    The Role of CD8+ T Cell Clones in Immune Thrombocytopenia

    Researchers found that adults with chronic immune thrombocytopenia had increased polyfunctional, terminally differentiated effector memory (TEMRA) CD8+ T cells expressing intracellular interferon-g, tumor necrosis factor-a, and Granzyme B defining them as TEMRA cells.
