(a) The numbers of exosomes in the conditioned medium of SH-SY5Y cells treated with or without plant Cers following siRNA-induced knockdown of LAPTM4B. Data were normalized to the control and are represented as the mean ± S.D. (n = 4). ** p < 0.01 (versus the Control siRNA). (b) A representative image of protein-ceramide overlay assay using GST-fused LAPTM4B and the indicated Cers. (c) The signal intensity of each dot was analyzed, and the data were represented as the mean ± S.D. (n = 3; * p < 0.05, ** p < 0.01, *** p < 0.001, versus Control). au; arbitrary unit.
