2A and fig. 2C). The CD19+ cell expression of HERV-W Env TM epitopes was also significantly higher in both group of MS patients but only when compared with healthy controls (p = 0.02). CD14+ cell expression of HERV-H Env TM was significantly higher in both MS patient groups compared with neurological non-inflammatory disease controls (p ≤ 0.05). The gene discussed is CD19; the disease is myeloid sarcoma.
