MDD is characterized by persistent feelings of sadness, hopelessness, and worthlessness, as well as a loss of interest in activities that were once enjoyable. The etiology of MDD is complex and multifactorial, and the development of animal models is crucial for understanding the underlying mechanisms and developing new therapeutic strategies.The purpose of this study is to establish an animal model of depression induced by the vertical chamber method in adult female crab-eating macaques. The model will enable us to investigate the neurobiological and behavioral mechanisms of depression and test the efficacy of potential antidepressant treatments.MethodsSubjects: Adult female crab-eating macaques (Macaca fascicularis) were selected as the subjects for this study. A total of 16 monkeys were randomly divided into two groups: the experimental group (n=8) and the control group (n=8).Vertical chamber method: The vertical chamber method is a well-established behavioral paradigm used to induce a depressive-like state in animals. In this method, the animals are placed in a transparent cylinder, which is then rotated several times. The animals are then allowed to rest for a period before the process is repeated. This procedure is repeated for a predetermined number of cycles, usually over several days.Behavioral tests: The behavioral tests used in this study include the forced swim test (FST), the open-field test (OFT), and the tail suspension test (TST). The FST and TST are commonly used tests...
