Furthermore, social isolation and repeated methamphetamine administration caused significant learning and mnemonic dysfunctions. Treatment with clozapine improved learning and mnemonic ability in

all of the tasks. Pyrilamine treatment ameliorated performance in all the tests examined except for the passive avoidance test. Thioperamide, however, did not change the learning and mnemonic ability. Donepezil, an acetylcholinesterase inhibitor, reversed the learning and mnemonic dysfunction in all four tasks. The present study has shown that blockade of histamine H-1 receptor improved the learning and mnemonic ability in mice, raising the possibility that treatment with clozapine or pyrilamine may improve learning and mnemonic performance in certain patients with psychiatric diseases such as schizophrenic patients with cognitive dysfunction.”
“Translocator protein GDC-0994 mouse (TSPO) present in the outer mitochondrial membrane has been suggested to be critical for cholesterol import, a rate-limiting step for steroid hormone biosynthesis. Despite the importance of steroidogenesis in regulating reproductive functions, the developmental profile of TSPO expression in the gonads and accessory sex organs has not been completely characterized. As a first step towards understanding the function of TSPO, we studied its expression in male and female murine reproductive organs.

We examined testes and ovaries at embryonic days 14.5 and 18.5, and postnatal days 0, 7, CP690550 14, 21 and 56 of development. In the adult testis, TSPO was expressed in both Leydig

cells and Sertoli cells. In the developing testes TSPO expression was seen in immature Sertoli cells, fetal Leydig cells and gonocytes. In the ovary, TSPO was expressed in the ovarian surface epithelium, interstitial cells granulosa cells and luteal cells. Corpora lutea of ovaries from pregnant mice showed strong expression of TSPO. In the developing ovary, TSPO expression was seen in the squamous pregranulosa cells associated with germ line cysts, together with progressively increasing expression in interstitial cells and the ovarian surface epithelium. In adult mice, the epithelia of other reproductive tissues like the epididymis, prostate, seminal vesicle, oviduct and uterus also showed distinct patterns of TSPO expression. In summary, TSPO expression in Sapitinib both male and female reproductive tissues was not only restricted to steroidogenic cells. Expression in Sertoli cells, ovarian surface epithelium, efferent ductal epithelium, prostatic epithelium, seminal vesiclular epithelium, uterine epithelium and oviductal epithelium suggest either previously unknown sites for de novo steroidogenesis or functions for TSPO distinct from its well-studied role in steroid hormone production.”
