Improved immunotherapy for breast cancer.

Monoclonal antibodies (mAbs) to ErbB-2/HER2 growth factor receptor, or to its sibling, the epidermal growth factor receptor (EGFR), prolong survival of cancer patients, especially when combined with cytotoxic therapies. However, low effectiveness of therapeutic mAbs and the evolution of patient resistance call for improvements. Furthermore, the response to the clinically approved monotherapy of Herceptin (a humanized mAb directed against ErbB-2), is relatively low (~15%) and short lived (median duration, 9 months). Therefore, there is a need to improve the therapeutic treatment against this receptor. The present technology enhances the therapeutic activity of anti-ErB-2 receptor antibodies, by combining two or more epitope-distinct antibodies.

Applications


  • Improved treatment of ErbB-2-overexpressing tumors (e.g. in breast and ovary cancers).


Advantages


  • May enhance patient response and delay acquisition of resistance.
  • Enhancement of therapeutic efficacy and synergy with chemotherapy.

Technology's Essence


Optimal selection of mAbs for cancer immunotherapy may improve its therapeutic potential. The outlined technology addresses an emerging strategy, which enhances the therapeutic activity of anti-receptor antibodies by combining two mAbs engaging distinct epitopes. It was demonstrated that pairs of anti-ErbB-2 mAbs better inhibit ErbB-2-overexpressing tumors than the respective individual mAbs, both in vitro and in vivo.

Label-free detection and monitoring of target molecules, which can be conducted using standard lab equipment. This new method of optical analysis is effective in monitoring the binding of chemically or physically adsorbed molecules, in liquid or gas phase, with measurements carried out continuously in real-time.

SPR and LSPR technologies are broadly used in efficient real-time detection and quantification of biomolecules in research environments; however these technologies are too complicated, cumbersome and expensive for routine applications. This novel technology combines real-time, high sensitivity and accuracy of LSPR with low cost and ease of use of other optical assays, such as ELISA.

The invention comprises the LSPR transducer element of a gold-island film biosensor, which does not suffer shortcomings such as extreme temperature sensitivity. The gold island film is rapidly integrated into lab consumables via a novel fabrication method, which produces a robust system for high-throughput molecular diagnostics.

Applications


  • Point of care, real time diagnostics of chemical and biological substances.
  • Environmental watch: monitoring air or water pollution, testing for food poisoning.
  • Chemical warfare: detection of chemical agents and explosives.
  • Real-time monitoring of marine biofouling or industry corrosion processes.

Advantages


  • Simple operation, versatile and inexpensive method to imbed sensor in standard lab consumables.
  • High-throughput label-free detection with sensitivity comparable to that of SPR.
  • Uses cheap, disposable samples.
  • Can be combined with a variety of biosensing technologies.

Technology's Essence


The method involves evaporation of ultrathin (?10 nm) gold films onto inert transparent substrates (e.g., glass, plastic) leading to the formation of a layer of gold islands. Gold-island films provide unique optical properties. Such films show a localized surface plasmon (LSP) absorption peak much less sensitive to the refractive index of the surrounding medium. The LSP absorption band changes upon binding of various molecules to the surface. The binding process can be followed quantitatively by measuring the changes in the gold SP absorption. Selective sensing using the LSPR method can be achieved by applying a thin layer containing receptor molecules onto the gold island film, and measuring changes in the SP absorption upon binding of a specific analyte to the receptor layer

In recent years, there has been a growing interest in the development of nanoscale magnetic and thermal characterization tools in order to address rapidly evolving fields, such as nanomagnetism, spintronics and energy-efficient computing. The requirements from these tools include high sensitivity and high spatial resolution to enable local detection and accurate measurements of extremely low signals. For example, the energy dissipation mechanism in quantum systems is related to preservation of quantum information, which is of particular importance in the field of quantum computing. Available local magnetic imaging methods suffer from low sensitivity and in some cases, low spatial resolution. On the other hand, energy dissipation is not a readily measurable quantity on the nanometer scale and existing thermal imaging methods are not sensitive enough for studying quantum systems and are unsuitable for low temperature operation.

A novel sensor device comprising a nanoscale superconducting quantum interference device (SQUID) was developed by Prof. Zeldov at the Weizmann Institute of Science. The fabrication method enables the miniaturization of the sensor to an effective diameter of below 50 nm and its integration onto the apex of a very sharp tip that is ideally suited for scanning probe microscopy. The extremely small size of the SQUID-on-tip sensor and the ability to approach very close to the sample surface result in nano-metric spatial resolution and a very sensitivity.

Applications


·         Scanning probe microscopy for magnetic and thermal characterization

·         Inspection and probing equipment for quantum computing


Advantages


  • Simple fabrication process

  • High field sensitivity and bandwidth

  • Nanoscale sensors (down to 46 nm in diameter)

  • Tip-sample distance can be as close as a few nanometers


Technology's Essence


A SQUID is a very sensitive magnetometer used to measure extremely subtle magnetic fields, based on superconducting loops. The present invention is a novel sensor device, based on a nanoscale two-junction or multi-junction SQUIDs fabricated on the edge of a sharp tip in a three dimensional geometric configuration. In such a setup, the SQUID can approach the sample to a distance of few nanometers, as opposed to the conventional planar SQUIDs, which results in an extremely high sensitivity.

New peptides for improving the recruitment of stem cells for transplantation.

Blood cancers (leukemia, lymphoma and myeloma) are very common: they accounted for nearly 9.5 percent of deaths in the US from cancer in 2009. Stem cell transplantation, which aims to restore the function of the marrow, is an important therapy for these malignancies. Successful blood and marrow transplant requires the infusion of a sufficient number of hematopoietic stem and progenitor cells (HSPC), which is done by recruitment of HSPC from the marrow into the blood (mobilization). Currently used clinical procedures to produce stem cell mobilization include administration of G-CSF or GM-CSF, either as single agents or in combination with chemotherapy. However, some autologous blood stem cell donors exhibit indifference to currently applied mobilization therapies. Hence, improved methods to mobilize peripheral blood HSPC are warranted. The present invention is directed to novel short peptides of beta-defensins for improving the mobilization of HSPC.

Applications


  • Rapid and efficient mobilization of HSPC for clinical transplantation
  • Inhibition of malignant cell proliferation and metastasis

Advantages


·         Non-toxic, derived from a physiological molecule of innate host immunity

·         Cheap and simple synthesis

·         Rapid, robust and preferential mobilization of immature HSPC

·         Enhancement of mobilizing efficiency of presently used substances (e.g. G-CSF)

·         Dual use of the derivatives


Technology's Essence


Beta-defensins belong to a family of antimicrobial peptides, a major component of the innate immune system. In a mouse model, two different linear beta-defensin-derived peptides provided a strong and rapid HSPC mobilization, alone and in combination with G-CSF, a cytokine that is the major agent inducing robust mobilization of HSPC. In addition, a cyclic peptide derivative effectively inhibited HSPC mobilization and proliferation, as well as human malignant cell motility in mice. These findings make beta-defensin-derived peptides as promising small molecule candidates for improving current clinical HSPC mobilization protocols, and their cyclic derivatives as promising candidates for reducing cancer cell development and metastasis in patients.
