J Virol
. 2009 Apr;
83(12):6079-86.
PMID: 19339354
A small group of ecotropic murine retroviruses cause a spongiform neurodegenerative disease manifested by tremor, paralysis, and wasting. The neurovirulence of these viruses has long been known to be determined...

Fujisawa R, McAtee F, Favara C, Hayes S, Portis J
J Virol
. 2001 Oct;
75(22):11239-43.
PMID: 11602765
Glycosylated Gag (Glycogag) is a transmembrane protein encoded by murine and feline oncornaviruses. While the protein is dispensible for virus replication, Glycogag-null mutants of a neurovirulent murine oncornavirus are slow...

Peterson K, Robertson S, Portis J, Chesebro B
J Virol
. 2001 Feb;
75(6):2848-56.
PMID: 11222710
Infection of the central nervous system (CNS) by several viruses can lead to upregulation of proinflammatory cytokines and chemokines. In immunocompetent adults, these molecules induce prominent inflammatory infiltrates. However, with...

Askovic S, Favara C, McAtee F, Portis J
J Virol
. 2001 Feb;
75(6):2665-74.
PMID: 11222690
The chimeric murine oncornavirus FrCas(E) causes a rapidly progressive paralytic disease associated with spongiform neurodegeneration throughout the neuroaxis. Neurovirulence is determined by the sequence of the viral envelope gene and...

Infect Immun
. 2001 Feb;
69(3):1832-40.
PMID: 11179361
Immunization(s) fostering the induction of genital mucosa-targeted immune effectors is the goal of vaccines against sexually transmitted diseases. However, it is uncertain whether vaccine administration should be based on the...

Lynch W, Portis J
Virology
. 2000 Jun;
271(2):227-33.
PMID: 10860875
The discovery within the past decade that neural stem cells (NSCs) from the developing and adult mammalian brain can be propagated, cloned, and genetically manipulated ex vivo for ultimate transfer...

Askovic S, McAtee F, Favara C, Portis J
J Virol
. 1999 Dec;
74(1):465-73.
PMID: 10590136
The chimeric murine oncornavirus FrCas(E) causes a rapidly progressive noninflammatory spongiform encephalomyelopathy after neonatal inoculation. The virus was constructed by the introduction of pol-env sequences from the wild mouse virus...
