The costs of coping: Different strategies to deal with social defeat stress might come with distinct immunologic, neuroplastic, and oxidative stress consequences in male Wistar rats.

The impact of stress on health and well-being is determined by the ability of an individual to cope with challenges imposed by the stressor. Animals exposed to social defeat stress show different patterns of response during confrontations, leading to distinct stress-induced consequences. Using an established resident-intruder paradigm, we explored the outcomes of adopting active or passive coping strategies during a social defeat protocol over peripheral and central nervous system (CNS) levels of inflammatory cytokines, growth factors, glucocorticoid, and oxidative stress markers in male Wistar rats.
