CaMK-II (the (type II) multifunctional Ca2+/CaM-dependent protein kinase) has been implicated in diverse neuronal and non-neuronal functions, including cell growth control. CaMKII expression was evaluated in a variety of human tumor cell lines using RT-PCR (reverse transcriptase coupled polymerase chain reaction). PCR primers which flanked the CaMK-II variable domain were used so that all possi...

We have investigated the regulation of key human iron binding proteins in mononuclear phagocytes by IFN gamma and iron transferrin. In a previous study, we demonstrated that IFN gamma downregulates the expression on human monocytes of transferrin receptors, the major source of iron for the cell. In the present study, we show that IFN gamma also downregulates the intracellular concentration of f...

Substantial increases in the concentrations of the excitotoxin and N-methyl-D-aspartate-receptor agonist quinolinic acid (QUIN) occur in human patients and non-human primates with inflammatory diseases. Such increases were postulated to be secondary to induction of indoleamine 2,3-dioxygenase in inflammatory cells, particularly macrophages, by interferon-gamma. To test this hypothesis, human pe...

Gamma frequency rhythms have been implicated in numerous studies for their role in healthy and abnormal brain function. The frequency band has been described to encompass as broad a range as 30-150 Hz. Crucial to understanding the role of gamma in brain function is an identification of the underlying neural mechanisms, which is particularly difficult in the absence of invasive recordings in mac...

Interferon-gamma (IFN-gamma) has been reported to antagonize the stimulatory effect of various conditioned media on the growth of normal hematopoietic progenitor cells and clonogenic blasts from patients with chronic myelogenous leukemia (CML) and acute myeloblastic leukemia (AML). In the present study, using purified recombinant cytokines and homogenous cell populations, we provide evidence fo...

BACKGROUND The temporal lobe in conjunction with the hippocampus is responsible for memory processing. The gamma wave is involved with this process. To develop a human brain protocol, a better understanding of the relationship between gamma and long-term memory is vital. OBJECTIVE A more comprehensive understanding of the human brain and specific analogue waves it uses will support the develo...
