Recent data have demonstrated that mutations in the receptor for neurokinin B (NKB), the NK-3 receptor (NK3R), produce hypogonadotropic hypogonadism in humans. These data, together with reports that NKB expression increases after ovariectomy and in postmenopausal women, have led to the hypothesis that this tachykinin is an important stimulator of GnRH(More)
There is now considerable evidence that dynorphin neurons mediate the negative feedback actions of progesterone to inhibit GnRH and LH pulse frequency, but the specific neurons have yet to be identified. In ewes, dynorphin neurons in the arcuate nucleus (ARC) and preoptic area (POA) are likely candidates based on colocalization with progesterone receptors.(More)
OBJECTIVE We have shown in vitro and in vivo that osteoclast maturation requires calcium-release activated calcium (CRAC) channels. In inflammatory arthritis, osteoclasts mediate severe and debilitating bone erosion. In the current study, we assess the value of CRAC channels as a therapeutic target to suppress bone erosion in acute inflammatory arthritis.(More)
