Stem Cell Related Patent Number US5112607
| Title: | Potentiation of immunotoxin action by Brefeldin A | | Inventors: | Hudson, Thomas H.; Bethesda, MD, USA
King, Michael A.; Laurel, MD, USA | | Summary: | Described herein is a process for potentiating immunotoxin action via the use of small, non-toxic concentrations of Brefeldin A. The invention provides methods and materials for the use of Brefeldin A as an immunopotentiator in an immunotoxin or target-cell stem wherein the Brefeldin A has been shown to enhance the immunotoxin pathway while blocking or inhibiting the nonspecific pathway. Further disclosed are methods by which Brefeldin A has been shown to potentiate the cytotoxicity of toxic A chains containing conjugates. Therapeutic applications are included for the in vivo and in vitro use of Brefeldin A in conjunction with immunotoxins made from holotoxins. | | Abstract: | A method of potentiating immunotoxin action in an immunotoxin/target-cell stem in which Brefeldin A is utilized as an immunopotentiator. The Brefeldin A enhances the immunotoxin pathway while blocking or inhibiting the nonspecific pathway, thus being particularly useful in conjunction with immunotoxins made from holotoxins. The Brefeldin A is effective in small, nontoxic concentrations and therefore may be utilized with either in vivo or in vitro systems. | | US Patent Website: | Click Here for Full Text of Patent | | Title Number: | US5112607 | | Application Number: | US1991000715094 | | Date Filed: | 05/06/1991 | | Date Published: | 12/05/1992 | | Assignee: | The USA as represented by the Secretary of the Army, Washington, DC, USA |
