Abstract
Autism spectrum disorders (ASDs) are neurodevelopmental disorders characterized by impairments in verbal and non-verbal communication, impaired social interactions and repetitive behaviors. There is evidence of a link between ASD symptoms and immune dysfunction, but few studies have been performed in adult patients to confirm this. In this work, we used flow cytometry to study immunological differences in peripheral blood mononuclear cells from 59 adult patients and 26 healthy control subjects to identify possible immune cell profiles related with this group of disorders. We analyzed six immune cell subpopulations (ie, B-cells, CD4(+) and CD8(+) T-cells, NK, NKT cells, and monocytes) and their corresponding stages of apoptosis and activation. The most noteworthy results showed that, compared to healthy controls, patients had increased percentages of CD8(+) T-cells and B-cells, and a decrease in the percentage of NKT cells. Regarding CD25 expression, we found overall CD25(+) overexpression, primarily in NK and NKT cells. Apoptosis percentage showed an increasing trend only in monocytes of patients. These data support a link between ASD and immune dysfunction, suggesting that specific cellular phenotypes and/or activation status of immune cells may be relevant in adult ASD.

Abstract
Maternal Bisphenol A (BPA) diet triggers anxiety in rodents, but the underlying mechanism is still unclear. Accumulating epidemiological and experimental data have demonstrated that the anxiety is associated with aberrant neuroimmune response. In this study, we found that maternal BPA diet (MBD) exacerbated anxiety-like behavior in female juvenile mice, and the molecular evidence further showed that this behavioral phenotype was connected to the neuroimmune activation, such as elevated tumor necrosis factor alpha (TNF-α) and interleukin (IL)-6 levels in prefrontal cortex (PFC) rather than in peripheral blood, which indicated that neuroimmune response might be ascribed to neuroglial activation because activated neuroglia cells could secrete proinflammatory cytokines. Subsequently, we found that ionized calcium-binding adapter molecule (Iba)-1 as a selective marker for microglia and glial fibrillary acidic protein as a specific marker for astrocyte were significantly increased at transcriptional and translational levels, which confirmed the neuroglial activation in this model. Therefore, we conclude that MBD induces excessive anxiety-like behavior in female juvenile with elevated TNF-α and IL-6 levels, as well as activated microglia and astrocyte in PFC. Herein caution must be taken to prevent potential risks from MBD becuase exacerbated anxiety-like behavior in female juvenile by MBD may be a critical contribution for subsequent growth or mental disorders.
