However, these approaches do not adequately address the core drivers of the disease. This limitation arises from an incomplete understanding of the progression from local injury to systemic inflammation and repair, which is a dynamic process with underlying immunoregulatory mechanisms that remain insufficiently characterized. Macrophages are the key effector cells involved throughout the disease course and exhibit pronounced spatiotemporal heterogeneity during this progression. Therefore, they are central to decoding the evolution of the disease and facilitating precise interventions. In terms of spatial dynamics, tissue\u2010resident macrophages (TRMs), which are derived from embryonic sources, and monocyte\u2010derived macrophages (MDMs) recruited from the bone marrow serve functionally complementary roles. Their relative dominance shifts in conjunction with disease progression rather than remaining static. Temporally, the macrophage phenotype undergoes a programmed evolution, beginning with an early phase dominated by M1 proinflammatory responses, transitioning through an intermediate phase where injury and repair coexist, and culminating in a late phase characterized by M2\u2010dominated reparative coordination. This evolution is accompanied by corresponding metabolic reprogramming. Recent single\u2010cell and spatial multiomics studies have unveiled a functional continuum that goes beyond the traditional M1\/M2 dichotomy, revealing a rich diversity of cellular subsets and their spatial niches. This insight shifts targeting strategies from broad anti\u2010inflammatory interventions toward more precise modulation aimed at specific phases, subsets, and regions. This review systematically examines the design principles, strengths, and limitations of three classes of intervention\u2014molecular targeting, bioactive natural products, and nanoscale delivery\u2014and identifies the obstacles that continue to impede their clinical translation. Building on this analysis, we propose a dual\u2010dimensional (spatiotemporal) strategy of precise modulation, integrating single\u2010cell and spatial omics, chronobiological principles, and the traditional Chinese medical concept of\n                    <jats:italic>yin shi zhi yi<\/jats:italic>\n                    (adapting treatment to timing), with the aim of shifting AP therapy from symptomatic support toward cause\u2010directed repair.\n
