This technology includes identification of the wild mouse microbiome as a method to increase resistance to lethal viral infection. We establish that the gut microbiome of barrier-raised C57BL/6 mice is dysbiotic compared to that of their outbred, wild-living progenitors, Mus musculus domesticus. We find that the multigenerational offspring of pregnant germfree C57BL/6 mice reconstituted with the gut microbiome of wild mice exhibit a less inflammatory response and increased survival following influenza A virus infection.

This technology includes an immunoassay to measure SARS-CoV-2 antibodies against the nucleocapsid and spike proteins.

This technology includes a system for automatic artifact-free measurement and visualization of tissue strain by MRI at native resolution. The investigation of regional soft tissue mechanical strain can serve as a unique indicator for different related disorders. For example, measurement of myocardial tissue during contraction can help calculate, track, and assess cardiac stress. Currently, methods such as tagging MRI (tMRI) are used for imaging soft tissue deformation. Despite being well validated, methods such as tMRI suffer from low spatial and temporal resolution.

Local inflammation processes are crucially important in the host defense against pathogens and for successful immunization because proinflammatory cytokines are necessary for initiation and propagation of an immune response. However, normal inflammatory responses are eventually terminated by physiological termination mechanisms, thereby limiting the strength and duration of immune responses, especially to weak antigens. The inventors have shown that adenosine A2a and A3a receptors play a critical role in down-regulation of inflammation in vivo.

Homocystinuria (HCU), a group of inherited disorders, causes symptoms ranging from failure to thrive and developmental delays in infants or young children to abnormal blood clots with onset in adults.1 Approximately 1 in 200,000 to 335,000 people have HCU globally.2

Patient conditioning is a critical initial step in hematopoietic stem and progenitor cell (HSPC) transplantation procedures to enable marrow engraftment of infused cells. Conditioning regimens have traditionally been achieved by delivering cytotoxic doses of chemotherapeutic agents and radiation. However, these regimens are associated with significant morbidity and mortality, and cannot be used safely in elderly or subjects with comorbidities.

Although flaviviruses cause a great deal of human suffering and economic loss, there is a shortage of effective vaccines. The present invention is directed toward vector stage replication-defective flaviviruses that are replication-defective in mosquito vectors that transmit them to humans. The replication-defective flaviviruses of the present invention demonstrate a limited ability to replicate in the vector organisms that transmit flaviviruses from one host to another.

The current invention provides a nucleic acid sequence comprising the genome of infectious hepatitis C viruses (HCV) of genotype 2a. The encoded polyprotein differs from those of the infectious clones of genotypes 1a and 1b (U.S. Patent 6,153,421) by approximately thirty (30) percent. It covers the use of this sequence and polypeptides encoded by all or part of the sequence, in the development of vaccines and diagnostic assays for HCV and the development of screening assays for the identification of antiviral agents for HCV. Additional information can be found in Yanagi et al.

The current invention provides nucleic acid sequences comprising the genomes of infectious GB virus B, the most closely related member of the Flaviviridae to hepatitis C virus (HCV). It also covers chimeric GBVB-HCV sequences and polypeptides for use in the development of vaccines and diagnostic assays for HCV and the development of screening assays for the identification of antiviral agents for HCV. Additional information can be found in Bukh et al. (1999), Virology 262, 470-478.

The current invention provides nucleic acid sequences comprising chimeric viral genome of hepatitis C Virus (HCV) and bovine viral diarrhea viruses (BVDV). The chimeric viruses are produced by replacing the structural region or a structural gene of an infectious BVDV clone with the corresponding region or gene of an infectious HCV. It covers the use of these sequences and polypeptides encoded by all or part of the sequences in the development of vaccines and diagnostic assays for HCV and the development of screening assays for the identification of antiviral agents for HCV.
