Definition:

Pathobiology is the branch of biology that studies disease processes, including their causes, development, progression, and effects on the body.
It is a combination of two words:

• Patho = Disease

• Biology = Study of life

Simple Definition:

Pathobiology is the study of biological mechanisms behind diseases and how they affect organs and systems.

Key Areas in Pathobiology:

1. Causes of Disease (Etiology):

   • Infections, genetic defects, environmental factors

2. Mechanism of Disease (Pathogenesis):

   • How diseases start and spread in the body

3. Effects on Organs/Tissues:

   • Changes in cells, tissues, and functions of body parts

4. Diagnosis and Classification:

   • Microscopic and molecular study of diseased tissues

---

Example Fields Using Pathobiology:

• Cancer Biology

• Immunopathology (Immune-related diseases)

• Neurodegenerative Diseases (like Alzheimer’s)

• Infectious Diseases (bacteria, viruses, etc.)

---

Why is Pathobiology Important?

• Helps in early diagnosis of diseases

• Assists in drug development and treatment plans

• Enhances understanding of how diseases work
