Studies have shown that krill-derived peptides can inhibit the activation of inflammatory signaling pathways, such as the NF-κB pathway, which is crucial in regulating the expression of inflammatory mediators. By suppressing the production of pro-inflammatory molecules like TNF-α, IL-1β, and IL-6, Antarctic krill peptides help create a more neuroprotective environment within the brain. This anti-inflammatory action may be particularly beneficial in conditions such as Alzheimer's disease, Parkinson's disease, and multiple sclerosis, where chronic inflammation contributes to neuronal damage and cognitive decline.

Neurotrophic Factor Support and Synaptic Plasticity

Antarctic krill peptides have shown promise in supporting neurotrophic factor production and enhancing synaptic plasticity, two critical aspects of neuroprotection and cognitive function. Neurotrophic factors, such as brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF), play essential roles in neuronal survival, differentiation, and synaptic plasticity. Research has indicated that certain peptide fractions from Antarctic krill can stimulate the expression and release of these crucial neurotrophic factors.

By promoting the production of neurotrophic factors, Antarctic krill peptides may help maintain neuronal health and enhance synaptic plasticity. This mechanism is particularly relevant in the context of age-related cognitive decline and neurodegenerative disorders, where reduced neurotrophic support contributes to neuronal loss and impaired cognitive function. The ability of krill peptides to support neurotrophic factor production offers a potential avenue for preserving cognitive function and promoting neuronal resilience in the face of various neurological challenges.
