Fig 2. IL-1β induced a decrease in TER values.

In cells treated with 10% FBS (open circles) and 2% FBS in the presence (closed circles) or absence (closed squares) of IL-1β (50 pM) for the indicated time periods, the barrier properties were monitored by measuring TER. Results are presented as mean ± SE from three independent experiments. *P < 0.05 vs. cells treated with 10% FBS (open circles). †P < 0.05 vs. cells treated with 2% FBS in the absence of IL-1β (closed squares).
