Chemomodulation of human dendritic cell function by antineoplastic agents in low noncytotoxic concentrations

Chemotherapeutic agents in noncytotoxic concentrations increase antigen presentation by dendritic cells via an IL-12-dependent mechanism.

Antineoplastic chemotherapeutic agents may indirectly activate dendritic cells (DCs) by inducing the release of "danger" signals from dying tumor cells. Whereas the direct cytotoxic or inhibitory effect of conventional chemotherapy on DCs has been reported, modulation of DC function by chemotherapeutic agents in low noncytotoxic concentrations has not yet been investigated. We have tested the e...

‏‎interpersonal function of language in subtitling

‏‎translation as a comunicative process is always said to be associated with various aspects of meaning loss or gain. subtitling as a mode of translating, due to special discoursal and textual conditions imposed upon it, is believed to be an obvious case of this loss or gain. presenting the spoken sound track of a film in writing and synchronizing the perception of this text by the viewers with...

Suppression of influenza A virus replication in human lung epithelial cells by noncytotoxic concentrations bafilomycin A1.

Subcellular trafficking within host cells plays a critical role in viral life cycles, including influenza A virus (IAV). Thus targeting relevant subcellular compartments holds promise for effective intervention to control the impact of influenza infection. Bafilomycin A1 (Baf-A1), when used at relative high concentrations (≥10 nM), inhibits vacuolar ATPase (V-ATPase) and reduces endosome acidif...

Low Noncytotoxic Concentrations of 5-Fluorouracil Have No Adverse Effects on Maturation and Function of Bone Marrow-Derived Dendritic Cells in vitro: A Potentially Safe Adjuvant for Dendritic Cell-Based Cancer Therapy.

BACKGROUND Low, noncytotoxic concentrations of various chemotherapeutic drugs like 5-fluorouracil (5-FU) induce antitumor immune responses by selectively depleting tumor-induced immunosuppressive cells, and could therefore be used in combination with dendritic cell (DC) vaccines in order to enhance their immunotherapeutic efficacy. However, the likely negative influences of low, noncytotoxic do...
