Abstract:
OBJECTIVETo study myeloid-derived suppressor cells (MDSC) levels in peripheral blood of infants with recurrent wheezing, and the role of MDSC in the development of recurrent wheezing.
METHODSThirty-one infants with recurrent wheezing at wheezing attacks were randomly enrolled in the study. Twenty-seven infants with bronchopneumonia and 27 preoperative infants (hernia or renal calculus), without infectious or neoplastic diseases, were selected as controls. The proportion of MDSC in peripheral blood mononuclear cells (PBMC) was measured by flow cytometry.
RESULTSThe proportion of MDSC in PBMC in infants with wheezing was significantly higher than in those with bronchopneumonia and preoperative infants (P<0.05).
CONCLUSIONSMDSC levels increase in infants with recurrent wheezing, suggesting that MDSC may play a crucial role in the development of this disorder.
