PDLIM7 and myasthenia gravis: To characterize the phenotype of EBV-infected cells, detected in MG thymomas by in situ hybridization for EBERs and EBNA1-specific immunostaining, we performed double immunofluorescence staining to localize the EBV latency membrane proteins LMP1 and LMP2A in B cells and TECs, the possible cell targets of EBV infection.
