Cancer immunity induction system
31 Oct 2022
A research group at Osaka Metropolitan University has developed a drug delivery system that activates a strong cellular immune response to attack cancer cells, using one-tenth of the amount of antigen needed in the group’s previous work. By incorporating positively charged cationic lipids into liposomes and adding negatively charged pH-responsive polysaccharides to the surface, the research group increased the uptake efficiency of liposomes encapsulating cancer antigens by dendritic cells by approximately five times, which increased cytokine production by about 100 times. This increased M1-type macrophages, which activate cancer immunity, and decreased M2-type macrophages, which promote cancer growth.

Osaka Metropolitan University scientists have successfully developed a new positive electrode material Na2FeS2, consisting of sodium, iron, and sulfur. During testing, batteries using the Na2FeS2 positive electrode had a high energy storage capacity and could be charged and discharged for more than 300 cycles. Because the Na2FeS2 is made of abundant inexpensive elements, it is expected to be used in all-solid-state sodium batteries with higher capacity and lower costs.

Osaka Metropolitan University researchers have successfully synthesized fumarate (fumaric acid), a raw material for unsaturated polyester resin, by combining carbon dioxide (CO2) with pyruvate (derived from biomass), using two biocatalysts: malate dehydrogenase and fumarase. Fumarate is currently used to make biodegradable plastic like polybutylene succinate from petroleum. However, this research has enabled the synthesis of fumarate without petroleum, consuming only CO2 and biomass-derived pyruvate.

Osaka Metropolitan University researchers have clarified the first suitable computational conditions for Adiabatic State Preparation (ASP) executable on a quantum computer, a method that can improve the accuracy of calculating atomic and molecular wave functions. ASP is thought to be one of the leading methods for efficiently preparing correlated wave functions of molecules with complex electronic structures, but the specific conditions required for the calculations have not been thoroughly investigated so far. This new research has clarified the computational conditions needed to use ASP, a major development for making quantum chemical calculations on a quantum computer practical for chemical or materials research.
