Autologous rosette formation in systemic lupus erythematosus
Acta Medica Hungarica
|January 1, 1983
Summary
Patients with Systemic Lupus Erythematosus (SLE) have fewer T lymphocytes that recognize their own cells. Steroid hormones and SLE patient sera inhibit this cell function, potentially explaining immune dysregulation in SLE.
Area of Science:
- Immunology
- Cellular Biology
Background:
- Systemic Lupus Erythematosus (SLE) is an autoimmune disease characterized by immune dysregulation.
- Autologous rosette formation by lymphocytes is a marker of immune cell function.
Purpose of the Study:
- To investigate the number of autologous rosette forming cells in SLE patients.
- To examine the effects of steroid hormones and SLE patient sera on autologous rosette formation.
Main Methods:
- Studied autologous rosette forming cells in SLE patients and normal controls.
- Assessed the impact of in vivo and in vitro steroid hormone exposure.
- Evaluated the effect of pooled sera from SLE patients on rosette formation.
Main Results:
- SLE patients exhibited significantly lower numbers of T lymphocytes forming autologous rosettes compared to controls.
- Steroid hormones inhibited autologous rosette formation in both SLE patients and controls.
- SLE patient sera with high immunocomplex content reduced auto-rosette numbers.
Conclusions:
- Reduced numbers or impaired function of autologous rosette forming lymphocytes may contribute to immune dysregulation in SLE.
- These lymphocytes are critical for immune regulation, influencing helper and suppressor cell differentiation.
