Article Snippet: Numerous studies have shown that exosomes play a regulatory role in a variety of biological processes as well as in disease development and progression.. However, exosome-mediated intercellular communication between brain microvascular endothelial cells (BMECs) and astrocytes during meningitic Escherichia coli (E. coli)–induced neuroinflammation remains largely unknown.. Here, by using in vivo and in vitro models, we demonstrate that exosomes derived from meningitic E. coli–infected BMECs can activate the inflammatory response of astrocytes.

Figure Lengend Snippet: HIF-1α and PKM2 are critical effectors of GDF15-driven mitochondrial protection and anti-inflammatory responses. (A) HIF-1α inhibition by BAY 87-2243 (5 μM, 24 h). β-actin: loading control.(Pharmacological HIF-1α blockade.) (B) PKM2 inhibition by Shikonin (2 μM, 24 h). β-actin: loading control.(PKM2 activity suppression.) (C) UQCRC1 recovery in LPS-injured macrophages treated with: GDF15 overexpression, HIF-1α inhibitor (BAY), or PKM2 inhibitor (Shikonin). β-actin: loading control.(Mitochondrial complex III rescue via HIF-1α/PKM2 inhibition mirrors GDF15 effects.) (D) Inflammatory (TNF-α, IL-6) and metabolic (lactate) markers in cell supernatant (n = 5). Study groups and individual replicates are identified in the figure key. ***p < 0.001.(HIF-1α/PKM2 targeting replicates GDF15-mediated anti-inflammatory and metabolic homeostasis.) (E) UQCRC1 expression under GDF15 loss-of-function: si-GDF15 alone vs. combined with BAY 87–2243 or Shikonin. β-actin: loading control. Study groups and individual replicates are identified in the figure key.(Mitochondrial rescue in GDF15-deficient macrophages requires HIF-1α/PKM2 inhibition.) (F) Supernatant cytokines and lactate in si-GDF15 macrophages with/without inhibitors (n = 5). ***p < 0.001. (Inflammation reversal in GDF15-knockdown macrophages depends on HIF-1α/PKM2 blockade.).

SMAD7 activation suppresses HIF-1α to mediate GDF15-dependent mitochondrial protection in LPS-challenged macrophages. (A) Pharmacological SMAD7 activation by Asiaticoside (20 μM, 48 h). β-actin: loading control. (B) HIF-1α expression under LPS challenge: LPS alone, LPS + AVV-GDF15, or LPS + SMAD7 activation (Asiaticoside). β-actin: loading control. (C) HIF-1α modulation across conditions: LPS, LPS + si-GDF15, LPS + Asiaticoside, or LPS + si-GDF15 + Asiaticoside. β-actin: loading control.
