Disease mechanisms refer to the biological processes that lead to the development of diseases. These mechanisms can involve genetic factors, environmental influences, and interactions between cells and tissues. Understanding how diseases arise helps researchers identify potential targets for treatment and prevention. Different diseases may have unique mechanisms. For example, in cancer, abnormal cell growth occurs due to mutations in DNA, while in autoimmune diseases, the immune system mistakenly attacks the body's own cells. Studying these mechanisms is crucial for developing effective therapies and improving patient outcomes.
