Neuronal and glial cell culture models, often combined with an oxidative stress challenge (such as hydrogen peroxide or glutamate excitotoxicity exposure), are standard systems for studying Cortagen's reported effects on the oxidative-antioxidative balance in neural tissue. Readouts typically include measurement of reactive oxygen species levels, lipid peroxidation markers, and antioxidant enzyme activity (such as superoxide dismutase or glutathione peroxidase) following compound exposure under the oxidative challenge condition.

Lymphocyte culture models, typically using mitogen-stimulated peripheral blood mononuclear cells or isolated T-cell populations, are used to measure interleukin-2 expression by ELISA or qPCR following Cortagen exposure, allowing researchers to quantify the magnitude and time-course of any observed cytokine expression change. This readout is studied in the context of broader autoimmune and immune regulatory signalling research, often alongside other cytokine markers to build a more complete profile of Cortagen's immunomodulatory activity.

Rodent models of cerebral ischemia (such as transient or permanent middle cerebral artery occlusion) and neuroinflammatory challenge paradigms (such as LPS-induced neuroinflammation) are used to study Cortagen's effects in an intact neural tissue context, typically measuring infarct volume, neurological functional scores, and tissue-level inflammatory cytokine or oxidative stress markers as primary endpoints. These in vivo models complement cell-based mechanistic studies by situating Cortagen's pathway-specific effects within a physiologically relevant injury context.
