TCR-Vβ13+ T cells increase in abundance during diabetes progression in LEW.1WR1 islets. To determine the relative abundance of Vβ13+ T cells in the islet during progression to diabetes, we measured TCR-Vβ13 transcript abundance and normalized this to the abundance of TCR-Cβ transcripts. This measure gives us the percentage of TCR transcripts that are Vβ13+. There is a strong positive trend in Vβ13 transcript abundance with a significant increase on day 10 in both the diabetic (P = 0.02) and nondiabetic (P = 0.001) islet. N = 3–5 rats per time point, 29 rats total. D, day; diab, diabetes.
