Flow cytometric characterization of Ag-specific T cells typically relies on detection of protein analytes. ...Shifting the analysis to detection of RNA would provide several significant advantages, which we illustrate by developing a new host immunity–based platform for detection of infections. ...Cytokine mRNAs synthesized in response to ex vivo stimulation with pathogen-specific Ags are detected in T cells with single–molecule fluorescence in situ hybridization followed by flow cytometry. ...Background from pre-existing in vivo analytes is lower for RNAs than for proteins, allowing greater sensitivity for detection of low-frequency cells. ...The utility of probing immunological memory of infections is demonstrated by detecting T cells that recognize mycobacterial and viral Ags in donors exposed to the respective pathogens.

Glycogen synthase kinase-3 controls IL-10 expression in CD4(+) effector T-cell subsets through epigenetic modification of the IL-10 promoter.
Hill, E. V., et al. Eur J Immunol. 2015 Apr;45(4):1103-15. doi: 10.1002/eji.201444661. PMID: 25627813
To investigate the requirement for APCs during GSK3 inhibition mediated induction of IL-10 in CD4+ T cells, naive or polarized Tg4 CD4+ T cells were cultured with anti-CD3/ anti-CD28 stimulation in the presence of GSK3 inhibitors and IL-10 secretion was assessed. ...(A) Naive CD4+ T cells were isolated from Tg4 splenocytes and cultured with anti-CD3 and anti-CD28 in the presence of IL-2 and GSK3 inhibitors or vehicle control. ...NS, not significant (ANOVA). (B) Th1 polarized Tg4 cells were restimulated with anti-CD3 and anti-CD28 in the presence of IL-2 and GSK3 inhibitors or vehicle control. ...Alternatively, live CD4+ T cells were isolated by Ficoll centrifugation and then magnetic separation using the CD4+ T cell Isolation kit II and restimulated with either anti-CD3 and anti-CD28 coated beads (Dynabeads, Life Technologies) or on anti-CD3 (1 μg/mL, eBioscience; clone 145-2C11) and anti-CD28 (2 μg/mL, eBioscience; clone 37.51) coated plates. ...Total mRNA from 3–5 × 106 CD4+ T cells after overnight anti-CD3 and anti-CD28 stimulation was isolated using RNAeasy Mini Kit (Qiagen) and quality and quantity were verified using a Nanodrop (Thermo scientific).
