M. J. Shleiden shifted the scientific community's attention to cellular processes with his

In 1883, the German botanist Matthias Schleiden came to the conclusion that all plants were built of cells, while the German zoologist Theodor Schwan, only a year later, concluded the same for animals.

Together they lay the foundation of the so-called cellular theory which represents a fundamental discovery in biology. This theory contains three basic postulates:

it enhances antibody production by t cells of the adaptive immune system.
