Immune checkpoint inhibitors and MDSCs

Immune checkpoint inhibitors and MDSCs

The development of immune checkpoint inhibitors (ICIs) targeting lymphoid cells has remarkedly transformed therapeutic approaches for the treatment of cancer. However, response rates to T cell checkpoint inhibitors vary between individuals with some patients showing minimal to no clinical benefit. In these patients, resistance to this immunotherapy may be partly attributed to myeloid- derived suppressor cells (MDSCs), a heterogeneous population of myeloid progenitors and immature myeloid cells that function as immune suppressors.
