Cellular injury in serious diseases is a big problem that can be hard to understand. It happens because of different reasons that damage how cells work. Here are the main causes:
Lack of Blood and Oxygen: When blood flow is low, cells don't get enough oxygen. This leads to a shortage of energy (ATP), which can cause cells to die. Cells can survive without oxygen for a little while, but eventually, they get hurt beyond repair.
Oxidative Stress: Sometimes the body makes too many harmful particles called reactive oxygen species (ROS). These can overpower the body's natural defenses, causing damage to fats, proteins, and even DNA. This creates problems for the cells and can lead to cell death.
Toxic Build-up: When the body breaks down energy without enough oxygen, it creates waste products like lactic acid. This waste can make the area around cells more acidic, which is bad for their health.
Inflammation: When the body gets hurt, it can have an extreme immune response. This means it releases substances called cytokines and chemokines that can cause even more harm to the tissues.
Too Much Calcium: If the balance of calcium in cells is disrupted, it can lead to the activation of harmful enzymes. These enzymes can break down important parts of the cell, making the injury worse.
Dealing with these issues is not easy. It's important to know when and how to treat cell injuries. Treatments might involve restoring blood flow, reducing oxidative damage, or controlling inflammation. However, creating effective treatments is challenging since many factors are involved. To find solutions, researchers from different fields need to work together and keep studying how to help cells recover better.
