Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs

2.4K
Asthma is a chronic respiratory condition for which new therapeutic avenues, including anti-inflammatory drugs like mast cell stabilizers and anti-IgE treatments, continue to be developed.
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...

T Cell Types and Functions01:24

T Cell Types and Functions

3.2K
When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.
Th1 cells stimulate dendritic cells to express necessary co-stimulatory molecules on their surfaces for...

Autoimmune Disorders01:29

Autoimmune Disorders

2.4K
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

Chronic Inflammation: Introduction01:12

Chronic Inflammation: Introduction

41
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...

Summary

Mast cells are key players in allergic reactions. Emerging evidence suggests these immune cells also coordinate early stages of autoimmune diseases, especially those with auto-antibodies.

Area of Science:

  • Immunology
  • Allergy Research
  • Autoimmune Disease Pathogenesis

Background:

  • Mast cells are recognized as central mediators of allergic responses.
  • Their role in initiating and amplifying allergic reactions to allergens is well-established.
  • Recent findings suggest a potential involvement of mast cells beyond allergy.

Purpose of the Study:

  • To explore the emerging role of mast cells in autoimmune diseases.
  • To investigate the potential involvement of mast cells in the early phases of autoimmunity.
  • To understand how mast cells might coordinate autoimmune responses, particularly those mediated by auto-antibodies.

Main Methods:

  • Review of recent immunological and clinical observations.
  • Analysis of experimental data linking mast cell activation to autoimmune conditions.

  • Comparative study of mast cell function in allergic versus autoimmune contexts.

    • Main Results:

    • Mast cells orchestrate robust responses even to minimal allergen exposure.
    • Observations indicate mast cells may play a crucial role in the initial stages of autoimmune diseases.
    • This role appears particularly significant in autoimmune diseases characterized by auto-antibodies.

    Conclusions:

    • Mast cells are not only central to allergy but also emerging as critical regulators in autoimmunity.
    • Their function in coordinating early autoimmune responses warrants further investigation.
    • Targeting mast cells could offer novel therapeutic strategies for autoimmune diseases involving auto-antibodies.
