Abstract:
본 발명은 hBM-MSC과 미노사이클린을 병용투여에 관한 것으로서, 종래에 미노사이클린 단독 사용시 다발성경화증의 임상적 심각도를 개선하고, 항염증, 신경보호 효과 및 장기사용에 좋은 내성을 보이는 반면 CNS에 독성이 있었던 문제점을 개선한 것이다. 미노사이클린 또는 hBM-MSC를 개별적으로 사용한 경우에 비해서 병용투여한 경우 면역점수(clinical score)에서 현저한 감소를 나타냈다. 더욱이 hBM-MSC과 미노사이클린의 병용투여는 면역조절효과를 강화하며, 전염증 사이토카인(IFN-γ, TNF-α)를 억제하고, 역으로 항염증 사이토카인(IL-4, IL-10)을 증가시킨다. 또한 TUNEL 염색을 통해 개별투여에 비하여 병용투여한 경우 사멸세포의 수가 현저하게 감소한 것을 확인하였다. 따라서, hBM-MSC과 미노사이클린의 병용투여를 다발성경화증의 치료에 유용하게 사용할 수 있다.
Abstract:
The present invention relates to a combined usage of valproic acid (VPA) for overcoming the resistance of cancer cells to temozolomide (TMZ), especially for O6-methylguanine-DNA methyltransferase (MGMT) expression reduction and temozolomide tolerance overcoming functions in neuroglioma cells.
Abstract:
The present invention relates to a composition containing IFNβ-hBM mesenchymal stem cells (MSCs) to which IFN-β gene is introduced as an active ingredient for preventing or treating multiple sclerosis or encephalomyelitis; and to a method for producing the same. More specifically, the IFNβ-hBM-MSCs of the present invention have immunomodulatory functions of reducing Th1 cytokine in blood plasma and increasing Th2 cytokine in blood plasma; prevent demyelination of nerve cells; have a neuroprotective effect; and inhibit inflammatory infiltration or inhibit permeability of a blood brain barrier (BBB). Therefore, the composition can be used for preventing and treating multiple sclerosis and encephalomyelitis.
Abstract:
The present invention relates to an administration of both human bone marrow mesenchymal stem cells (hBM-MSCs) and Minocycline. The Minocycline improves a clinical magnitude of multiple sclerosis, exhibits good effects for anti-inflammation, nerve protection, and long-term use, yet has toxicity in CNS. The hBM-MSCs have shown immunity adjusting functions and nerve protecting functions. Compared to when Minocycline or hBM-MSCs are individually used, a remarkable decrease is exhibited in a clinical score when both Minocycline and hBM-MSCs are administrated. Moreover, when both Minocycline and hBM-MSCs are administrated, immunity adjusting effects are reinforced, and inflammatory cytokines (IFN-γ, TNF-α) are controlled. In contrast, anti-inflammatory cytokines (IL-4, IL-10) are increased. Furthermore, when both Minocycline and hBM-MSCs are administrated, the number of dead cells is remarkably decreased through TUNEL coloring compared to individual administration. When both Minocycline and hBM-MSCs are administrated, provided is a protocol of a new technique for treating multiple sclerosis.
Abstract:
본 발명은 테모졸로미드(temozolomide, TMZ)에 저항성을 가지는 암세포에 대하여, 이를 극복할 수 있는 발프로산(valproic acid, VPA)의 병용 사용에 대한 것으로, 특히, 신경교종 세포에서 상기 발프로산의 MGMT(O6-methylguanine-DNA methyltransferase) 발현 감소 및 테모졸로미드 내성 극복기능에 관한 것이다.
Abstract:
The present invention relates to a suicide-gene cancer therapy by combining valproic acid (VPA) with stem cells expressing suicide genes such as herpes simplex virus type I thymidine kinase (HSV-TK). Glioma cells and the suicide gene-expressing stem cells treated with the valproic acid are cultured in combination with each other, thereby up-regulating the gap junction and enhancing the bystander effect, leading to an increase in the anticancer effect.
