Purpose
MRI cell tracking can be used to monitor immune cells involved in the immunotherapy response, providing insight into the mechanism of action, temporal progression of tumor growth, and individual potency of therapies. To evaluate whether MRI could be used to track immune cell populations in response to immunotherapy, CD8+ cytotoxic T cells, CD4+CD25+FoxP3+ regulatory T cells, and myeloid‐derived...
Immunotherapies, including peptide-based vaccines, are a growing area of cancer research, and understanding their mechanism of action is crucial for their continued development and clinical application. Exploring the biodistribution of vaccine components may be key to understanding this action. This work used magnetic resonance imaging (MRI) to characterize the in vivo biodistribution of the antigen...
ObjectiveTo investigate P‐ and E‐selectin ligand coexpression with chemokine receptors (CKRs) on T cells in the synovial fluid (SF) and blood of children with juvenile idiopathic arthritis (JIA).
MethodsSixteen patients with polyarticular or persistent oligoarticular JIA (ages 5.3–15.1 years) were studied. SF and venous blood were collected, and immunostaining for the expression of CCR4, CCR5, CXCR3,...
Nucleic acid vaccines represent a promising alternative to killed bacterial antigen, recombinant protein or peptide vaccines for infectious diseases and cancer immunotherapy. Although significant advances are made with DNA vaccines in animal studies, there are severe limitations to deliver these vaccines effectively and considerable reservations exist about current methods used. In this study, a liposome-based...
