Key Research Focus Areas
- Anxiolytic Models: Studies explore GABAA receptor modulation and gene expression changes in stress/anxiety paradigms, often comparable to benzodiazepines without sedation/dependence in models.
- Nootropic & Cognitive: Investigated for effects on BDNF expression, memory retention, learning acceleration in low-baseline subjects, and neuroprotection against impairments.
- Neurotransmitter Influence: Impacts serotonin metabolism, enkephalin preservation, monoamine systems, and cytokine balance in neuroimmune research.
- Immunomodulatory: Tuftsin-derived actions on IL-6 and T-helper responses in neuropsychiatric contexts.
