The cellullar immune response is important in the containment of progressive multifocal leukoencephalopathy (PML). We examined program cell death-1 (PD-1) expression, a marker of cellular immune exhaustion, on T lymphocytes in PML. PD-1 expression was elevated on total CD4(+) and CD8(+) T cells (med...
