Kinase plays crucial role in polarity control, proliferation of reactive oxygen species which is associated with inflammation.

I repect yor emense contributions in the field of inflamatiom and have a wife suffering from afib which I believe is ROS induced inflammation. Thank you Marc Turner 816 719 5993 KC Mo.
