Fig. 3From: A systemic immune challenge to model hospital-acquired infections independently regulates immune responses after pediatric traumatic brain injuryImmune cell populations in circulating blood at 24 h post-LPS (i.e., 5 days post-surgery) and 4 days post-LPS (i.e., 8 days post-surgery). Representative scatter plots from flow cytometry demonstrate use of cell-specific markers to identify cell populations in blood at 24 h post-LPS (a–c) and 4 days post-LPS (d–f)Back to article page
