C1q as a Regulator of Brain Development: Implications for Autism Spectrum Disorders

Cenxiao Fang, Svitlana Garbuzova-Davis, Jun Tan ,Demian Obregon4

Autism spectrum disorders (ASDs) represents a heterogeneous group of neurodevelopmental disorders with similar core features of social and communication impairments, restricted interests and repetitive behaviors. Early synaptic dysfunction due to neuroinflammatory insults may underpin the pathogenesis of abnormal brain development in some of individuals with ASDs. As a critical component of the innate immune response, the complement system comprises both directly acting factors and factors that augment other components of the immune system. Beyond its involvement with innate immune responses in the brain, the complement system also plays important roles in neurodevelopment. Recent studies suggest involvement of complement component C1q in fundamental neurodevelopmental pathways and in maintenance and elimination of dendrites and synapses. The impact of aberrant complement system activity during critical windows of brain development may not only affect the local immune response but lead to atypical brain development. This review summarizes and critically analyzes the evidence of a role for the complement system in the pathogenesis of ASDs.
