Objective:
To study the changes of red cell immune function and T-lymphocyte subsets in children with bronchiolitis and their possible roles in the pathogenesis of bronchiolitis.
Methods:
Forty-five children with bronchiolitis and 30 healthy controls were enrolled. Red cell immune complex rosette (RBC-ICR) and red cell C3b receptor rosette (RBC-C3bRR) were detected. The percentages of CD3+, CD4+ and CD8+ cells were assayed by flow cytometry.
Results:
RBC-C3bRR[(13.6 ± 6.2)% vs (18.0 ± 7.4)%] and the percentage of CD8+ cells [(21.6 ± 4.4)% vs (25.6 ± 5.2) %] in the bronchiolitis group were lower than those in the control group (P<0.01). The percentage of CD3+ cells [(59.9 ± 6.7)% vs (52.1 ± 8.3)%] and CD4+ cells [(53.5 ± 6.2)% vs (46.8 ± 4.9)%] and RBC-ICR [(8.3 ± 3.5)% vs (6.1 ± 2.5)%] in the bronchiolitis group were higher than those in the control group (P<0.01). The percentage of CD4+ cells was positively correlated with RBC-ICR (r=0.63,P<0.05) and negatively correlated with RBC-C3bRR (r=-0.82,P<0.01).
Conclusions:
There are dysfunctions of red cell immune and T-lymphocyte subsets in children with brochiolitis, which may play a role in the pathogenesis of brochiolitis.

The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
