Psychoneuroimmunology: Cardiovascular Disease01:27

Psychoneuroimmunology: Cardiovascular Disease

367
Psychoneuroimmunology (PNI) is a multidisciplinary field that examines how psychological factors, particularly stress, interact with the immune system and impact physical health. Research in PNI has shown that chronic or traumatic stress can disrupt both the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system. These disruptions contribute to serious health conditions, including cardiovascular diseases.
A key area of focus in PNI is the relationship between stress and coronary...

Immunological Memory01:23

Immunological Memory

14.9K
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...

Introduction to Lymphatic and Immune System

Immunity is a crucial biological concept about our body's inherent capacity to prevent infections and diseases. A complex network of cells and tissues collectively known as the immune system facilitates this natural defense mechanism. The immune system plays an integral role in maintaining our health and well-being, shielding us from potential health threats.
The immune responses can be categorized into two types: innate and adaptive. Innate immunity comprises nonspecific defenses we are...

Introduction to Innate and Adaptive Immunity

8.4K
The human immune system is a complex defense mechanism that protects the body from harmful pathogens and foreign substances. It comprises two crucial components: innate and adaptive immunity.
Innate immunity is the body's natural, nonspecific defense system that acts quickly to protect against pathogens. It incorporates physical barriers like skin and mucous membranes and cellular elements such as phagocytes and natural killer cells. This part of our immune system provides an immediate,...

Special Features of Adaptive Immunity01:20

Special Features of Adaptive Immunity

2.8K
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,...

Area of Science:

  • Immunology
  • Cardiovascular Medicine
  • Inflammation Research

Background:

  • Systemic inflammation drives atherosclerosis and its complications.
  • Current anti-inflammatory therapies for atherosclerotic cardiovascular disease (ASCVD) carry risks of immune suppression.
  • Trained immunity, a form of innate immune memory, is implicated in chronic inflammation and disease progression.

Purpose of the Study:

  • To review the evidence for trained immunity in ASCVD.
  • To explore how risk factors induce trained immunity.
  • To discuss the role of trained immunity in vascular inflammation and guide future therapies.

Main Methods:

  • Literature review of studies on trained immunity and ASCVD.
  • Analysis of risk factors contributing to trained immunity.
  • Discussion of metabolic and epigenetic mechanisms.

Main Results:

  • Trained immunity is induced by risk factors like hyperglycemia, hypercholesterolemia, diet, stress, and infection.
  • This innate immune memory may sustain vascular inflammation in ASCVD.
  • Understanding these mechanisms is crucial for developing new treatments.

Conclusions:

  • Trained immunity is a significant factor in ASCVD development and progression.
  • Targeting trained immunity offers a precise immunomodulatory approach for ASCVD.
  • Further research into its mechanisms will enable next-generation therapies for ASCVD prevention and treatment.
