Cladribine Exposure Results in a Sustained Modulation of the Cytokine Response in Human Peripheral Blood Mononuclear Cells.

ABSTRACT:

Background and objectives

Cladribine is a cytotoxic drug which ameliorates the clinical course of relapsing-remitting multiple sclerosis. In addition to cytotoxicity, the mode of action may include immunomodulatory mechanisms. This in vitro study was designed to investigate cladribine's effects on cell function after the removal of cladribine to distinguish cytotoxic versus immunomodulatory effects.

Methods

Cells were incubated in the absence or presence of cladribine (1 × 10(-8) M to 1 × 10(-5) M) for 72 h. Cladribine was removed from the cell culture and surviving peripheral blood mononuclear cells were cultured up to 58 days to determine the immunomodulatory effects of cladribine on cell function (e.g., proliferation and cytokine release).

Results

In the long-term,
