Autoimmune disease is the result of the body's immune system targeting and attacking its own tissues in the same way that it would normally tackle infection. The tissues affected become inflamed and damaged.
The city of Venice is a major center of culture and tourism in Italy, a country in southeastern Europe. It is famous for its beautiful canals, palaces, and art. The city is built on more than 100 small islands.
Italy weather varies remarkably from region to region. Venice is situated on the north Italian plain, an very low-lying, flat region which has its own distinctive climate. In winter, the weather in this area is surprisingly cold - sometimes colder than Paris or London - and fog is an accepted part of everyday life.
