Syphilis is a highly contagious sexually transmitted disease caused by the bacterium, Treponema pallidum (T. pallidum). If left untreated, syphilis can cause serious complications including blindness, paralysis and dementia.

Syphilis is a sexually transmitted disease (STD) that remains a global health threat. Syphilis rates in the United States have also been increasing. Left untreated, syphilis infection can span decades and have serious complications including blindness, dementia and paralysis. Syphilis in pregnancy causes prematurity, low birthweight, neonatal death, and infections in newborns. Improvements in syphilis detection are needed to facilitate early diagnosis of active infections and monitor treatment with antibiotics.

Syphilis, a genital ulcerative disease caused by the bacterium Treponema pallidum, is associated with significant complications if left untreated. Syphilis rates in the United States have been increasing.

The VRC01-class of potent, broadly neutralizing antibodies (bnAbs) targets the conserved CD4-binding site (CD4bs) of HIV-1 Env which has been a major target of HIV-vaccine design. The current best priming immunogen to engage the VRC01-class germline precursors is the eOD-GT8 60mer, which elicits VRC01-class precursors in multiple transgenic mouse models. However, a large proportion of the antibodies elicited by eOD-GT8 60mer are non-CD4bs or “off-target” antibodies, undermining its effectiveness in eliciting the VRC01-class bnAb precursors.

Syphilis is a sexually transmitted infection that remains a global health threat. The World Health Organization estimates that more than 12 million new cases are reported in adults annually worldwide. Syphilis rates are rising domestically as well. The rapid plasma reagin (RPR) test (including automated version) and the Venereal Disease Research Laboratory (VDRL) test are commercially available and used to detect/screen active infection.

Multiple sclerosis (MS) is an autoimmune disease caused by activated autoimmune T lymphocytes in patients resulting in inflammatory demyelination in the central nervous system. Current treatments are focused on functional control of these activated autoimmune T cells, but these treatments are non-specific T cell inhibitors and have serious, sometimes fatal side effects. A specific therapy aimed at eliminating these autoimmune T cells through restimulation-induced cell death (RICD) could cure the disease and overcome the fatal side effects of current therapies.

Ebola virus (EBOV) hemorrhagic fever is one of the most lethal viral infections and lacks a licensed vaccine. EBOV is transmitted by contact with body fluids from infected individuals including droplets or aerosols. Aerosolized EBOV could also be exploited for intentional virus spread. Therefore, vaccines that protect against mucosal and systemic exposure are needed.

The inventors have created a reverse genetics system for RSV strain B1 of antigenic subgroup B encoding a replication-competent recombinant RSV that contains a codon-optimized G ORF and expresses enhanced green fluorescence protein (GFP). There are two antigenic subgroups of RSV, subgroups A and B, and most of the available information and reagents are for subgroup A. Immunity against either subgroup has reduced effectiveness in restricting the heterologous subgroup, suggesting that an effective RSV vaccine might need to contain both subgroups.

According to 2010-2014 World Health Organization (WHO) research, dog-transmitted human rabies was present or suspected in 150 countries and territories worldwide. Domestic dogs were the most common reservoir of the rabies virus in these countries, and more than 99% of human deaths were caused by dog-transmitted rabies. Rabies is 100% preventable in dogs with appropriate administration of vaccines.

In pursuit of an effective vaccine to end the global HIV-1/AIDS pandemic, researchers at the Vaccine Research Center (“VRC”) continue to study the structure of HIV-1. Recently, these researchers have determined the three-dimensional structure of the HIV-1 Envelope trimeric ectodomain (“Env”), comprised of three gp120 and three gp41 subunits, in its prefusion, mature, closed conformation.
