The gamma genes provide the major contribution to beta-like globin chain production in the fetal liver of humans. However, the expression of gamma genes in the fetus is a recent evolutionary trend seen only in the primate lineage. In a previous study, it was shown that galago and human gamma genes retain their characteristic stage-specific expression patterns in transgenic mice (galago gamma is...

Neuronal gamma-band (30-100 Hz) synchronization subserves fundamental functions in neuronal processing. However, different experimental approaches differ widely in their success in finding gamma-band activity. We aimed at linking animal and human studies of gamma-band activity and at preparing optimized methods for an in-depth investigation of the mechanisms and functions of gamma-band activity...

Two monoclonal antibodies directed against distinct epitopes of recombinant human immune interferon (rIFN-gamma) were used to investigate the relationship between the molecular organization of IFN-gamma and its various biological activities on cultured human melanoma cells. Both monoclonal antibodies inhibited the increase in the expression of cell surface human lymphocyte antigens Class I and ...

It has been previously reported that inhibition of human erythroid colony-forming units (CFU-E) in vitro by interleukin-1 (IL-1) is an indirect effect, occurring through the production of interferon gamma (IFN gamma). IFN gamma, in turn, inhibits CFU-E colony formation directly, and its inhibitory effect can be overcome by exposure to high concentrations of erythropoietin (EPO). To develop an i...
