PTPγ regulation is unique among other RPTPs. Expression of PTPγ mRNA in comparison with a selection of RPTPs in resting and activated moMΦ and moDCs. Lane 1, marker; lane 2, resting macrophages; lane 3, macrophages activated with 100 ng/mL LPS for 24 hours; lane 4, resting DCs; lane 5, DCs activated with 100 ng/mL LPS for 24 hours. Names of the genes analyzed appear on the left side of the picture.
