Abstract

In rabbits, the fasting-dependent reduction of LH secretion is likely mediated by leptin and estrogens via receptors in the brain. For the first time, using immunohistochemistry, the presence and regulation of receptors for leptin (Ob-R) and estradiol-17beta subtype alpha (ERalpha) were studied in the subcommissural organ (SCO) of rabbits, which were fed either ad libitum (control) or fasted for 48 h (treated) to verify whether this brain structure is a potential site of integration for metabolism and reproduction. In control rabbits, the cytoplasm of glial cells lining the SCO evidenced strong Ob-R immunoreactivity, whereas both ependymal and hypendymal cells of this glandular-like structure were negative. The Ob-R positive glial cells were identified as fibrous astrocytes using the phosphotungstic acid-hematoxylin histochemical (PTAH) and glial fibrillary acidic protein (GFAP) immunohistochemical techniques. ERalpha immunoreactive nuclei were detectable exclusively in the specialized cells forming the SCO, whereas surrounding astrocytes and neurons were negative. Compared to controls, in fasted rabbits, the staining of Ob-R immunoreaction was reduced in the cytoplasm of positive astrocytes, but greatly enhanced in plasma membranes, whereas the number of ERalpha immunoreactive SCO cells was increased (13.2+/-2.7 vs. 5.2+/-2.0, P

Abstract

Inflammation of the uterus and oviduct is associated with reduced reproductive performance in humans and domestic animals. Toll-like receptors are expressed in various immune and non-immune cells and play a crucial role in innate immunity. Toll-like receptor - 4 (TLR4) can detect lipopolysaccharide (LPS) from Gram-negative bacteria leading to the secretion of pro-inflammatory cytokines, chemokines, antimicrobial peptides and other inflammatory mediators. To investigate the effects of a local inflammation on the expression levels of TLR4 and pro-inflammatory cytokines, 12 female rabbits received an intracervical infusion with either saline solution endotoxin-free (carrier, 2 mL; n = 6) or LPS (500 μg diluted in 2 mL of saline solution; n = 6). Blood samples were performed at 0, 30, 60 and 90 min and 2,4,6 and 24 h after treatment to evaluate interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) plasma concentrations. Animals were sacrificed 24 h post-treatment. The uterus and oviducts were immediately collected. The gene expression and protein levels of TLR4 and pro-inflammatory cytokines were detected by quantitative real-time PCR (qRT-PCR) and immuno-histochemical assay, respectively. Our study showed that the intracervical administration of LPS induced local inflammation given that the animals showed no clinical signs, the histological samples revealed signs of inflammation and plasma levels of pro-inflammatory cytokines were unchanged compared to the control. LPS produced an increase in the TLR4 mRNA expression levels in the uterus with respect to the control (P
