In the kallikrein/kinin system, the ASP induce the production of kinin from kininogen (low MW or high MW). The kinin also release caused edema at the infection site and shock in the circulation. The schematic representation of this action is represented : [http://www.degruyter.com/viewimg/j/bchm.2017.398.issue-10/hsz-2016-0344/hsz-2016-0344.xml?img=graphic/j_hsz-2016-0344_fig_002.jpg '''acting points of ASP in the kinin system''' ] | |||
Experiments have been done in order to try to reduce the virulence activity of ASP. It has been demonstrated that the [http://fr.wikipedia.org/wiki/Alpha-2_macroglobuline α2-macroglobulin], a plasma protein, can limit ASP activity. This protein can bind to ASP which is also inactivated. <ref>Inhibition of Aeromonas sobria serine protease (ASP) by α2-macroglobulin. Murakami Y et al.
