However, several B cell lymphomas are accompanied by abnormally large, mostly non-clonal, T cell populations, as determined by CD3 staining, Thy-1 mRNA levels, and diverse T cell receptor (TCR) junctions, which may be the result of strong anti-tumor T cell responses and/or inflammation in the tumor microenvironment (Figures S4A–S4D). The gene discussed is THY1; the disease is B-cell non-Hodgkin lymphoma.
