Immunodeficiency Diseases01:25

Immunodeficiency Diseases

3.8K
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...

Pulmonary Tuberculosis I

1.7K
Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Chronic Inflammation: Introduction01:12

Chronic Inflammation: Introduction

51
Chronic inflammation is a prolonged, dysregulated immune response that persists for weeks to years when the inciting stimulus is difficult to eradicate or when self‑antigens drive ongoing reactivity. Morphologically, it is defined by mononuclear cell infiltration, progressive tissue destruction, and concurrent attempts at healing via angiogenesis and fibrosis. Compared with acute inflammation, edema is less prominent while cellular infiltration predominates; triggers include persistent...

Immune Response Against Viral Pathogens

2.4K
The immune system's response to viral infections is a complex and coordinated process involving natural killer (NK) cells, T cell-mediated responses, and antibody-mediated responses.
NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...

Drug Toxicity: Allergic Reactions01:30

Drug Toxicity: Allergic Reactions

223
Drug-related allergies are immune-mediated responses triggered by the administration of pharmacological agents. These hypersensitivity reactions are classified based on the immune mechanisms involved. The four primary types—Type I, II, III, and IV—are mediated by different immunological pathways and exhibit distinct clinical manifestations.Type I Hypersensitivity/ IgE-Mediated Reactions: Immunoglobulin E (IgE) immediately mediates Type I hypersensitivity reactions. Upon initial...

Area of Science:

  • Immunology
  • Virology
  • Pathology

Background:

  • Accumulating evidence suggests HIV-induced chronic immune activation is a key driver of AIDS progression.
  • The immune system's response, not viral cytopathicity, differentiates pathological from non-pathological infections in primate models.

Purpose of the Study:

  • To review mechanisms of chronic immune activation in HIV infection.
  • To discuss the impact of immune activation on HIV-specific immunity and disease progression.
  • To explore the role of inflammation in AIDS and non-AIDS related pathologies.

Main Methods:

  • Review of current scientific literature on HIV pathogenesis and immune activation.
  • Analysis of studies investigating immune responses in HIV-infected individuals and animal models.

Main Results:

  • Chronic immune activation involves various cell types and mechanisms.
  • Persistent inflammation contributes to both AIDS progression and non-AIDS related comorbidities.
  • HIV-specific immunity can be impaired by chronic immune activation.

Conclusions:

  • Therapeutic strategies targeting inflammation may be beneficial in managing HIV disease.
  • Reducing inflammation could delay HIV progression and mitigate associated pathologies.
  • Understanding immune activation is crucial for developing effective HIV treatments.
