Figure 3From: Induction of B-cell lymphoma by UVB Radiation in p53 Haploinsufficient Mice UVBL-1 cells exhibit a robust CSR in response to LPS stimulation. A. Flow cytometry analysis of untreated, 25 and 100 ng/ml LPS treated UVBL-1 cells undergo class switch recombination to IgG2b; B. Untreated, IL-4+CD40L and CD40L+TGFβ treated UVBL-1 cells class switch to IgG1 and IgA respectively.Back to article page
