Special Features of Adaptive Immunity

Special Features of Adaptive Immunity

The adaptive immune system, a crucial component of the overall immune response, offers a highly specialized defense against pathogens. It involves specific cell types and features, enabling it to combat infections effectively and efficiently.
The primary cell types involved in adaptive immunity are T cells and B cells. Each type has a unique role in defending the body against pathogens. T cells are responsible for cell-mediated immunity. They identify and eliminate infected cells directly,...

Antigens Involved in Adaptive Immunity

Antigens Involved in Adaptive Immunity

An antigen is any substance the immune system identifies as foreign and potentially harmful to the body, prompting an immune response. Antigens have two functional properties: immunogenicity and reactivity. Immunogenicity is the ability of an antigen to stimulate a specific immune response. At the same time, reactivity describes the antigen's ability to react with the cells and antibodies produced in response to it.

Autoimmune Disorders

Autoimmune Disorders

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.

Area of Science:

Immunology
Autoimmunity Research
Tolerance Mechanisms

Background:

Self-tolerance and autoimmunity are rapidly evolving fields.
Understanding these processes is crucial for developing new treatments.

Purpose of the Study:

To explore recent advancements in self-tolerance and autoimmunity research.
To highlight the development of new disease models and understanding of pathogenic mechanisms.

Main Methods:

Definition of tolerance induction mechanisms in T and B cells.
Creation of new genetically modified rodent models (transgenic rats and mice).
Precise identification of antigens and receptors for pathogenic lymphocytes.

Main Results:

Identified at least two mechanisms for tolerance induction in T and B cells.
Developed novel disease-susceptible (HLA-B27 transgenic rats) and disease-resistant (I-E/I-Ak NOD transgenic mice) strains.
Precisely defined antigens and antigen receptors for pathogenic lymphocytes in specific models.

Conclusions:

New knowledge significantly advances the understanding of self-tolerance and autoimmunity.
These findings are expected to lead to the development of more effective therapies for autoimmune diseases.
