Answer #1

The right answer is "false".

Explanation .

PD-L1 or Programmed Cell Death Ligand 1 expressed on the tumor cells which bind to the PD-1 or Programmed Cell Death Protein 1 receptor presented in the activated T-cell which results to the inhibition of cytotoxic T-cell. These deactivated T-cells remain inhibited in the tumor micro environment .

Besides the existence of tumor-specific T cells and B cells, many studies have demonstrated that high numbers of tumor-infiltrating lymphocytes are associated with good clinical outcome. In addition, not only the density but also the organization of tumor-infiltrating immune cells has been shown to determine cancer patient survival. Indeed, more and more studies describe the development within the tumor microenvironment of this anatomic micro-structure, whose presence has a positive impact on tumor prognosis. What is it?
