Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs

2.1K
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...

Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal01:22

Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal

2.7K
Erythropoietin-producing hepatocellular carcinoma receptor (Eph) and its ligand, Eph receptor-interacting protein (Ephrin) were first discovered in the human carcinoma cell line, hence the name. Ephrin-Eph interaction guides cells to reach their appropriate location in adult tissues. They also play an essential role in the immune system by helping in immune cell migration, adhesion, and activation. Based on their structure and function, Eph is divided into two classes — EphA and EphB.

Mesenchymal Stem Cells01:19

Mesenchymal Stem Cells

5.7K
Mesenchymal stem cells (MSCs) are adult stem cells that can differentiate into most connective tissue cell types, except for hematopoietic cells, depending upon the source of MSCs. For example, bone-marrow-derived MSCs (BM-MSCs) can differentiate into osteocytes, hepatocytes, and pancreatic and neuronal cells. MSCs can be isolated from various sources such as bone marrow, placenta, adipose tissue, teeth, and Wharton’s jelly, a gelatinous substance in the umbilical cord. The ease of their...

Clinical Applications of Epidermal Stem Cells01:19

Clinical Applications of Epidermal Stem Cells

3.4K
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...

Area of Science:

  • Immunology
  • Pharmacology
  • Cell Biology

Background:

  • Mast cells play a key role in allergic inflammatory responses.
  • Stem cell factor (SCF) mediates mast cell differentiation and migration.
  • The anti-allergic effects of beta-eudesmol on SCF-mediated reactions require further investigation.

Purpose of the Study:

  • To investigate the effects of beta-eudesmol on SCF-induced mast cell migration and inflammatory mediator production.
  • To elucidate the underlying molecular mechanisms of beta-eudesmol's anti-allergic activity.

Main Methods:

  • Rat peritoneal mast cells (RPMCs) were treated with beta-eudesmol and SCF.
  • Mast cell migration, F-actin formation, and inflammatory cytokine production were assessed.
  • The activation of Fyn kinase, Rac1 GTPase, and p38 MAPK was analyzed.

Main Results:

  • Beta-eudesmol suppressed SCF-induced mast cell migration and morphological changes in a dose-dependent manner.
  • Beta-eudesmol reduced F-actin formation and inhibited the activation of Fyn, Rac1, and p38 MAPK.
  • SCF-induced production of tumor necrosis factor-α and intercellular adhesion molecule-1 was abolished by beta-eudesmol without cytotoxicity.

Conclusions:

  • Beta-eudesmol exhibits anti-allergic effects by inhibiting mast cell migration.
  • Beta-eudesmol suppresses inflammatory cytokine production, suggesting therapeutic potential for allergic diseases.
