The invention relates to application of a ventral
hippocampal region transferrin receptor 1 inhibitor in preparation of a
medicine for preventing and / or treating
anxiety disorder, and belongs to the technical field of biological
medicine. The application of the inhibitor for interfering with the
animal brain ventral
hippocampal region transferrin receptor 1 (TfR1) in the drugs for preventing and / or treating
anxiety is discovered and proposed for the first time. Animal experiments prove that
anxiety disorder caused by social isolation stress is closely related to TfR1 in a brain abdominal side
hippocampus area of an animal, and when the animal shows anxiety symptom, the expression level of TfR1 is improved, so that the iron concentration in the brain abdominal side
hippocampus area is improved to cause iron disorder. On the basis of the research, an inhibitor for interfering with the TfR1 in the belly
hippocampus area of the brain of the animal is injected into an anxiety model animal, social isolation treatment is continued, the anxiety behavior of the animal in a social isolation treatment group is improved, and the effect of treating the anxiety is achieved.
