Sexual dimorphism of
chemoreflexes and respiratory control in general has been acknowledged for
years; however, owing to its apparent complexity, this aspect has been
virtually dismissed or ignored. The recent interest in respiratory
plasticity and the underlying mechanisms has brought many researchers to
investigate how steroid hormones and various environmental conditions (e.g.
stress) can have immediate and long lasting consequences on the way this
vital homeostatic system develops and operates throughout life. The outcome
of this research has revealed the immense impact that neuroendocrine factors
can exert on the respiratory control system, and have opened new and
promising research avenues as the fields of neuroendocrinology and
respiratory control have begun to interact to address the question: “what
role do hormones play in the function and programming of the respiratory
control system”?
To favour discussions between
researchers, we propose to bring together speakers that will address this
question from a variety of angles ranging from sexual dimorphism on the
impact of neural erythropoietin on the hypoxic ventilatory response (Dr
Gassman, Switzerland) to the effects of testosterone on respiratory control
during sleep in human subjects (Dr. Mateika, USA). These speakers were
selected for their ability to approach this question with different
approaches including neuroanatomy and electrophysiology in animal models
(Drs Kinkead, Canada), in vivo study of peripheral chemoreceptor function in
newborn mammals (Dr. Joseph, Canada), to pharmaceutical tools in human
subjects (Dr. Mateika, USA) and genetic engineering in mice (Dr. Gassman).
In addition to presenting their most recent results, each speaker will put
their work in a broader perspective to favour interactions between
disciplines and help generate new ideas. This session should be of interest
to both clinicians and basic scientists, and given the multidisciplinary
nature of this topic we anticipate that, in addition to the respiratory
section, this symposium will be of interest to members of other APS sections
such as cardiovascular, central nervous system, neural control and autonomic
regulation, endocrinology and metabolism.
