rhG-CSF does not affect the phenotype of adult donor peripheral blood NK cells

Severe autoimmune hyperthyroidism after donation of rhG-CSF-primed allogeneic peripheral blood progenitor cells

Conditioned Medium from Cultured Colorectal Cancer Cells Affects Peripheral Blood Mononuclear Cells Inflammatory Phenotype in Vitro

Background: Colorectal cancer (CRC) is the third most common cancer worldwide. Studies have indicated that immune cells and soluble factors play a key role in maintaining the balance between tumor-promoting inflammation and anti-tumor immunity. It has been shown that secreted cytokines from CRC cell lines could affect peripheral blood mononuclear cells (PBMCs), monocytes, and macrophages phenot...

P33. NK-92 cellular immunotherapy as an alternative to donor derived peripheral blood NK cells

Methods Collecting NK cells form donors requires them to undergo leukapheresis with subsequent removal of CD3+ lymphocytes (to prevent GvHD) and expansion and activation of the NK cell enriched fraction with IL-2. In contrast, the continuously growing NK cell line NK-92 can be easily expanded to clinical scale in bioreactors. The broad cytotoxicity of NK-92 is due to the lack of most of the KIR...

Modulation of T-bet and Eomes during Maturation of Peripheral Blood NK Cells Does Not Depend on Licensing/Educating KIR

Peripheral natural killer (NK) cells upregulate T-bet and downregulate Eomes, the key transcription factors regulating NK cell maturation and function during the last maturation steps toward terminally differentiated effector cells. During this process, NK cells acquire killer immunoglobulin-like receptors (KIR) and effector functions, such as cytotoxicity and target cell-induced cytokine produ...

Conversion of peripheral blood NK cells to a decidual NK-like phenotype by a cocktail of defined factors.

NK cells that populate the decidua are important regulators of normal placentation. In contrast to peripheral blood NK cells, decidual NK (dNK) cells lack cytotoxicity, secrete proangiogenic factors, and regulate trophoblast invasion. In this study we show that exposure to a combination of hypoxia, TGF-β1, and a demethylating agent results in NK cells that express killer cell Ig-like receptors,...
