Expression of swine leucocyte antigen (SLA) class II in dominant-negative mutant class II transactivator (CIITA-DN) pig organs. Staining for SLA class II DR (FITC: green) and nuclei (DAPI: blue) in tissues from CIITA-DN and wild-type (WT) pigs was determined by fluorescence microscopy. Expression of SLA class II DR in CIITA-DN pigs was considerably weaker than in WT pigs in all tissues. Results are representative of at least two independent experiments.
