Temperature-dependent dielectric and viscosity studies have been carried out in two samples of crude oils procured from different wells of Oman oil fields. The dielectric permittivity is found to decrease linearly with increasing temperature for both

Activation-induced cell death (AICD) is initiated by the TCR-dependent up-regulation of Fas ligand (FasL) mRNA. The subsequently generated soluble or cell-associated FasL gene products bind Fas, leading to apoptosis of the T cells. Although TCR stimu

Degranulation of eosinophils and release of toxic granule proteins play key roles in allergic diseases such as bronchial asthma. However, the intracellular signaling mechanisms that trigger eosinophil degranulation remain unclear. In this study, we i

NK cells are a subpopulation of lymphocytes that kill virally infected cells and tumor cells without previous sensitization. Although exposure to distinct cytokines, including IL-2 and IL-12, can enhance these cytotoxic responses, the mechanism of th

Stimulation of human normodense eosinophils with immobilized secretory IgA (sIgA) or IgG, or with the soluble stimulus, FMLP, triggers the exocytotic release of the granule protein, eosinophil-derived neurotoxin (EDN). In this report, we demonstrate

Antibody-dependent cellular cytotoxicity is initiated when low affinity Fc receptors (Fc gamma R type III/CD16) on NK cells bind to sensitized (i.e., antibody coated) target cells. Fc gamma R cross-linkage induces the activation of phospholipase C (P

Stimulation of activated T lymphocytes with interleukin 2 (IL-2) results in rapid increases in intracellular protein tyrosine phosphorylation. Both the identity of the protein tyrosine kinase (PTK) activated by IL-2 receptor ligation and the identiti

We have investigated the effects of cAMP on Ig-induced human eosinophil activation. Stimulation of human normodense eosinophils with IgG- or secretory IgA (sIgA)-coated Sepharose beads induced cellular degranulation, as measured by the release of the

NK cells can mediate either FcR-dependent cytotoxicity against antibody-coated target cells or direct cytotoxicity against a variety of tumor cells. We used homogeneous, cloned populations of CD16+/CD3- human NK cells to characterize and compare the

Protein tyrosine kinases play fundamental roles in the transduction of signals that regulate cell growth, differentiation, and functional responses to a diversity of external stimuli. It is therefore likely that understanding protein tyrosine kinase
