| 1 | Albumin fusion with granulocyte-macrophage colony-stimulating factor acts as an immunotherapy against chronic tuberculosis显示文摘A long duration of treatment and emerging drug resistance pose significant challenges for global tuberculosis(TB)eradication efforts.Therefore,there is an urgent need to develop novel strategies to shorten TB treatment regimens and to treat drug-resistant TB.Using an albumin-fusion strategy,we created a novel albumin-fused granulocyte-macrophage colony-stimulating factor(albGM-CSF)molecule that harnesses albumin’s long half-life and targeting abilities to enhance the biostability of GM-CSF and direct it to the lymph nodes,where the effects of GM-CSF can increase dendritic cell populations crucial for eliciting a potent immune response.In this study,we demonstrate that albGM-CSF serves as a novel immunotherapy for chronic Mycobacterium tuberculosis(Mtb)infections by enhancing GM-CSF biostability in serum.Specifically,albumin is very safe,stable,and has a long half-life,thereby enhancing the biostability of GM-CSF.In the lungs and draining lymph nodes,albGM-CSF is able to increase the numbers of dendritic cells,which are crucial for the activation of naive T cells and for eliciting potent immune responses.Subcutaneous administration of albGM-CSF alone reduced the mean lung bacillary burden in mice with chronic tuberculosis infection.While GM-CSF administration was associated with IL-1βrelease from Mtb-infected dendritic cells and macrophages,higher IL-1βlevels were observed in albGM-CSF-treated mice with chronic tuberculosis infection than in mice receiving GM-CSF.Albumin fusion with GM-CSF represents a promising strategy for the control of chronic lung tuberculosis infections and serves as a novel therapeutic vaccination platform for other infectious diseases and malignancies. | Yu-Min Chuang Liangmei He Michael L.Pinn Ya-Chea Tsai Max A.Cheng Emily Farmer Petros C.Karakousis Chien-Fu Hung | 2021 | Cellular & Molecular Immunology2021，18，10： | 3 |
