Abstract
Giant condyloma acuminatum, also known as Buschke-Lowenstein tumor (BLT), is a rare disease of the anogenital region. BLT is considered a locally aggressive tumor of benign histological appearance, but with the potential for destructive growth and high recurrence rates. BLT development is strongly associated with infection with low-risk human papillomaviruses (HPVs), mostly HPV-6 and -11. Immunity to HPVs plays a crucial role in the natural control of various HPV-induced lesions. Large condyloma acuminata are frequently reported in patients with primary (e.g., DOCK8 or SPINK5 deficiencies) and secondary (e.g., AIDS, solid organ transplantation) immune defects. Individuals with extensive anogenital warts, including BLT in particular, should therefore be tested for inherited or acquired immunodeficiency. Research into the genetic basis of unexplained cases is warranted. An understanding of the etiology of BLT would lead to improvements in its management. This review focuses on the role of underlying HPV infections, and human genetic and immunological determinants of BLT.

Abstract
We have reported previously that a 636-bp fragment spanning the 5' two-thirds of the human papillomavirus type 6 (HPV6)-W50 long control region (LCR) functions as a transcriptional silencer (A. Farr, S. Pattison, B.-S. Youn, and A. Roman, J. Gen. Virol. 76:827-835, 1995). We have utilized nested deletion analyses to implicate a 66-bp sequence which appears to be critical for this activity. A comparison of the transcriptional regulatory activities of the LCRs of HPV6-W50 and HPV6b (which has a 94-bp deletion, resulting in the elimination of the 66-bp sequence) indicates that sequences within the 94-bp region negatively regulate the activity of the intact HPV6 LCR. Two sequence-specific DNA-protein interactions were visualized via electrophoretic mobility shift assays. One of the binding events is mediated by the transcriptional repressor CCAAT displacement protein (CDP), a factor which is active in undifferentiated cells but inactive in terminally differentiated cells. This conclusion is based on the following three lines of evidence: (i) a consensus CDP binding site oligonucleotide serves as a competitor in band shift assays, (ii) the band shift complex is not seen when a CDP-negative nuclear extract is used, and (iii) anti-CDP antiserum specifically inhibits the binding. These studies identify a DNA-protein interaction occurring within the 5' end of the LCR which may be important in maintaining the tight link between keratinocyte differentiation and HPV gene expression.
