Anabolic action of parathyroid hormone regulated by the β2-adrenergic receptor.

abstract：:Fas is a cell surface death receptor that regulates peripheral tolerance and lymphoid homeostasis. In many pathologic conditions, ectopic Fas activation mediates tissue destruction. Several proteins that can bind to the cytoplasmic death domain of Fas have been implicated in Fas signal transduction. Here we show that ...
