Did you know pathogenic bacteria can target inhibitory receptors to evade phagocyte responses? A recent study from our lab and that of Alex McCarthy (Imperial College) shows how Group B strep hijacks neutrophil LILRB3 to evade antibody-mediated immunity. 👇nature.com/articles/s41467-0…

In a #TopRead from @bvglab at @KStateResearch, data show that Efb-C binding to C3b exerts additional inhibitory effects on the central complement components beyond blocking formation of the C3 proconvertase alone. Learn more: ow.ly/yzsN50Z19xU.

Zymogen activation is a ubiquitous strategy for regulating enzyme activity. In our @jbiolchem paper led by @HuiquanDuan, we show that blocking this fundamental process is used to inhibit the first proteolytic event of the classical #complement pathway 👇 doi.org/10.1016/j.jbc.2025.1…

It's clear that many do not understand what @NIH-funded research does to improve health. It's time to revive a study published 10 years ago that provides incredible information about this. link in the comment Every single new drug approved by the FDA from 2010–2016 was built on NIH-funded research—that’s all 210 drugs. But what the public sees is just the tip of the iceberg. Pharma takes credit for the final product, but beneath each drug developed, there are ~20 years of basic research, and 90% of the cost is from basic research funded by the NIH, which discovers drug targets, understands disease mechanisms, and creates life-saving treatments. Figuring out how cancer evades the immune system, how addiction rewires the brain, and how heart disease develops is the role of the NIH, creating the foundation for the breakthrough drugs that come 20 years later, and the NIH does all that with only 0.8% of the US budget. Without NIH, there would be no cancer immunotherapy, no anti-overdose medication, no anti-heart attack or stroke medication, no cutting-edge treatments. If NIH funding is cut, the iceberg will melt. That means fewer cures, more suffering, and more lives lost. The science beneath the surface keeps us afloat. Invest in NIH. Invest in life

“from one stage to the next a greater amount of proenzyme is activated, and it may be suggested that the need to link the minute physical stimulus of surface contact with the final enzymatic explosion has resulted in the evolution of a biochemical amplifier” -RG Macfarlane, 1964

Yesterday a Nobel prize was given for alpha fold. Alpha fold could not exist without the Protein Data Bank (PDB), a public database funded by US taxpayers. Every structural biologist in the world that deposited their structure to the PDB indirectly helped train alpha fold.
