Summary
The study proposes a cognitive paradigm in immunology, suggesting preformed internal images, not just clonal selection, guide immune responses. These internal images, like infection and self, shape the immunological homunculus.
Area of Science:
- Immunology
- Cognitive Science
Background:
- The clonal selection theory has limitations in explaining immune system regulation.
- A cognitive paradigm offers an alternative framework for understanding immune responses.
Purpose of the Study:
- To clarify the nature of "internal images" proposed in a cognitive immunology paradigm.
- To illustrate these internal images using examples of infection and self-recognition.
Main Methods:
- Conceptual analysis of existing immunological paradigms.
- Elaboration on the "image of infection" and "image of self" concepts.
Main Results:
- Internal images are proposed as preformed structures that guide and restrict clonal activation.
- The "immunological homunculus" serves as a concrete example of these internal images.
Conclusions:
- A cognitive paradigm, utilizing internal images, provides a new perspective on immune system function.
- This framework may offer a more comprehensive understanding of immune regulation and self/non-self discrimination.

Cell-mediated Immune Responses
Overview
Cells of the Adaptive Immune Response
The T and B lymphocytes of the adaptive immune system develop from common lymphoid progenitor cells in the bone marrow. These progenitors give rise to precursors that eventually develop into both T and B lymphocytes. As these precursors mature, they gain the ability to detect and respond to foreign antigens in the body, a process known as immunocompetence. Additionally, these precursors acquire self-tolerance, a process that ensures they do not react to self-antigens. This intricate system...
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.
Complete Antigens
Complete antigens possess both immunogenicity and reactivity.

B Cell Activation and Differentiation
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.
When naive B cells encounter a specific antigen that can bind to the B cell receptor (BCR) on their surface, they undergo sensitization to respond to the antigen's presence. Sensitization begins with...

Immunological Memory
Immunological memory, a pivotal pillar of the adaptive immune system, is responsible for the body's ability to remember and respond more swiftly and effectively to previously encountered pathogens. This remarkable feature is what makes vaccines so effective in preventing diseases.
What is Immunological Memory?
Immunological memory is an integral function of the immune system that allows it to recognize and react more rapidly and effectively to pathogens previously encountered. This feature is...

Concepts and Prototypes
The human nervous system handles vast amounts of information by translating sensory stimuli into neural impulses, which the brain processes, creating thoughts expressed through language or stored as memories. The brain also synthesizes information from emotions and memories, which significantly influence thoughts and behaviors. This intricate process creates a comprehensive mental picture.
