Region specific differential regulation of 5HT-5A and 5B receptor is associated with the difference in stress level between male and female rats

Abstract

Stress-related neuropsychiatric disorders affect nearly all people worldwide irrespective of the age and sex of the person. Females are supposed to experience a higher stress and anxiety as compared to the male individuals. The role of serotonin receptor in stress and anxiety condition is supposed to affect this sex-based difference in stress and anxiety condition between male and female animals. Serotonin receptor system is one of the most important molecular mechanism in brain function involved in a number of vital functions such as apetite, sleep, thermoregulation, aggression, learning, mood, cognition as well as in stress and anxiety. The current preclinical study is analyzing the role of serotonin 5HT-5A and 5B receptor in stress and anxiety in male and female rodents. The study suggests here a differential region specific association of both the serotonin receptor under stressful condition between male and female animals.
