Immunodeficiency Diseases

1.1K
Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency...

Diversity of Antigen Receptors01:28

Diversity of Antigen Receptors

722
Antigen receptors are essential components of the immune system crucial in defending the body against foreign invaders. These receptors are present on the surface of B and T cells, enabling them to recognize antigens and mount an appropriate immune response.
Before encountering any antigen, lymphocytes express these receptors. On B cells, the antigen receptor is a membrane-bound antibody molecule called BCR; on T cells, it is a T cell receptor or TCR. B and T cell receptors are composed of two...

Antigens Involved in Adaptive Immunity01:26

Antigens Involved in Adaptive Immunity

614
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.

Special Features of Adaptive Immunity01:20

Special Features of Adaptive Immunity

972
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,...

Cells of the Adaptive Immune Response01:23

Cells of the Adaptive Immune Response

2.8K
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...

  • Immunology
  • Virology
  • Systems Biology

Background:

  • Local immunodeficiency (LI) is a recently observed phenomenon.
  • LI arises from antigenic cooperation among intrahost viruses.
  • These viruses form networks of cross-immunoreactivity (CR).

Purpose of the Study:

  • To analyze the effects of combining simple CR networks with a stable LI state.
  • To understand the dynamics and stability of interconnected viral networks.
  • To identify characteristics of CR networks at the boundary of stable LI.

Main Methods:

  • Computational modeling of CR networks.
  • Analysis of network connectivity and stability.
  • Investigation of viral interactions within interconnected CR networks.

Main Results:

  • Combining CR networks can lead to significant changes in viral roles within the network.
  • Borderline CR networks exhibit marginally stable LI states.
  • Some borderline networks feature independently evolving subnetworks despite overall connectivity.

Conclusions:

  • The combination of CR networks introduces complex dynamics, including altered viral functions.
  • Understanding the stability boundaries of CR networks is crucial for predicting LI.
  • Network modularity can persist even in interconnected systems, impacting immune responses.
