The present invention belongs to the field of pharmacy and cell biology, and relates to an efficient and reliable high content CCR4 antagonist screening cell model using human chemokine receptor 4 as a target, and a screening method thereof. According to the present invention, a cell line being subjected to human CCR4-enhanced green fluorescent protein fusion expression introducing is established, excitation is performed through human thymus activation regulated chemokine and human macrophage chemotatic factor, the CCR4 with green fluorescent protein is induced to produce re-distribution so as to form green fluorescent particles, and the CCR4 antagonist screening cell model for high-content screening is established; the bioactivity of the compound is evaluated by determining the CCR4 green fluorescent particle formation excited or inhibited by the screened compound through the model; and the established drug screening model is the sensitive, efficient and reliable CCR4 antagonist screening cell model suitable for high-throughput and high-content screening, and the method is the sensitive, efficient and reliable method suitable for high-throughput and high-content screening.
