[Expression of CD1a and CD207 in condyloma acuminatum epidermis].

AIM: To investigate the expression of CD1a and CD207 in condyloma acuminatum (CA) epidermis and to understand its significance.

METHODS

The mRNA expression of CD1a and CD207 in six CA epidermal lesions and in six normal controls were detected using oligonucleotide microarrys and confirmed by semi-quantitative RT-PCR, and the protein level of CD1a and CD207 in six CA epidermal lesions and in six normal controls were measured by Western blot.

RESULTS

With microarrys, the mRNA expression of CD1a and CD207 were detected markedly down-regulated in six CA epidermal lesions as compared with that in six normal controls. Moreover, the down-regulation of CD1a and CD207 was verified by semi-quantitative RT-PCR. Western blot analysis showed that the protein expression of CD1a and CD207 in six CA epidermal lesions were significantly lower than that in normal controls.

CONCLUSION

The expression of CD1a and CD207 is markedly down-regulated in CA epidermis compared with that in normal epidermis, and the results may suggest that the number of LC in CA epidermis is decreased and the function is impaired.
