ABSTRACT
%85, entered into the high sensitive group (30 cases), and the patients with negative PRA into control group. The fresh blood was collected, and PBMCs was collected by Ficoll method. Total RNA were extracted by one-step technique and purified. The total RNA in high sensitive group were labeled with Cy5-dUTP, and control group with Cy3-dUTP, then the cDNA probe was labeled by reverse transcript way. High throughout gene chip ((16 920)) was hybrided and scanned. Cy3/Cy5 image files were copied. Then fluorescent signal value of gene expressing was obtained, and differential expression genes were sifted.

RESULTS:

Among the differential expression 877 genes, there were up-regulated 88 genes and down- regulated 789 genes. The mechanism of high sensitive status in human immune system was analyzed by some function-known genes which coded NY-REN-55 antigen, CD100, defender against cell death 1, breast cancer resistance protein, transcriptional repressor, death domain containing protein, cyclophilin-33A, rapamycin-binding protein, heat shock protein 40, interferon-alpha receptor and STAT inhibitor-2.

CONCLUSIONS:

The effect of PBMCs in high sensitive status of human immune system in patients with uremia may be associated with recognition of auto-antigen,signal conduction, aggregation and differentiation of B lymphocyte, anti-apoptosis and resistance of immunosuppressant. [
