ABSTRACT
The peripheral blood distribution of T cell subsets was evaluated in a group of patients with primary IgA nephropathy (IgAN). Results showed that the frequency of helper (CD4+) and suppressor (CD8+) T lymphocytes in IgAN overlapped that seen in healthy blood donors. In addition, the helper T cell subset (CD4+ CDW29+ and CD4+ CD45R+ cells, respectively) proportion was normal, while with particular reference to suppressor T cell subpopulations, a significant decrease of CD8+ CD11+ lymphocytes (the true suppressor cells) was observed in IgAN. These data were further confirmed by the demonstration that monocyte chemotactic responsiveness triggered by lymphocyte-derived chemotactic factor (LDCF), a lymphokine released by CD8+ CD11- cells, was higher in IgAN than in controls. These data suggest that the low frequency of CD8+ CD11+ cells may be responsible for the impaired T cell immunoregulatory activity in patients with IgAN.
