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.
Once a cat is four generations from a wild ancestor, the breed is a gentle and makes a great pet. Before the fourth generation, these cats are only kept in special conditions for breeding purposes and not to live with people as part of the family. Once far enough removed from the wild ancestor, the Bengal is an intelligent cat that has a genuine two-way relationship with its owners. They are very active around the house and like to take part in whatever is going on. They are also very athletic and agile, climbing and running for the fun of it.
