This innovative technology revolves around a novel vaccine development strategy for combating filoviruses, notorious for causing severe hemorrhagic fevers in humans and non-human primates. At the heart of this advancement is a modified vaccinia Ankara (MVA) vector, ingeniously engineered to encode specific viral antigens that trigger a protective immune response against various filoviruses, including the Sudan ebolavirus (SEBOV), Zaire ebolavirus (ZEBOV), and the Marburg virus.

This technology pertains to the strategic enhancement of HIV neutralizing antibodies through the insertion of specific amino acid substitutions. The substitutions, as described and potentially contributed by biotechnology companies such as Xencor, Genentech, and MedImmune, aim to extend the antibodies' half-life within serum and improve their Antibody-Dependent Cellular Cytotoxicity (ADCC) capabilities. This innovation has the potential to significantly improve the therapeutic and preventative efficacy of these antibodies against HIV.

The technology encompasses a novel set of fully human monoclonal antibodies targeting the spike (S) protein of coronaviruses, notably the SARS-CoV-2 virus responsible for COVID-19. These antibodies, derived from convalescent patients, offer potential for use in the diagnosis, monitoring, and treatment of coronavirus infections. This discovery includes a comprehensive library of antibody or antibody fragment candidates with high specificity for the coronavirus spike protein.

This technology includes genetically modified strains of Bdellovibrio and E. coli bacteria, along with associated plasmids, that have been engineered for antibiotic resistance. These modified bacterial strains and plasmids have been developed to replace specific genes with antibiotic resistance markers, allowing for more precise studies in genetic research, as well as the development and testing of new antibiotics.

In this study, the research explores the potential of PfCg4, a novel heat shock protein, as a candidate for a transmission-blocking malaria vaccine. By producing recombinant PfCg4 and conducting experiments demonstrating its susceptibility to antibody blockade in the mosquito midgut, the study presents evidence for its vaccine candidacy. This discovery holds promise for enhancing current efforts to combat malaria transmission and potentially offers cross-species transmission-blocking activity, given its similarity to the P. vivax Cg4 protein.

This technology summary highlights the pivotal role of replicons, cell lines, and reporter virus particles (RVPs) in advancing Flavivirus research. Replicons, engineered from the viral genome, allow for controlled replication in host cells, while cell lines stably harboring these replicons provide valuable tools for drug discovery and the production of pseudo-infectious virus particles. These RVPs, composed of flavivirus structural proteins, underpin a high-throughput quantitative method for studying antibody-mediated neutralization of infection.

This technology involves the development of live attenuated vaccine candidates for respiratory syncytial virus (RSV), a significant cause of severe respiratory tract diseases, particularly in infants and young children. The approach focuses on relocating the NS1 and NS2 genes within the RSV genome to downstream positions, resulting in reduced transcription and expression. This gene-shifting strategy allows for controlled attenuation of the virus, avoiding over-attenuation seen with gene deletion. Combining gene shifts with other mutations fine-tunes the level of attenuation.

This technology includes 8 novel strains of the species Streptococcus mitis, Streptococcus oralis, and Streptococcus infantis for vaccine or probiotic development. The capsular biosynthetic genes from each of these strains are highly related to pneumococcal counterparts encoding 5 capsular serotypes. All 8 of these non-pneumococcal strains were recovered from nasopharyngeal (NP) or oropharyngeal (OP) specimens.

This technology includes a real-time RT-PCR (reverse transcriptase – polymerase chain reaction) Taqman assay using primers and probes specific for EV-D68 viral protein 1 nucleic acid. This assay provides a more specific identification of EV-D68 strains allowing better diagnosis. Human Enterovirus D68 (EV-D68) is a non-polio enterovirus that can cause mild to severe respiratory illness, especially in infants and children with asthma. The assay is simple, validated, and allows rapid testing and detection of EV-D68 in respiratory samples.

This technology includes a compound, CDEU050, which has shown to have anti-Ebola virus activity in cell culture. CDEU050 is a novel small molecule, unrelated to any previously described inhibitor that blocks Ebola virus infection in cell culture.
