Strands of DNA-like thread coil, loop, and spill upward, evoking the genome's dynamic three-dimensional architecture within the nucleus of a living cell. This special issue, with papers in Science and Science Advances, features single-cell and multiomic studies from the National Institutes of Health Common Fund's 4D Nucleome Program, which examines a fourth dimension of nuclear organization—how this folded structure shapes cell identity, shifts across development and aging, and goes awry in disease.

🔋 Mitochondria run their core power system using bacterial-style DNA. 🧬 But they need your nuclear DNA for support, repair, and growth. Think of it like a battery with its own mini-engine — it sparks on its own, but the car (your cell) builds and maintains it. Bottom line: Mitochondria are semi-independent — powered by ancient bacterial genes, guided by your human ones.

Let’s take a closer look at this protein structure determined using AlphaFold2. This protein structure is part of a huge molecular structure in the human body. More than a thousand proteins form a pore through the membrane surrounding the cell nucleus. Animation: ©Terezia Kovalova/The Royal Swedish Academy of Sciences #NobelPrize

The most detailed 3D reconstruction of a cell ever created. Blows my mind every time. But what exactly are we looking at here? The average human cell contains: ~ 15-20 total distinct organelle types, totalling between ~1-10 million working together per cell. All these nano-machines in the cell are made up of proteins. ~ 8,000-10,000 distinct types of unique proteins, adding up to between 40 million - 10 trillion total proteins making up all those cellular systems. ~ 10,000 - 15,000 distinct types of RNA shuttling information around the cell, totalling up to ~10 million RNA molecules moving around the cell simultaneously. ~ Billions of Lipid molecules packed together into the cell membrane, which is also packed tightly with millions more protein-based nano-machines. And let's not forget billions of lines of DNA information to build and run it all. That's TRILLIONS of of individual molecular pieces working together to make a single cell function. That means there is more complexity in a single cell than humanity's largest cities. And people still believe this wasn't Divinely Designed. This is God's Glory on Display. But to make the point. A cell couldn't have evolved from some nebulous simpler "protocell" because even the simplest cells still require massive complexity. The "simplest" cell ever created was engineered by scientists knocking out pieces of a functional cell until it stopped functioning. Here is what they found is the absolute necessary minimal requirements of a cell to function: - Over ~531,000 lines of coded DNA information - 473 total genes to create hundreds of unique protein products (they later added 19 genes back in because the cell was so weak) - Hundreds of thousands of total proteins all working together - Extensive regulatory networks guiding all these interactions If the cell doesn't have all these systems in place, from the start... it doesn't live. Cell rely on an intricate network of complex systems, which are themselves built from complex interconnected pieces woven together into an incomprehensibly complex web of functionilty. Only intelligence has ever been observed creation vast interconnected systems like this. Life was clearly Created. It couldn't happen any other way.

The axonal cytoskeleton and other components. The structural support is provided by spectrin and actin near the cell membrane. Microtubules, form tracks and motor proteins utilize them. A real axon is far more complex, housing essential structures like mitochondria.

#FluorescenceFriday #cellbiology #immunology #Actin dynamics at the immunological synapse (IS) between a Jurkat T cell and an antigen-presenting coverslip, as seen by total internal reflection structured illumination microscopy (TIRF-SIM). John Hammer's group #NIH used our TIRF-SIM to show that formins rearrange inward flowing actin filaments from the outer lamellipodial band of the IS into circumferential arcs that establish the peripheral supramolecular activation cluster, which in turn concentrates T cell receptor microclusters at the center of the IS.
