disease mechanisms

Disease mechanisms refer to the biological processes that lead to illness in the body. They involve the interactions between various factors, such as pathogens (like viruses or bacteria), genetic predispositions, and environmental influences. When these factors disrupt normal bodily functions—like immune response, cell signaling, or organ operations—disease can occur. For instance, a virus may invade cells, reproduce, and damage tissues, leading to symptoms. Understanding these mechanisms helps researchers develop treatments and preventive measures for various diseases, emphasizing the complexity of how health can be impacted on multiple levels.
