Immune system deregulation has been demonstrated to occur during and immediately following spaceflight. Several animal models have been used to study this phenomenon because of the limited availability of human subjects in space as well as of the need to carry out experiments requiring samples and experimental conditions that cannot be performed using humans. Here, we review major spaceflight-induced microbial and immunological modifications, some of the existing hardware developed to host amphibians in a space station and immunological information provided by space experiments performed with Pleurodeles waltl as an animal model. These data show that the urodele amphibian P. waltl fulfills many technical requirements associated with spaceflight experimentation and that this model is interesting to improve our understanding of the immunosuppressive effects of spaceflight, data required for the preparation of future deep-space missions.

UI MeSH Term Description Entries
D007107 Immune System The body's defense mechanism against foreign organisms or substances and deviant native cells. It includes the humoral immune response and the cell-mediated response and consists of a complex of interrelated cellular, molecular, and genetic components. Immune Systems,System, Immune,Systems, Immune
D009024 Morphogenesis The development of anatomical structures to create the form of a single- or multi-cell organism. Morphogenesis provides form changes of a part, parts, or the whole organism.
D010999 Pleurodeles A genus of aquatic newts belonging to the family Salamandridae and sometimes referred to as "spiny" tritons. There are two species P. waltlii and P. poireti. P. waltlii is commonly used in the laboratory. Since this genus adapts to aquarium living, it is easy to maintain in laboratories. Pleurodele

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D014893 Weightlessness Condition in which no acceleration, whether due to gravity or any other force, can be detected by an observer within a system. It also means the absence of weight or the absence of the force of gravity acting on a body. Microgravity, gravitational force between 0 and 10 -6 g, is included here.
