Synthetic Bacterial Nanoparticles as Drug and Vaccine Delivery Vehicles

Bacterial spores can be modified to display molecules of interest, including drugs, immunogenic peptides, antibodies and other functional proteins of interest (such as enzymes).  The resulting engineered bacterial spores can provide many useful functions such as the treatment of infections, use as an adjuvant for the delivery of vaccines, and the enzymatic degradation of environmental pollutants.

Devices for Improved Tissue Cryopreservation and Recovery

Problem: Cryopreservation is a process where living biological materials like cells, tissues, and cell therapies (which are susceptible to damage caused by unregulated chemical kinetics) are preserved by cooling to very low temperatures in the presence of specific cryopreservation media that protects the biological material from damage. In order to be used, the biological material ideally should be thawed in a controlled manner that minimizes damage and desirably brings the material back to a viable state.

T-Cell Immunotherapy that Targets Aggressive Epithelial Tumors

Metastatic cancers cause up to 90% of cancer deaths, yet few treatment options exist for patients with metastatic disease. Adoptive transfer of T cells that express tumor-reactive T-cell receptors (TCRs) has been shown to mediate regression of metastatic cancers in some patients. Unfortunately, identification of antigens expressed solely by cancer cells and not normal tissues has been a major challenge for the development of T-cell based immunotherapies. Thus, it is essential to find novel target antigens differentially expressed in cancer versus normal tissues.

Tissue Clamp for Repeated Opening and Closure of Incisions/Wounds

Medical clamps currently available are not efficient nor are they sufficiently precise in closure and alignment of the edges of an incision or wound. Many available designs are difficult to use and handle, especially in situations where repeated opening and closure of an incision or wound is required. The functional short-comings of existing clamp designs may result in surgical complications, such as excess loss of fluids and pressure and hemostasis during some procedures.

Griffithsin-Based Anti-viral Therapeutics with Improved Stability and Solubility

Griffithsin is a potent anti-viral protein with activity against HIV, HCV, Sars, HSV 1 & 2 and other viruses.  It is active against HIV and HCV at picomolar concentrations.  Griffithsin is moving into clinical trials as an anti-HIV microbicide. Based on the structure of griffithsin and the necessities of pharmaceutical product development and regulatory approval, certain mutations in the sequence of griffithsin have been generated which could add to the stability and solubility of the protein.

Anti-Py1235-Met Immunological Binding Reagent as Cancer Diagnostic

This technology consists of highly specific rabbit monoclonal antibodies reactive with phosphorylated tyrosine located at amino acid 1235 in the human MET sequence. Binding to this pYl235 residue is independent of the phosphorylation of other tyrosines in the vicinity (1230 and 1234), does not cross-react with these nearby phosphotyrosine residues, and does not occur when Y1235 is unphosphorylated.

Anti-bacterial Treatments Using Peptide-Based Inhibitors of the STAT3-IL10 Pathway

Tuberculosis (TB) is an infectious disease that typically affects the lungs. Current therapies include a panel of antibiotics given over a range of 6-9 months. As a result of the expense of treatment, the extended timeframe needed for effective treatment, and the scarcity of medicines in some developing countries, patient compliance with TB treatment is very low and results in multi-drug resistant TB (MDR-TB). There remains a need for a faster, more effective treatment for TB.

Methods of making and using dopamine receptor selective antagonists/partial agonists

Dopamine is a major neurotransmitter in the central nervous system and among other functions is directly related to the rewarding effects of drugs of abuse.  Dopamine signaling is mediated by D1, D2, D3, D4 and D5 receptors.  The dopamine D3 receptor is a known target to treat a variety of neuropsychiatric disorders, including substance use disorders (e.g. cocaine and opioid), schizophrenia and depression.
