Memory-likeCD8+ T cells [32] andsuppressive CD8+CD44+CXCR3+ T cells [17] are likely to exist in the human organism.Thus, the adoptive transfer aimed at restoring the count of immune cells inperipheral organs can lead to clinically unfavorable outcomes: i.e., a weakerresponse to antigens and, hence, increased predisposition or vulnerability toinfectious diseases. The gene discussed is CD8A; the disease is glycogen storage disease VI.
