Chronic alcohol use reshapes the brain's immune landscape, driving anxiety and addiction

(Scripps Research Institute) Deep within the brain, a small almond-shaped region called the amygdala plays a vital role in how we exhibit emotion, behavior and motivation; it's also strongly implicated in alcohol abuse. Now, for the first time, a Scripps Research team has identified important changes to anti-inflammatory mechanisms and cellular activity in the amygdala that drive alcohol addiction.

Abstract The central amygdala (CeA) is a critical regulator of emotional behavior that has been implicated in psychiatric illnesses, including anxiety disorders and addiction. The CeA corticotropin releasing factor receptor 1 (CRF1) system has been implicated in alcohol use disorder (AUD) and mood disorders, and has been shown to regulate anxiety-like behavior and alcohol consumption in rodents. However, the effects of CRF signaling within the CRF receptor 1-containing (CRF1+) population of the CeA remain unclear, and the effects of ethanol and CRF1 manipulations in female rodents have not been assessed. Here, we ...

The West Vancouver (Canada) police officer rang the doorbell of my house on Cypress Creek on a fine Tuesday afternoon in April. He told me that a citizen had seen me driving "wildly" the previous Friday afternoon on the Upper Levels Highway and handed me a letter. I thought back to that day. It had started with a large goblet of Chardonnay while making the kids' breakfast. I drove them to school, returned to the house and continued with the white wine. Then I got into the cocaine. Then I was too wired to do anything so I popped a Zopiclone, a tiny blue pill that is guaranteed to put me to sleep ...

CONCLUSIONS: Our results suggest that the Amazonian medicine-based therapy attracts a diverse patient group not limited to regional residents and may be particularly appealing to more impaired SUD patients with a history of unsuccessful treatment. The sample's cultural diversity suggests an existing interest in such therapies among international SUD treatment-seeking patients. These findings are relevant in light of the need for improved SUD therapies and contribute to the emergent research literature on ayahuasca-based treatments. PMID: 32800077 [PubMed - in process]

This study aimed to contribute to this line of research by examining the moderating effect of depression, bipolar spectrum disorder, borderline personality disorder and social anxiety disorder on the association between PBS and alcohol outcomes. Participants (N = 4,960; mean age = 25.43) were young men participating in the Cohort Study on Substance Use Risk Factors. Measures of PBS use, typical drinks per week, alcohol-related consequences, depression, bipolar spectrum disorder, borderline personality disorder and social anxiety disorder were used from the second follow-up assessment. Main results indic...

CONCLUSION: We hypothesize that persistent alcohol drinking may contribute to disruption of the normative association between interoception and pain. Future studies should be conducted to develop knowledge on this association and to investigate its possible therapeutic significance and implications.

In this study, our endeavor was to determine if social isolation during adolescence (aSI) was as efficient as MS to facilitate alcohol intake; and moreover, if their combination (MS + aSI) induces even higher alcohol intake and exacerbates anxiety-like behaviors. Also, we evaluated dopamine and endocannabinoid receptors in the NAcc to describe potential changes caused by MS, aSI or both. Wistar rats were reared under 4 different conditions: non-MS + social housing (SH), MS + SH, non-MS + aSI and MS + aSI. Once these rats became adults they were submitted...
