5-aminoisoquinolinone attenuates social behavior deficits and immune abnormalities in the BTBR T+ Itpr3tf/J mouse model for autism.
Autism spectrum disorder (ASD) is diagnosed by core symptoms including impaired social communication and the presence of repetitive and stereotypical behaviors. There is also evidence for immune dysfunction in individuals with ASD, but it is a disease that is still insufficiently controlled by current treatment strategies. The use of 5-aminoisoquinolinone (5-AIQ) ameliorates several immune-mediated symptoms including rheumatoid arthritis and colitis, and has neuroprotective properties; however, its role in ASD is not yet characterized. ⋯ Additionally, 5-AIQ treatment substantially decreased CXCR4-, CXCR6-, IFN-γ-, IL-22-, NOS2-, STAT1-, T-bet-, and RORγT-producing CD3+ T cells in the spleen. Furthermore, 5-AIQ treatment decreased CXCR4, IFN-γ, IL-22, STAT1, and RORγT mRNA expression levels in brain tissue. Our findings demonstrated that 5-AIQ improved behavioral and immune abnormalities associated with ASD, which supports the hypothesis that 5-AIQ has important therapeutic potential for the treatment of behavioral and neuroimmune dysfunctions in ASD.
