T cell receptor signal strength in Treg and iNKT cell development demonstrated by a novel fluorescent reporter mouse
The ability of antigen receptors to engage self-ligands with varying affinity is crucial for lymphocyte development. To further explore this concept, we generated transgenic mice expressing GFP from the immediate early gene Nr4a1 (Nur77) locus. GFP was up-regulated in lymphocytes by antigen receptor stimulation but not by inflammatory stimuli. In T cells, GFP was induced during positive selecti...
متن کاملA novel medium-throughput biological assay system for HTLV-1 infectivity and drug discovery
Objective(s): Here, a reporter cell line containing two reporter vectors were developed, in order to monitor the Human T-Lymphotropic Virus type1(HTLV-1) infectivity and the cell viability simultaneously. Materials and Methods: The reporter cell line was constructed by stably transfected baby hamster's kidney cell line (BHK-21), with the genomes expressing two different reporters in separate pl...
متن کاملModulation of CD4+ T Cell Subsets by Euphorbia microciadia and Euphorbia osyridea Plant Extracts
Background: Euphorbia plants are traditionally used in folk medicine for infections, inflammation, and cancer. Objectives: To investigate the effects of the butanolic extracts of Euphorbia micorociadia and Euphorbia osyridea on specific transcription factors and cytokines expression of T cell subsets. Methods: Activated mouse splenocytes were cultured in the presence of non-cytotoxic concentrat...
متن کاملA Quantitative Study of the Effect of Electroporation on the Electropermeability and Cell Survival
Introduction: Electroporation is a practical technique used to transport the molecules across the cell membrane. The utilization of fluorescent molecules is the method widely used to evaluate the electropermeability of cell membrane as a result of pulse application. It is also possible to use mathematical methods to predict the changes caused in cell electropermeability as a result of the chang...
متن کاملModification of the FoxP3 Transcription Factor Principally Affects Inducible T Regulatory Cells in a Model of Experimental Autoimmune Encephalomyelitis
T regulatory (Treg) cells expressing the transcription factor FoxP3 play a key role in protection against autoimmune disease. GFP-FoxP3 reporter mice have been used widely to study the induction, function and stability of both thymically- and peripherally-induced Treg cells. The N-terminal modification of FoxP3, however, affects its interaction with transcriptional co-factors; this can alter Tr...
