In the disease I study, it is a result of your own immune system attacking your body. That’s why it’s called an autoimmune disease. Type 1 diabetes and rheumatoid arthritis are also autoimmune diseases, where specific tissues in the body are destroyed by the immune system.
Diseases might be caused by a variety of factors including external sources, such as infectious disease, or it may be caused by internal dysfunctions, such as autoimmune diseases. There are diseases created by malicious people – I’ll talk about that later. Some diseases are caused by micro-organisms like bacteria, viruses or fungi. It is important to understand that only less than 1% of bacteria are infectious (the rest is totally harmless and actually we wouldn’t be able to leave without them) and that 1% infectious bacteria have nothing against humans. As a part of their nature they have to live in other organisms to stay safe, and reproduce. Also bacteria -if they can- wouldn’t kill their host because they would be the ones eventually affected once their host is dead.
Sometimes we can unintentionally create new diseases. For instance hospital acquired infection is a man-made one. Decades of irresponsible use of antibiotics forced simple gram negative bacteria to become one of the toughest bacteria in the world by gaining multi resistance to majority of the antibiotics. We now realized what we have done and doctors are trying to take all the precautions but it still takes between 100,000 -200,000 lives each year. We know very well how the hospital-acquired infections are “created”: over-prescription and poor patient compliance with antibiotic therapy, and the routine use of antibiotics as growth promoters in livestock feed formulas. These practices applied such an intense selection pressure to bacterial populations, killing out %99.9 (as doctors proudly said), and leaving resistant survivors which has become today’s killing machines.
My project relates to cancer and allergy. Cancer is caused from damage to DNA. The type of cancer, how bad it is, how much it progresses and your likely outcome all depend where the damage is. Most cancers are not from one single point of damage but multiple points of damage all contributing to the development of the cancer.
Allergy comes from your immune system over reacting. There are different types of allergic responses but they all involve inflammation. No one really knows why we have allergies. Like cancer there are a lot of different genes involved. Some people think we have allergies because we are too clean and our immune system isn’t trained properly. But this needs much more research before we know for sure!
