abstract = {Maternal anti-Caspr2 (Contactin-associated protein-like 2)
antibodies have been associated with increased risk for
autism spectrum disorder (ASD). Previous studies have shown
that in utero exposure to anti-Caspr2 antibodies results in
a phenotype with ASD-like features in male mice. Here we ask
whether four newly generated antibodies against Caspr2 are
pathogenic to the developing fetal brain and whether they
function through similar means. Our results show that these
novel anti-Caspr2 antibodies recognize different epitopes of
Caspr2. In utero exposure to these antibodies elicits
differential behavioral phenotypes in male offspring, as
demonstrated in the social interaction task, as well as
phenotypic alterations in the open-field and light-dark
tasks. These results demonstrate variability in the
antigenic specificity and pathogenicity of anti-Caspr2
antibodies which may have clinical implications.},
