Scientists are constantly searching for new compounds and strategies to target and kill drug-resistant bacteria. By staying informed about these advancements, you can better understand the challenges we face in treating infections and the importance of responsible antibiotic use.
Now, let’s transition to the next section where we will explore immunology and the immune response.
Immunology and Immune Response
To truly understand the impact of immunology and the immune response, you need to grasp the intricate mechanisms by which your body defends itself against pathogens.
The immune system is a complex network of cells, tissues, and organs that work together to protect the body from harmful invaders. Immune system dysfunction can occur when this intricate network fails to function properly, leading to autoimmune diseases or increased susceptibility to infections.
Recent advancements in immunotherapy have shown promising results in treating various diseases, including cancer. Immunotherapy works by boosting the body’s natural immune response to target and destroy cancer cells. This approach has revolutionized cancer treatment and has the potential to transform the field of medicine.
