NK Cell Subpopulation Is Altered and the Expression of TLR1 and TLR9 Is Decreased in Patients with Acute Lymphoblastic Leukemia

Figure 4

Expression of TLRs 1–5 in cytotoxic NK cells from controls and ALL patients. Representative micrographs of NK cells (red) positive for TLRs 1, 2, 3, 4, and 5 (green) determined in the peripheral blood of controls and patients with ALL and in the bone marrow of patients with ALL. Nuclei were differentiated using DRAQ7 (blue). TLR, toll-like receptor; NK, natural killer; ALL, acute lymphoblastic leukemia.
