  • Patent number: 11693018
    Abstract: Methods for testing a red blood cell (RBC) unit for release for transfusion into a subject are described. The methods allow management of the blood supply by assessing the viability of an RBC unit by its levels of dicarboxylic fatty acids (DFA). The methods include testing an RBC sample from an RBC unit for levels of DFA and discarding the RBC unit or releasing or not releasing the RBC unit for transfusion based on the results.

  • Patent number: 11397183
    Abstract: The instant disclosure provides biomarkers and methods for identifying subjects at risk of developing cytokine release syndrome (CRS), neurotoxicity, or both after adoptive immunotherapy to guide preemptive intervention, modified therapy, or the like. For example, adverse event biomarkers may be measured in a subject before pre-conditioning chemotherapy, before immunotherapy (e.g., adoptive immunotherapy infusion comprising a chimeric antigen receptor (CAR) modified T cell), or shortly after pre-conditioning chemotherapy and/or immunotherapy. Exemplary biomarkers include temperature, cytokine levels and endothelial activation biomarkers, such as angiopoietin 2, von Willebrand factor (vWF), ratio of angiopoietin 2 to angiopoietin 1, and ratio of ADAMTS13 to vWF. Also provided are methods of treating subjects identified as at risk of developing cytokine release syndrome (CRS), neurotoxicity, or both to minimize such potential adverse events.

  • Patent number: 11105820
    Abstract: Photonic devices, systems, and methods for detecting an analyte in a biological solution (e.g., whole blood) are provided. Representative photonic devices are optical ring resonators having nanoscale features and micron-sized diameters. Due to the compact size of these devices, many resonators can be disposed on a single substrate and tested simultaneously as a sample is passed over the devices. Typical analytes include blood cells, antibodies, and pathogens, as well as compounds indicative of the presence of blood cells or pathogens (e.g., serology). In certain embodiments, blood type can be determined through photonic sensing using a combination of direct detection of blood cells and serology. By combining the detection signals of multiple devices, the type of blood can be determined.

  • Publication number: 20210041463
    Abstract: The current disclosure provides compositions, systems, and methods for detection and/or identification of antibodies. Also provided are compositions, systems, and methods that expedite and simplify processes to identify blood units that are clinically appropriate for transfusion into a recipient, and more generally to identify the presence of antibody(s) in blood that are specific for selected antigen(s). The systems and methods utilize genetically-modified (transgenic) non-target-organism red blood cells that express at least one antigen of the target organism species. This enables screening and identifying blood units faster, more consistently, at large scale, and/or with less dependence on human involvement.
