Natural Killer Cells

HOW NATURAL KILLER CELLS WORK
A: NK cells are in constant circulation in the bloodstream, bumping into other cells in an attempt to detect invaders, such as viral or tumor cells.
B: When they collide with invaders, receptors on the NK cell surface identify dangerous proteins or antigens produced by the foreign cells.
C: These antigens trigger an attack from the NK cell. It activates F-actin, a group of bundled, polarized polymers that stabilize the NK cell’s attachment to the foreign cell’s membrane.
D: The NK cell releases lytic granules from its microtubule-organizing center (MTOC). These killer granules pass into the foreign cell and trigger cell death.
E: Natural killer cells can be extracted from donors, expanded in the lab, and infused directly into patients.
The Spring/Summer 22 cover art was created in a freeware 3D program called Blender. Like all 3D programs, Blender has a steep learning curve but once you get it down you can do some amazing things. And, since it is freeware, a lot of people have developed plugins for it that add special functionality. The 3D model is output as several render passes which are then brought into Photoshop and a composite illustration is created. Below are a few screen shots and several in process shots.
The interior art was done in Adobe Photoshop using a Cintiq 27QHD.
