Laboratory research of cough reflex utilizes almost exclusively
male guinea pigs – a practice that represents a significant obstacle
in the successful translation of results into clinical practice. Chronic
hypersensitivity cough syndrome affects mostly postmenopausal
women and it represents significant decrease in patient’s quality
of life. No cause for such exaggerated cough can be found,
therefore this condition cannot be treated appropriately. One of
the reasons leading to the lack of relevant data about mechanisms
responsible for hypersensitivity of cough related pathways is
nowadays widely discussed gender bias, which is present in nearly
all branches of biomedical research. Since gender differences in
cough reflex physiology do exist in humans, it would be reasonable
to study cough-related phenomena on both sexes of laboratory
animals. In this study, we focused on detailed characterization of
cough response of female guinea pigs to aerosols of commonly
used tussive agents (capsaicin, distilled water, allyl isothiocyanate,
cinnamaldehyde, citric acid). In pooled data from multiple
challenges we found no statistical difference in number of cough
and cough latency between sexes. Based on our results we
conclude that the utilization of female guinea pigs model does not
lead to messy data and can be used in basic cough research.
