LF 15-0195 treatment protects against central nervous system autoimmunity by favoring the development of Foxp3-expressing regulatory CD4 T cells.

Experimental autoimmune encephalomyelitis (EAE) is an instructive model for the human demyelinating disease multiple sclerosis. Lewis (LEW) rats immunized with myelin-basic protein (MBP) develop EAE characterized by a single episode of paralysis, from which they recover spontaneously and become refractory to a second induction of disease. LF 15-0195 is a novel molecule that has potent immunosuppressive effects in several immune-mediated pathological manifestations, including EAE.

Estrogen enhances susceptibility to experimental autoimmune myasthenia gravis by promoting type 1-polarized immune responses.

Myasthenia gravis (MG) is an organ-specific autoimmune disease caused in most cases by autoantibodies against the nicotinic acetylcholine receptor (AChR). It is now well documented that many autoimmune diseases, including MG, are more prevalent in women than in men, and that fluctuations in disease severity occur during pregnancy. These observations raise the question of the potential role of sex hormones, such as estrogens, as mediators of sex differences in autoimmunity.
