Immune Tuning in Extreme Environments: Protein Citrullinome and Extracellular Vesicle Signatures Comparing Hibernating Versus Active States in the Heterothermic and Heterometabolic Tenrec (<i>Tenrec ecaudatus</i>).

ABSTRACT: Tenrecs are heterothermic burrowing mammals, which are capable of withstanding extreme environmental stressors, including during hibernation. Their phylogenetic position as reminiscent of an ancestral placental mammal makes tenrecs a unique model for evolutionarily conserved traits, with potential translatability to human physiology and pathobiology, including adaptations to extreme environments. In this study, we compared tenrec plasma for post-translational protein citrullination profiles (citrullinomes) and extracellular vesicle (EV) characteristics, including selected microRNA cargoes (miR-21, miR-155, miR-206, miR-210), between baseline active and hibernating states at low (12 °C) and high (28 °C) ambient temperatures. Our findings show considerable changes in citrullinome plasma prof
