J‐LEAPS peptide and LEAPS dendritic cell vaccines
نویسندگان
چکیده
The J-LEAPS vaccines contain a peptide from β-2-microglobulin covalently attached to disease-related peptides of 8-30 amino acids which contain a T cell epitope. The J-LEAPS vaccines can initiate a protective Th1 immune response or modulate an ongoing Th17 autoimmune response to the peptide. J-LEAPS vaccines activate and direct the nature of the subsequent immune response by promoting the maturation of precursor cells into a unique type of dendritic cell that produces interleukin 12, but not IL-1 or tumour necrosis factor, and presents the antigenic peptide to T cells. Adoptive transfer of JgD-LEAPS dendritic cells, matured with an anti-HSV-1 vaccine, promoted antigen-specific Th1 protection against lethal challenge with the virus. J-LEAPS peptide immunogens and J-LEAPS dendritic cell vaccines have potential applications for antimicrobial prevention and therapy, treatment of autoimmune diseases, and for cancer immunotherapy.

J-LEAPS vaccines elicit antigen specific Th1 responses by promoting maturation of type 1 dendritic cells (DC1)
The J-LEAPS peptide vaccine platform allows development of vaccines that elicit antigen specific Th1 immune responses to the incorporated antigenic peptide by promoting the maturation of mouse and human precursors into type 1 dendritic cells (DC1). CD8 T cell epitopes are covalently attached to the J-immune cell binding ligand through a tri-glycine linker. J-LEAPS peptide vaccines have been tes...
متن کاملAntigen-activated dendritic cells ameliorate influenza A infections.
Influenza A viruses cause significant morbidity and mortality worldwide. There is a need for alternative or adjunct therapies, as resistance to currently used antiviral drugs is emerging rapidly. We tested ligand epitope antigen presentation system (LEAPS) technology as a new immune-based treatment for influenza virus infection in a mouse model. Influenza-J-LEAPS peptides were synthesized by co...
متن کاملLEAPS Vaccine Incorporating HER-2/neu Epitope Elicits Protection That Prevents and Limits Tumor Growth and Spread of Breast Cancer in a Mouse Model
The prototype J-LEAPS T cell vaccine for HER-2/neu breast cancer (J-HER) consists of the murine HER-2/neu66-74 H-2d CD8 T cell epitope covalently attached through a triglycine linker to the J-immune cell binding ligand (ICBL) (human β2 microglobulin38-50 peptide). The J-ICBL was chosen for its potential to promote Th1/Tc1 responses. In this proof-of-concept study, the ability of J-HER to preven...
متن کاملThe biomechanics of leaping in gibbons.
Gibbons are skilled brachiators but they are also highly capable leapers, crossing distances in excess of 10 m in the wild. Despite this impressive performance capability, no detailed biomechanical studies of leaping in gibbons have been undertaken to date. We measured ground reaction forces and derived kinematic parameters from high-speed videos during gibbon leaps in a captive zoo environment...
متن کاملGymnasts Utilize Visual and Auditory Information for Behavioural Synchronization in Trampolining
In synchronized trampolining, two gymnasts perform the same routine at the same time. While trained gymnasts are thought to coordinate their own movements with the movements of another gymnast by detecting relevant movement information, the question arises how visual and auditory information contribute to the emergence of synchronicity between both gymnasts. Therefore the aim of this study was ...
