Recurrent clinical uveitis. Cell surface markers on vitreous lymphocytes
Archives of Ophthalmology (Chicago, Ill. : 1960)
|April 1, 1982
Summary
In chronic idiopathic uveitis, most vitreous cells are B cells and macrophages, identified by surface immunoglobulin and phagocytosis. Few T cells were detected, indicating a specific immune cell profile in this condition.
Area of Science:
- Ophthalmology
- Immunology
- Cell Biology
Background:
- Chronic idiopathic uveitis is an inflammatory eye condition.
- Understanding the immune cell infiltrate in the vitreous is crucial for managing uveitis.
Purpose of the Study:
- To characterize the cell surface markers of mononuclear cells in the vitreous of patients with chronic idiopathic uveitis.
- To identify the predominant immune cell types present in the affected vitreous.
Main Methods:
- Analysis of vitreous samples from ten patients with chronic idiopathic uveitis.
- Determination of cell surface characteristics, including surface immunoglobulin, phagocytosis, and E rosette formation.
Main Results:
- The majority of vitreous mononuclear cells expressed surface immunoglobulin, suggesting B cell lineage.
- A significant proportion of cells demonstrated phagocytic activity, indicative of macrophages.
- Few cells formed E rosettes, indicating a low presence of T cells.
Conclusions:
- The predominant immune cells in the vitreous of chronic idiopathic uveitis are B cells and macrophages.
- The limited presence of T cells suggests a specific immune response pattern in this condition.
