    Ischemic stroke is a cerebrovascular disease affecting the blood vessels and blood supply to the brain, which has become the second leading cause of death throughout the world. Studies suggested that immune cells play a dual role during the stroke inflammation and recovery phase, but their in-depth investigations of specific cell subtypes along with their differentiation trajectories are yet to be disentangled. In this review, we highlight the application of single-cell RNA sequencing (scRNA-seq) on unbiased identification of cell heterogeneity in brain and peripheral blood mononuclear cells (PBMCs) during and after stroke, aiming to unravel the phenotypic landscape of cells with different roles in stroke. Specifically, we provide an overview of roles, cell surface markers, immune cell-released cytokines and intercellular interactions found by different technologies in major immune cells during and after stroke, and summarised the connection of immune cells between peripheral blood and brain via differentiation trajectories. Through the above reviews, we synthesise the application of scRNA-seq on the combination of PBMCs and brain tissue at higher sampling frequency to unveil the dual role of peripheral immune cells, which could aid the development of new treatment strategies of ischemic stroke.p
