Study of CD4~+CD25~+ regulatory T cells in NIK mutated mice / 中国免疫学杂志

ABSTRACT

Objective:To study the relationship betwen the mechanism of autoimmune disease and CD4+CD25+ T cell population in NIK mutated mice-aly mice.Methods:NIK mutated mice-aly/aly mice were used as model,aly/+mice as NIK normal control;cell populations were determined by FACS and the thymus structure were analyzed by immunohistochemistry.Results:The CD4+CD25+CD8- population were remarkably decreased in aly mice;and the UEA-1 positive cells were absent in aly mice.Conclusion:The autoimmune disease in aly mice might be the result of deceased the CD4+CD25+ population;the UEA-1 positive cells might play an important role in the development of CD4+CD25+ population.
