74 results about "Proteasome degradation" patented technology

Proteasomes are part of a major mechanism by which cells regulate the concentration of particular proteins and degrade misfolded proteins. Proteins are tagged for degradation with a small protein called ubiquitin. The tagging reaction is catalyzed by enzymes called ubiquitin ligases.

Treatment of protein degradation disorders

The invention relates to methods of treating protein degradation disorders, such cellular proliferative disorders (e.g., cancer) and protein deposition disorders (e.g., neurodegenerative disorders). The invention provides methods and pharmaceutical compositions for treating these diseases using aggresome inhibitors or combinations of aggresome inhibitors and proteasome inhibitors. The invention further relates to methods and pharmaceutical compositions for treating multiple myeloma. New HDAC / TDAC inhibitors and aggresome inhibitors are also provided as well as synthetic methodologies for preparing these compounds.

Methods For Producing Dendritic Cells That Have Acquired Ctl-Inducing Ability

The present inventors worked on elucidating the mechanism of antigen cross-presentation by dendritic cells, and revealed that foreign antigens taken up in dendritic cells are degraded by proteasomes after undergoing polyubiquitination. Based on the novel finding that polyubiquitination is involved in cross-presentation, the promotion of polyubiquitination was attempted by a number of methods, and the promotion of antigen presentation was confirmed. These methods enable the production of dendritic cells effective for inducing CTL activation.
