Lymphocytes are a type of white blood cell. There are two types of lymphocytes of the acquired immune system: T cells and B cells. There is a third type of lymphocyte known as natural killer (NK) cells, but these are a part of the innate immune system.
A Very Brief History. The original Bengal cats are a hybrid of the Asian Leopard Cat and domestic cats. They were developed by various people, most notably Jean Sugden Mill, in the 1970s and 80s with the aim of harnessing the beauty of the wild cat, yet maintaining the temperament of the domestic cat.
The Bengal breed originated as a human-made hybrid of the Asian leopard cat and the domestic cat. The leopard cat (Felis bengalensis ) is a cat-sized inhabitant of southern Asia and is thought to be one of the closest of the modern undomesticated cat species to the ancient common ancestor of the cat family.
