The enzyme becomes overactivated, producing a lot of citrullinated proteins, which are detected by specific antibodies. When bound to the joint proteins, such antibodies activate immune cells. This leads to the tissue injury caused by active immune cells and specific proteins called cytokines.

Rheumatoid arthritis (RA) usually starts with local inflammation, leading to (often small) damage to joints. Damaged joints release negatively charged polysaccharides called glycosaminoglycans, which activate the enzyme PAD4 (the main enzyme responsible for biochemical changes in RA).

It was the Austrian-Italian border; the fighting continued here from May 1915 until October 1917. Some 10,000 people died in this area.

Thank you, Stig! Especially when you think how many people died here during WWI. The ruins still stand.

And here is Tallinn:)
