIP treatment on tumor growth and immune response were evaluated.

Potential Biases

Potential bias in animal model selection and treatment administration.

Limitations

The study was conducted in mice, and results may not directly translate to humans.

Participant Demographics

C57BL/6 mice, 6-8 weeks old.
