Figure 1From: Development of genetically engineered iNKT cells expressing TCRs specific for the M. tuberculosis 38-kDa antigenCDR3 spectratyping of CD8+ T cell TCR α and β chain genes before and after stimulation with the Mtb 38-kDa antigen. The polyclonal Gaussian distribution of Vβ5 and Vα9 gene families (framed) before stimulation changed to a monoclonal proliferation peak after stimulation, indicating their specificity to the Mtb 38-kDa antigen.Back to article page
