Primary Research Interests: Our laboratory studies pain transmission with a special emphasis on the influence of gender and immunology. The goal is to understand painful conditions, such as fibromyalgia syndrome, that occur more frequently in females and are exacerbated by stress. Our focus is on stress hormones and on mast cells, immune cells that enter the CNS in response to stress and certain reproductive hormones.
Mast cells are localized in the thalamus, an area important in sensory transmission, including pain. Mast cells are more abundant in specific areas of the female than the male thalamus. Interfering with the degranulation of mast cells by the central injection of cromolyn, a mast cell stabilizer, blocks the acquisition of appropriate breeding behaviors in female mice, perhaps by an influence on sensory transmission. Chronic stress increases the number of mast cells in the thalamus, suggesting that they become increasingly important in these circumstances.
