Interferon are small proteins (cytokines) that enhance the immune system and defense against viruses and bacterial infections.
Interferon stimulates the infected cells and those nearby to produce proteins. These proteins prevent the virus from replicating within them. Further production of the virus is inhibited<span> and the infection is stemmed.
</span>There are three types of interferon: gamma, alpha and beta. Alpha and beta can be produced from any cell, and gamma is<span> produced only by natural killer cells and T lymphocytes. The main purpose of gamma interferon is to signal the immune system to respond to infectious agents or cancerous growth.</span>

The Phloem. ~ As it is the two way transport framework in a leaf.
In a leaf, there are two cylinders: xylem and phloem. The xylem conveys water and the phloem conveys minerals and starches.
There are two tissues inside those veins, xylem and phloem. Xylem conveys water from the roots up to the cells in the leaf. Phloem conveys the nourishment delivered in the leaf to the remainder of the plant. Primary concern is the leaf has veins for a similar explanation we have conduits and veins, to move stuff around to where we need it.
