[Granulocyte migration in vitro in psoriasis patients induced by aromatic retinoid]
Abstract:
The influence of the aromatic retinoid Ro 10-9359 on the migration of neutrophilic granulocytes was examined in standardized supravital preparation. For this purpose, leukocytes were taken from 5 psoriasis patients who had been treated with 75 mg of aromatic retinoid for 3 weeks. The examinations showed that the course of granulocyte migration was disturbed: the dormant stage was prolonged up to several hours. Maximum cell motility was already reached in that stage of motion in which the granulocytes maintained a constantly changing and bizarre cell pattern. The migration stage, which is characterized by a directed linear cell movement, was absent. Leukocyte survival time was shortened by 50%, and cell degeneration was abnormal under the influence of the aromatic retinoid.
Insights
The aromatic retinoid Ro 10-9359 significantly impairs neutrophilic granulocyte migration and survival in psoriasis patients. This drug disrupts normal cell movement, shortens survival time, and causes abnormal degeneration.
Area of Science:
- Immunology
- Dermatology
- Pharmacology
Context:
- Investigating the effects of aromatic retinoids on immune cells.
- Focusing on patients with psoriasis undergoing retinoid treatment.
- Utilizing standardized supravital preparations for cell analysis.
Purpose:
- To evaluate the impact of aromatic retinoid Ro 10-9359 on neutrophilic granulocyte migration.
- To assess changes in leukocyte survival and cell morphology.
- To understand the cellular mechanisms affected by this retinoid therapy.
Summary:
- Aromatic retinoid Ro 10-9359 treatment prolonged granulocyte dormancy and altered cell motility patterns.
- The characteristic directed linear migration of granulocytes was notably absent.
- Leukocyte survival time decreased by 50%, with observed abnormal cell degeneration.
Impact:
- Reveals detrimental effects of aromatic retinoids on neutrophil function.
- Suggests potential mechanisms for altered immune responses in retinoid-treated patients.
- Highlights the need for further investigation into retinoid-induced immunomodulation.
