Epstein-Barr virus is associated with several human malignancies including Burkitt's lymphoma, nasopharyngeal carcinoma, and Hodgkin's disease (HD). To examine the effect of Epstein-Barr virus nuclear antigen 1 (EBNA-1) in the pathogenesis of HD, we transfected the gene into the HD cell line L428. EBNA-1 expression was associated with significantly enhanced CD25 expression (interleukin 2 [IL-2]-receptor alpha chain) in transient and stably transfected L428 cells but did not affect the expression of IL-2 receptor beta and gamma chains. There was no up-regulation of the B-cell activation molecules CD23, CD30, CD39, CD40, CD44, CD71, and CD54 (intercellular adhesion molecule 1) or enhanced production of IL-6, IL-10, lymphotoxin alpha, and the soluble form of CD25. Stable EBNA-1-expressing L428 cells were nontumorigenic in SCID mice but showed enhanced lymphoma development in nonobese diabetic-SCID mice compared to mock-transfected cells.

To study gene expression within the mammary glands of dairy goats with mastitis, mRNA was collected from milk somatic cells (MSCs) of left udder halves challenged with Staphylococcus aureus and right udder halves infused with PBS, as control, at different time points (0, 12, 24 and 48h post-infection). Transcriptional profiles were investigated using bovine cDNA microarrays; of the total 288 differentially expressed genes identified with ANOVA analysis (False Discovery Rate=0.05, 1.5-fold change), 26, 36 and 16 genes were down-regulated at 12, 24 and 48h post-infection, respectively, while 60, 141 and 9 genes were up-regulated at the same corresponding time points. The expression profiles clearly changed at 24h post-infection with 177 genes significantly altered, corresponding to a 10-fold increase of S. aureus bacterial count in milk from infected udders. Differential expression of selected genes (CD2BP2, BCAP31, MHCII, FOSL2, MAPK13, ILT5 and JUNB) was also confirmed by real-time PCR at the different time points considered, showing high correlation with the microarray measurements and high reliability of the microarray analyses. The most readily inducible classes of genes in caprine MSCs infected with S. aureus were pro-inflammatory cytokines, chemokines and their receptors; IL-1alpha, lymphotoxin alpha, granulocyte chemotactic protein (CXCL6), and IL-2 receptor gamma were all up-regulated in infected udders versus healthy controls. This study identified a number of differentially expressed genes induced by S. aureus intramammary infection and demonstrates the intricacy of the patterns of gene expression that influence host response to a complex pathogen of significant relevance to both human and veterinary medicine.
