Abstract:
본 발명은 증가된 반감기를 가지는 삭사틸린 유도체 및 이의 용도에 관한 것이다. 본 발명의 삭사틸린 유도체는 모 단백질인 삭사틸린과 유사한 혈전 용해능을 가질 뿐 아니라 현저하게 증가된 단백질 반감기를 가지고, 이를 이용하여 FeCl 3 -유도된 경동맥 동물 모델에서 혈관 내 이미 형성된 혈전을 장기간 동안 매우 효율적으로 용해시킨다. 따라서, 본 발명의 삭사틸린 유도체를 유효성분으로 포함하는 조성물은 관통 후 재협착도 일으키지 않고, 미세혈관까지 효과적으로 개방시켜 혈관의 협착 또는 폐색 질환(예컨대, 뇌혈관질환, 심혈관질환, 동맥경화성 혈관질환, 관상동맥질환, 말초혈관질환, 등)의 치료에 매우 효과적이다.
Abstract:
The present disclosure provides isolated nucleic acid sequences encoding a monomeric green/yellow fluorescent proteins, and fragments and derivatives thereof. Also provided is a method for engineering the nucleic acid sequence, a vector comprising the nucleic acid sequence, a host cell comprising the vector, and use of the vector in a method for expressing the nucleic acid sequence. The present invention further provides an isolated nucleic acid, or mimetic or complement thereof, that hybridizes under stringent conditions to the nucleic acid sequence. Additionally, the present invention provides a monomeric green/yellow fluorescent protein encoded by the nucleic acid sequence, as well as derivatives, fragments, and homologues thereof. Also provided is an antibody that specifically binds to the green/yellow fluorescent protein.

Abstract:
A method for inhibiting and/or reversing replicative senescence is provided comprising a step of administering a therapeutically effective amount of a compound which mediates allosteric modulation of beta 1 integrin to a subject in need thereof. Typically the allosteric modulation of beta 1 integrin results in beta 1 integrin assuming an intermediate affinity state conformation. The method of the present invention may be used in the treatment and/or prevention of ageing and ageing-related conditions.
Abstract:
The present invention relates to the construction of an assay system for analysing the performance of LRR (leucine rich repeat) proteins, that are constituted by the repeat combination of LRR modules, as septicaemia-inhibiting protein therapeutic agents, and for screening protein therapeutic agents that exhibit an outstanding inhibiting performance from a sequence variation library. More specifically, the present invention relates to: a performance analysis method or screening method for septicaemia protein therapeutic agents, comprising the step of adding purified MD-2 protein to an assay system using a cell line in which an LPS signal transmission receptor is expressed on the surface; a performance analysis method or screening method for septicaemia protein therapeutic agents, comprising the step of adding a purified foreign MD-2 protein to a THP-1 cell line; the cell line for performance analysis or for screening; and a kit for septicaemia therapeutic agent screening or performance analysis, comprising the cell line and purified foreign MD-2.
Abstract:
The present invention relates to novel isolated peptides which induce analgesia and which inhibit ASIC channels (Acid Sensing Ion Channels), to the polynucleotides encoding said peptides, and also to the pharmaceutical compositions, host cells and vectors comprising same. In particular, said peptides are isolated from the venom of the snake Dendroaspis polylepis. The present invention also relates to the use thereof as a diagnostic tool or as medicament, and in particular as an analgesic, or for identifying analgesic molecules or molecules which inhibit ASIC channels.
