ABSTRACT
OBJECTIVES:
Tacrolimus (TAC) is the most widely used immunosuppressive agent after lung transplantation. Considering that the ciliary beat frequency (CBF) mainly depends on the cytoplasmic calcium concentration and that TAC can affect this due to its binding with the intracellular immunophilin FKBP12, we hypothesized that TAC could also impair the airway mucociliary clearance of rats.METHODS:
Sixty rats were divided into two groups (n = 30 each) Control = water; TAC = tacrolimus. After 7, 15 or 30 days of treatment, ten animals from each group were euthanized and the following parameters were studied mucus transportability, CBF, mucociliary transport velocity (MCTV), and neutral and acid mucus production.RESULTS:
There was a significant decrease in CBF (Control vs TAC 7 days, p = 0.008; 15 days, p = 0.007; 30 days, p = 0.001) and MCTV (Control vs TAC 7 days, p = 0.004; 15 days, p < 0.001; 30 days, p < 0.001) in all immunosuppressed animals. TAC therapy also caused an increase in acid mucus production at all treatment times (Control vs TAC 7 days, p = 0.001; 15 days, p = 0.043; 30 days, p = 0.001).CONCLUSIONS:
TAC impairs airway mucociliary clearance of rats.Palavras-chave
