*Animal Study | |||
*Accumulating evidence indicates that nicotinic receptor subtypes are altered in the brains of autistic individuals, and nicotinic acetylcholine receptors (nAChRs) play essential roles in autistic profiles in BTBR T+ Itpr3tf/J mice. | |||
*Biochemical analysis showed that nicotine had significantly decreased the concentration of inflammatory cytokines, including TNF-α, IFN-γ, IL-1β, and GM-CSF in the serum, and reduced the expression levels of intracellular pro-inflammatory cytokines (IL-17 & IFN-γ) on CD4+ and CD8+ T cells in the blood while mecamylamine reversed the effect of IL-17+ CD4+ T cells. | |||
*Nicotine administration up-regulated the expressions of α7, α4, and β2 nAChRs in the prefrontal cortex in BTBR T+ Itpr3tf/J mice. | |||
*The current results indicate that nAChRs play a significant role, at least in part, in ASD and might serve as a crucial target for therapeutic interventions in ASD. | |||

* Nicotinic receptors are distributed throughout the central and peripheral nervous system. Postmortem studies have reported that some nicotinic receptor subtypes are altered in the brains of autistic people. | ===2020: [https://pubmed.ncbi.nlm.nih.gov/32691528/ The Role of Nicotinic Receptors in the Attenuation of Autism-Related Behaviors in a Murine BTBR T + tf/J Autistic Model]=== | ||
* Recent studies have demonstrated the importance of nicotinic acetylcholine receptors (nAChRs) in the autistic behavior of BTBR T + tf/J mouse model of autism. This study was undertaken to examine the behavioral effects of targeted nAChRs using pharmacological ligands, including nicotine and mecamylamine in BTBR T + tf/J and C57BL/6J mice in a panel of behavioral tests relating to autism. | *Animal Study | ||
* Overall, the findings indicate that the pharmacological modulation of nicotinic receptors is involved in modulating core behavioral phenotypes in the BTBR T + tf/J mouse model. | *Nicotinic receptors are distributed throughout the central and peripheral nervous system.

* LAY SUMMARY: The involvement of brain nicotinic neurotransmission system plays a crucial role in regulating autism-related behavioral features. In addition, the brain of the autistic-like mouse model has a low acetylcholine level. Here, we report that nicotine, at certain doses, improved sociability and reduced repetitive behaviors in a mouse model of autism, implicating the potential therapeutic values of a pharmacological intervention targeting nicotinic receptors for autism therapy. | *Recent studies have demonstrated the importance of nicotinic acetylcholine receptors (nAChRs) in the autistic behavior of BTBR T + tf/J mouse model of autism.
