Problems solved by technology

However, even though clinical-grade hESC lines are readily available, transplanting neurons derived from in vitro differentiated HESCs is risky and requires highly invasive intracerebral injections to deliver neurons into the patient's brain

Embodiment 1

[0034] Example 1 Granulocyte colony-stimulating factor ameliorates learning deficit in a mouse model of Alzheimer's disease

[0035] Alzheimer's-like progressive neurodegeneration was induced in mice by intraventricular injection of aggregated Aβ-type peptides (as previously described by Yan et al.)

[0036] Aggregated Aβ-type peptides were prepared from 10 mM soluble Aβ (1-42) Prepare in solution in 0.01 M phosphate buffer, pH 7.4. Aβ-type peptides were purchased from Sigma-Aldrich (St. Louis, MO). Aβ solutions were heated at 37°C for three days to form aggregated Aβ-type peptides and stored at -70°C before use. Eight-week-old C57BL / 6 male mice were anesthetized with intraperitoneal sodium pentobarbital (40 mg / kg) before injection of aggregated Aβ-type peptides. The aggregated A[beta]-type peptides were then injected stereotaxically into the dorsal hippocampus and both sides of the cerebral cortex using a 26-gauge needle attached to a Hamilton microregulation syringe (Ha...

[0044] Long-lasting effects of granulocyte colony-stimulating factor

[0045] In order to test whether granulocyte colony-stimulating factor (G-CSF) can have a long-term therapeutic effect, the cognitive ability of Tg2576 mice was analyzed 3 months after treatment. To this end, 10 12-month-old mice were divided into two groups and tested with a water maze task as described above before and 3 months after subcutaneous injection of PBS and granulocyte colony-stimulating factor (G-CSF), respectively. like figure 1 As shown, the average latency of Tg2576 mice treated with PBS (3 months after Tg2576 injected with PBS) and not treated with PBS (Tg2576 administered with PBS injected control) was generally high. Clearly, however, granulocyte colony-stimulating factor-treated mice had significantly better learning / memory abilities, even 3 months after treatment (Tg2576 injected with G-CSF 3 months later vs Tg2576 administered with G-CSF injection control comparison). These data demo...

Abstract

The invention provides a drug combination for treating progressive nerve degradation or inhabiting the happening of the progressive nerve degradation of a high risk curer. The drug combination at least comprises the agent of a granulocyte colony stimulating factor receptor in effective quantity, thereby moving hematopoietic stem cells to peripheral blood from bone marrow. The combination can also be used for inhibiting the happening of the progressive nerve degradation on the high risk curer. In addition, a choice of the methods is provided for treating the agent of the granulocyte colony stimulating factor receptor of the progressive nerve degradation.

Description

technical field [0001] The present invention relates to a pharmaceutical composition of a granulocyte colony-stimulating factor receptor agent and its use in the manufacture of medicines. Background technique [0002] Progressive neurodegenerative disorders (PNDs), such as Alzheimer's disease, cause slow but invariable neuronal loss accompanied by a reduction in cognitive or motor function, with the result being the death of the subject. Progressive neurodegeneration has a devastating impact on the quality of life of those affected and their families. In addition, progressive neurodegeneration imposes a heavy health care burden on society. In fact, such diseases mainly affect the expanding elderly population, so their prevalence and social impact are expected to increase in the coming years. [0003] One of the most promising treatments for progressive neurodegeneration is neuron replacement with transplanted neurons derived from stem cells, which in very small numbers are...
