Excited to see this study from @darshanakapri out in @npp_journal showing norepinephrine regulates mitochondria within hippocampal neurons via a β2-AR–Gs-cAMP–PKA-PGC-1α cascade, suggesting links between NE effects on mitochondria and cognition. www.nature.com/articles/s41...

This suggests multiple critical period windows in postnatal life wherein disruption of serotonergic neurotransmission could have opposing effects on mood, paralleled by differential molecular, cellular and bioenergetic consequences

It is difficulty to clear extrapolate the temporal windows tested here in rodents to precise equivalents in humans, but points to the possibility that exposure to SSRIs in distinct time windows of childhood and adolescence may exert long-lasting consequences.

This all adds to a body of literature that indicates very long-term effects across the life-span that emerge when serotonergic neurotransmission is disrupted in developmental temporal windows, and also highlights that timing of perturbation is key.

This phenotype is noted in male, but not female, rats and underscores the importance to looking carefully at long-term effects of early perturbations in both sexes.

Early exposure to Prozac evokes diametrically opposing effects on mood behavior, global gene expression, dendritic architecture and mitochondrial function in the prefrontal cortex which is long-lasting and persists well into adulthood.

Awhile back we started a Slack group for psychedelic science. Researchers used it to organize meetups and panels at conferences. We discuss papers, including a lively discussion now of the Lu et al. preprint. DM @mikaelpalner.bsky.social or I if you work in academia and want to join

A modern medicine mindset of a clear preference for single molecule therapeutics, has been widened to consider benefits of multi-targeted therapy - opening the path to use modern tools to investigate both the veracity, and mechanisms, of insights from indigenous knowledge systems.

Vidita Vaidya @viditavaidya.bsky.social · 09/04/2025

In the context of plant and fungi-derived natural products with psychoactive effects, there has been a recent resurgence of interest in their therapeutic utility to treat neuropsychiatric and neurodegenerative disorders - for eg. serotonergic psychedelics

My father continued to stay deeply engaged with this work from its conception uptil submission of the manuscript - there has been nothing more precious to me than this opportunity to collaborate with him - on a reverse pharmacology approach that he championed his whole life.

Our findings suggest that the stress resilience boosting effects empirically and clinically observed with Aswagandha root extract may involve the mitochondrial and bioenergetic actions of withania somnifera, mediated via WithanolideA and WithanosideIV through recruiting BDNF-SIRT1 signaling.

Vidita Vaidya @viditavaidya.bsky.social · 09/04/2025

Inspired by 'reverse pharmacology' which capitalizes on transdisciplinary insights from indigenous knowledge systems - we set out to ask if mitochondria and bioenergetics might be a key target in neurons - which could contribute to the putative neuroprotective effects of Ashwaganda

Vidita Vaidya @viditavaidya.bsky.social · 09/04/2025

In our study led by Sashaina Fanibunda, a collaboration between TIFR and MRC-KHS uncovered the potent effects of Withania somnifera on mitochondrial biogenesis and function in cortical neurons - driven via BDNF and SIRT1 signaling.

Many drugs are derived from the knowledge domain of natural products- with famous examples including the aspirin, digitoxin, taxol, quinine and artemesinin - highlighting the importance of continuing to explore plant-derived phytoactives using state of the art modern tools.

Withania Somnifera (Ashwagandha) has been used for centuries in Indian traditional medicine as an 'adaptogen' that boosts stress resilience, but the cellular mechanisms and key beneficial bioactives that drive putative neuroprotective effects remain unclear..

Thanks for highlighting our (@polybiotique.bsky.social) report and its coverage by @dyanilewis.bsky.social, Izzy. As we mention in our report, fixing this will require clearly earmarked resources, and importantly, the will and strong commitment to equity from the leadership in Indian academia.
