Latest Patents

One of Sikora's latest patents is titled "Use of cross-protection to identify novel vaccine candidates for infectious agents." This invention discloses methods for identifying vaccine candidates, enabling quality assurance for vaccine batches, assessment of protection in vaccinates, and identification of the infecting agent in vaccinates. In his research, mice were first vaccinated with an O-polysaccharide (OPS) vaccine. These animals were then given 10 lethal doses of a live vaccine strain (LVS). Remarkably, sixty percent of the vaccinated mice survived the multiple lethal doses. Sera were collected from these surviving mice, and the antibodies were used to probe supernatant and cell lysates of live LVS cultures. Several components were identified only by the noted 'survivor' antisera. Among these identified proteins, enzyme digestions and chemical oxidation suggest post-translational modifications of some proteins, including a 52 kDa glycoprotein, a 45 kDa lipoprotein, and a 19 kDa nucleoprotein. The 52 kDa component caused nitrous oxide induction in tissue cultures at low concentrations and cell death at high concentrations. Vaccination with this component provided partial protection, while the addition of other components acted synergistically to enhance protection from 250 lethal doses of LVS.
