Immunological Memory01:23

Immunological Memory

17.6K
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...

Immunodeficiency Diseases

2.7K
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...

Hypersensitivity Reactions: Delayed Hypersensitivity Reactions01:29

Hypersensitivity Reactions: Delayed Hypersensitivity Reactions

105
Delayed-Type Hypersensitivity (DTH), or Type IV hypersensitivity, is a cell-mediated immune response. It occurs when T cells, rather than antibodies, mediate a reaction to specific antigens. It is characterized by a delayed onset (1-2 days) and involves the recruitment of macrophages to the inflammation site.The initiation of a DTH response begins with the sensitization of T cells. During this phase, which lasts at least 1-2 weeks, antigen-specific T cells are activated, clonally expanded, and...

Active versus Passive Immunity01:31

Active versus Passive Immunity

11.7K
Immunity, along with the ability to limit pathogen growth to prevent significant body tissue damage, can be gained either by (1) actively developing an immune response within the individual after exposure to a pathogen or after getting vaccinated or (2) passively transferring immune components from an immune individual to one who is nonimmune. Both these forms of immunity can be found naturally and in medical practices.
Active Immunity
Active immunity refers to the resistance one develops...

Cells of the Adaptive Immune Response01:23

Cells of the Adaptive Immune Response

9.8K
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...

  • Network science
  • Epidemiology
  • Computer science

Background:

  • Contagious phenomena like rumors and diseases spread through networks.
  • Network immunization is crucial for mitigating propagation.
  • Previous immunization strategies lack adaptability and effectiveness due to static approaches.

Purpose of the Study:

  • To develop a novel and adaptive vaccine placement strategy for network immunization.
  • To enhance the protection of healthy nodes against contagious spread.
  • To improve the efficiency of limited resource allocation in immunization efforts.

Main Methods:

  • Utilizing real-time node status as dynamic auxiliary information.
  • Comparing vaccine performance across different transmission time slots.
  • Developing an adaptive immunization scheme based on feedback and changing network dynamics.

Main Results:
