Background: Decreased numbers of Langerhans cells (LCs) in the cervix of human immunodeficiency virus (HIV)-infected women are believed to contribute to the progression of human papilloma virus (HPV)-related squamous intraepithelial lesions. However, this impairment of local immunity has not been well studied in the vulva. The objective of this study was to compare the S100+ LC density in high-grade vulvar intraepithelial neoplasia (VIN) in HIV-positive and HIV-negative women.

Identifying molecular players in the host response to infection may enable the development of medical countermeasures against Y. pestis.

Sterol regulatory element binding proteins (SREBPs) are a family of transcription factors that regulate genes involved in lipid metabolism, including FAS. SREBP-1c expression is induced in liver and adipose tissue by insulin and by fasting/refeeding and is critical for nutritional regulation of lipogenic gene expression.

Relative to the more common breast cancers of no distinctive type (ductal carcinoma), mucinous cancers have a relatively favorable prognosis. In a study of chromosomal changes in mucinous cancers, we evaluated the extent of loss of heterozygosity (LOH) at chromosomal regions commonly deleted in usual infiltrating ductal carcinoma, including markers on chromosomal arms 1p, 1q, 3p, 6q, 8p, 9p, 11p, 11q, 13q, 16q, 17p, and 17q.
