Caprine arthritis-encephalitis virus (CAEV) is a monocyte/macrophage tropic lentivirus which causes an immune-mediated disease complex in domestic goats characterized mainly by progressive arthritis of carpal joints. Joint lesions caused by CAEV consist of synovial membrane hyperplasia and villous hypertrophy with extensive angiogenesis and perivascular infiltration of mononuclear cells accompanied by significant cortical hyperplasia of regional lymph nodes. The mononuclear cell phenotypes, comprising perivascular infiltrates, include MHC class II activated macrophages, CD4+ and CD8+ ab T lymphocytes, and, predominantly, B lymphocytes and plasma cells. CAEV-induced arthritis follows a chronic, progressive course with clinical signs of periarticular swelling, accumulation of synovial fluid containing inflammatory cells and radiographic changes of soft tissue mineralization, and erosion of articular surfaces. Lesions contain CAEV infected macrophages8 and virus are readily recovered from synovial fluid, synovial fluid cells, and explants of synovial tissue. Previous studies have established that immune responses to CAEV envelope glycoproteins contribute to the development of arthritis.
