“…Currently, many disparate mechanisms, such as decline in neurogenesis, an imbalance in excitatory/inhibitory neurotransmission, and dysregulated immune response, have been hypothesized to be involved in the onset and development of ASD-related behavior ( Selimbeyoglu et al, 2017 ; Cai et al, 2018 ; Cristiano et al, 2018 ; Cai et al, 2019 ; Zhang et al, 2019 ; Dong et al, 2020 ; Poornimai Abirami et al, 2020 ; Sacai et al, 2020 ; Adhya et al, 2021 ; Zhong et al, 2020 ; Baranova et al, 2021 ; Cast et al, 2021 ). Notably, the emerging microbial knowledge has pointed that the complex intestinal microbial community and their metabolic consequences may contribute to ASD etiopathogenesis of core symptoms, such as in central nervous system (CNS)-driven behaviors, in a very powerful way ( Oh and Cheon, 2020 ).…”
