Enterokinase Enhances Influenza A Virus Infection by Activating Trypsinogen in Human Cell Lines
Cleavage and activation of hemagglutinin (HA) by trypsin-like proteases in influenza A virus (IAV) are essential prerequisites for its successful infection and spread. In host cells, some transmembrane serine proteases such as TMPRSS2, TMPRSS4 and HAT, along with plasmin in the bloodstream, have been reported to cleave the HA precursor (HA0) molecule into its active forms, HA1 and HA2. Some try...
متن کاملCharacterization of Nucleoprotein Extracted from Human Influenza A Virus Cultured in Two Different Cell Lines
Background and Aims: Influenza virus nucleoprotein (NP) has the capacity to be used as subunit vaccine, but little is known about the impact of different cultures on its structure. In the present study we aimed to evaluate and compare the Isoelectric focusing (IEF) property of extracted viral nucleoproteins derived from Madin Darby canine kidney (MDCK) cell line and embryonated chicken eggs (EC...

متن کاملFormation of Trypsin from Crystalline Trypsinogen by Means of Enterokinase
Crystalline trypsinogen is most readily and completely transformed into trypsin by means of enterokinase in the range of pH 5.2-6.0 at 5 degrees C. and at a concentration of trypsinogen of not more than 0.1 mg. per ml. The action of enterokinase under these conditions is that of a typical enzyme. The process follows closely the course of a catalytic unimolecular reaction, the rate of formation ...
متن کاملInduction of apoptosis in human tumor cell lines by platelets
Introduction: It has been reported that platelets can eradicate tumor cells in vitro, although the mechanism of this effect has not been determined. The effect of platelets on the induction of apoptosis in tumor cells is largely unknown. Materials and methods: To investigate this effect, two human hematologic cell lines, K562 and Daudi, were independently faced with unstimulated and thromb...
