               CONCLUSION
               Hormonal and genetic environments determine microglia fate to be sex-specific. There are several sex
               differences in microglia physiology, distribution throughout the brain, functional responses, transcriptional
               profiles, and sex chromosome composition. Some of these are maintained throughout the lifespan of the
               individual; however, most of them are dynamic and vary over time. As microglia play a key role in every
               neurological disease, it is likely that the differences they present contribute to sex differences in the course
               and incidence of these disorders. Therefore, sex differences in microglia are a new and promising research
               field to explain the differences in neurological disorders in humans and potentially lead to sex-specific
               strategies to treat these patients.
