Most diseases don’t start in the bloodstream.
               They start at the borders—gut, lung, skin, nasal passages—
               where pathogens invade and inflammation begins.


               Delivering antibodies directly to these surfaces opens up a
               different kind of therapeutic logic:

                   •  Neutralize pathogens before they enter
                       circulation
                   •  Suppress inflammatory signals at the site of
                       origin
                   •  Avoid systemic exposure—and systemic immune
                       rejection

               Oral antibodies don’t have to be absorbed to work. They
               can function right where they’re delivered, binding to
               microbial antigens, cytokines, or epithelial receptors in the
               gut lumen or mucosal lining.


               This is a shift from systemic control to local
               intervention—with major implications for safety,
               tolerability, and immune compatibility.




               How Plants Are Making Oral Antibodies Possible


               Antibodies are notoriously difficult to express outside of
               mammalian systems because of their size, glycosylation
               requirements, and multimeric structure. But plant
               expression systems—especially chloroplasts and
               endosperm-based platforms—are catching up fast.

               What makes this feasible:
