Summary
Intravenous immunoglobulin (IVIG) therapy benefits autoimmune and inflammatory diseases through complex immune system interactions. Understanding these mechanisms, involving Fc and F(ab')2 fragments, is key to identifying patient response biomarkers.
Area of Science:
- Immunology
- Pharmacology
Background:
- Intravenous immunoglobulin (IVIG) is a critical therapeutic agent derived from pooled donor IgG.
- It is extensively utilized for immunotherapy in various autoimmune and inflammatory conditions.
Purpose of the Study:
- To review the complex mechanisms of action underlying IVIG's therapeutic benefits.
- To explore how understanding these mechanisms can aid in identifying biomarkers for treatment response.
Main Methods:
- Review of experimental and clinical data on IVIG.
- Analysis of immune system components and soluble mediators affected by IVIG.
Main Results:
- IVIG exerts therapeutic effects through multiple, non-exclusive mechanisms.
- These mechanisms involve interactions with both soluble mediators and cellular components of the immune system.
- Both Fc and F(ab")2 fragments of IgG play roles in IVIG's action.
Conclusions:
- The therapeutic efficacy of IVIG is attributed to a complex interplay of immune modulatory functions.
- Further elucidation of IVIG's effector functions is essential for developing biomarkers to predict patient responses in autoimmune diseases.

When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.

01:29Autoimmune Disorders
2.0K
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

17.5K
An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function.
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...

17.4K
The inflammatory response is the body's defense against infection, injury, or irritation from bacteria, trauma, toxins, or heat. Inflammation helps locate and destroy pathogens and remove damaged tissue elements to heal the body. During this initial phase, fluid, blood products, and nutrients migrate to the injured area, resulting in redness, heat, swelling, ache, and loss of function. Moreover, signs of systemic inflammation include fever, increased WBC count, malaise, anorexia, nausea,...

8.4K
The immune system's inflammatory response destroys the invading pathogen, permitting the tissue to heal. The changes during the cellular and vascular stages allow exudate formation at the site of inflammation. The inflammatory exudate released from the wound has high protein content and a specific gravity above 1.020.
The typical wound exudate is odorless, transparent, straw-colored, thin, and watery. Exudate, however, can differ depending on the state of wound healing. Likewise, the...

The adaptive immune response, a sophisticated defense mechanism, relies on the activation and differentiation of B lymphocytes, or B cells. These processes enable our bodies to mount a tailored response against specific pathogens such as bacteria, free virus particles, toxins, and parasites.
