The viral tropism is also manifested by the clinical signs like occulo-nasal discharges diarrhea oral erosive lesions marked immuno-suppression and leucopenia; while viral antigen can be found in lymphoid organs and epithelial tissues of the affected animals (Kumar et al.
Limiting analysis to the V3 loop of gp120 is less difficult but may yield less accurate results since regions outside V3 are also involved in viral tropism.
Differential Induction of the KSHV Lytic Cycle in Skin Cells Suggests Cell Line-Specific Correlates of Viral Tropism.
