Also demonstrates the differential effects of DHT on bone cell activities in estrogen sufficient and estrogen deficient rats suggesting that there is an interaction of estrogens and androgens on bone cell metabolism in the female rat. / Thesis (Ph.D.)--University of Adelaide, Dept. of Physiology, 1998?

Neural stem cell (NSC) transplantation induces recovery in animal models of central nervous system (CNS) diseases, in part by modulating adaptive and innate immune responses. Since metabolism governs the phenotype and function of immune cells, the aim of this thesis was to investigate whether NSCs have the ability to regulate the immunometabolic components underpinning neuroinflammation. Herein I have identified a new mechanism by which transplanted somatic and directly-induced NSCs counteract CNS-compartmentalised chronic inflammation in mice. NSC transplantation reduces the immunometabolite succinate in the cerebrospinal fluid, while decreasing the burden of mononuclear phagocyte (MP) infiltration and secondary CNS damage. Mechanistically, the anti-inflammatory activity of NSCs arises in response to succinate released by inflammatory MPs, which activates succinate receptor 1 (SUCNR1)/GPR91 on NSCs, thus initiating prostaglandin E2 secretion and extracellular succinate scavenging. This work uncovers a succinate-SUCNR1 axis in NSCs that clarifies how stem cells respond to inflammatory metabolic signals to inhibit the activation of pro-inflammatory MPs in the chronically inflamed brain.

Splice variants of the transient receptor potential vanilloid type-1 (TRPV1) channel appear to be involved in the physiological detection of extracellular fluid (ECF) osmolality in the supraoptic nucleus (SON) and organum vasculosum lamina terminalis (OVLT). It remains to be determined whether these splice variants are directly involved as pore-forming proteins in the osmosensory transduction complex. Since these TRPV1 splice variants are not sensitive to capsaicin antagonists, such as capsazepine (Sharif Naeini et al., 2007), novel tools that specifically interfere with ion permeation through TRPV1 are required for functional studies on the involvement of this channel. In this study, we developed rabbit polyclonal antibodies targeting specifically the extracellular pre-pore loop region of rat TRPV1 (PH-4281). Histological results showed that PH-4281 is specific to rat TRPV1 and TRPV1 expression is found in regions that are known to be osmosensitive. PH-4281 could be used as a specific tool to study the osmosensory transduction complex.

Mesenchymal stromal cells (MSC) are bone marrow-derived, non-hematopoietic progenitors that are amenable to genetic engineering, making them attractive delivery vehicles for therapeutic proteins. However, limited transplanted cell survival compromises the efficacy of MSC-based gene therapy. We hypothesized that co-implantation of insulin-like growth factor-1 (IGF-I)-overexpressing MSC (MSC-IGF) would improve MSC-based therapy of anemia by providing paracrine support to erythropoietin (EPO)-secreting MSC (MSC-EPO). Murine MSC were found to express the IGF-I receptor and be responsive to IGF-I stimulation. IGF-I also improved MSC survival in vitro. MSC were admixed in a bovine collagen matrix and implanted by subcutaneous injection in a murine model of chronic renal failure. Mice receiving MSC-EPO co-implanted with MSC-IGF experienced a greater and significantly sustained elevation in hematocrit compared to controls; heart function was also improved. Co-implantation of MSC-IGF therefore represents a promising new strategy for enhancing implanted cell survival, and improving cell-based gene therapy of renal anemia.
