Natural killer (NK) cells have been implied in the resistance against certain tumors and
virally-infected cells. The prognostic significance of tumor infiltrating NK cells in primary …

Objective: Natural cytotoxicity caused by mediated natural killer cells is believed to play an
important role in host-cancer defense mechanisms. Immunohistochemically, we have …

BACKGROUND. Despite natural killer (NK) cells being originally identified and named
because of their ability to kill tumor cells in vitro, only limited information is available on NK …

Background: Natural killer (NK) cells are important effector cells in the defense against
tumors. The present study retrospectively examines the intratumoral NK cells in primary …

BACKGROUND Natural killer (NK) cells are a group of effector cells that act nonspecifically
against tumor cells. The correlation between intratumoral NK cell infiltration and …

BACKGROUND Natural killer (NK) cells have a spontaneous cytotoxic capacity against
tumor cells. These cells represent a small proportion of human colon carcinoma‐infiltrating …

BACKGROUND Natural cytotoxicity mediated by natural killer (NK) cells is believed to play
an important role in host anticancer defense mechanisms. The aim of this study was to …

Even though the lung represents a special immune compartment with the capacity of a high
inflammatory response, ineffective anti-tumour immunity is common in lung-associated …

Purpose One of the key immune cells involved in the pathogenesis of lung cancer is natural
killer (NK) cells and these cells are novel targets for therapeutic applications in lung cancer …

OBJECTIVE: Natural cytotoxicity, mediated by natural killer (NK) cells, has been believed to
play an important role in inhibiting experimental tumor metastasis, and diminished NK cell …
