  • Patent number: 11077131
    Abstract: The disclosure is based on the finding that compounds capable of binding to (or interacting with) chromatin binding/remodelling complexes (for example Polycomb group PRC1 and Trithorax group MLL) and/or modulation of the same can be used to modulate (for example switch on/off) ciliogenesis as may occur, for example, in the human pulmonary bronchial epithelium. Provided are compounds, compositions, methods and medicaments which may be used to treat and/or prevent diseases and/or conditions associated with aberrant or defective ciliogenesis.

  • Publication number: 20110008287
    Abstract: The current invention provides improved methods and means for the treatment of virally induced intraepithelial neoplasias of the anogenital tract, such as HPV induced vulvar, cervical, vaginal, penile and anal intraepithelial neoplasias (VIN, CIN, VAIN, PIN and AIN). The invention provides a method of treatment of a subject suffering from an anogenital intraepithelial neoplasia comprising at least the steps of first determining whether the subject has a T-cell reactivity for viral early antigens, in particular high risk type HPV antigens; and subsequently a local treatment of the neoplasia with immune modulating compounds eliciting local inflammation if the subject scores positive for the T-cell reactivity, preferably a CD4+ response against HPV early antigens. The invention also comprises methods and means to induce or further stimulate a cellular immune response against HPV antigens, prior to or during treatment with the immune modulating compound capable of eliciting a local inflammatory response.
