  • This invention discloses methods and compositions to detect Toll-like receptor (TLR) binding to ligands and evaluate compound for screening. Using different biosensor complexes, this technology enables the diagnosis of gram positive or negative infections in a human subject. Each platform utilizes a TLR conjugated to a biosensor that detects a single TLR-ligand binding domain complementary to its cognate ligand. This technology can provide a method to select appropriate treatment for a patient with inflammatory and possibly other conditions.

Title: INTRACELLULAR DNA RECEPTORUMMS09-11; Patent 8,334,101

  • The innate immune system recognizes non-self genetic material and mounts a defensive immune response. However, self cytosolic DNA at times gets targeted and the process by which this phenomenon occurs has been largely unknown. The inventors have discovered PISA (PYHIN protein stimulating ASC), a receptor found to be necessary for activation of the ACS/caspase-1 axis of innate immunity in response to recognition of self cytosolic DNA. This invention discloses methods for identification and compounds found to modulate the PISA receptor and it’s downstream immune response.

Title: Use of Cathepsin B Inhibitors for the Treatment of IL-1 Related Diseases. UMMS08-51; Patent Pending.  

  • This innovation describes detailed mechanisms of how immune cells recognize microorganisms (non-self) from host (self). The cytoplasmic receptor complex NALP3 inflammasome has been found to react to a variety of crystals such as silica crystals or cholesterol crystals, all of which were found to require phagocytosis for activation. By inhibiting phagosomal acidification, the inventors were able to prevent activation of NALP3 in the presence of the crystal activators. Understanding these mechanisms may be valuable to research into IL-1 related diseases of sterile inflammation including atherlosclerosis, amyloidosis, Alzheimer silicosis, asbestosis and others.
