Hypothesis
The study investigates the correlation between class I antigen expression and the ability to generate tumour infiltrating lymphocytes (TILs) from bladder tumour biopsies.
Conclusion
The successful expansion of TILs correlates with the normal expression of class I antigens on the tumour cells.
Supporting Evidence
- TILs were established from six of 19 bladder cancer cases.
- The mean frequency of positive staining for T cell markers was high, indicating activated T cells.
- There was a significant correlation between the expression of class I antigens and the ability to generate TILs.
Takeaway
Doctors looked at bladder cancer samples to see if certain immune cells could grow. They found that these cells grew better when the cancer cells had normal markers.
Methodology
Tissue sections from bladder tumours were analyzed for TIL growth using IL-2 and conditioned medium, and TILs were phenotyped with specific antibodies.
Limitations
The majority of tumour biopsies were not suitable for culturing due to small size or condition.
