T cells are our immune system's customised tools for fighting infectious diseases and tumor cells. On their surface, these special white blood cells carry a receptor that recognizes antigens. With the ...

Using cryo-electron microscopy (cryo-EM), researchers captured unprecedented images of key immune system receptors interacting with messenger proteins, elucidating how the receptors change shape upon ...

Scanning Electron Microscopy (SEM) has revolutionized the realm of microscopic analysis. By delivering astonishingly detailed images of minuscule entities such as insects, bacteria, or even the ...

Electron microscopy is a powerful technique that provides high-resolution images by focusing a beam of electrons to reveal fine structural details in biological and material specimens. 2 Because ...

LA JOLLA, CA - Jan. 18, 2016 - Many cells have microscopic gates, called ion channels, which open to allow the flow of ions across the cell membrane. Thanks to these gates, cells can detect stimuli ...

Yale scientists have discovered a family of immune proteins, which they describe as a “massive molecular machine,” that could affect the way our bodies fight infection. Our immune system mobilizes ...

Few standard optical microscopy methods can achieve the same level of spatial resolution, which is essential for being able to resolve geometric and structural features on the nanometer length scale.

Scientists at Scripps Research have devised a method that may be able to shortcut one of the big steps in modern vaccine development. The researchers showed that they could apply high-resolution, ...
