Summary

Interferon beta significantly improves suppressor cell function in patients with progressive multiple sclerosis (MS). This finding offers a new therapeutic avenue for managing MS by enhancing immune cell activity.

Area of Science:

  • Immunology
  • Neuroimmunology
  • Cellular Immunology

Background:

  • Progressive multiple sclerosis (MS) is associated with decreased suppressor cell function.
  • This immune deficiency in MS patients is often resistant to in vitro correction and immunosuppressive therapies.

Purpose of the Study:

  • To investigate the effect of interferon beta on suppressor cell function in progressive multiple sclerosis.
  • To determine if recombinant human interferon beta can augment impaired immune suppressor activity in MS.

Main Methods:

  • Utilized a concanavalin A (Con A) suppressor assay to measure nonspecific suppressor cell function.
  • Compared suppressor cell function in 24 patients with progressive MS to 19 healthy control subjects.
  • Assessed the impact of adding recombinant human interferon beta (10(3) units/ml) to lymphocyte cultures.

Main Results:

  • MS patients exhibited significantly reduced suppressor cell function (19.6%) compared to controls (35.0%) (p < 0.001).
  • Recombinant human interferon beta significantly improved suppressor activity in MS patients, increasing mean suppression to 37.8% (p < 0.001).
  • Interferon beta also enhanced suppressor function in normal subjects, from 35.0% to 46.2% (p < 0.025).

Conclusions:

  • Recombinant human interferon beta demonstrates a significant ability to augment suppressor cell function in humans.
  • This immunomodulatory effect of interferon beta is particularly beneficial for individuals with progressive multiple sclerosis.
  • The findings suggest interferon beta as a potential therapeutic agent for restoring immune balance in MS.
