摘要:
A pharmaceutical composition, comprising a modified MT-SP1 protease, or a catalytically active part thereof, for use in the treatment of a disease or disorder selected from an inflammatory disorder, a neurodegenerative disorder and a cardiovascular disorder, in the that: the modified MT-SP1 protease, or a catalytically active part thereof, cleaves any one or more target substrates from a complement pathway such that complement activation on a path comprising the target substrate is inhibited; the target substrate is a complement protein; inhibition of complement activation leads to a reduction of inflammatory symptoms associated with the disease or disorder; the modified MT-SP1 protease, or catalytically active part thereof, comprises one or more modifications that increase one or both of specificity for a target substrate and activity towards a target substrate compared to an unmodified MT-SP1 protease; and the modified MT-SP1 protease, or a catalytically active part thereof, comprises one or more modifications selected from I41T, I41A, I41L, I41F, I41D, I41E, Q175H, Q175L, Q175W, Q175Y and Q175K, based on the chymotrypsin numbering.Una composición farmacéutica, que comprende una proteasa MT-SP1 modificada, o una parte catalíticamente activa de la misma, para su uso en el tratamiento de una enfermedad o trastorno seleccionado de entre un trastorno inflamatorio, un trastorno neurodegenerativo y un trastorno cardiovascular, en el que: la proteasa MT-SP1 modificada, o una parte catalíticamente activa de la misma, escinde uno cualquiera o más sustratos diana de una ruta del complemento de tal manera que la activación del complemento en una ruta que comprende el sustrato diana se inhibe; el sustrato diana es una proteína del complemento; la inhibición de la activación del complemento conduce a una reducción de los síntomas inflamatorios asociados con la enfermedad o el trastorno; la proteasa MT-SP1 modificada, o parte catalíticamente activa de la misma, comprende una o
