In order to clarify the origin of JC virus-induced brain tumors in rats, the development of tumors was sequentially analyzed histologically and immunohistochemically. Twenty-two of 30 rats (73%), which were intracerebrally inoculated with JC virus within 24 h of birth (group 1), developed, as a group, 45 brain tumors after 12 to 26 weeks. Seventeen of 27 rats (63%), which were inoculated on the...
BACKGROUND Treatment with natalizumab, an antibody blocking the α4-integrin, is associated with increased numbers of circulating CD34+ cells in the peripheral blood of patients with multiple sclerosis. OBJECTIVE To determine whether natalizumab mobilizes CD34+ cells from or inhibits homing to the bone marrow (BM). DESIGN Fifty-two patients with relapsing-remitting multiple sclerosis treated...
We amplified and sequenced the genome of a polyomavirus infecting a central chimpanzee (Pan troglodytes troglodytes). This virus, which is closely related to BK and JC polyomaviruses, may help shed a new light on these human pathogens' evolutionary history.
Forty eight renal transplant recipients were investigated prospectively for evidence of infection with the polyomaviruses BK and JC and cytomegalovirus. An active polyomavirus infection was shown in 31 patients (65%) and cytomegalovirus in 30 (62.5%). Half of the BK and JC virus infections occurred within the first three months after transplantation compared with 93% of the cytomegalovirus infe...
