Publication number: 20150374714Abstract: Nanoparticles containing a photosensitizer configured to generate a reactive oxygen species when exposed to an appropriate wavelength of light can be used to enhance immunogenicity of cancer cells, such as breast cancer cells. Such enhanced immunogenicity cancer cells, or supernatants thereof, can be used to activate dendritic cells or cause dendritic cells to produce INF-gamma. Nanoparticles having mitochondria-targeting moieties are more effective at enhancing the immunogenicity of the cancer cells, or causing the dendritic cells to produce IFN-gamma, than nanoparticle lacking mitochondria-targeting moieties or free photo sensitizer.Type: ApplicationFiled: February 11, 2014Publication date: December 31, 2015Inventors: Shanta Dhar, Sean Marrache, Donald A. Harn, Smanla Tundup

Publication number: 20140315781Abstract: The present invention provides a compound comprising a helminth-derived glycan and/or glycoconjugate thereof (e.g., a compound comprising a Lewisx antigen (e.g., LNFPIII), a non-Lewisx antigen (e.g., LNnT, LDN, and LDN derivatives), or a mixture of Lewisx and non-Lewisx antigens (e.g., SEA)), useful as a therapeutic compound for treating or preventing diseases associated with fat accumulation in the liver. The compounds of the invention are useful for treating or preventing the development of a fatty liver disease in a subject that has the disease or is at risk of developing the disease, and inhibiting lipogenesis in hepatocytes. The invention also provides methods of regulating the Erk-c-fos/AP-1-FXR? signalling pathway by administering a compound comprising a helminth-derived glycan and/or glycoconjugate thereof to a subject with a fatty liver disease, or contacting a hepatocyte with a compound comprising a helminth-derived glycan and/or glycoconjugate thereof.Type: ApplicationFiled: September 21, 2012Publication date: October 23, 2014Applicant: PRESIDENT AND FELLOWS OF HARVARD COLLEGEInventors: Chih-hao Lee, Prerna Bhargava, Donald A.

Patent number: 7799755Abstract: Methods for modulating immune responses are provided. The methods involve contacting an immune cell with an agent that modulates interaction of a compound comprising a Lewis antigen with the immune cell such that production by the immune cell of at least one cytokine that regulates development of a T helper type 1 or T helper type 2 response is modulated. In one embodiment, the agent is a stimulatory form of a compound comprising a Lewis antigen, such as a Lewisy, Lewisx or Lewisa oligosaccharide, or a derivative thereof. In another embodiment, the agent is an inhibitory form of a compound comprising a Lewis antigen, such as a Lewisy, Lewisx or Lewisa oligosaccharide, or a derivative thereof. In various embodiments, the immune cell is a human immune cell, a macrophage or a T cell. Pharmaceutical compositions for modulating immune responses are also provided.Type: GrantFiled: July 11, 2006Date of Patent: September 21, 2010Assignee: The President and Fellows of Harvard CollegeInventors: Donald A. Harn, Palanivel Velupillai

Publication number: 20080057061Abstract: We have discovered that targeting carbohydrates on cell, or viral particle surfaces, such as using antibodies against such carbohydrates also called glycans provide a new tool to treat diseases and disorders, such as viral diseases and malignant tumors. Therefore, the present invention provides methods for treating individuals affected with diseases and disorders, for example viral infections, such as lentiviral infections, and malignant tumors, using molecules that bind carbohydrates that are expressed on the surface of the viral particle or a cell, for example antibodies against Lewis X-antigen.Type: ApplicationFiled: November 22, 2005Publication date: March 6, 2008Applicant: President and Fellows of Harvard CollegeInventor: Donald Harn
