The DA strain of Theiler's murine encephalomyelitis virus persists in the white matter of the spinal cords of susceptible mice. Previous results showed that the difference in susceptibility to viral persistence between the susceptible SJL/J strain and the resistant B10.S strain was due to multiple non-H-2 loci. The respective roles of hematopoietic and nonhematopoietic cells in this difference have been evaluated with bone marrow chimeras. The results show that non-H-2 loci with a major effect on susceptibility are expressed in hematopoietic cells. However, the study of the SJL.B10-D10Mit180-D10Mit74 congenic line suggests that other loci expressed in nonhematopoietic cells also play a role.
泰勒氏小鼠脑脊髓炎病毒的DA株在易感小鼠脊髓的白质中持续存在。先前的结果表明,易感的SJL/J株和抗性的B10.S株对病毒持续感染的易感性差异是由多个非H-2基因座引起的。已经用骨髓嵌合体评估了造血细胞和非造血细胞在这种差异中的各自作用。结果表明,对易感性有主要影响的非H-2基因座在造血细胞中表达。然而,对SJL.B10-D10Mit180-D10Mit74同源系的研究表明,在非造血细胞中表达的其他基因座也起作用。
