LA JOLLA (January 8, 2025)—Human bodies defend themselves using a diverse population of immune cells that circulate from one organ to another, responding to everything from cuts to colds to cancer.

More than a decade ago, plant geneticists noticed something peculiar when they looked at grafted plants. Where two plants grew together, the cells of each plant showed signs of having picked up ...

Artistic rendering of cellulose biosynthesis with zoomed in view. Individual cellulose chains (dark brown) are synthesized by plasma membrane-bound (purple) cellulose synthase enzyme complexes (cream) ...

Scientists have created a new atlas of plant cells during immune response, in turn discovering a new rare cell state, called Primary IMmunE Responder (PRIMER), that acts as an immune response hub to ...
