Vinculin is a simple adapter protein right? Wrong!

That’s been the prevailing view for the 46 years since it was discovered.

Here we provide a new paradigm and show that vinculin is a complex mechanosensor itself, containing 6 binary switch domains.

The mechanical response of vinculin
Vinculin buffers force via dynamic domain unfolding/refolding under physiological load and lacks a stable head-tail lock.

10/10 EC-specific deletion of STING or a global deletion of STAT1 not only block the interferon-like response, but decrease the severity of the response to LPS
9/10 The transcriptional response involves IRF1, through a mechanism we do not yet fully understand
8/10 In parallel, IL-6 leads to mitochondrial dysfunction and mtDNA release that leads to cGAS/STING signaling
7/10 Notably, this response does not require an autocrine IFN signaling, but is a direct transcriptional response to IL-6
6/10 In vitro work showed that IL-6 leads to an IFN-like response that requires expression of STAT1, but not the canonical STAT3
5/10 This IFN signature was further increased by the deletion of the IL-6 signaling inhibitor SOCS3 in the endothelium
4/10 Analysis of the response to LPS suggested a strong interferon activation
3/10 This enables great enrichment of endothelial RNA
2/10 To better understand how endothelial cells respond to a cytokine storm, we performed endothelial-specific translating ribosome affinity purification (TRAP) on endotoxemic mice
1/10 Shock drives vascular dysfunction, with in turn leads to organ injury and potentially death, by inducing a ‘cytokine storm’. Chief among them, IL-6 is an excellent marker for septic shock severity and predicts for mortality
Here's a quick thread with pics summarizing the paper. Many thanks for all the hard work at Albany Med and by our collaborator Pilar Alcaide!
Very proud of this work that is now out on JCI describing a new #signaling pathway downstream of the #cytokine IL-6 in the #endothelium with implications in #sepsis and #shock. Short thread with a summary coming later today.
For now just enjoy that gorgeous image taken by my student Fatma Awadalla!
Systemic shock can lead to vascular dysfunction and organ failure.

The BICAR-ICU-2 trial just dropped!

RCT involving IV bicarb in metabolic acidosis among patients with mod-severe AKI

Bicarb didn't affect mortality but it reduced the need for dialysis & risk of bacteremia

VERY similar conclusions to BICAR-ICU-1

Add your name ✍ at www.nycures.org so Albany sees 10,000 scientists calling for the future of biomedical research to be built right here in New York.

Our first email to members goes out soon—introducing the statewide biomedical institute we’re proposing and how you can help power it forward.
Impressive demonstration of how a leukocyte separates the two ECs to squeeze by.
Time to update my TEM lecture slides!

Staff members at the NIH seem to have done the impossible: spend the agency's $48 billion budget.

“Everyone has been rallying together to clean up the mess, but it’s a mess that did not need to be made,” an NIH program officer told me.
