Had the joy of being a keynote speaker at the NYC Student Research Conference at Stuyvesant for a gathering of students from schools across New York City. The depth and curiosity they brought to every question was inspiring. Thanks for the invitation to meet these brilliant minds. #NYC #science

James D. Watson, Co-Discoverer of the Structure of DNA, Is Dead at 97

His legacy is irrevocably tainted by misogynist and racist statements. We should remember both the science and the harm. I, for one, will remember Rosalind Franklin more.

Don't miss the amazing line-up of talks in the 'Ageing and Adult Disease Models' session at #ZDM18. Featuring Caghan Kizil
@cakizil.bsky.social who will be speaking about 'Blood-Brain Barrier Pathophysiology and Therapeutic Opportunities in Alzheimer’s Disease' #zdmsECI #ZDMSociety

Congratulations to all authors! This work was supported by several federal and private research grants. We thank the patients and families for their participation.

... isogenic iPSC-derived human cells, mouse models, and #human brain tissues show the universal importance and validity of these disease pathways. Targeting these pathologies may open promising therapeutic avenues to slow #Alzheimer’s disease progression.

This rigidity may exacerbate the breakdown blood-brain barrier, an important structure regulating the clearance and basic health of the #brain. Our results provide further evidence linking vascular pathology to AD progression. Our validation in other large cohorts, ++

We identified unique molecular changes in various cell types that regulate the interaction between brain cells and blood vessels. An important cell type, #astrocytes, adopt a hyper-adhesive, mechanically rigid states at the #vascular interface with #APOE-ε4.

Single-nucleus multiomics in brains from Hispanic individuals reveal APOE-ε4-driven disruption of focal adhesion signaling in the presence of cerebrovascular pathology The apolipoprotein E4 allele (APOEϵ4) is the strongest genetic risk factor for late-onset Alzheimer's disease (AD), yet its molecular impact on cerebrovascular biology remains inconclusive, particular...

#2024Recap
2024 was an amazing year for #KizilLab with impactful publications, awards, patent applications, and discoveries with #zebrafish. These wouldn't be possible without our excellent team, collaborators, supporters &
@columbiauniversity.bsky.social. Big thanks! 💙 Looking fwd to more in 2025!🌟

Wherever you are and whichever of the diverse celebrations you observe today, 🎄 Merry #Christmas , 🕎 Happy #Hanukkah, 🕯️ Happy #Kwanzaa, 🌞 Blessed #Yule and any other holiday you celebrate this season.This must remind us of the shared values of humanity and unity in diversity. #HappyHolidays

Using X/Twitter data from nine countries, a study in Nature Communications shows that out-group mentions use more toxic language than in-group mentions, and political mentions are more toxic than apolitical mentions. https://go.nature.com/417N7KG 🧪

Thank you Jingli🥰

🚨 Our new study out in @natureportfolio.bsky.social! 🌟
We identify the "little brain" of the heart: the intricate intracardiac nervous system (IcNS) of zebrafish! 🐟

More about how this changes what we know about heart functionality.

This was a collaborative effort from teams at @karolinskainst.bsky.social and @columbiauniversity.bsky.social. Congratulations to all authors, including our own @elanuryilmaz.bsky.social and Prabesh Bhattarai! 🙌

Thanks for the generous support of our funding agencies 🙏

Why it matters:
This research challenges the idea that the heart is just a simple relay, positioning the IcNS as a key player in rhythm generation. A leap toward new therapeutic strategies for arrhythmia and heart failure.

🔑Highlights:
- Pacemaker-like neurons in the IcNS, generating rhythmic activity autonomously 🧠💓
- A complex diversity of neurotransmitter systems finely tuning heart rhythms 🔬
- Ex-vivo study of intact neural heart networks 🧪

ABCA7-dependent induction of neuropeptide Y is required for synaptic resilience in Alzheimer’s disease through BDNF/NGFR signaling In this study, Tayran et al. investigate the role of ABCA7, certain genetic variants of which act as risk factors for Alzheimer’s disease (AD), using a zebrafish AD model. They demonstrate that ABCA7-...

Study Shows How Common Genetic Variants in Black Americans Increase Alzheimer’s Risk Variants of the ABCA7 gene accelerate neurodegeneration by reducing the amount of neuropeptide Y, a protein essential for maintaining brain synapses.

Changes in ABCA7 gene links to a greater risk of Alzheimer’s, but it was unclear how the variants advance the disease. We have discovered how variants of the ABCA7 gene, which are common among Black Americans, increase the risk for Alzheimer’s.

We found a genetic variant that protects against Alzheimer’s disease We discovered a genetic variant that reduces the odds of developing Alzheimer’s disease by up to 70% and may be protecting hundreds of thousands of people from the disease. The discovery of the pro…
