Expression and Function of Fas on Cells

Functional expression of Fas antigen (CD95) on hematopoietic progenitor cells.

We investigated the expression of an apoptosis-associated antigen (Fas) (CD95) on hematopoietic progenitor cells in the presence or absence of interferon-gamma (IFN-gamma) and/or tumor necrosis factor-alpha (TNF-alpha). CD34+ cells freshly isolated from bone marrow did not express Fas. However, IFN-gamma and/or TNF-alpha induced the expression of both the mRNA of Fas and Fas itself in a dose-de...

‏‎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...

expression of fas antigen (cd95) on human leukemic cells and assessment of apoptosis on fas+ and fas-samples by flowcytometry method

regulation of normal cell growth and turnover is balanced between cell pro¬liferation, cell differentiation and apoptosis. a disruption of this balance is thought to be an important event leading to carcinogenesis .one of the effector molecules in apoptosis is fas antigen . cross-linking of fas by its ligand (fas l) or agonistic anti fas antibodies induces apoptosis of cells expressing fas on t...

Differential regulation and function of Fas expression on glial cells.

Fas/Apo-1 is a member of the TNF receptor superfamily that signals apoptotic cell death in susceptible target cells. Fas or Fas ligand (FasL)-deficient mice are relatively resistant to the induction of experimental allergic encephalomyelitis, implying the involvement of Fas/FasL in this disease process. We have examined the regulation and function of Fas expression in glial cells (astrocytes an...
