Receptors for estrogens and thyroid hormone (T3) have related DNA-binding domains that interact with closely related DNA target sequences which enable transcriptional control. In vitro molecular studies have raised the possibility that estrogen and T3 receptors may compete for binding to certain DNA target sites (cross-talk). However, there have been no(More)
The effects of NGF, BDNF, NT-3, BDNF plus NT-3 and LIF on substance P (SP) mRNA levels were analysed in axotomized dorsal root ganglia (DRGs) in vivo by quantitative in situ hybridization. The growth factors were applied on to the transected sciatic nerve. SP mRNA levels were decreased significantly 3 days after axotomy. NGF (1 microgram) fully counteracted(More)
1. The effect of treating rats with digoxin and thyroxine for 45 days has been studied. 2. Animals fed with digoxin gained significantly more weight than the control animals. 3. Treatment with digoxin, thyroxine or both produced a similar significant increase in the amount of Na+ + K+ -dependent adenosine triphosphatase in liver without an additive effect.(More)
1. The Ca movements in normal and ;ghost' L cells have been examined; all measurements were made using (45)Ca.2. Normal cells have a Ca concentration of about 1 m-mole/l. of cell volume, and exchange Ca in a complex way but with great rapidity; the time taken for the initial Ca(*) content to fall to half was less than 2 min.3. Poisoning normal cells with(More)
Infection and inflammation are known to affect the metabolism and disposition of drugs and carcinogens. We report a detailed study of the effects of bacterial endotoxin on the constitutive and inducible expression and activities of cytochrome P-450 isozymes from families P-450I, P-450IIB, P-450IIC and P-450III. In general high doses of high endotoxin caused(More)
Background We previously showed that plasmacytoid dendritic cells (pDCs) derived from females can produce significantly more IFN-alpha in response to HIV-1 and HIV-1-encoded TLR7/8 ligands than pDCs derived from males, resulting in stronger secondary activation of CD8+ T cells (Meier et al., Nat Med 2009). Given the crucial role of interferon regulatory(More)
