Suppression of Fli-1 protects against pericyte loss and cognitive deficits in Alzheimer's disease

Topic: Amyloid, tau and blood-test diagnosis
Plain-language summary
Brain pericytes regulate cerebral blood flow, maintain the integrity of the blood-brain barrier (BBB), and facilitate the removal of amyloid β (Aβ), which is critical to healthy brain activity. Pericyte loss has been observed in brains from patients with Alzheimer's disease (AD) and animal models. Our previous data demonstrated that friend leukemia virus integration 1 (Fli-1), an erythroblast transformation-specific (ETS) transcription factor, governs pericyte viability in murine sepsis; however, the role of Fli-1 and its impact on pericyte loss in AD remain unknown. Here, we demonstrated that Fli-1 expression was up-regulated in postmortem brains from a cohort of human AD donors and in 5xFAD mice, which corresponded with a decreased pericyte number, elevated inflammatory mediators, and increased Aβ accumulation compared with cognitively normal individuals and wild-type (WT) mice. Antisense oligonucleotide Fli-1 Gapmer administered via intrahippocampal injection decelerated pericyte loss, decreased inflammatory response, ameliorated cognitive deficits, improved BBB dysfunction, and reduced Aβ deposition in 5xFAD mice. Fli-1 Gapmer-mediated inhibition of Fli-1 protected against Aβ accumulation-induced human brain pericyte apoptosis in vitro. Overall, these studies indicate that Fli-1 contributes to pericyte loss, inflammatory response, Aβ deposition, vascular dysfunction, and cognitive decline, and suggest that inhibition of Fli-1 may represent novel therapeutic strategies for AD.

Key findings
- Our previous data demonstrated that friend leukemia virus integration 1 (Fli-1), an erythroblast transformation-specific (ETS) transcription factor, governs pericyte viability in murine sepsis; however, the role of Fli-1 and its impact on pericyte loss in AD remain unknown.
- Here, we demonstrated that Fli-1 expression was up-regulated in postmortem brains from a cohort of human AD donors and in 5xFAD mice, which corresponded with a decreased pericyte number, elevated inflammatory mediators, and increased Aβ accumulation compared with cognitively normal individuals and wild-type (WT) mice.
- Overall, these studies indicate that Fli-1 contributes to pericyte loss, inflammatory response, Aβ deposition, vascular dysfunction, and cognitive decline, and suggest that inhibition of Fli-1 may represent novel therapeutic strategies for AD.

Study details
- Evidence strengthModerate
How this study scored 43/100
Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported, studied in people and randomized / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multicenter collaboration, so those were left out: it earned 25 of the 58 points we could judge it on, which is 43 out of 100.
