B cells are lymphocytes (a class of white blood cells) that play a large role in the adaptive immune system by making antibodies to identify and neutralize invading pathogens like bacteria and viruses. The human body can produce millions of types of B cells, each with a unique receptor protein. This allows protection against millions of possible pathogens—all the while recognizing those cells that are part of the body and are not to be attacked.

Minamoto no Yoritomo (源頼朝) (May 9, 1147 – February 9, 1199), was a Japanese warrior and clan leader who founded the bakufu, a system of feudal lords which governed Japan for seven centuries, and became the first shogun of the Kamakura Shogunate of Japan. The surviving heir of the Minamoto clan, which was crushed after the Heiji Rebellion in 1159, he lived in exile for twenty years before issuing a call to arms and rising up against the Taira clan. He established a headquarters in Kamakura, from which he began to organize the war lords and samurai into an independent government.
