Abstract
One nonexclusive aspect provides molecules further improved from antibodies that can bind to antigens in an ion concentration-dependent manner. An alternative nonexclusive aspect provides safe and more advantageous Fc region variants that have decreased binding to pre-existing ADA. An alternative nonexclusive aspect provides novel IL-8 antibodies that are superior as pharmaceuticals.
