We have disabled TNF receptor (TNFR) function by inducing allosteric modulation of tryptophan-107 (W107) in the receptor. The allosteric effect operates by means of an allosteric cavity found a short distance from a previously identified loop involved in ligand binding. Occupying this cavity by small molecules leads to perturbation of distal W107 and disables functions of the TNFR, a molecule n...
Angiotensin II (Ang II) plays an important role in post-myocardial infarction (MI) remodeling. Most Ang II effects related to remodeling involve activation of the type 1 receptor (AT(1)). Although the AT(1) receptor is upregulated on cardiac fibroblasts post-MI, little is known about the mechanisms involved in the process. Consequently, we tested whether growth factors known to be present in th...
Protein kinase C (PKC) triggers cellular signals that regulate proliferation or death in a cell- and stimulus-specific manner. Although previous studies have demonstrated that activation of PKC with phorbol 12-myristate 13-acetate (PMA) protects cells from apoptosis induced by a number of mechanisms, including death receptor ligation, little is known about the effect or mechanism of PMA in the ...
tumor necrosis factor- α (tnf-α) plays an important role in diverse cellular events such as septic shock, induction of other cytokines, cell proliferation and apoptosis. tumor necrosis factor (tnf)-related apoptosis-inducing ligand (trail) is currently attracting great interest as a potential anticancer drug. trail could selectively induce apoptosis in tumor cells in vitro and in vivo by a deat...

Proinflammatory state of the brain increases the risk for seizure development. Neonatal Borna disease virus (BDV)-infection of mice with neuronal overexpression of tumor necrosis factor-α (TNF) was used to investigate the complex relationship between enhanced cytokine levels, neurotropic virus infection and reaction pattern of brain cells focusing on its role for seizure induction. Viral antige...
Polymorphonuclear leukocytes (PMN) residing on biologic surfaces respond with a vigorous respiratory burst when exposed to tumor necrosis factor alpha (TNF). PMN possess both the p55 and the p75 TNF receptors, but their role in the elicitation of the respiratory burst is not known. We addressed this problem by studying the effect of monoclonal antibodies (MoAbs) directed against the p55 TNF rec...
OBJECTIVE P2 receptors have been implicated in the release of neurotransmitter and pro-inflammatory cytokines due to their response to neuroexcitatory substances in the microglia. Dorsal horn P2Y12 and P2Y13 receptors are involved in the development of pain behavior induced by peripheral nerve injury. However, it is not known whether P2Y12 and P2Y13 receptors activation is associated with the e...
