Neurotrophic factors are used for the experimental treatment of neurological disorders, such as Alzheimer's disease. However, delivery of the neurotrophic factors into the brain remains a big challenge. Recombinant human nerve growth factor (NGF)-loaded microspheres were fabricated and characterized in vitro and in vivo in our previous study. The present study was to assess the therapeutic benefit of rhNGF-loaded microspheres in treating the rat model of Alzheimer's disease with fimbria-fornix lesion. Recombinant human NGF-loaded microspheres were implanted into the basal forebrain of the rats with fimbria-fornix lesion. Four weeks after implantation in the basal forebrain, immunohistochemical analysis showed that rhNGF-loaded microspheres had a significant effect on the survival of axotomized cholinergic neurons in the medial septum (MS) and vertical diagonal branch (VDB) (p<0.05). Y-maze tests showed rhNGF-loaded microspheres can significantly improve the ability of spatial learning and memory of the rats with fimbria-fornix lesion (p<0.05). These results indicate that rhNGF-loaded microspheres are an effective means for the treatment of Alzheimer's disease.

Leukemia inhibitory factor (LIF) inhibits basal bone resorption in fetal rat long bone cultures

Q3 · MEDICINE

Article

Author: Joseph A. Lorenzo ; Christina L. Leahy ; Sandra L. Sousa

Leukemia inhibitory factor (LIF) has a wide variety of biologic actions. In vivo, its net effect on bone is to increase new bone formation. Recently, the sequence of human LIF was found to differ by only a single amino acid from that of human differentiation-inducing factor (D-factor). The effects of LIF on bone appear to be complex since purified murine D-factor and recombinant LIF stimulate bone resorption in cultured newborn mouse calvaria. To examine further the responses of bone to LIF, we studied the effects of recombinant human LIF (glycosylated and nonglycosylated) and recombinant human D-factor (non-glycosylated) on resorption in another in vitro organ culture model, fetal rat long bones. Both LIF preparations and D-factor inhibited basal bone resorption rates by 25% to 44% in these cultures. Resorption rates in maximally inhibited LIF-treated cultures were similar to those in devitalized bones. Inhibitory effects typically occurred at concentrations of greater than or equal to 10 ng/mL (0.5 nM) for the non-glycosylated LIF and D-factor and 1000 U/mL for glycosylated LIF. Neither LIF nor D-factor blocked the resorptive response to interleukin 1 (IL 1) or parathyroid hormone (PTH) nor did they alter total DNA synthesis. Hence, their inhibitory effects appeared to be specific for the mechanisms regulating basal resorptive activity. These results demonstrate that LIF has potent inhibitory actions on basal resorption rates in these cultures. These effects may be important for the anabolic responses that LIF has on bone in vivo. In addition, they may also be involved in the interactions between inflammatory or tumor cells and bone.
