Interestingly, using Aβ42 mice, the results showed that the level of IL-17 was increased in Aβ42 model mice, and IL-17Ab could ameliorate Aβ-induced neurotoxicity and cognitive decline in 10 C57BL/6 mice by downregulating the TRAF6/NF-κB pathway. The gene discussed is TRAF6; the disease is Mental deterioration.
