Studies of the multifunctional protein p11 (also known as S100A10) are shedding light on the molecular and cellular mechanisms underlying depression. Here, we review data implicating p11 in both the amplification of serotonergic signalling and the regulation of gene transcription. We summarize studies demonstrating that levels of p11 are regulated in depression and by antidepressant regimens and, conversely, that p11 regulates depression-like behaviours and/or responses to antidepressants. Current and future studies of p11 may provide a molecular and cellular framework for the development of novel antidepressant therapies.

Enhancing predictive accuracy for antidepressant response in depressive disorders: The additive value of interleukin-1β and interleukin-6 alongside hsCRP.

Department of Psychiatry, Chonnam National University Medical School, Gwangju, Republic of Korea.
Background: This study aimed to evaluate the potential additive effects of measuring serum interleukin-1 beta (IL-1β) and interleukin-6 (IL-6) on enhancing the predictive value of baseline serum high-sensitivity C-reactive protein (hsCRP) levels for predicting 12-week antidepressant treatment responses in patients with depressive disorders.
Methods: Serum levels of hsCRP, IL-1β, and IL-6 were measured at baseline in 1086 outpatient participants diagnosed with depressive disorders. Participants initially received monotherapy with antidepressants for the first three weeks, followed by a naturalistic, stepwise pharmacotherapy regimen administered every three weeks up to 12 weeks.

Treatment for major depressive disorder (depression) often has partial efficacy and a large portion of patients are treatment resistant. Recent studies implicate reduced somatostatin (SST) interneuron inhibition in depression, and new pharmacology boosting this inhibition via positive allosteric modulators of α5-GABAA receptors (α5-PAM) offers a promising effective treatment. However, testing the effect of α5-PAM on human brain activity is limited, meriting the use of detailed simulations.

Article Synopsis
- There is growing interest in using psychedelics like psilocybin to treat hard-to-manage psychiatric disorders, but little is known about how the experiences they create affect mood afterward.
- In experiments with mice, it was found that psilocybin increased head-twitch responses more in females than in males, highlighting a sex difference in its effects.
- Stress exposure during or after taking psilocybin impacted anxiety-like behavior in males, blocking its calming effects, while females only experienced a partial effect, suggesting that both sex and the context of the experience are important in understanding the drug's impact.
