[Expression of Langerhans cell-related chemokine genes in condyloma acuminatum epidermis].

Aim: To investigate differential gene expression of Langerhans cell-related chemokines in condyloma acuminatum (CA) epidermis and normal epidermis.

Methods: Gene expression of Langerhans cell-related chemokines in three CA epidermal lesions and in three normal controls was screened using Affymetrix oligonucleotide microarrays HG-U 133A 2.0, and part of the above differential gene expression was confirmed by semi-quantitative RT-PCR.

Results: With microarrays, seven down-regulated genes of Langerhans cell-related chemokine were detected in three CA epidermal lesions as compared with three normal controls, and the down-regulation of CXCR4 and CCL20 was verified by semi-quantitative RT-PCR.

Conclusion: Several Langerhans cell-related chemokine genes are found down-regulated in CA epidermis as compared with normal epidermis, and the down-regulation of these genes may contribute to the decreased number and the homing disturbance of LC in CA epidermis.
