Abstract

Recently, with the rapid development of elucidating the tumor immunological status, it has become clear that various lymphocytes, which are infiltrating tumor, are deeply involved in not only tumor growth but also its elimination. The interest and importance of cytotoxic T cells(CTLs)for cancer immunotherapy has been further increased, since CTLs play an important role in eliminating cancer cells by having high cytotoxic activity and high proliferation ability. To achieve potent antitumor effects, in addition to the anti-tumor immune response induced by various methods such as cancer peptide vaccine and immune checkpoint inhibitor, it is thought to be essential that CTLs should migrate and invade into localized cancer tissues. In this article, we will introduce the latest immunotherapies related to CTLs infiltration, and various methods to enhancement of CTLs infiltration into the cancer tissues.

Cell Checkpoints & Regulators

Cell cycle checkpoints are a series of complex checkpoint mechanisms that detect DNA abnormalities and ensure that DNA replication and repair are complete before cell division. They are primarily regulated by cyclins, cyclin-dependent kinases, and the anaphase-promoting complex/cyclosome. Here is the latest research.

Cancer Vaccines

Cancer vaccines are vaccines that either treat existing cancer or prevent development of a cancer.
