Our research indicates that ACE is vital for myeloid cell functions. Using ACE10\/10 recombinant mice, we demonstrated that overexpressing ACE in macrophages mitigates AD pathology in these mice. Given that neutrophils are the most abundant white blood cells, this study investigates whether ACE overexpression in neutrophils influences AD progression. We crossed NeuACE mice, which overexpress ACE in neutrophils, with 3xTg-AD mice to create AD-NeuACE mice. Behavioral changes and brain pathology were assessed through various behavioral mazes and histological assays. AD-NeuACE mice demonstrated improved cognitive functions and lower A\u03b2 levels in the cortex and hippocampus compared to AD mice.\n                    <jats:italic>In-vitro<\/jats:italic>\n                    data indicate that ACE-overexpressing neutrophils are significantly more effective at phagocytosing and clearing A\u03b2 fluorescence particles. This study suggests that overexpressing ACE in neutrophils could be a promising approach to managing AD-like phenotypes.\n
