The KE peptide, being a fragment of the cytokines IL-lα, IL-2, IL-4, IL-5, IL-6, and INF-α, stimulates the synthesis of mRNA of the cytokine IL-2 in lymphoid cells [53] Consequently, it is suggested that the AEDG and KE peptides may have a neuroprotective effect through the regulation of neuroinflammation in AD. The gene discussed is IL5; the disease is Alzheimer disease.
