Abstract
INTRODUCTION Depression is a highly debilitating psychiatric disorder that affects the global population and causes severe disabilities and suicide. Depression pathogenesis remains poorly understood, and the disorder is often treatment-resistant and recurrent, necessitating the development of novel therapies, models and concepts in this field. Areas covered: Animal models are indispensable for translational biological psychiatry, and markedly advance the study of depression. Novel approaches continuously emerge that may help untangle the disorder heterogeneity and unclear categories of disease classification systems. Some of these approaches include widening the spectrum of model species used for translational research, using a broader range of test paradigms, exploring new pathogenic pathways and biomarkers, and focusing more closely on processes beyond neural cells (e.g. glial, inflammatory and metabolic deficits). Expert opinion: Dividing the core symptoms into easily translatable, evolutionarily conserved phenotypes is an effective way to reevaluate current depression modeling. Conceptually novel approaches based on the endophenotype paradigm, cross-species trait genetics and 'domain interplay concept', as well as using a wider spectrum of model organisms and target systems will enhance experimental modeling of depression and antidepressant drug discovery.

High-fructose diet during adolescent development increases neuroinflammation and depressive-like behavior without exacerbating outcomes after stroke. Brain Behav Immun 2018; 73:340-351.

Abstract
Diseases, disorders, and insults of aging are frequently studied in otherwise healthy animal models despite rampant co-morbidities and exposures among the human population. Stressor exposures can increase neuroinflammation and augment the inflammatory response following a challenge. The impact of dietary exposure on baseline neural function and behavior has gained attention; in particular, a diet high in fructose can increase activation of the hypothalamic-pituitary-adrenal axis and alter behavior. The current study considers the implications of a diet high in fructose for neuroinflammation and outcomes following the cerebrovascular challenge of stroke. Ischemic injury may come as a "second hit" to pre-existing metabolic pathology, exacerbating inflammatory and behavioral sequelae. This study assesses the neuroinflammatory consequences of a peri-adolescent high-fructose diet model and assesses the impact of diet-induced metabolic dysfunction on behavioral and neuropathological outcomes after middle cerebral artery occlusion. We demonstrate that consumption of a high-fructose diet initiated during adolescent development increases brain complement expression, elevates plasma TNFα and serum corticosterone, and promotes depressive-like behavior. Despite these adverse effects of diet exposure, peri-adolescent fructose consumption did not exacerbate neurological behaviors or lesion volume after middle cerebral artery occlusion.
