The Tiny Machines That Shape Our Health and Future
Every process that defines life—every heartbeat, every thought, every breath—is driven by an astonishingly diverse workforce of molecular machines known as proteins.
These microscopic structures don't merely form our physical building blocks; they regulate, communicate, defend, and repair with precision that humbles our most advanced technology. From the hemoglobin carrying oxygen through your bloodstream to the antibodies defending against infection, proteins work tirelessly in every cell of your body.
Today, revolutionary advances are allowing scientists to see these nanoscale workhorses in unprecedented detail, revealing secrets that could transform how we treat diseases from cancer to aging itself.
Proteins are biopolymeric structures composed of chemical building blocks called amino acids, of which 20 are commonly found in biological chemistry. They act as structural support, biochemical catalysts, hormones, building blocks, and initiators of cellular death 4 .
Think of them as specialized tools in a cellular workshop, each perfectly designed for specific tasks.
In early 2025, researchers at Osaka University discovered a protein called AP2A1 that plays a key role in cellular aging 5 .
Suppressing AP2A1 in older cells reversed senescence and promoted cellular rejuvenation, while AP2A1 overexpression in young cells advanced senescence 5 .
The Seegar Lab's groundbreaking visualization required cutting-edge technology and meticulous experimental design:
The cryo-EM process enables visualization of protein structures at atomic resolution without leaving campus—a capability that has transformed structural biology 1 .
