Software System for Quantitative Assessment of Vasculature in Three 
Dimensional Images

    Description of Invention: This invention offered for licensing and 
further development is a software system that provides the capability 
of efficiently extracting, visualizing and quantifying three 
dimensional vascular networks from medical and basic research images. 
Deregulation of angiogenesis plays a major role in a number of human 
diseases, most notably cancer. A substantial increase in the research 
effort in this field over the past decade has deepened the 
understanding of the angiogenic process. However, the lack of methods 
and software to quantitatively assess vasculature in patients has 
considerably hampered the ability to directly study the angiogenesis 
process, as well as to discover and develop new therapeutics to 
modulate angiogenesis. The present

invention provides new semi-automated computer algorithms, statistical 
methods and user friendly visualization tools for rapid and intuitive 
quantitative evaluation of vasculature in three dimensional data sets 
obtained through non-invasive imaging techniques such as MRI, CT-Scans, 
confocal microscopy, microCT, etc. The methods and software embodied in 
this invention provide a three dimensional quantitative capability in 
the clinic as a vascular diagnostic tool and in basic research projects 
to evaluate changes in vascular network systems.
    Applications:
     Medical research for studying angiogenesis and tumor 
vasculature.
     Potential applications in clinical studies and 
diagnostics.
     Discovery and development of anti-angiogenesis agents with 
application to cancer.
     Possible application to diseases other than cancer, such 
as those related to the lymphatic system, the pulmonary airway, the 
kidney filtration system.
    Development Status:
     The invention is fully developed.
     The software will be readily available if so requested.
    Inventors: Enrique Zudaire, Christopher Kurcz, Yanling Liu (NCI).
    Patent Status: HHS Reference No. E-261-2010/0--Software. Patent 
protection is not being pursued for this technology.
    Licensing Status: Available for licensing.

Compounds That Treat Malaria and Prevent Malaria Transmission

    Technology Summary: The invention offered for licensing relates to 
therapeutic compounds and related pharmaceutical compositions that can 
be used in the prevention and treatment of malaria infection. More 
specifically, the invention is drawn to compounds that can kill malaria 
gametocytes to block malaria transmission and treat malaria infection 
in the non-erthtrocytic stages, as well as therapeutic uses of these 
molecules to prevent or slow the transmission of plasmodium organisms 
between mammals and eliminate or prevent infection in mammal. 
Furthermore, the compounds of the invention are tricyclic compounds 
where the side rings may be 5-7 membered rings (preferably 6-membered), 
and the center ring may be 6-8 membered ring (preferably 7-membered). 
Also preferable structures are ones in which the side rings are aryl 
rings while the center ring is cycloalkyl ring. The compounds of the 
invention have been identified by integrating quantitative high-
throughput screening (qHTS) with genetic mapping and in vivo oocyst 
formation assay.
    Applications: Prevention and treatment of malaria infections.
    Inventors: Xin-zhuan Su and Jing Yuan (NIAID).

A Universal Antigen Delivery Platform for Enhanced Immune Response

    Description of Invention: The present invention relates to use of 
the rotavirus NSP2 octamer as a universal antigen delivery platform for 
presenting a high density of neutralizing epitopes to the immune 
system, a strategy for boosting antigen immunogenicity. This 
application is advanced by the well-defined structural and biochemical 
properties of the octamer, its high stability at a broad range of pH, 
temperature and ionic stability, and its ease of purification (one 
step) under nondenaturing conditions. Long conformationally-dependent 
antigens are readily mounted onto the platform by fusion to the C-
terminus of NSP2, a region of the NSP2 protein positioned on the 
exposed surface of the octamer. The platform can be expressed in and 
purified from prokaryotic and eukaryotic systems.
    This technology can be used for rapid production of subunit 
vaccines against a wide range of infectious agents. Additional uses of 
the technology include the generation of delivery platforms with 
mounted short peptide antigens for use in cancer immunotherapy, 
production of specific antisera to conformationally and 
nonconformationally-dependent antigens for research purposes, and 
development of epitope targets and short peptide-antigen presentation 
platforms for diagnostic assays.
    Applications:
     Vaccines against pathogens.
     Cancer vaccines.
     Antigen-specific antisera.
     Multivalent targets in diagnostic assays.
    Advantages:
     Octameric platform is stable, efficiently expressed, and 
easily purified by a single step method.
     Enables the display of multivalent conformation-dependent 
epitopes.
     Effective platform for short peptides as well as long 
polypeptides.
    Development Status: Proof-of-concept experiments have shown that 
the octamer mounted with short peptides or long multivalent 
polypeptides retains its structural and biophysical features and is 
highly effective in presenting foreign antigens to the immune system. 
Ease of purification and final protein yields of the short or long 
peptide antigen-mounted NSP2 octamers were comparable suggesting that 
the platform accommodates a large range of antigen sizes. The NSP2-
platform also served as an adjuvant, significantly enhancing immunity 
of the mounted peptide.
