THP-1 cells were, therefore, stimulated with 1 μg/ml LPS, a concentration mimicking an infection from Gram-negative bacteria, in the presence or absence of 100 μg/ml bLf, and production of IL-6 and IL-1β as well as expression of Fpn, TfR1, Ftn, and Cp-GPI was assessed. The gene discussed is TFRC; the disease is infection.
