Tubular expression of heat-shock protein 27 inhibits fibrogenesis in obstructive nephropathy.

Morphological changes that occur during kidney injury involve actin skeleton remodeling. Here we tested whether heat-shock protein 27 (HSP27), a small stress response protein involved in cytoskeletal remodeling, protects the kidney from tubulointerstitial fibrosis in obstructive nephropathy. Tubular cell HSP27 immunostaining was significantly increased in human kidneys with ureteropelvic junction obstruction, supporting the clinical relevance of our studies.

Identification of equine herpesvirus-1 antigens recognized by cytotoxic T lymphocytes.

Equine herpesvirus-1 (EHV-1) causes serious disease in horses throughout the world, despite the frequent use of vaccines. CTLs are thought to be critical for protection from primary and reactivating latent EHV-1 infections. However, the antigen-specificity of EHV-1-specific CTLs is unknown.
