METHODS : This study included 101 hospitalized patients under 2 years who suffered from RSV pneumonia and 108 hospitalized patients under 2 years who suffered only from pneumonia without RSV infection.
However , during RSV infection , IkappaBalpha has only a partial inhibitory effect on NF-kappaB activation.
The 2.3 A crystal structure of IkappaBalpha in complex with the NF-kappaB p50/p65 heterodimer reveals mechanisms of these inhibitory activities.
ASK1/p38 silences the Fas promoter by inhibition of IkappaBalpha phosphorylation - thereby limiting NF-kappaB activity.
