Cutting Edge Cutting Edge: The Y Chromosome Controls the Age-Dependent Experimental Allergic Encephalomyelitis Sexual Dimorphism in SJL/J Mice
نویسندگان
چکیده
Multiple sclerosis is a sexually dimorphic, demyelinating disease of the CNS, and experimental allergic encephalomyelitis (EAE) is its principal autoimmune model. Young male SJL/J mice are relatively resistant to EAE whereas older males and SJL/J females of any age are susceptible. By comparing a wide age range of proteolipid protein peptide 139 –151 immunized mice, we found that female disease severity remains constant with age. In contrast, EAE disease severity increases with age in SJL/J males, with young males having significantly less severe disease and older males having significantly more disease than equivalently aged females. To determine whether the Y chromosome contributes to this sexual dimorphism, EAE was induced in consomic SJL/J mice carrying a B10.S Y chromosome (SJL.Y). EAE was significantly more severe in young male SJL.Y mice compared with young male SJL/J mice. These studies show that a Y chromosome-linked polymorphism controls the age-dependent EAE sexual dimorphism observed in SJL/J mice. The Journal of Immunology, 2009, 182: 1789 –1793.

Cutting edge: c-Kit signaling differentially regulates type 2 innate lymphoid cell accumulation and susceptibility to central nervous system demyelination in male and female SJL mice.
Multiple sclerosis preferentially affects women, and this sexual dimorphism is recapitulated in the SJL mouse model of multiple sclerosis, experimental autoimmune encephalomyelitis (EAE). In this study, we demonstrate that signaling through c-Kit exerts distinct effects on EAE susceptibility in male and female SJL mice. Previous studies in females show that Kit mutant (W/W(v)) mice are less sus...
