👉 PD-Infection, or Pathogen-Induced Inflammatory Response, refers to the body's immune system's reaction to an invading pathogen such as bacteria, viruses, or fungi. When these pathogens enter the body, they trigger an inflammatory response characterized by increased blood flow, swelling, and the recruitment of immune cells like neutrophils and macrophages to the site of infection. This response aims to contain and eliminate the pathogen, but it can also lead to tissue damage and systemic inflammation if the infection is severe or prolonged. PD-Infection is a critical aspect of immunology, highlighting the delicate balance between effective pathogen clearance and preventing excessive tissue harm.
