Why the study?

The effects of S100A8/A9 blockade on myocardial inflammation and post-ischemic myocardial injury required investigation in a mouse model of coronary artery ligation.

Does S100A8/A9 blockade with ABR-238901 reduce neutrophil infiltration and myocardial infarction size in a mouse model of coronary artery ligation?

Population

Mouse model of coronary artery ligation

Comparison

3-day treatment with the S100A8/A9 blocker ABR-238901 vs control

Design

Preclinical animal study

Follow-up

3 days post-MI

Key result

A 3-day treatment with the S100A8/A9 blocker ABR-238901 significantly decreased neutrophil infiltration and reduced infarction size in a mouse model of myocardial infarction.

Overview

Short-term S100A8/A9 blockade reduced infarct size and neutrophils in mice; leaves open immunomodulatory potential pending human translation.

Structured PICO

Does S100A8/A9 blockade with ABR-238901 reduce neutrophil infiltration and myocardial infarction size in a mouse model of coronary artery ligation?

P
Population
Wild-type female mice aged 8-12 weeks subjected to permanent left anterior descending coronary artery ligation to induce myocardial infarction.
I
Intervention
ABR-238901 (S100A8/A9 blocker) 30 mg/kg intraperitoneal injection administered immediately after MI and repeated after 24 and 48 hours (3-day treatment).
C
Comparator
Phosphate-buffered saline (PBS) intraperitoneal injections administered at the same time points, and sham-operated mice.
O
Outcome
Neutrophil infiltration (Ly6G staining), S100A9 presence, and infarction size (percentage of left ventricular volume) at 1 and 3 days post-MI.surrogate

Short-term blockade of S100A8/A9 with ABR-238901 reduces acute neutrophil infiltration and infarct size in a mouse model of myocardial infarction, highlighting its potential as a therapeutic target to modulate post-ischemic inflammation.

Limitations

  • Animal model study, which may not fully translate to human clinical outcomes
  • Short-term follow-up limited to 3 days post-myocardial infarction

Cite This Study

Mareş et al. (2023) studied Myocardial infarction. ABR-238901 vs. Phosphate-buffered saline (PBS) was evaluated on Myocardial infarction size and neutrophil infiltration. A 3-day treatment with the S100A8/A9 blocker ABR-238901 significantly decreased neutrophil infiltration and reduced infarction size in a mouse model of myocardial infarction.
