Study Notes
PHA2PGB - Introduction to Immunology
-
Immunology is the science of defense, studying the complex network of organs, cells, and proteins that protect the body from infection.
-
The immune system protects against infections using multiple lines of defence.
-
It is a complex system of organs, cells, and proteins that communicate to attack perceived microbial threats.
-
Dysfunction of the immune system can lead to various diseases like allergies, autoimmunity, and cancers.
Module Overview
-
Module 1: Overview of immunology, innate immunity, immune cells, and barriers.
-
Module 2: Pathogen recognition, cells involved in immunity, and inflammation.
-
Module 3: Antigen presentation, immune synapse.
-
Module 4: Immunopharmacology, innate immune system, and glucocorticoids.
-
Module 5: Cell development, clonal diversity, and tolerance.
What is Immunology and Why is it Important?
-
Immunology is crucial for understanding and treating diseases.
-
A faulty immune system can result in various diseases.
-
A functional immune system is essential for fighting off infections, even from normally harmless bacteria or pathogens.
The Immune system - what and how?
-
The immune system recognizes and combats threats like microorganisms and toxins.
-
It destroys pathogens and dysregulated self-cells (e.g., cancer cells).
-
It also repairs wounds.
-
The immune system operates in two branches: innate/natural and adaptive/learned.
The Immune System and Disease
-
The immune system's role is multifaceted, including defense against infections and tumors.
-
It is responsible for tissue regeneration and scarring, and plays a crucial role in response to injuries and inflammatory processes
-
Immunological dysfunction can lead to diseases like allergies, autoimmunity and various cancers.
-
The immune system is involved in organ/tissue transplantation, and the recognition of introduced or newly produced tissue proteins as foreign.
Defense Against Infection - Vaccination
-
Vaccination programs have drastically reduced infectious diseases.
-
Data collected from the US reveals significant declines in various preventable diseases following vaccination programs.
Pandemics are Recurrent
-
Pandemics are recurrent events throughout history impacting human populations.
-
Diseases like the Black Death, Smallpox, Spanish Flu, HIV/AIDS, Sars, MERS, Ebola and Covid-19 are examples.
Advances in Immunology and Immunopharmacology
-
Immunology advances have led to immunopharmacology.
-
Immunopharmacology studies the regulation of the immune system through pharmacological agents.
-
It focuses on developing methods to selectively modify immune function for disease treatment.
-
Immunopharmacology includes inoculations, autoimmune disorders, allergic reactions, and cancer.
Cell-Based Immunotherapy
-
Cell-based immunotherapy uses engineered or enhanced immune cells to fight diseases like cancer, infections, or autoimmune issues.
-
It involves manipulating the patient's own immune cells or donor cells to increase effectiveness in targeting and eliminating disease cells (e.g., cancer).
-
Techniques such as CAR-T-cell therapy, TIL therapy, engineered TCR therapy, and NK cell therapy are used to enhance or modify immune cells to fight disease more effectively.
Therapeutic Applications
-
Immunopharmacology has broad therapeutic applications for treating autoimmune diseases.
-
These applications extend to treating organ/tissue transplantation and cancer treatment.
-
Autoimmune Diseases: Includes thyroiditis, myasthenia gravis, type I diabetes, glomerulonephritis, and rheumatoid arthritis, also relevant to organ and tissue transplantation.
-
Cancer: Immunopharmacology plays a crucial role in cancer treatment and treatment of tumors.
-
Organ/Tissue Transplantation: Applications in preventing recipient immune rejection and promoting immune tolerance to transplanted organs, including kidney, heart, bone marrow, and islets.
Summary
-
The immune system is a complex network that defends against various threats.
-
Two major branches (innate and adaptive) of immunity provide broad coverage against infections and other threats.
-
It can also cause misguided responses to self-cells, which can cause autoimmune disorders or rejection of transplant organs.
-
Immunopharmacology research leads to better methods to selectively modify immune function, targeting diseases more effectively.
-
Continued advances in immunopharmacology fuel developments in vaccinations and disease treatments.
