An important function of the sympathetic nervous system is to maintain homeostasis by modulating the level of cellular activity in many diverse organ systems. The sympathetic neurotransmitter norepinephrine modulates the level of T and B lymphocyte activity by binding to the beta2-adrenergic receptor (beta2AR). The present study was designed to elucidate(More)
Testosterone, after conversion to estrogen, masculinizes the developing preoptic area (POA) of rats, via binding to intracellular estrogen receptors located within the POA. Our previous studies have shown what seems to be a paradox, in that the levels of estrogen receptor mRNA are lower in males than in females. In the present study, we examined the effects(More)
We recently reported that resting clones of murine Th1 cells, but not resting Th2 cells, expressed a detectable level of the beta-2-adrenergic receptor (beta 2AR). In the present study, we proposed that the level of beta 2AR expression on anti-CD3 mAb-activated CD4+ effector Th cells may differ from the level on resting cells, and that a change in receptor(More)
We have recently demonstrated that 17 beta-estradiol (E2) inhibits peritoneal adhesion formation. Because macrophages play a central role in inflammation and wound healing, we chose to investigate whether the E2 could inhibit the expression of JE, the murine monocyte chemoattractant protein-1 (MCP-1). To accomplish this, murine fibroblasts were cultured(More)
We recently showed that clones of Th1 cells, but not Th2 cells, expressed a functional beta-2-adrenergic receptor (beta2AR) and that either norepinephrine or the beta2AR agonist terbutaline stimulated this receptor to modulate the level of Th1 cytokines produced. In the present study, we show that norepinephrine and terbutaline stimulate the beta2AR to(More)
