Task: Named Entity Recognition
Input (English):  We hypothesized that inhibition of proteasome function with CI - 1 would block NF - kappaB activation in vivo after intraperitoneal ( i . p . ) treatment with bacterial lipopolysaccharide ( LPS ) , and that NF - kappaB inhibition would be associated with suppression of chemokine gene expression and attenuation of neutrophilic alveolitis .
Output (English): NF - kappaB
